A second reason to use a worm gear is the inability to reverse the direction of power. The bull gear 36 is connected in torque transmitting relation with the propeller shaft 14. At the same time when the control system begins to monitor the duration which begins with functional block 94, the astern clutch is set to a slip mode as shown by functional block 96. No. When connecting an Arduino Uno to the internet (ethernet) what are some attacks it's susceptible to and how can I secure against them? 10. These variably engageable clutches permit the prime mover to be connected to the propeller shaft in partial torque transmitting association. By permitting the propeller to be driven at this relatively low speed while the engine is being operated above its idle speed, the marine vessel can be maneuvered at slow speeds while certain deleterious conditions relating to tooth separation, which will be discussed below, can be avoided by increasing the engine speed above its idle speed. No. It is the maximum torque wich may be transmitted on input, corresponding to a theoretical unlimited gear life and to a bearing life (L10) of 5000 hours at least, with an input speed of 2000 RPM. In addition, the overlap of the astern clutch engagement and the brake engagement can be varied depending on the specific application. Prior to event 1, the engine and propeller are running at a speed, indicated by line 115, above their idle speed. In addition, the rotational speed of the propeller shaft can be controlled by regulating the rotational speed of the prime mover. 6 represents the propeller shaft speed equivalent to the engine idle RPM and dashed line 116 represents the desired rotational speed of the propeller shaft. In addition, prior art gearboxes do not employ clutches that can be operated in a partially engaged mode while the brake is fully engaged. Worm Gear Speed Reducer NEMA23-030 Reduction Gearbox Ratio Gear Box 50 60 80:1. Checked the battery voltage and all that, the battery is fully charged, etc. You don't want to have to take that transmission apart any more than you have to. In a preferred embodiment of the pre sent invention, the variable torque transmitting means comprises a variably engageable clutch. The pinion gears are connected in torque transmitting association with the propeller shaft. The gears will try to engage in a reverse motion but the high speed won't let that happen. When the astern clutch is fully engaged, the brake is fully disengaged and the rotational speed of the engine is commanded to increase. Might be intentional, to limit the forces on the rear end gear set, or in the tranny for that matter, in the non-normal driving direction. By definition, the variable engageable clutch is capable of partially transmitting torque from a prime mover to a load when the prime mover is operating at or above its idle speed. No. Typically, an input shaft of a marine reduction gearbox is connectible to the prime mover and is also connected to forward and reverse transfer gears. It should be understood that a fixed time delay could also be used to determine the proper time to engage the brake.

Through this connection, the bull gear 36 and the propeller shaft 14 are caused to rotate in a direction which causes the propeller shaft to move in a reverse or astern direction. In other words, most known clutches require some finite period of time to move from a completely disengaged state to a completely engaged state or vice versa. Student A says that if the carrier is the input and the sun gear is the reaction member, the ring gear will rotate in a gear reduction. No. 1 is used to identify the combination of components included in the reverse reduction gearbox of the present invention. In order for the ECM to enable the reverse . The present invention provides another significant benefit beside that which is described above relating to a crash reversal procedure. 4. In other words, the clutch is intended to operate for a preselected period of time between a state of complete disengagement and one of complete engagement. The vertical axes in FIG. The present invention is directed toward solving this problem. 4, an illustrative flow chart is shown which could be incorporated in a marine vessel control system utilizing the present system. The exemplary chronology shown in FIG. The status of the ahead clutch is illustrated by line 110 which repeatedly is alternated between fully engaged and fully disengaged. Thanks for contributing an answer to Engineering Stack Exchange! (1) Total Ratings 1, $369.99 New. It will typically take multiple reductions of a conventional gearset to achieve the same reduction level of a single worm gear - meaning users of worm gears have fewer moving parts and fewer places for failure. The factor by which speed is reduced is the ratio. The inclusion of this variably engageable clutch permits a control system to command the clutch to a partial torque transmitting position for a predetermined period of time. Why are protons, rather than electrons, the nucleus in atoms? To learn more, see our tips on writing great answers.

As can be seen in FIG. In addition, the engine achieves its idle speed approximately midway between events 2 and 3 as a result of its complete disengagement from the propeller. A forward, or ahead, transfer gear 20 and a reverse, or astern, transfer gear 22 are associated in torque transmitting relation with the input shaft 16. What is this grey status effect in Dark Souls Remastered? FALK CORPORATION, THE, 3001 WEST CANAL STREET, MIL, Free format text: Once partially engaged at event number 1, the variably engageable clutch of the present invention is caused to remain at this partial torque transmitting level of engagement. Marine reduction gearbox assemblies are used to transmit torque between a unidirectional prime mover and the propeller shaft of the marine vessel to provide bidirectional rotation capability for the propeller in association with the unidirectional prime mover. The gearbox of the present invention also comprises a means for connecting the marine reduction gearbox in torque transmitting association with a shaft of a marine propeller. The brake is continually monitored until it is sensed as being fully engaged and, when that occurs, a fixed time delay is initiated. The disengagement of the brake is illustrated by functional block 106 and the operation by which the RPM of the engine is increased is represented by functional block 108. The remotely operated boxes are known as Marinomatic and are hydraulically assisted. Two typical designs are Offset Gear Reduction and Planetary Gear Reduction. During this transition from disengagement to engagement, the rotating portions of the clutch move from a non-contact relation with other components of the clutch to a contact relation with those components. MathJax reference. Delayed Engagement, Reverse Drain Down N-R - P-R Delay 3-5-Reverse Clutch Piston Capacity Reduction - SOP 2008 model year. It also provides a disengageable clutch between the prime mover and the propeller for the purpose of transmitting power to the propeller for driving it in a forward direction. 6. Means are also provided to brake the system dynamically to speeds within the capacity of the frequency converter. Although the present invention has been described with significant detail and illustrated with considerable specificity, it should be understood that modifications of the preferred embodiment of the present are within its scope. As a result of the engagement of the brake 50, the propeller decelerates to a still condition, immediately prior to event number 3. 4,338,525, which issued to Kilgore on July 6, 1982, discloses a marine propulsion system that includes a gas turbine, an alternating current generator, a fixed pitch propeller, a synchronous motor and a frequency converter. This is illustrated by functional block 104. At event number 1, a crash reversal command is sent to the control system. A second advantage of the use of a variably engageable clutch is that a marine vessel can be operated at speeds lower than that which would result from direct connection between a prime mover operating at idle speed and a propeller shaft. 4,252,034, which issued to DeBruyne on Feb. 24, 1981, describes a free-floating planetary transmission with a reversible output. This type of clutch comprises a plurality of clutch plates, or discs, and is generally known to those skilled in the art for use in applications other than in marine reverse reduction gearboxes. The present invention, on the other hand, incorporates variably engageable clutches which are specifically designed for use in a slipping mode for predetermined periods of time without significant damage occurring to the clutches. This update limits the volume of oil required to stroke the piston. At speeds within the frequency converter's design capacity, the motor can be operated synchronously while it is running at a speed below the minimum operating speed of the turbine and generator. After the commands represented by functional blocks 100 and 102 are activated, the control system monitors the astern clutch to see if it is fully engaged. U.S. Pat. This sudden connection of the engine to the propeller shaft, while at idle RPM, could likely cause a high BMEP engine to stall or rotate in the opposite direction. For purposes of this description, the term "variable engageable clutch" shall mean a clutch of the type which is designed and intended for use in a manner which disposes various clutch plates of the clutch in a slipping association with other clutch plates. 2 are intended to represent percentages of full speed or full engagements rather than specific magnitudes. If "D" shows and Drive engages, then go back to Reverse. Furthermore, because of the operation of the present invention, the propeller does not experience the windmilling effect which is illustrated immediately after event number 4 by dashed line 76. Dec 5, 2012. Lexar Industrial MRV090 Worm Gear 40 1 56c Speed Reducer. It also makes it possible to disengage the turbine part of the gear, to brake that turbine part and then to reengage the gear parts in their new relative positions. The fuel rack automatically operates to maintain the RPM at the idle speed of the engine which would otherwise be reduced as a result of the load provided by the partial engagement of the astern clutch. RECORD TO CORRECT THE CONVEYING PARTIES ON A SECURITY AGREEMENT DOCUMENT PREVIOUSLY RECORDED ON REEL 017971 FRAME 0375;ASSIGNORS:REXNORD INDUSTRIES, LLC F/K/A ADDAX, INC.; CLARKSON INDUSTRIES, INC./HIGHFIELD MANUFACTURING COMPANY; PT COMPONENTS, INC.; REXNORD CORPORATION; REXNORD INDUSTRIES, INC.; REXNORD NORTH AMERICA HOLDINGS, INC.; W.M. This causes the bull gear 36 and propeller shaft 14 to rotate in a direction which results in the forward propulsion of the marine vessel. In addition, this definition shall be used to refer to a clutch which is intended to operate for a predetermined period of time in a condition which is partially engaged. Then, the ahead clutch is again disengaged. Therefore, in known marine vessel transmissions, any slippage that may occur between the transfer gears and their respective drive shafts only occurs temporarily during the change in status from complete disengagement to complete engagement or, vice versa. A marine reduction gearbox, or transmission, is provided with variably engageable clutches connected in torque transmitting relation between a prime mover and a propeller shaft. Through this connection, the bull gear 36 and the propeller shaft 14 are caused to rotate in a direction which causes the propeller shaft to move in a reverse or astern direction. The term transmission properly refers to the whole drivetrain, including clutch, gearbox, prop . It also comprises an ahead transfer gear and an astern transfer gear which are connected in tooth mesh relation with each other. The forward transfer gear 20 is connected in torque transmitting association with a forward drive shaft 28 through a variable engageable clutch 30. A forward, or ahead, transfer gear 20 and a reverse, or astern, transfer gear 22 are associated in torque transmitting relation with the input shaft 16. It is very important to note that the empirical information illustrated in FIG. Would they work if I connected them in reverse? Since the idle speed indicated by dashed line 114 is higher than the desired speed indicated by dashed line 116, the ahead clutch must be disengaged to slow the propeller speed. Illustration from Army Service Corps Training on Mechanical Transport, (1911), Fig. The differential reduction produces a gear ratio of about 4:1 between the engine crankshaft and the wheels. It should be understood that known marine vessel transmissions, or gearboxes, incorporate transfer gears, forward and reverse drive shafts, ahead and reverse pinion gears, bull gears, brakes and propeller shafts. A helical gear box can be used with a hold back fitted in it to prevent from reverse rotation of the belt in case of power failure. Generally speaking the reduction gear is of the proven single-input single-output design with built-in clutch and thrust block. The reverse pinion gear 32 and the forward pinion gear 34 are not connected in tooth mesh relation with each other. A transmission is connected between the prime mover and an output shaft which is connected to the load. A rearward transmission is also connected between the forward transmission and the output shaft for reversing the direction in which the latter is driven while still taking the drive in the same direction from the unidirectional prime mover. U.S. Pat. A forward pinion gear is provided and connected in torque transmitting relation with the forward shaft while a reverse pinion gear is connected in torque transmitting relation with the reverse shaft. 2 identified by reference numeral 44 represents the pneumatic pressure provided to the astern clutch. 1 shows a schematic illustration of the present invention connected in torque transmitting relation between a prime mover and a propeller shaft. Eventually, the astern clutch is fully engaged, prior to event number 5, and the engine RPM matches the propeller RPM, as a percentage of their respective maximum speeds. This ability is significantly advantageous in certain applications where the back torque experienced by the propeller shaft could cause tooth separation within the gear train if the engine is set at its idle speed. 5 illustrates the typical procedure required to perform this maneuver with known gearboxes made in accordance with the prior art. 4, the control system continually monitors the passage of time to determine whether or not the required time has elapsed to indicate that the marine vessel has slowed to an acceptable speed to engage the astern clutch with the brake disengaged. How to reduce VFO sensitivity to the hand capacitance? Reverse Gear. The transmission oil is circulated and cooled through a separate external oil cooler core, which is in turn cooled by the engine water. Animation: Planetary gear with fixed carrier Fixed sun gear. This creates a load on the engine that causes the fuel rack to increase the power output of the engine even though the propeller is inhibited by the brake from rotating. When the appropriate time has elapsed, the brake is moved to a slip mode and the astern clutch is more fully engaged, at a predetermined rate, from its slip mode, or partially engaged mode, to a fully engaged mode. 3, dashed lines are used to represent the corresponding magnitudes that would have occurred if the same procedures were performed using a gearbox made in accordance with the prior art instead of the present invention.

Found inside – Page 87The devices used to transmit the power developed by a marine engine to the propeller of a vessel are , in general , clutches , reverse gears , reduction ... By specifying a controllable pitch propeller, stalling of the prime mover can possibly be avoided during crash reversal operations by having the engine constantly under a partial load. Purify your mind!'. Asking for help, clarification, or responding to other answers. The control system then continually monitors the engine speed to determine whether or not it has reached a predetermined reduced speed less than maximum RPM, but grater than its idle speed. Gear type is helical gear, which is having an inclined pitch by which chances of the failure of the tooth will be minimum. In a preferred embodiment of the present invention, the marine reduction gearbox comprises an input shaft that is connectible in torque transmitting relation with an engine. No. 2 and line 70 in FIG. A brake is associated with the gearing in order to transmit power and to help absorb the energy of reversal upon reversal of direction of torque. This increase in power output by the engine prepares it for its subsequent connection to the propeller shaft with the brake disengaged. This connecting means typically includes an input shaft connected to the unidirectional prime mover, such as a diesel engine. Jul 30, 2011. 4, the control system continually monitors the passage of time to determine whether or not the required time has elapsed to indicate that the marine vessel has slowed to an acceptable speed to engage the astern clutch with the brake disengaged.

The astern clutch 44 is fully disengaged, the propeller 46 is still and held by the brake 50 which is fully engaged. Car oil pressure gauge flips between 0 and 100%. Found inside – Page 183With the low or reverse band applied (reaction sun gear or ring gear held stationary), the gear set provides a low or reverse gear reduction of 1.82 to 1.0. 6. Jul 22, 2014. Lexar Industrial MRV040 Worm Gear 80 1 56c Speed Reducer. 1 shows a schematic illustration of the present invention connected in torque transmitting relation between a prime mover and a propeller shaft. The propeller speed drops from the engine speed to the desired rotational speed indicated by dashed line 116. By preloading the prime mover with a partial load, the power output of the prime mover is increased and stalling of the prime mover is avoided when it is eventually connected in torque transmitting association with an unbraked propeller shaft. Reduction gear is an arrangement by which an input speed can be lowered for a requirement of slower output speed, with same or more output torque. This and many other torque transmitting techniques are known to those skilled in the art. Mophorn Go Kart Forward Reverse Gear Box 10T #40/41 12T #35 Go Karts Accessories TAV2 30 40 41 For 2HP-7HP Engine, Transmission Local Honor, 3 Shift Modes, ONLY Works with 30 Series Torque Converter 4.4 out of 5 stars 80 Typically, an input shaft of a marine reduction gearbox is connectible to the prime mover and is also connected to forward and reverse transfer gears. Beginning immediately prior to event number 4, the astern clutch 44 is commanded to be engaged. A gear train is a mechanical system formed by mounting gears on a frame so the teeth of the gears engage. This is illustrated by functional block 104. In order to achieve an average speed equal to that indicated by dashed line 116, the ahead clutch must be repeatedly engaged and disengaged in an attempt to maintain this average speed. However, it should be understood that between event number 3 and event number 4 the engine speed 40 is at its idle RPM and the fuel rack 42 is constant at a position to achieve that idle RPM of the engine. So your boat's marine gear has three functions that are completely different from your car's transmission. In this manner, torque is transmitted from the prime mover 12 through the input shaft 16 and forward transfer gear 20 to the forward drive shaft 28 and forward pinion gear 34. The transmission includes a prime mover such as a gas turbine engine or a diesel engine. Therefore, while the pneumatic pressure represented by line 44 shows a decrease immediately after event number 4, this pressure decrease does not represent a decrease in clutch pressure, or slippage. 17+ TURBO GEAR REDUCTION KIT INCLUDES: 1 - 67T LOW GEAR.

CREDIT SUISSE, AS ADMINISTRATIVE AGENT, NEW YORK, Free format text: Was: $37.04. This causes the fuel rack 79 of the control system to increase the fuel flow to the engine and, as a result, increase its power output to a magnitude greater than that which it would normally provide if the engine was not loaded but, instead, completely disconnected from both the forward and astern gears of the marine reduction gearbox as known in the prior art. It is also important to note that, immediately after event number 4, as the astern clutch begins to move from disengagement to engagement and the brake is released, the propeller 46 experiences a temporary return to forward rotation because of the windmilling effect caused by the forward motion of the marine vessel through the water and the disengagement of the brake 50. Gearbox Type 2 stage compound gearbox Gear Type Helical Gear Gear Ratio 9.11 1st stage Reduction Ratio 2.5 2nd stage Reduction Ratio 3.644 Pressure Angle ( β ) 20 degree Helix Angle ( α ) 20 degree Works when I help it by hand. 4,316,722, which issued to Aschauer on Feb. 23, 1982, discloses a propulsion system for a submarine which comprises a low noise level, rapidly reversible propulsion system having a non-reversible adjustable speed prime mover, a reversible drive mechanism driven by the prime mover and a fluid-cooled torque converter and speed reduction apparatus. 2, where the engine is in an unloaded condition at idle speed and suddenly commanded to drive the propeller shaft in a direction opposite to that in which it is being induced by the forward motion of the marine vessel through the water. 2 are intended to represent percentages of full speed or full engagements rather than specific magnitudes. Instead, it should be clearly understood that the astern clutch experiences a constant increase in engagement between a time immediately prior to event number 4 and the occurrence of event number 5. A second significant advantage of the present invention is that it permits the marine vessel to be operated at speeds which are less than those that would normally occur if the engine of the marine vessel is operated at idle speed and the propeller shaft is connected in full torque transmission relation with the engine.
