Many different types of marine transmissions, or reverse reduction gear boxes, are available to perform the functions described above. One of the brake valves is piloted by an accumulated speed pressure signal indicating an ahead speed greater than a predetermined minimum and the other valve is piloted by the throttle signal commanding astern direction. In a most preferred embodiment of the present invention, the brake is connected in rotation inhibiting relation with the reverse shaft and reverse pinion gear and is associated in coaxial relationship with those components. In other words, if the idle speed of a prime mover is hypothetically 35% of its maximum speed and the desired rotational speed of the propeller shaft is less than 35% of its maximum speed, significant difficulty is experienced in maintaining the desired speed of the vessel. 6 shows a representation of a technique for operating a marine vessel at speeds below the idle RPM of its prime mover utilizing the concepts of the present invention. 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. It should be clearly understood that the slope of line 62 is not meant to be representative of any preferred length of time but, instead, is used to indicate the compatibility of a variably engageable clutch with this type of procedure. 6 can be performed with the engine speed set at its idle speed, the present invention also permits the maneuver to be performed with the engine speed set at a magnitude that is above its idle speed. The forward transfer gear 20 is connected in torque transmitting association with a forward drive shaft 28 through a variable engageable clutch 30. 2,749,776, which issued to Fischer et al on June 12, 1956, discloses a reversing gear and a drive control that is particularly adapted for use with a marine propulsion unit. Most mechanical gear box designs can accommodate 4 to 6 different 'gears'. 33% lower low gear and 7% lower high gear for Rock Crawling on larger diameter tires such as 32 and Up. It should therefore be understood that the present invention, with its variably engageable clutch, permits the engine to be partially connected in torque transmitting relation to a fully braked and completely still propeller shaft immediately after the brake is completely engaged during a crash reversal procedure. Found inside – Page 1187TABLE 41–1 LAWS OF SIMPLE PLANETARY GEAR OPERATION Sun Gear Carrier Ring Gear Speed Torque ... Output Held Input Increase Reduction Reverse of input 7. If vibratory torque exists in the system, the slight drag provided by the brake in addition to the slight drag provided by the astern clutch, even when both the brake and the astern clutch are fully disengaged, provide a dampening effect which reduces the noise and stresses that could otherwise result from the vibratory torque while the marine vessel is operated in the ahead direction which is its most common mode of operation. During sea trials, the appropriate time delay could be determined and used instead of measuring the RPM of the engine as indicated by block 82 in FIG. These actions are represented by functional blocks 100 and 102. BQLZR High Torque 12v DC 25 RPM Gear-box Stabilivolt Electric Motor. The propulsion system comprises a relatively large engine, or prime mover, and a power transmission which includes an output shaft for driving the propeller. This condition, which could lead to noisy operation and damage to the components of the gearbox, can be reduced or eliminated if the engine is operated at a magnitude above its idle speed. As described in significant detail above, the primary difference between the present invention and marine reduction gearboxes made in accordance with the prior art is that the present invention provides one or more variably engageable clutches in torque transmitting relation between the prime mover and the propeller shaft. 2 and line 70 in FIG. The control described in this patent engages the brake when the throttle lever is moved from an ahead to an astern direction at medium or high forward speeds. 3,363,732, which issued to Nakamura et al on Jan. 16, 1968, discloses a forward and reverse transmission with a brake for a prime mover. A reverse motor, reverse motor solenoid, reverse control solenoid, a reverse control module, a 150 amp manual reset circuit breaker, and a reverse hand switch.

Actually, the gain in reverse ... We offer a complete line of standard Vertical Offset Gear Drives which can be used as speed reducers or speed . In FIG. A second reason to use a worm gear is the inability to reverse the direction of power. It should be clearly understood that the slope of line 62 is not meant to be representative of any preferred length of time but, instead, is used to indicate the compatibility of a variably engageable clutch with this type of procedure. ;ASSIGNOR:KRIESELS, PETER C.;REEL/FRAME:005558/0648, MERRILL LYNCH CAPITAL CORPORATION, NEW YORK, SECURITY AGREEMENT;ASSIGNOR:REXNORD CORPORATION;REEL/FRAME:017971/0375, MERRILL LYNCH CAPITAL CORPORATION, AS ADMINISTRATI, 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. Would they work if I connected them in reverse? These transfer gears continually rotate in opposite directions during operation and are driven by the prime mover. Torque and Speed of a DC Motor with Pulleys and Wheels, Functionally Matching Gears (teeth count) in Planetary Gearbox. The ahead clutch 48 is completely engaged prior to event 1 and the propeller speed 46 is operating in an ahead direction corresponding proportionally to the engine RPM 40. Parsons gearboxes have been in widespread use since the 1920s. 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. Today at 14:52 I will be exactly 1 billion seconds old. 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. Boston Gear F718-40-b5-g Speed Reducer C-face 56c 40 1. 1 shows a schematic illustration of the present invention connected in torque transmitting relation between a prime mover and a propeller shaft. They are either manual, with a gear lever mounted on the box, or remotely operated. 28BYJ-48s cannot run at 60 RPM shaft speed, try steps per rev = 32 and rpm = 640, that should give about 10 RPM shaft speed, remember, the 28BYJ-48 has a 32 step motor and 64 to 1 gear reduction. In this case the carrier serves as the gearbox output. The frequency converted is connected electrically between the generator and motor during starting and reversal procedures when the motor would normally have to operate as an induction motor. 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. U.S. Pat. 3 represents the actual degree of engagement of the astern clutch plates. When the astern clutch increases its degree of engagement, with the brake released, the engine RPM drops further as the time approaches event number 5. Compare this product Remove from comparison tool. In other words, the virtually simultaneous operation of the initial astern clutch engagement command and the brake disengagement command, at event number 4, rapidly places the engine in a condition where it must attempt to increase the speed of the propeller shaft from still to reverse at a time immediately after the engine is operating at its idle speed with no load, such as that time illustrated between event number 3 and event number 4. Alibaba.com offers 2,578 reverse reduction gear products. With continued reference to FIG. 2 represents the pneumatic actuation pressure used to activate the astern clutch, line 70 of FIG. It is also a great option for those who do a lot of plowing. Theoretically if a lever is long enough you can "turn" anything. This transfers torque from the prime mover 12 through the input shaft 16 to the reverse transfer gear 22. The best is to do mod#3, as this will give you 25% lower ratio, and 25% lower engine braking, this is great for those larger tire applications or mudding, and will not hurt top speed at all!!!! BERG, INC., REXNORD INTERNATIONAL INC., REXNORD PUERTO RICO INC., THE FALK SERVICE CORPORATION, Assigned to CREDIT SUISSE, AS ADMINISTRATIVE AGENT, Assignors: MERRILL LYNCH CAPITAL CORPORATION. This preloading of the prime mover while at idle speed increases the power output of the prime mover and prepares it for an eventual connection to a rotatable propeller shaft with the brake disengaged or partially disengaged. 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. The planetary transmission is provided with free-floating compound planetary gear elements in which two of the planet gears of each planetary element mesh with a pair of gears coaxial with the transmission axis. The ahead clutch 48 is completely engaged prior to event 1 and the propeller speed 46 is operating in an ahead direction corresponding proportionally to the engine RPM 40.

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. At event number 1, the ahead clutch is commanded to a partially engaged status equivalent to the percentage of the speed of the engine which is desired on the part of the propeller shaft. It includes two sun wheels, two sets of planetary gear wheels, two planetary gear wheel carriers and two external ring wheels. The control system immediately commands the engine to reduce its speed to its idle speed, as shown by functional block 80. As this rotational speed of the propeller falls below dashed line 116 and the marine vessel slows to a speed below that which is desired, the ahead clutch is reengaged as indicated by line 110 at event number 2. This is illustrated by functional block 104. 4,252,034, which issued to DeBruyne on Feb. 24, 1981, describes a free-floating planetary transmission with a reversible output.
