Embodiment 1
[0031] The embodiment of the present invention provides an overrunning clutch, which is suitable for use in marine gear transmission systems. The system uses multiple hydraulic motors to drive multiple pinion gears, and then these pinion gears drive the same large gear synchronously. See figure 1 , the overrunning clutch includes:
[0032] A shaft sleeve 1, a positioning pin (not marked in the drawings), a plurality of one-way clutches 2 sleeved on the shaft sleeve 1, and a limit mechanism 3 for preventing the one-way clutches 2 from axially moving on the shaft sleeve 1. One end of the sleeve 1 is provided with a radially outwardly extending boss 11 .
[0033] see figure 2 Each one-way clutch 2 includes: a one-way clutch body 21 and a wetting mechanism 22 for realizing one-way transmission between the one-way clutch 2 and the bushing 1, and the wetting mechanism 22 is installed on the one-way clutch body 21 .
[0034] The one-way clutch body 21 is provided with at least on...
Embodiment 2
[0071] An embodiment of the present invention provides a driving device, see Figure 8 , the driving device includes: a hydraulic motor 4, an overrunning clutch 5 as described in Embodiment 1, and a pinion 6, the overrunning clutch 5 is installed on the output shaft 41 of the hydraulic motor 4, and the pinion 6 is installed on the overrunning clutch 5 .
[0072] Below with reference to the accompanying drawings, the assembly process of an overrunning clutch, pinion 6 and hydraulic motor 4 will be briefly described.
[0073] 1. Assembly process of overrunning clutch 5 and pinion 6.
[0074] see Figure 9, firstly, the wedging mechanism 22 is installed on the one-way clutch body 21, specifically, in this embodiment, the pressing element 222 (for example: a compression spring) is installed in the deep groove part of the groove 212 and installed in the The rollers 221 in the shallow grooves of the grooves 212 are in contact with each other. When the rollers 221 are installed, t...

Abstract
The invention discloses an overrunning clutch and a driving device, belonging to the technical field of mechanical transmission devices. The overrunning clutch includes: a shaft sleeve, a positioning pin, a plurality of one-way clutches, and a limit mechanism, and the one-way clutch includes a one-way clutch body and a wedge for realizing one-way transmission between the one-way clutch and the shaft sleeve. The one-way clutch body is provided with at least one positioning pin hole for cooperating with the positioning pin, the axis direction of the positioning pin hole is parallel to the axial direction of the one-way clutch body, and the positioning pin hole is a through hole. The present invention forms an overrunning clutch by a shaft sleeve, a positioning pin, a plurality of one-way clutches, and a limit mechanism. When the overrunning clutch is applied in a gear transmission system, there is no need to add additional flow servo for the hydraulic oil driving these hydraulic motors. The control device can not only save the manufacturing cost of the gear transmission system, but also simplify the structure of the gear transmission system and increase the working stability of the gear transmission system.
Description
technical field [0001] The invention relates to the technical field of mechanical transmission devices, in particular to an overrunning clutch and a driving device. Background technique [0002] In the existing marine gear transmission system, multiple hydraulic motors are usually used to drive multiple pinion gears, and then these pinion gears synchronously drive the same large gear to realize high torque transmission of the gear transmission system. [0003] During the driving process, if the speed of a small gear is too fast, it will drive the speed of the large gear to be too fast, and then the large gear will drive the relatively slow small gears to rotate faster, so that the hydraulic motors driving these small gears cannot reach the maximum speed. Therefore, these hydraulic motors are required to have a high synchronous operation function, and a servo control device is required to servo control the flow of hydraulic oil driving these hydraulic motors. Increases the m...
