Problems solved by technology

Therefore, its inherent disadvantages have not been overcome
For example, the precision and process requirements of manufacturing and assembly are too high, the coaxiality requirements are too strict, the cost is too high, the axial movement of the moving ring is relatively large, the axial and radial dimensions of the core structure and the exclusive space are large, which is not easy Miniaturization, resulting in too narrow application range (mainly used in a small number of transmission shafts such as ships and large generator sets), and poor versatility
Moreover, the he...

Embodiment 1

[0040] Embodiment 1: Wheel-shaft transmission type one-way overrunning clutch C1 with packaging form 1

[0041] see figure 1 , the fixed ring 50 of the overrunning clutch C1 and the supporting shell 230 are fastened into one body by screws 218, and the two are axially fixed on the second rotating member 208 by means of two bearings 224, so that the force transmission fitting mechanism M1 and the lead-out mechanism M2 , the introduction mechanism M3 and the fixed-point actuation mechanism M4 are encapsulated, and can rotate around the axis 200 individually or integrally.

[0042] The force transmission fitting mechanism M1 includes a fixed ring 50 and a moving ring 70 that are fitted axially relative to each other, see figure 1 ~ Figure 3. The force transmission teeth 72 uniformly distributed on the circumference of the moving ring 70 preferably have a force transmission tooth flank 74 parallel to the axis 200 , and the other tooth flank is an auxiliary lead-out tooth flank 1...

Embodiment 2

[0064] Embodiment 2: Wheel-shaft transmission type one-way overrunning clutch C2 with package form 2

[0065] control figure 1 , 4 , the overrunning clutch C2 is a deformation of the overrunning clutch C1, and it radially outwards the moving ring 70 and the second rotating member 208 of the latter, adding a pawl holding mechanism M8, a damping mechanism M9 and a rigid integral body with the fixed ring 50. The first rotating member 206 .

[0066] see Figure 4 , the damping mechanism M9 includes a damping through hole parallel to the axis 200 on the second rotating member 208, a cylindrical damping member 226 movably embedded in it, a spring and a threaded plug assembly 228, and a middle section formed in the damping through hole Corresponding to the breathing hole for damping oil or gas in and out of the spring part. Apparently, this structure is more suitable for the solution where the spline tooth pair has a lead-in function.

[0067] Different from the bidirectional da...

Embodiment 3

[0077] Embodiment 3: Shaft-shaft transmission type two-way overrunning clutch C3 without encapsulation

[0078] see figure 1 , 8 The two-way overrunning clutch C3 is essentially an organic superposition of two one-way overrunning clutches C1 with opposite working directions (the bearing 224 and the supporting shell 230 are removed), and an actuation for causing the fixed-point actuation mechanism M4a or M4b to fail is added. The selection mechanism M5, the reversing mechanism M6 used to specify the working rotation direction of the clutch, the reversing drive mechanism M7 that controls the mechanism, and the optional pawl holding mechanism M8 and a small number of auxiliary components.

[0079] In addition to the fact that the force transmission teeth 52 and 72 have two force transmission tooth flanks 54 and 74 parallel to the axis 200 for the purpose of transmitting torque in the two circumferential directions, and the circumferential degree of freedom in the fitted state sh...

Abstract

The invention relates to a guided jaw overrunning clutch, which is characterized in that: the guided jaw overrunning clutch is provided with a rotating lead-in mechanism, a rotating lead-out mechanismand a fixed-point actuating mechanism controlling accurate motions of the lead-in mechanism; lead-out and lead-in motions of a shifting ring relative to a fixed ring are carried out along a fixed spiral track, are accurate in the axial direction and the circumferential direction, are not influenced by the rotate speed and the abrasion, have no need of assistance of enforcing power, and are spontaneously completed in the relative rotation; moreover, the working direction of the clutch can be changed and the special fixed-point actuating mechanism loses effectiveness by simply changing and locking a relative position of a guiding ring, so that the jaw overrunning clutch becomes a one-way or bidirectional overrunning clutch, a sliding device, a coupling or a simple clutch. The guided jaw overrunning clutch has the advantages of large transitive torque, high rotate speed, high reliability, no collision, impact resistance, small or zero no-load torque, long service life, low cost and smallvolume. Compared with all prior art and products comprising an SSS synchronizing clutch, the guided jaw overrunning clutch has the quality advantage except the field of scale division.

Description

technical field [0001] The present invention relates to a clutch device in the field of mechanical transmission, and other transmission devices such as jaw differentials including such a clutch device, especially but not only to a clutch device with the functions of transmitting torque and rotating overrun Jag type overrunning clutch. Background technique [0002] As the main / flow type in the prior art, the friction type overrunning clutch has the disadvantages of low carrying capacity, poor reliability, low transmission efficiency, difficult processing and assembly, high cost, easy wear, and small application range ("Development Status of Overrunning Clutch and Trends", Zhang Jizheng et al., The Third International Conference on the History of Mechanical Technology between China and Japan, Kunming, 2002, 398~403). The embedded, although has considerable potential to overcome the above shortcomings, but because of collisions, collision noises and inherent knowledge in the i...
