Embodiment Construction

[0019] image 3 The wedge-type controllable overrunning clutch with claws shown is mainly composed of an outer ring 1, wedges 2 and 2a, springs 3 and 3a, a cage 4, a star wheel 5, and a claw 6. The notch has two working surfaces in opposite directions and forms two wedge seams with the outer ring 1; wedges 2 and 2a with the characteristics of the present invention are respectively housed in each wedge seam, and the wedges that push the wedges into contact with the inner cylindrical surface of the outer ring Springs 3 and 3a; in the middle of the two wedges, there is a claw 6 that is limited by an elastic structure and usually presses a wedge that does not contact the outer ring. The elastic structure that limits the claw 6 is connected to the star wheel 5 .

[0020] When the star wheel 5 rotates counterclockwise as the active part, the claw 6 presses the wedge 2a not to contact the outer ring 1 and rotates synchronously with the star wheel 5 under the action of the elastic mec...

Abstract

A wedge type freewheeling clutch apparatus wherein the working surface where the wedge contacts with the inner hole cylinder face of the outer ring of the free wheel device is a portion of the cylinder whose diameter is greater than the operational height of the wedge, the working surface on the wedge witch contacts with the star-wheel is a plane surface. Compared with the prior art wedge type freewheeling clutch apparatus, the advantages of the present invention are better movement consistency, higher reliability, more even load-bearing, greater load-bearing capacity and longer operating life.

Description

technical field [0001] The invention relates to an overrunning clutch, especially a sprag type overrunning clutch and various roller type overrunning clutches. Background technique [0002] At present, the overrunning clutches used in various mechanical transmissions such as mining machinery, machine tools, automobiles, and motorcycles are mainly ratchet pawl type overrunning clutches, roller type overrunning clutches and wedge type one-way overrunning clutches. [0003] The ratchet pawl type overrunning clutch has only one or two ratchet teeth to bear the load when it is working, so the torque that can be transmitted is small, and not any part can transmit torque, and the transmission accuracy is not high, and there is a problem when the overrunning rotation occurs. Loud; use only for low precision and low speed motions. [0004] The existing roller-type overrunning clutches are suitable for higher speeds, and the transmission accuracy is also higher. There is no loud nois...
