Roller type bidirectional overrunning clutch

Abstract

The invention discloses a roller type bidirectional overrunning clutch, which comprises an outer ring (1), an inner ring (2), first rollers (3), second rollers (4), a first wavelike belt (5), a second wavelike belt (6), a first hole check ring (7) and a second hole check ring (8), wherein the inner diameter end face of the outer ring is that two sections of symmetric reverse oblique lines are connected to define a similar convex surface through a transition circular arc; the outer diameter end face of the inner ring is that two sections of symmetric reverse oblique lines are connected to define a similar concave surface through a transition circular arc; the flange end of the outer ring is opposite to the flange end of the inner ring; lined first rollers and lined second rollers are assembled between the outer ring and the inner ring and are isolated at an equal distance through the first wavelike belt and the second wavelike belt; and the first hole check ring and the second hole check ring are configured in a clamping groove which is formed in the outer ring respectively. According to the roller type bidirectional overrunning clutch, no control mechanism exists, the space is saved, more first rollers and second rollers can be arranged, the torque transfer capacity is superior to that of the normal overrunning clutch, and the roller type bidirectional overrunning clutch has the advantages of high load, long life and easiness and convenience in control.

Description

technical field [0001] The invention belongs to the technical field of overrunning clutches, in particular to a roller type two-way overrunning clutch. Background technique [0002] Ordinary overrunning clutches can only achieve the function of one-way transmission of torque, that is, the engagement of the inner ring and the outer ring is realized in one direction of rotation, and the mutual disengagement of the inner ring and the outer ring is realized in the other direction of rotation. It is called overrunning, which means that ordinary overrunning clutches can only achieve one-way engagement and one-way overrunning. [0003] figure 1 It is a schematic structural diagram of a roller type two-way overrunning clutch with a claw. The roller type two-way overrunning clutch with a claw controls two rows of rollers c through the claw e and spring d, and the two rows of rollers are fitted on the outer ring Between a and the inner ring b, one row of rollers realizes forward ove...

AI Technical Summary

Problems solved by technology

[0004] First, when engaging in the same direction and overtaking in the same direction, only one row of rollers in the two rows of rollers can participate in the transmission of torque while the other row of rollers does not transmit torque. The transmission torque capacity of the overrunning clutch;

[0005] Second, the claw controls each roller. To ensure that the effect on each roller is the same will increase the complexity of the structure of the two-way overrunning clutch, and also increase the processing difficulty and matching accuracy of the two-way overrunning clutch;

[0006] Third, when the two-way overrunning clutch runs for a period of time, each roller will wear to a certain extent, making its diameter smaller, resulting in a decrease in the control accuracy of the finger and affecting the service life of the two-way overrunning clutch
