Problems solved by technology
[0002] There are three types of existing overrunning clutches, roller type, pawl type and wedge type, roller type and pawl type overrunning clutches have been reversible, but the load capacity is low
Although the wedge-type overrunning clutch has a large load-carrying capacity, there has not been a mature reversible structure because the position of the wedge in the circumferential direction is uncertain.
[0003] The main defect of the existing sprag type overrunning clutch: the existing sprag type overrunning clutch can only achieve relative overrunning in one direction, and cannot meet the requirements for the use of mechanical equipment that often changes the overrunning direction
[0004] This shows that above-mentioned existing overrunning clutch obviously still has inconvenience and defect in structure and use, and urgently needs to be further improved

Embodiment Construction
[0015] In order to further explain the technical means and effects adopted by the present invention to achieve the intended purpose of the invention, the specific implementation of a reversible sprag type overrunning clutch with outer ring grooves according to the present invention will be implemented in conjunction with the accompanying drawings and preferred embodiments. Mode, structure, feature and effect thereof are as follows in detail.
[0016] Such as figure 1 , figure 2 As shown in, the present invention relates to a reversible sprag type overrunning clutch with grooves on the outer ring. It consists of outer ring 1, inner ring 2, wedge 3, preload spring 4 and shift fork 5 and other parts.
[0017] The outer ring 1 has arc-shaped grooves distributed along the circumference. The arc at one end of the wedge 3 fits the groove on the outer ring 1. The wedge 3 is placed symmetrically between the outer ring 1 and the inner ring 2. The wedge 3 and the wedge 3 are equipped...

The invention relates to a reversible-wedge-type overrun clutch with an outer ring provided with grooves. The overrun clutch comprises the outer ring (1), an inner ring (2), wedges (3), a pretightening spring (4) and a shifting fork (5), and is characterized in that the outer ring (1) is provided with the arc-shaped grooves (11) distributed along a circle, a circular arc at one end of each wedge (3) is attached to the grooves in the outer ring (1), the wedges (3) are symmetrically arranged between the outer ring (1) and the inner ring (2), the pretightening spring (4) and the shifting fork (5) are arranged between the wedges (3), and the shifting fork (5) and the outer ring (1) rotate synchronously. Mutual conversion of overrun relationship between the outer ring (1) and the inner ring (2) is achieved through operation for the shifting fork (5), and the outer ring (1) and the inner ring (2) can be mutually locked to form a coupler capable of bidirectionally transferring power.
Description
technical field [0001] The invention relates to a clutch, in particular to a reversible sprag type overrunning clutch with grooves on the outer ring. Background technique [0002] Existing overrunning clutch includes three types, roller type, pawl type and wedge type, and roller type and pawl type overrunning clutch have reversible type, but carrying capacity is lower. Although the sprag-type overrunning clutch has a large load-carrying capacity, there has not been a mature reversible structure because the position of the sprag in the circumferential direction is uncertain. [0003] The main defect of the existing sprag type overrunning clutch is that the existing sprag type overrunning clutch can only achieve relative overrunning in one direction, and cannot meet the requirements for use of mechanical equipment that often changes the overrunning direction. [0004] This shows that above-mentioned existing overrunning clutch obviously still has inconvenience and defect in s...
