Problems solved by technology
[0002] At present, the existing overrunning clutches include roller overrunning clutches, ratchet overrunning clutches and sprag overrunning clutches. Roller overrunning clutches and pawl overrunning clutches have been reversible, but their carrying 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 is that it can only achieve relative overrunning in one direction, and cannot meet the requirements 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
In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem

Embodiment Construction
[0011] 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 method, Structure, characteristic and effect thereof are as follows in detail.
[0012] see figure 1 with figure 2 the law, figure 1 It is a schematic diagram of the structure of the reversible sprag type overrunning clutch with grooves on the inner ring of the application, figure 2 for figure 1 cutaway view. The reversible sprag type overrunning clutch with grooved inner ring includes an outer ring 1, an inner ring 2, a plurality of sprags 3, a spring 4 and a shift fork 5. In the present invention, the spring 4 is a tension spring, a compression spring or a leaf spring.
[0013] In one embodiment of the present invention, the inner ring 2 is provided with arc-shaped grooves distributed along the circumferential direction. Between the outer ring 1 and the inner ring 2, a spring 4 is arranged be...

The invention relates to a reversible wedge-type overrunning clutch with grooves in an inner ring. The reversible wedge-type overrunning clutch comprises an outer ring, the inner ring, a plurality of wedges, a spring and a shift fork, wherein arc-shaped grooves are formed in the inner ring and distributed along the peripheral direction. According to the reversible wedge-type overrunning clutch, the inner ring is provided with the arc-shaped grooves distributed along the peripheral direction, mutual conversion of overrunning relationship between the outer ring and the inner ring is achieved through manipulation of the shift fork, mutual locking between the outer ring and the inner ring also can be achieved, and a coupler which transmits power in a bidirectional mode is formed.
Description
technical field [0001] The invention relates to a nodal overrunning clutch, in particular to a reversible sprag type overrunning clutch with grooves on the inner ring. Background technique [0002] Existing overrunning clutches include roller type overrunning clutches, ratchet type overrunning clutches and sprag type overrunning clutches at present, and roller type and ratchet type overrunning clutches have reversible types, but the carrying capacity is relatively low. 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 it 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 ov...
