摘要： A bearing type overrunning clutch includes an outer ring (1) and an inner star wheel (2). A plurality of rollers (3) are provided between the outer ring (1) and the inner star wheel (2). A plurality of concave grooves are provided on the outer cylindrical surface of the inner star wheel (2), each of which corresponds to one roller (3) respectively. The clearance between the adjacent rollers (3) is 0 to 0.2 mm. The main characteristic of the invention is to ensure the clearance between the adjacent rollers (3) to be in the range of 0 to 2 mm by increasing the number of rollers in a same space; at the same time, to increase the contact strength by providing the plurality of concave grooves on the outer cylindrical surface of the inner star wheel (2). The invention has advantages of reasonable structure design, simple manufacturing process, high manufacturing accuracy and strong working reliability, etc. The overrunning clutch according to the invention can bear relatively large torque and impact force, and can work for a long time under a circumstance of high speed and heavy load.
