Embodiment Construction

[0016] like Figure 1~4 The best embodiment of the multi-roller type overrunning clutch shown in the present invention has an inner star wheel type outer ring 1, a cage 3, nine spring plates 2 and nine rollers 4. The inner circular surface 1a of the inner star wheel type outer ring 1 has nine sections of concave arc-shaped wedge surfaces; the cage 3 is tightly fitted in the inner star wheel type outer ring 1, solving such as Figure 5 The conventional three-roller clutch shown needs to drill the oblique hole 60a on the inner star wheel outer ring 60 to press the spring seat 20 and the spring cap 40 as the carrier of the spring 30, so that the number of star wheels 60b cannot be too large, and the torque capacity of the clutch The problem of the limitations of lifting. The cage 3 is a plastic cage. The cage 3 includes two end rings and a beam 3a connecting the two end rings. The rollers 4 are respectively placed in the windows 3b formed by the end rings and the beam 3a, and ar...

Abstract

The invention relates to a multi-roller overrun clutch, in particular to a multi-roller overrun clutch suitable for occasions with small design space and high torsional moment. The clutch comprises at least six rollers, a star wheel type outer ring, a retainer and six spring pieces, wherein the retainer is tightly arranged in the star wheel outer ring; the rollers are placed in each window formed by an end ring and a beam and each concave curved wedge surface in the star wheel type outer ring; one end of the spring piece is provided with an elastic bayonet, and the other end is an arc-shaped end matched with the outer circle surface of each roller; the elastic bayonet of the spring piece is buckled on the beam of the retainer; and the arc-shaped end is matched with the roller and pushes the roller. The invention solves the technical problems that the prior roller clutch has fewer rollers, small transmission torque, complex structure, poor stability and short service life.

Description

technical field [0001] The invention relates to an overrunning clutch, in particular to a multi-roller overrunning clutch suitable for occasions with high rotational speed and high torque requirements. Background technique [0002] Gearboxes or torque converters of automobiles, gearboxes in construction machinery, starters of two-wheeled or three-wheeled motorcycles, and one-way clutches used in transmission or anti-reverse in gearboxes, such as Figure 4 and Figure 5 The three-roller type overrunning clutch shown in , it has three rollers 50 for transmitting torque, supported by the spring cap 40 set on the spring 30, and the outer ring 60 of the inner star wheel type has three oblique holes 60a, the spring seat 20 is tightly fitted in the inclined hole 60a, and the other end of the spring 30 rests on the spring seat 20. In order to prevent the axial displacement of the roller 50, there is also a cover 10 as a foil. It works like Figure 7 As shown: when the inner racewa...
