Bushing-type roller overrunning clutch with a cage for needles or rollers
View Patent ↗A bushing-type roller overrunning clutch comprising at least an inner or an outer ring that comprises clamping ramps adapted to the needles or rollers, said overrunning clutch further comprising a cage for the needles or rollers, as also pressure springs, said cage comprising cage elements that are made in one piece with the inner or outer ring, and a method of making a bushing-type roller overrunning clutch in which the inner or outer ring together with the clamping ramps and at least one border arranged on one side of the clamping ramps is made by deep-drawing, spring-retaining lugs are cut out of the border, and the spring-retaining lugs are bent radially towards the inner or outer ring and the free-standing tabs of the spring-retaining lugs are bent over into the region of the clamping ramps.
1. A sleeve-type/roller freewheel having at least one inner or outer ring which has clamping ramps which are adapted to needles or rollers, having a cage for the needles or rollers and having pressure springs, the cage having cage segments which are produced in one piece with the inner or outer ring, wherein cage elements are configured as spring holding lugs and are attached laterally to the inner or outer ring, wherein the spring holding lugs have exposed tabs which are arranged inside or outside the inner or outer ring in a manner which is adjacent to the clamping ramps.
2. A sleeve-type/roller freewheel of claim 1 wherein the inner or outer ring has an annular shoulder on the side which faces away from the spring holding lugs.
3. A method for producing a sleeve-type/roller freewheel according to claim 1 comprising:
deep drawing the inner or outer ring with the clamping ramps and at least one edge which is arranged on one side of the clamping ramps,
cutting the spring holding lugs out from the edge, and
bending the spring holding lugs radially to the inner or outer ring and exposed tabs of the spring holding lugs are bent over into the region of the clamping ramps.
4. The method for producing a sleeve-type/roller freewheel, cage, of claim 1 comprising:
deep drawing the inner or outer ring which with the clamping ramps as a substantially cup-shaped component,
cutting tabs out from a base edge which is adjacent to the clamping ramps, and
bending the tabs over into the region of the clamping ramps.
5. The method of claim 3 comprising:
forming the edges on the inner or outer ring on the side which lies opposite the edge or the base edge, and
forming the edge over radially as an annular shoulder.
6. The method of claim 3 wherein the inner or outer ring is pressed onto or into a supporting ring.
7. The method of claim 3 wherein a radially inwardly or outwardly protruding collar is formed integrally on the supporting ring, before being pressed with the inner or outer ring.
