Abstract

796,670. Ball bearings. STURMEY ARCHER GEARS, Ltd. Dec. 5, 1956 [Dec. 6, 1955], No. 34902/55. Class 12 (1). In a freewheel sprocket comprising an outer ring 22, carrying teeth 23, mounted on an inner ring 10 by means of a ballbearing 21, the inner race of the ball bearing is in two parts, one, 20, of which is fixed and the other, 19, axially movable and resiliently loaded towards the fixed part. The part 20 is screwed on to the inner ring 10 and the part 19 is slidably mounted on a cylindrical surface 18 of the ring 10. Springs 16 disposed in housings 15 act on the part 19. Pawls 14 and ratchet teeth 24 ensure unidirectional relative rotation of the rings 10, 12. In a modification, the part 20 is made integral with the inner ring 10 and the portion carrying the springs and pawls is screwed on to the ring 10.
