Abstract
A toothed wheel is described for a play-free spur gear set, comprising a hub (1), with a toothed ring (2) supported by the hub (1), which ring is split into two partial rings along a dividing plane normal to an axis, namely into a ring piece (3) fixed to the hub and a ring crown (4) mounted to rotate coaxially relative to the above, and an annular spring (5) enclosing the hub (1) with the circumferentially-opposed ends (6) resting on support webs (7, 8) embodied integrally with both partial rings, overlapping each other in the axial direction and arranged behind each other in the circumferential direction of the toothed ring. In order to avoid any overload of the partial rings produced by way of powder metallurgy and to ensure simple constructional conditions it is proposed that the support web (8) of one partial ring extends through the other partial ring in a through opening (9) with circumferential play and the support web (7) of the partial ring with the through opening (9) forms an assembly stop (10) defining the through opening (9) for the other support web (8).
