A gear is described for a spur gear stage without play having a hub (1) and a sprocket (2), which is divided along its axis-normal division plane into two partial sprockets, namely into a hub-fixed sprocket part (3) and a sprocket ring (4) which is mounted so it is coaxially rotatable in relation thereto, and which forms springs (6) sectionally enclosing the hub (1) in the circumferential direction, which are integrally connected at their bases (11) to the sprocket ring (4) and which are supported with their free ends (7) protruding toward the hub (1) on stops (8) of the hub (1). To ensure advantageous spring loads, it is proposed that the sprocket ring (4), which is mounted so it is rotatable on the hub (1), form at least three springs (6), which are arranged rotationally-symmetrically with respect to the sprocket axis, and the stops (8) of the hub (1), which are also arranged rotationally-symmetrically, have approach surfaces (10) for the free ends (7) of the springs (6), which rise radially outward in the circumferential direction toward the bases (11) of the associated springs (6). |
