Two-piece gearwheel for the reduction of tooth engagement noises

摘要

To reduce tooth engagement noises, the invention proposes a gearwheel (2) split radially into two. The inner part is formed by a hub (3) which is seated on a shaft (1) and is connected to a toothed rim (4) by way of splines (19) with radial play. To ensure slight axial displaceability of the toothed rim (4) relative to the hub (3), device elements (6, 7; 15, 16, 23, 24) are provided which act on at least one side of the toothed rim in such a way as to spring-load it and are secured on the hub (3). <IMAGE>
