Spur gear for force transmission into transmission arrangement, has cutting profile, where base height and curvature radius of cutting profile are lower than respective base height and curvature radius of machining profile

摘要

The gear has a tooth head (16) and an evolvent-tooth system, where the gear is manufactured by pre-machining, hardening and finish-cutting of tooth flanks, and the final tooth form is arranged by combining a pre-machining and finish-cutting profiles. The cutting profile is arranged independent of the machining profile such that the base height of the cutting profile is lower than the base height of the machining profile and the base curvature radius of the cutting profile is larger or smaller than the base curvature radius of the machining profile.
