Abstract

In a gear arrangement whose output shaft (5) is rotatably mounted in a gear box (6) and which corotates by means of a dog plate (3) via an axially interposed cushioning disk (2) with a gear (4) driven by a worm shaft (7) and, further, which output shaft is axially supported directly and/or indirectly, via the cushioning disk (2) and the gear (4), by the gear box (6), it is intended to provide, despite design related axial length tolerances, a tolerance play compensation in a manner which is considerably simplified from a production and assembly engineering viewpoint. Towards this end, the elastic cushioning disk (2) is provided with axially projecting spring lips (21 to 23), distributed over its circumference, for the development of a defined preloading pressure upon the components supported by the gear box (6).
