Abstract
A gear mechanism or motor includes a shaft, and output rotary bodies which are in engagement therewith. The bodies interact with the shaft in the radial direction, by bearing against the shaft, and interact in the axial direction of the shaft with an upper guideway body which can move in the axial direction and is loaded toward the bodies. An interaction region of the shaft has a circular cross section. A guideway of the guideway body is structured in terms of its height over its periphery.
Claims44
A gear mechanism comprising:
- a gear-mechanism shaft, an upper guideway body having a guideway, and output rotary bodies which are in engagement with the gear-mechanism shaft, the output rotary bodies interact with the gear-mechanism shaft in the radial direction, by bearing against the gear-mechanism shaft, and interact in the axial direction of the gear-mechanism shaft with the upper guideway body which can move in the axial direction and is loaded toward the output rotary bodies, an interaction region of the gear-mechanism shaft having a circular cross section, and the guideway of the upper guideway body is structured in terms of its height over its periphery in relation to a circumferential circular orbit of the output rotary bodies, so that a to and fro movement of the upper guideway body in the direction of the gear mechanism shaft results.
A motor, comprising:
- an output shaft, the output shaft having a radial bearing arrangement, the bearing arrangement including an upper guideway body having a guideway, and output rotary bodies which interact directly with the output shaft, in that the output rotary bodies are circular in cross section, and the output shaft is circular in cross section in the interaction region, and in that the output rotary bodies interact with the upper guideway body, the guideway of the upper guideway body is structured in terms of its height over its periphery in relation to a circumferential circular orbit of the output rotary bodies, so that a to and fro movement of the upper guideway body in direction of the output shaft results.
