Abstract
The invention relates to a revolving gear mechanism with at least two gear wheels which mesh mutually, forming an engagement space, of which one is a revolving gear wheel which is mounted rotatably by means of a bearing on a bolt, and a lateral surface of the bolt forms a bearing surface. According to the invention, at least one axial longitudinal groove is arranged on the lateral surface of the bolt.
Claims19
A revolving gear mechanism comprising:
- (a) at least two gear wheels which mesh mutually, forming an engagement space, said engagement space for accepting a lubricant;
- (b) a bolt, wherein one of said gear wheels is a revolving gear wheel which is rotatably mounted by means of a bearing on said bolt;
- (c) a bearing surface, wherein a lateral surface of said bolt forms said bearing surface;
- and
- (d) at least one axial longitudinal groove is arranged on said lateral surface of said bolt resulting in at least one bolt-mounted gear wheel;
- wherein said at least one bolt-mounted gear wheel further comprises at least one radial bore which connects the engagement space of said at least one mutually meshing gear wheels with a corresponding bearing of said revolving gear wheel.
