Abstract
A roller body cage, such as a linear bearing cage rail structure having a series of roller bodies which are separated from each other by interposed spacer inserts, and which are prestressed in the longitudinal axial direction of the cage rail through the intermediary of one or more spring elements so as to provide a frictional force between the roller bodies and spacer inserts.
Claims3
In a roller bearing cage for the support of linearly conveyed machine elements, such as machine tool carriages and the like;
- including elongate cage rails;
- and a series of roller bodies being supported between said rails, the improvement comprising:
- spacer means in said cage positioned intermediate each of said roller bodies;
- said spacer means being in contact with said roller bodies, said series of roller bodies and spacer means being positioned so as to generate a frictional force responsive to relative rotation between said spacer means and said roller bodies;
- and at least one prestressed spring means in said cage for exerting a constant compressive spring force on said roller bodies and spacer means in the longitudinal direction of said cage.
