Insert piece i.e. locking screw, for insertion into threaded hole of electric motor transmission, has shaft-sided contact surface designed for contact of sealing ring and directly passed into outer surface of flange from outside

摘要

The piece has a threaded shaft (1) attached at a flange (2) in an axial direction. A shaft-sided contact surface (21) of the flange is extended in a radial direction and designed for contact of a sealing ring (7). The contact surface is radially and directly passed into an outer surface (23) of the flange from outside. A projection (26) secures the sealing ring against slippage in the axial direction, and is formed at the flange. A sealing ring outer surface (24) is aligned with the outer surface of the flange. The ring is held in a groove between a sleeve section and the shaft. An independent claim is also included for a pressure fluid device comprising a threaded hole forming an access to pressure fluid.
