Device for coating the groove of a ball bearing with a powder-type solid lubricating material

Abstract

In a device for coating the groove of a ball bearing with a powder-type licating material, in particular molybdenum sulfide, with a polishing component that enters the groove and is movable in relation to the groove, it is proposed, in order to increase the evenness of the coating and at the same time to prevent the area outside the rolling area of the groove from being coated, that the polishing component touch only that area on the groove over which the balls of the ball bearings roll, and that a feed device for the powder-type solid lubricant be provided which applies that lubricant to the polishing component outside the area where the polishing component touches the groove, in an area of the polishing component which comes into contact with the groove during relative movement between the polishing component and the groove.

Dependencies are inferred from the claim text.
