Abstract: A face seal assembly includes a first and a second metallic sealing ring having a common center axis, and each including an outer ring surface and an inner ring surface. A non-metallic sealing element is positioned upon the outer ring surface. The metallic sealing ring also includes a sealing face facing an axially outward direction and extending circumferentially around the center axis in a path that varies from parallelism with a plane normal to the center axis. A stiffness relief groove extends inwardly from the inner ring surface and circumferentially around the center axis and forms an annular spring zone of reduced material thickness to compensate for the varying of the path of the sealing face. One machine system application includes a final drive in a ground-engaging machine.

Abstract: A machining center with an abrasive blasting system is disclosed. The machining center includes a bed, a headstock mounted on the bed, and a carriage having a tool post. The machining center also includes an abrasive blasting system for imparting a predefined roughness to a surface of the work piece. The abrasive blasting system includes a reservoir, a pump, a tool and a nozzle. The tool is coupled to a tool post. The tool includes a conduit extending along a length of the tool for receiving the abrasive material therethrough. The nozzle is formed on a tip surface of the tool. The nozzle is configured to communicate to the conduit. The nozzle is adapted to discharge the abrasive material on the surface of the work piece during the machining of the work piece for imparting the predefined roughness on the surface.

Abstract: A method of producing a mechanical face seal, the method including a step of obtaining a cast or wrought substrate part having an inner diameter, outer diameter, and a planar surface. The method may include a rough surface treatment step to form pores, peaks, and valleys on the planar surface of the substrate part. The method may further include a spraying step to supply a spray coating material onto the substrate part to form a protective thermal spray coating layer on the substrate part.
