摘要： The invention relates to an axial cage for cylindrical rolling elements, which is formed substantially of a thin-walled annular disc with a profiled cross section, which is formed by an inner radial rim shaped on the inner edge of the annular disc, by an outer radial rim shaped on the outer edge of the annular disc, and by a center beading connected to the radial rims via axial inner and outer intermediate profile sections. A number of uniformly spaced, rectangular cage pockets are removed from the beading and the adjacent intermediate profile sections, between which cage pockets an identical number of pocket webs are formed connecting the rims with each other, by which the cylindrical rolling elements are held in the cage pockets at a uniform distance to each other and guided in the circumferential direction. The annular disc according to the invention is formed of a through-hardened and tempered, high-alloy spring steel with a maximum hardness of 450 HV, wherein any conventional spring steel with a minimum material thickness of 15% to 25% of the diameter of the rolling elements can be used as the spring steel for the annular disc.

摘要： A refrigeration chiller employs a centrifugal compressor the impellers of which are mounted on a shaft which is itself mounted for rotation using rolling element bearings lubricated only by the refrigerant which constitutes the working fluid of the chiller system. Apparatus is taught for providing liquid refrigerant to (1.) the bearings immediately upon chiller start-up, during chiller operation and during a coastdown period subsequent to shutdown of the chiller and (2.) the drive motor of the chiller's compressor for motor cooling purposes. By use of a variable speed-driven motor to drive the compressor, optimized part load chiller performance is achieved in a chiller which does not require or employ an oil-based lubrication system.

摘要： The present invention provides a hard film which has high wear resistance and excellent peeling resistance and can be prevented from peeling off a base material over a long period of time and a hard film formed body on which the hard film is formed. A hard film (8) has a structure composed of a first mixed layer (8a), consisting mainly of Cr and WC, which is formed directly on a raceway surface (2a) of an inner ring (2) (base material) of a rolling bearing, a second mixed layer (8b), consisting mainly of WC and DLC, which is formed on the first mixed layer (8a), and a surface layer (8c), consisting mainly of DLC, which is formed on the second mixed layer (8b). In the first mixed layer (8a), a content rate of the Cr becomes continuously or stepwise lower and that of the DLC becomes continuously or stepwise higher from a side of the base material toward a side of the second mixed layer (8b). In the second mixed layer (8b), a content rate of the WC becomes continuously or stepwise lower and that of the DLC becomes continuously or stepwise higher from a side of the first mixed layer (8a) toward a side of the surface layer (8c). A content of hydrogen in the second mixed layer (8b) is set to 10 to 45 atomic percent.
