摘要： A comb-shaped cage for use in a roller bearing having one circular portion axially opposed to the end surface of each of rollers and a plurality of bar portions protruding from one or both axial sides of the circular portion and arranged circumferentially opposed to the rolling surface of each rollers is disclosed. It is designed so as to satisfy the condition 0.2≦(I1′/I3′)≦2.5, wherein I1′ expresses the moment of inertia of area for the circular portion relative to a neutral axis parallel with the longitudinal direction of the bar portion and I3′ expresses the moment of inertia of area for the bar portion relative to a neutral axis parallel with the circumferential direction of the cage. This enables to improve the strength of the cage without lowering the load capacity of the bearing to which the cage is assembled.

摘要： A roller cage for an axial-thrust bearing in a rotating machine has a substantially flat annular body with a first face, a second face, a radially inner surface, a radially outer surface, and a plurality of radially-arrayed substantially rectangular roller pockets with axially oriented sidewalls and endwalls. The cage also has features which provide enhanced flow of lubricant, present within the rotating machine, through the radially arrayed roller pockets during operation of the rotating machine. Rollers are retained within the pockets by a single projection on the sidewall of each pocket at the first face and another single projection on the other sidewall at the second face. Cage design in conjunction with inner and outer race design assures direction of lubricant flow to locations with greatest lubrication and cooling requirements. Because of its simple straight-surface design the cage of the invention is relatively simple to fabricate from polymers by polymer molding processes or from metals by fine flow blanking or ribbon forming and coining techniques.

摘要： Thrust rolling bearing comprising a cage containing and guiding rolling elements. The cage is in two parts, namely a first part having bars defining apertures for the rolling elements and a second part in the form of a ring which has a plane sliding support face. The two parts are interconnected in such manner that they are relatively rotatable. An assembly is disclosed in which the thrust rolling bearing is combined with a coaxial radial needle bearing and the needle ends, or the end of the cage for the needles, bears against the plane sliding support face.

摘要： 1,238,199. Bearings. MOTOREN-UND TURBINEN-UNION MUNCHEN G.m.b.H. 27 Nov., 1968 [29 Nov., 1967], No. 56343/68. Heading F2A. A rolling bearing assembly comprises inner and outer races 1, 2 a cage 4, and means which, during use of the bearing, are rotationally coupled with the cage, other than through the rolling elements 3, to drive the cage. The means comprise the shaft and collar washers 7, 8 attached thereto, and the coupling is hydraulic between the surfaces 7a, 8a and 5, 6 resepetively. The surfaces may be provided with recesses or hydrofoils for maximum torque transmission. The hydraulic medium supplied may be oil or an oil/air mixture. In another embodiment (Fig. 4, not shown), the collar washers are in the form of slinger rings, each provided with a groove and radial passages for supply of the medium to the driving surface.
