A roller bearing cage is made of a bent strip of sheet metal having abutting ends that are connected to one another, the cage being comprised of two end rings and a cage frame surrounding the windows, the windows retaining and guiding the rollers. In order to permit the manufacture of rolling element bearing cages of different reference circle diameters while using only one tool for rolling elements with a specific diameter d, the center distance between adjacent the cage windows in the circumferential direction is .pi.d/2.

The invention concerns a roller bearing for performing swivel motions including a mechanism for synchronously guiding the roller bearing cage, including a roller bearing cage having a journal with a rotatable pinion gear flexibly and elastically mounted thereon in the direction of the circumference of the cage by a crosspiece, the pinion gear having teeth which mesh with at least one set of teeth on the bearing parts of the roller bearing. Stops are provided to limit the motion of the pinion gear.

A cage for ball bearings consists of two side rings connected together by webs, and having ball pockets with ball pockets having curved partial surfaces inside and outside of the pitch circle and displaced from one another in the axial direction. In this arrangement the rubbing between the walls of the cage pockets and the balls is very small and free space is provided for receiving a lubricant. The pocket walls of the cage sections lying in the region of one or the other of the side rings has several radially-overlying zones, with conical surfaces, the conical surfaces being arranged at different inclinations to the bearing axis.

The fixing device is intended for a roller of the type comprising a pulley mounted on a rolling-bearing device comprising a row of rolling elements arranged between a ball race provided on an outer ring integral with the pulley and a ball race provided on an inner ring. The device comprises a screw comprising a cylindrical rod and, at one end of the cylindrical rod, a head provided with a rotary-drive. The device comprises a sleeve arranged on the screw, said sleeve comprising a gripping surface for fixing on the inner ring of the rolling bearing and leaktight seal interacting with a turning part of the roller.

A cage for a ball bearing, especially for an inclined ball bearing, is comprised of two side rings connected together by webs, with one of the side rings being outside of the pitch circle and the other side ring being inside of the pitch circle. Circumferentially resilient axially extending projections are provided extending from one of the side rings toward the other, radially inwardly or outwardly of the pitch circle, and recesses are formed by the webs and projections in the regions of minimum spacing between the balls.
摘要:
A rolling bearing assembly has inner and outer members, rotatable with respect to one another, and defining a pair of races therebetween. Each of these members has a flange-shaped portion for mounting the respective member. A separate row of rolling bearings is provided in each of the races. The outer member is formed with separable ring-shaped portions defining the running surfaces of the two races, the separable portions forming an inwardly directed annular ridge under ajoining faces, so that the rolling elements abut the sides of the ridge. One of the rows of rolling bearings has twice as many rolling elements as the other row.

The outer member is formed with separable ring-shaped portions defining the running surfaces of the two races, the separable portions forming an inwardly directed annular ridge under adjoining faces, so that the rolling elements abut the sides of the ridge. One of the rows of rolling bearings may have a substantially larger number of rolling elements than the other row.
