摘要

#CMT# #/CMT# The radial cage (1) has axial webs (4) that are connected at outer diameters of side rings (2,3). Several pockets (5) are provided between axial webs for receiving cylindrical rolling elements (6). The rolling elements with inclined surfaces (7-10) are formed on lower edges of the side portions and upper edges (11,12) of the axial central portion (4e). The profile rollers, side rings and central portions are arranged, such that material thicknesses of rollers are smaller than the thickness of the side portions (4a,4b) of axial webs. #CMT# : #/CMT# The side rings are connected to side portions in a state extending from intermediate portions (4c,4d) and central portion in longitudinal cage axis (AK). #CMT#USE : #/CMT# Radial cage e.g. needle bearing cage for cylindrical rolling elements used for planetary gear bearing in planetary gears of automatic transmissions in motor cars. #CMT#ADVANTAGE : #/CMT# The damage of radial cage is avoided reliably, since bar ruptures of axial webs occur at high speeds. The manufacturing cost of radial cage is reduced. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawings show the cross-sectional views of radial cage. 1 : Radial cage 2,3 : Side rings 4 : Axial webs 4a,4b : Side portions 4c,4d : Intermediate portions 4e : Central portion 5 : Pockets 6 : Rolling elements 7-10 : Inclined surfaces 11,12 : Upper edges AK : Longitudinal cage axis.
