Document Type and Number:
Japanese Patent JP2018132115
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a radial roller bearing in which disengagement of a roller from a pocket of a cage can be suppressed.SOLUTION: A radial roller bearing 1 comprises an outer ring 2 having a pair of rib parts 21, 22 protruding to the radial direction-inside from both ends of a cylindrical body part 20, a plurality of rollers 3, and a cage 4. The cage 4 has a pair of annular parts 41, 42 arranged inside a pair of the rib parts 21, 22, and a plurality of bar parts 43 for connecting a pair of the annular parts 41, 42 in an axial direction. The plurality of rollers 3 are accommodated respectively between a plurality of the bar parts 43. The bar parts 43 have heavy-walled parts 430 thicker than a pair of the annular parts 41, 42 in the radial direction, and a pair of connecting parts 431, 432 provided respectively between the heavy-walled parts 430 and a pair of the annular parts 41, 42. The radial direction-rigidity of a pair of the connecting parts 431, 432 is lower than those of the heavy-walled parts 430, and an outside diameter Dof the cage 4 in the heavy-walled parts 430 is larger than an outside diameter Dof the cage 4 in a pair of the annular parts 41, 42.SELECTED DRAWING: Figure 4
