ROLLING BEARING HAVING OPTIMIZED OUTER RACE

摘要

The invention relates to a rolling bearing (1), comprising rolling elements (4) and an outer race (2), wherein an outer shell (12a, 12b) of the outer race (2) comprises two circumferential grooves (10, 11) axially spaced at least by the amount of the axial extent of the rolling elements (4), and wherein a first part of the outer shell (12b) axially between the two grooves (10, 11) is radially retracted relative to a second part of the outer shell (12b) axially outside of the grooves (10, 11), and wherein the outer race comprises a substantially constant thickness in the area of the first part of the outer shell (12a). In order to provide a simple rolling bearing that is inexpensive to produce and fits in a standard installation space, the invention proposes that the ratio for each groove between a radial wall thickness (B) of said groove and an axial wall thickness (A) of said groove is in the range from 0.5 to 1.5, wherein the radial wall thickness (B) corresponds to the smallest radial wall thickness of the outer race, and wherein the axial wall thickness (A) corresponds to the smallest axial distance of the groove from an adjacent end face (14, 15) of the outer race.
