CAGE OF A ROLLING BEARING, ROLLING BEARING COMPRISING SUCH A CAGE AND APPARATUS COMPRISING SUCH A ROLLING BEARING

摘要

A cage of a rolling bearing, the cage comprising: an annular heel centered on a central axis and having a constant radial thickness measured radially to the central axis; an axial portion extending from the heel substantially parallel to the central axis; and pockets delimited by the heel and the axial portion for receiving rolling elements. The axial portion has an axial length being greater than half the inner diameter of the pockets and an outside diameter being lesser than the outside diameter of the heel and which comprises between a first value equal to the pitch circle diameter of the cage minus half the radial thickness of the heel and a second value equal to the pitch circle diameter of the cage plus half the radial thickness of the heel. The pockets are spaced around the central axis having angular spacings being at least partly different from one another.

1. A cage of a rolling bearing, the cage comprising:
an annular heel centered on a central axis and having a constant radial thickness measured radially to the central axis; an axial portion extending from the heel substantially parallel to the central axis; and pockets delimited by the heel and the axial portion for receiving rolling elements of the rolling bearing; wherein the axial portion has an axial length which is greater than half the inner diameter of the pockets and an outside diameter which is lesser than the outside diameter of the heel and which is comprised between a first value equal to the pitch circle diameter of the cage minus half the radial thickness of the heel and a second value equal to the pitch circle diameter of the cage plus half the radial thickness of the heel; wherein the pockets are spaced around the central axis according to respective values of angular spacings which are at least partly different from one another.
