Cage of a rolling bearing, such a cage comprehensive rolling bearing and such a rolling bearing comprehensive apparatus

摘要

The invention relates to a cage (10) of a rolling bearing, the cage (10) comprising: an annular shoulder (20) centered on a central axis (X10) and measured with respect to the central axis (X10) has a constant radial thickness (T20); an axial portion (30) extending from the shoulder (20) substantially parallel to the central axis (X10); and recesses (40) bounded by the shoulder (20) and the axial section (30) for receiving rolling elements (4) of the roller bearing (1); wherein the axial portion (30) has an axial length greater than half the inner diameter of the recesses (40), and an outer diameter (D30) smaller than the outer diameter (D20) of the shoulder (20) and between one first value equal to the pitch circle diameter of the cage (10) minus half the radial thickness (T20) of the shoulder (20) and a second value equal to the pitch circle diameter of the cage (10) plus half the radial thickness (T20) of the cage Paragraph (20) is; wherein the recesses (40) are spaced about the central axis (X10) according to respective values of angular intervals (α1-α8) at least partially different from one another. The invention further relates to a rolling bearing comprising such a cage (10) and to an apparatus comprising such a rolling bearing.
