ROLLING BEARING

摘要

A rolling bearing wherein the conventional cage is replaced by independent spacers, one per pair of neighbor rolling elements, each spacer is disposed and trapped between neighbor rolling elements, each spacer is supported on its neighbor rolling elements and is preventing them from coming into contact with each other, each spacer comprising, preferably, a case and a number of auxiliary rolling elements, resulting in rolling bearings having higher load capacity and reduced sliding friction, also a method to improve the conventional cylindrical roller bearings, the conventional ball bearings and the conventional thrust roller bearings.

1. A method for an improved rolling bearing,
the rolling bearing is comprising a first bearing ring (2a) having a first raceway (3a), a second bearing ring (2b) having a second raceway (3b), rolling elements (4) disposed between the first raceway (3a) and the second raceway (3b), each rolling element (4) is abutting onto both raceways (3a, 3b) and is transferring loads between them, the relative motion of the two raceways (3a, 3b) causes the rolling elements (4) to roll, each rolling element (4) neighboring with two other rolling elements (4), the method is characterized in that: an independent spacer (8) is being disposed between each pair of neighbor rolling elements (4), each independent spacer (8) is comprising a cage (6) and auxiliary rolling elements (5), the auxiliary rolling elements (5) of an independent spacer (8) abutting on the cage (6) of the independent spacer (8) and on two neighbor rolling elements (4) prevent the direct contact of neighbor rolling elements (4), so that the sliding friction reduces and the load carrying capacity of the rolling bearing increases.
