High speed bearing

Abstract

There is disclosed a high-speed bearing, which includes an inner race and an outer ring. Between the inner race and the outer ring is disposed at least one middle ring. Inside and outside the middle ring is separately disposed a rolling element, so that the speed of the whole bearing has greatly increased. When one set of rolling elements breaks down, the other rolling elements can go on operating.

Description

technical field

[0001] The invention relates to a bearing, in particular to a high-speed bearing. Background technique

[0002] Existing bearings are generally composed of inner rings, outer rings, rolling elements and rolling element separators, and currently various so-called transmission bearings, load bearings, grinding bearings, insulating bearings, gas bearings and magnetic bearings etc. are all evolved on this basis to improve the design. In various types of equipment, the rotational speed of the bearings often limits the rotational speed of the rotating shaft in the equipment. In order to increase the rotating speed of the rotating shaft, people have designed various high-speed bearings. As disclosed in the No. 02151152.7 Chinese invention patent application publication published on June 23, 2004, a high-speed bearing is composed of an inner ring, an outer ring and a rolling bearing. A slender cylindrical needle roller is placed between every two rolling elements. ...
