Embodiment 1

[0013] Embodiment 1: As shown in Figure 1, a high-speed bearing includes an inner ring 1 and an outer ring 2, and three middle rings 4 are coaxially arranged between the inner ring 1 and the outer ring 2, and the inner and outer sides of the middle ring 4 are respectively An annular groove 43 is provided, and four groups of rolling elements 3 are respectively arranged in the inner and outer annular grooves 43 of the three middle rings 4 .

Embodiment 2

[0014] Embodiment 2: As shown in Figures 2 and 3, a high-speed bearing includes an inner ring 1 and an outer ring 2, and three middle rings 4 and four sets of rolling elements are coaxially arranged between the inner ring 1 and the outer ring 2 3. The middle ring 4 includes a first middle ring cylinder 41 and a second middle ring cylinder 42 which are integrally arranged. The diameters of the first middle ring cylinder 41 and the second middle ring cylinder 42 change in a step shape. The diameter of the ring cylinder 41 is smaller than the diameter of the second middle ring cylinder 42, and the outer surface of the first middle ring cylinder 41 and the inner surface of the second middle ring cylinder 42 are respectively provided with annular recesses that can accommodate the rolling elements 3. Groove 43, four sets of rolling elements 3 are respectively arranged in the annular groove 43 on the outside of the first middle ring cylinder 41 and the inner side of the second middle ...

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. ...
