Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] see Figure 2-Figure 4 , a rolling bearing, including an outer ring 1, an inner ring 2, a plurality of rolling elements 3 and a cage 4. The inner peripheral surface of the outer ring 1 is provided with an outer ring raceway 11, and the outer peripheral surface of the outer ring 1 is provided with one or more annular grooves 7 along the circumferential direction. O-rings 6 that protrude outward from the outer peripheral surface, there are two or more than two here; the cross-section of the O-rings 6 is circular, and the two ends of the inner bottom surface of the groove 7 are rounded corners at the bottom of the groove . The outer peripheral surface of the inner ring 2 is provided with an inner ring raceway 22, and the plurality of rolling elements 3 roll between the outer ring raceway 11 and the inner ring raceway 22, and the...

Abstract

A rolling bearing comprises an outer ring (1), an inner ring (2), a plurality of rolling bodies (3) and a retainer (4). The outer peripheral surface of the outer ring (1) is provided with one or more annular grooves (7) along the circumferential direction; the groove (7) is provided with an O-shaped ring (6) protruding from the outer peripheral surface of the outer ring (1); the O-shaped ring (6) has a circular cross section; both ends of the inner bottom surface of the groove (7) are slot bottom circular beads; the O-shaped ring (6) has inner diameter tension rate x equal to (D1-D2)/D2, filling rate of area y equal to pi(d/2)<2>/[h*(D-D1)/2-(r<2>-pi*r<2>/4)*2], a crushing rate z equal to deltad / d, wherein x, y and z satisfy the relations of: 1.3%<=x<=5%, 50%<=y<100%, and 21%<=z<=30%. The rolling bearing is easy for installation and can reliably prevent the outer ring (1) from wriggling.

Description

technical field [0001] The invention relates to a bearing, more specifically to a rolling bearing, which is suitable for an anti-creep rolling bearing device with an O-ring, and belongs to the technical field of bearing design. Background technique [0002] Rolling bearing is a precision mechanical component that connects the rotating shaft and the bearing seat. It includes an outer ring, an inner ring, a plurality of rolling elements and a cage. Equipped with an inner ring raceway. During installation and use, the shaft is installed in the inner hole of the inner ring, and the inner ring matches the shaft and rotates together with the shaft; the outer peripheral surface of the outer ring is installed in the inner hole of the bearing seat. [0003] In general motors, industrial sewing machines, electric tools, servo motors, etc., rolling bearings are often subjected to unbalanced rotational loads or vibrations; therefore, slow macroscopic relative sliding occurs between the...
