Novel channel single-row centripetal ball bearing

Abstract

The invention discloses a novel groove single-row centripetal ball bearing. The existing single-row centripetal ball bearing can not simultaneously realize the relative high speed revolution and reduce the mutual displacement and / or shaking of an inner ring and an outer ring while bearing the larger radical force. The novel bearing comprises the outer ring, the inner ring, a retainer and a plurality of rolling balls. The outer ring is provided with an outer ring groove and the inner ring is provided with an inner ring groove. A plurality of rolling balls are arranged between the outer ring groove and the inner ring groove and keep a special distribution mode by the retainer. The novel bearing is characterized in that the line profile of the cross section of the outer ring groove and / or the inner ring groove at least comprises a high speed line profile which is arranged at the bottom and suitable for high speed revolution and an anti-channeling line profile which is arranged on two lateral parts; wherein the high speed line profile guarantees that the single-row centripetal ball bearing can realize the relative high speed revolution of the inner ring and the outer ring while bearing the larger radical force, and the anti-channeling line profile reduces the mutual displacement and / or shaking of the inner ring and the outer ring, thus achieving the purpose of the invention.

Description

technical field [0001] The invention relates to a bearing, in particular to a ball bearing which simultaneously takes into account high-speed rotation and reduces axial movement. Background technique [0002] The cross-sectional lines of the inner and outer ring channels of the existing single row radial ball bearings are mostly arc lines with a curvature greater than the ball radius, and the balls and the inner and outer ring channels are in the form of two-point contact, that is, the balls and the inner ring channels There are two contact points, one point contact with the groove bottom of the groove and one point contact with the groove bottom of the outer ring groove. The high-speed rotation performance of this single row radial ball bearing depends on the heat generated by the groove during rotation, and the amount of heat generated It is negatively correlated with the curvature of the arc lines of the inner and outer ring grooves, that is, the greater the curvature, th...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved and the technical task proposed by the present invention are to overcome the fact that the existing single-row radial ball bearings cannot realize the relatively high-speed rotation of the inner and outer rings and reduce the inner and outer rings while taking into account the characteristics of bearing large radial forces. To overcome the defects of mutual movement and / or shaking of the rings, a new type of grooved single row radial ball bearing is provided
