Abstract

The invention provides a deep groove ball bearing with wave-shaped retainers with oil holes and a machining method, and relates to the field of bearing retainers. The invention aims to solve the problem that there is a lack of methods to improve deep groove ball bearing lubricating condition by changing the structure of the deep groove ball bearing in the prior art. Each wave-shaped retainer is ofa circular ring structure and is composed of two wave-shaped half-retainer, a plurality of pocket holes are formed in the circumferential direction in each wave-shaped half-retainer, the two wave-shaped half-retainers are buckled, the steel balls are arranged in the pocket holes of the two wave-shaped half-retainers, and a through oil hole is formed in the bottom of each pocket hole of each wave-shaped half-retainer and is used for reducing the sliding friction and impact of the steel ball and the pocket hole.

Description

technical field [0001] The invention relates to a deep groove ball bearing with an oil hole wave-shaped cage. It belongs to the field of bearing cages. Background technique [0002] Deep groove ball bearings are suitable for high-speed or even extremely high-speed operation. This type of deep groove ball bearings has a small friction coefficient and a high limit speed. It mainly bears radial loads and can also bear a certain amount of axial loads. There are many deep groove ball bearings available. Groove ball bearings are lubricated to improve the lubrication performance of deep groove ball bearings, prevent failure of mechanical parts, and reduce friction between raceways, cages and rolling elements, but these lubrication methods use external lubricants to increase deep grooves For the lubricity of ball bearings, there is currently a lack of problems to improve the lubrication conditions of deep groove ball bearings by changing the structure of deep groove ball bearings. ...
