Embodiment Construction

[0049] The present invention will be further described below in conjunction with accompanying drawing.

[0050] Such as figure 1 As shown, the deep groove ball bearing lubricated in the micro-textured auxiliary contact area includes outer ring 1, inner ring 2, cage and ball 3; the inside of the cage is movably connected with balls, and the balls are inner and outer under the action of the cage. rolling between the rings; the ball 3, the outer ring 1 and the inner ring 2 all constitute a rolling friction pair, which is consistent with the prior art; and different from the prior art, a micro Texture, micro-texture opening position is determined according to the working conditions of deep groove ball bearings in the following two situations:

[0051] 1) When the ratio E of the axial force to the radial force at each moment in the working condition of the deep groove ball bearing is less than 0.2 (that is, it is considered to be only subjected to radial force, this is the working...

Abstract

The invention discloses a deep groove ball bearing lubricated by a micro-texture auxiliary contact area and a processing method for inner and outer rings thereof. How the grease provides continuous lubrication to the contact zone has always been a concern. According to the working condition of the deep groove ball bearing, the present invention determines the position of the contact area between the ball and the raceway of the outer ring or the inner ring. Texture, change the wettability of the material through the density of the micro-texture, realize the spontaneous return of the base oil leaked from the grease accumulated on both sides to the contact area, so as to improve the state of thin oil film thickness in the contact area of ​​the bearing and improve the lubrication The effect is to increase the working life of the bearing.

Description

technical field [0001] The invention belongs to the technical field of rolling bearings, and in particular relates to a deep groove ball bearing lubricated by micro-texture-assisted contact areas and a processing method for inner and outer rings thereof. Background technique [0002] Rolling bearings are one of the most commonly used parts on mechanical equipment. They have the advantages of small frictional resistance, high mechanical efficiency, interchangeability, compact structure and easy start-up. They are widely used in various fields of national economy and national defense. One of the key components for stable, safe and long-life operation of equipment. [0003] Rolling bearings need to add lubricants for lubrication during use. The main purpose of rolling bearing lubrication is to reduce the friction and wear of bearing components during operation by creating a lubricating film between relative moving surfaces, thereby prolonging the service life of the bearing. ...
