Ball bearing

Abstract

The invention particularly relates to a ball bearing, and belongs to the technical field of bearings. The ball bearing comprises a retainer assembly, the retainer assembly is composed of a main retainer and two retainer covers, the main retainer is provided with a guide pocket hole and a window hole with an embedded raceway on the outer diameter, the two retainer covers are connected with the window hole on the main retainer through convex points, and a metal linear raceway is embedded in the window hole on the outer diameter of the main retainer. The metal linear raceway is inlaid in the outer diameter window hole of the main retainer, the metal linear raceway and the main retainer form a loopback pocket hole, rolling bodies are linearly arranged in the metal linear raceway, and the rolling bodies are provided with loops in the pocket hole of the retainer assembly, so that the requirement for linear reciprocating motion of a mechanism can be met by connecting a motion shell and a mandrel; and meanwhile, the rolling bodies are linearly arranged in the metal linear raceway, and the rolling bodies are provided with the loops in the pocket hole of the retainer assembly, so that the linear motion structure is simple, and the size is small.

Description

technical field [0001] The invention specifically relates to a ball bearing and belongs to the technical field of bearings. Background technique [0002] Ball bearings refer to radial rolling bearings in which rolling bodies are balls. They are non-separable bearings. The inner and outer rings of the bearings have arc-shaped grooves. [0003] Due to global warming, it is necessary to control the fuel conversion efficiency of vehicles. Because ball bearings generate less frictional torque than roller bearings, ball bearings are often used in precision instruments such as vehicle gearboxes or engines. At present, the inner ball bearing used in the gearbox usually needs to rotate quickly, and the lubricating oil inside the bearing will be consumed quickly during the high-speed rotation, and the friction inside the bearing will increase after the lubricating oil is consumed, which will affect the normal operation of the bearing. Therefore, it is necessary to replenish lubricat...

Problems solved by technology

At present, the inner ball bearing used in the gearbox usually needs to rotate quickly, and the lubricating oil inside the bearing will be consumed quickly during the high-speed rotation, and the friction inside the bearing will increase after the lubricating oil is consumed, which will affect the normal operation of the bearing. running, so it is necessary to replenish lubricating oil to the bearings from time to time, resulting in cumbersome manual operations

And the high-speed rotation will also make the sundries in the bearing contact the steel ball through the lubricating oil, which will increase the friction of the steel ball and affect the normal use of the bearing.
