Deep groove ball bearing with good rust prevention effect and machining method thereof

Abstract

The invention discloses a deep groove ball bearing with good rust prevention effect and a machining method thereof, and relates to the technical field of deep groove ball bearings. The deep groove ball bearing comprises a bearing outer ring, a bearing inner ring and a retainer; the inner surface of the retainer is rotatably connected with balls; one sides of the outer surfaces of the balls are movably connected with the outer surface of the bearing inner ring; the other sides of the outer surfaces of the balls are movably connected with the inner surface of the bearing outer ring; an arc groove is formed in the bearing outer ring; and oil beads are rotatably connected with the interior of the arc groove. According to the deep groove ball bearing with the good rust prevention effect and themachining method thereof, rust prevention oil is introduced into the arc groove by feeding the oil through an oil inlet, so that the problems that the balls are prone to rusting and difficult to rotate and loud in noise can be effectively solved, the amount of the rust prevention oil is reasonably controlled, and the cost is reduced; and the bearing outer ring, the bearing inner ring and the retainer are all treated with a nickel coating technology and are not rusted after 72 hours of salt spray test, so that the service life of the deep groove ball bearing is prolonged.

Description

technical field [0001] The invention relates to the technical field of deep groove ball bearings, in particular to a deep groove ball bearing with good antirust effect and a processing method thereof. Background technique [0002] The original list of deep groove ball bearings is radial ball bearings, which are the most widely used rolling bearings. It is characterized by small frictional resistance and high speed, and can be used on parts that bear radial loads or combined loads that act simultaneously in radial and axial directions, and can also be used on parts that bear axial loads, such as small-power motors, Automotive and tractor gearboxes, machine tool gearboxes, general machines, tools, etc. Deep groove ball bearings are the most common type of rolling bearings. The basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cages. There are two types of deep groove ball bearings: single row and double row. The struc...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a deep groove ball bearing with good antirust effect and its processing method, which solves the problem that the balls inside the cage are prone to rust after a long time of use in the existing deep groove ball bearings. Rust, not easy to rotate, and the outer ring of the bearing is in direct contact with the air, and the surface needs to be frequently coated with anti-rust oil to prevent rust, which is a troublesome problem
