Deep groove ball bearing subjected to nickel coating treatment and machining method thereof

Abstract

The invention discloses a deep groove ball bearing subjected to nickel coating treatment, and relates to the technical field of bearings. The deep groove ball bearing comprises an outer bearing ring,an inner bearing ring and steel balls; the inner surface of the outer bearing ring and the outer surface of the inner bearing ring are in rolling connection with the surfaces of the steel balls correspondingly; steel ball retainers are arranged on the positions, between the outer bearing ring and the inner bearing ring, on the left sides and the right sides of the steel balls in a sleeving mode; and wavy circular grooves matched with the steel balls are formed in the inner surface of the outer bearing ring and the outer surface of the inner bearing ring correspondingly. According to the deep groove ball bearing subjected to nickel coating treatment and a machining method thereof, a thick nickel-chromium coating and a thin nickel-chromium coating are arranged to wrap the outer bearing ringand the inner bearing ring, thus the outer bearing ring and the inner bearing ring are not prone to being corroded, rusting is avoided during 72 hours of a salt spray test, and the abrasion-resistantstrength is improved; and frosted surfaces are arranged, thus the connecting strength of the coatings is enhanced, the coatings can be prevented from falling off easily, and meanwhile through specialstructures of the wavy circular grooves, the deep groove ball bearing cannot be abraded completely by the steel balls after being used for a long time.

Description

technical field [0001] The invention relates to the technical field, in particular to a nickel-coated deep groove ball bearing and a processing method thereof. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. According to the different friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, the rolling bearing has been standardized and serialized, but compared with the sliding bearing, its radial dimension, vibration and noise are larger, and the price is also higher. Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling elements and cage. According to the shape of rolling elements, rolling bearings are divided into two categories: ball bearings and roller bearings....

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a nickel-coated deep groove ball bearing and its processing method, which solves the problem of the general bearing being soaked and adhered by water or dirty lubricating oil after long-term use. The surface will be corroded, especially in the space where the rollers are located. If corrosion occurs, it will affect the lubricity of the rolling of the rollers, and then affect the overall performance of the bearing.
