Embodiment Construction

[0015] Embodiments of the invention are described in detail below, but the invention can be practiced in many different ways as defined and covered by the claims.

[0016] The invention discloses a surface anticorrosion treatment method for an air conditioner bearing, which comprises the following steps:

[0017] a. Carry out derusting treatment on the surface of the air conditioner bearing. The abrasive is a mixture of steel shot and steel grit. The steel shot in the abrasive is 35-55 parts, and the steel grit is 55-65 parts. The ratio is 1:1.1;

[0018] b. Use a degreasing agent to degrease the surface of the air conditioner bearing, then rinse the bearing with a water gun, and then dry it at a temperature of 140-180°C;

[0019] c. Nitriding treatment, preheat the air-conditioning bearing at 350-450°C for 70 minutes and then put it in a commercially available nitride-based salt bath at 700°C for 2-3 hours, wherein the nitride-based salt does not contain cyanide After high-...

Abstract

The invention discloses a surface anticorrosion treatment method for an air conditioner bearing. The method comprises the following steps that abrasive materials are used for conducting derusting treatment on the surface of the air conditioner bearing, a degreaser is used for degreasing, a water gun is used for washing the bearing, and then the air conditioner bearing is dried at 140-180 DEG C and subjected to nitriding treatment, oxidation treatment, polishing treatment and secondary oxidation treatment. Steel shots and steel emery are combined into the abrasive materials, impurities on the surface of the air conditioner bearing are completely removed, and the air conditioner bearing is subjected to nitriding, oxidation, polishing and oxidation treatment, so that the anticorrosion treatment of the surface of the air conditioner bearing is achieved, and the service life of the air conditioner bearing is prolonged.

Description

technical field [0001] The invention belongs to the field of air-conditioning bearings, and more specifically, the invention relates to a surface anticorrosion treatment method for air-conditioning bearings. 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 element and cage. Strictly speaking, they are composed of six parts: outer ring, inner ring, rolling...
