Abstract

The invention discloses a manufacturing technique for a bearing. Through control over the normalizing and heat preservation time and temperature in heat treatment, deformation of a metal part can be reduced, energy consumption is saved, and the production cost is reduced; through control over the speed and the power of a grinding machine, the accuracy and the abrasion resistance of the bearing are further improved; through acid dipping after degreasing, on one hand, oxide on the surface of a steel pipe can be removed, as aftertreatment is carried out after surface grinding, the antiseptic property of the bearing can be improved, and the service life of the bearing is accordingly prolonged. The bearing produced with the method has the advantages of being high in fatigue resistance and long in service life; and the market potential is huge, and the prospect is wide.

Description

technical field [0001] The invention belongs to the production field of bearings, and more specifically, the invention relates to a production process of 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. The current bearings have the disadvantages of poor anti-corrosion performance and low fatigue resistance. Contents of the invention [0003] The problem to be solved by the present invention is to provide a production process o...
