Abstract

The invention discloses a wear-resistant bearing rolling body. The wear-resistant bearing rolling body is obtained by performing pressurized soaking on a bearing rolling body by adopting a coconut oil-sodium glutamate solution, adding the bearing rolling body into a low-temperature plasma treatment device for performing low-temperature plasma treatment after the bearing rolling body is cleaned and dried, wherein the treatment time is 70 to 80 seconds; after the treatment is completed, adding the bearing rolling body into a micro-arc oxidizing device for performing micro-arc oxidizing treatment within 60 seconds, wherein the treatment time is 2 to 3 minutes; then, performing soaking treatment on the bearing rolling body in castor oil; and after the bearing rolling body is soaked, taking the bearing rolling body out, and wipe-drying the surface of the bearing rolling body. The wear resistance of the bearing rolling body can be remarkably improved by treating the bearing rolling body by the method provided by the invention.

Description

technical field [0001] The invention belongs to the technical field of bearings, and in particular relates to a rolling body of a wear-resistant bearing. Background technique [0002] Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient (friction coefficient) during its movement, and ensure its rotation accuracy (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 body and cage. As a part of the bearing structure, the rolling body plays a very significant role. The rolling body direct...
