Embodiment 1

[0039] Example 1. refer to figure 1 . A thrust bearing using interface adsorption technology, which includes a stationary plate 1 and a moving plate 3 parallel to each other, the gap between the stationary plate 1 and the moving plate 3 is filled with a certain amount of fluid lubricating oil, the stationary plate 1 and the moving plate The mating surface of the plate 3 is smooth and smooth, and a coating 2 is provided on a part of the surface of the stationary plate 1. The moving direction of the moving plate 3 relative to the stationary plate 1 is from one end of the coating 2 of the stationary plate 1 to the other end of the stationary plate 1. In this way, certain relative motion between the two flat plates makes the two flat plates form a thrust bearing; the coating 2 is a mica powder coating modified by a silane coupling agent.

Embodiment 2

[0040] Example 2. Coating 2 described in embodiment 1 adopts following method to make: silane coupling agent is added in the organic solvent, is made into the solution that concentration is 0.1%, is 1: 100 with silane coupling agent and mica powder weight ratio Add the mica powder into the solution, mix evenly, and apply the mixture on the surface of the static plate 1, and form the coating 2 after air-drying.

Embodiment 3

[0041] Example 3. Coating 2 described in embodiment 1 adopts following method to make: silane coupling agent is added in the organic solvent, is made into the solution that concentration is 0.3%, is 2: 100 with silane coupling agent and mica powder weight ratio Add the mica powder into the solution, mix evenly, and apply the mixture on the surface of the static plate 1, and form the coating 2 after air-drying.

Abstract

The present invention is a thrust bearing using interface adsorption technology, which is characterized in that it includes a stationary flat plate and a moving flat plate parallel to each other, a certain amount of fluid lubricating oil is filled in the gap between the stationary flat plate and the moving flat plate, and the stationary flat plate The mating surface of the moving plate is smooth and smooth, and a coating is provided on part of the surface of the stationary plate. The moving direction of the moving plate relative to the stationary plate is from one end of the coating on the stationary plate to the other end of the stationary plate, so that there is a certain distance between the two plates. The relative movement of these two flat plates constitutes a thrust bearing; the coating is a mica powder coating modified by a silane coupling agent. The bearing of the present invention is a thrust plate sliding bearing with considerable bearing capacity and good anti-friction and wear-resistance properties; its realization method is simple, no geometric shape processing is required on the mating surface, the structure is simple and compact, and the size is small; the manufacturing cost is low.

Description

technical field [0001] The invention relates to a bearing, in particular to a thrust bearing using interface adsorption technology. Background technique [0002] Bearings are important mechanical components used to support shaft parts. Bearings are divided into sliding bearings and rolling bearings. There are the following main performance requirements for bearings: support accuracy, support rigidity, low friction coefficient and wear resistance. This requires the bearing to be a very precise mechanical part, and also requires it to have a large enough load-carrying capacity. In order to achieve good anti-friction and wear resistance, the bearing also needs to have good lubrication performance. So far, although the bearing technology is relatively mature, it is all based on the traditional lubrication theory. At present, rolling bearings and sliding bearings are used in different occasions and each has its own advantages. Since the present invention relates to sliding b...
