Embodiment 1

[0036] Example 1. refer to figure 1 . A thrust bearing using interface sliding technology, which includes a stationary plate 5 and a moving plate 4 parallel to each other, the gap between the stationary plate 5 and the moving plate 4 is filled with fluid lubricating oil, and the part of the stationary plate 5 The lower surface is provided with II coating 2, the remaining lower surface is provided with I coating 1, and the upper surface of the moving flat plate 4 is provided with III coating 3, so that a certain relative movement between the stationary flat plate 5 and the moving flat plate 4 Just make these two flat plates form a thrust bearing; the I coating 1 is a fluorocarbon coating; the II coating 2 and III coating 3 are mica powder coatings modified by a silane coupling agent.

Embodiment 2

[0037] Example 2. In the thrust bearing described in Example 1, the II coating 2 or III coating 3 is prepared by the following method: adding a silane coupling agent into an organic solvent to form a solution with a concentration of 0.1%, and using the silane coupling agent Add the mica powder into the solution at a ratio of 1:100 by weight of the coupling agent to the mica powder, mix evenly, apply the mixture on the surface of the static plate 5 or the moving plate 4, and form a coating after air-drying.

Embodiment 3

[0038] Example 3. In the thrust bearing described in Example 1, the II coating 2 or III coating 3 is prepared by the following method: adding a silane coupling agent into an organic solvent to form a solution with a concentration of 0.3%, and using the silane coupling agent Add the mica powder into the solution at a ratio of 2:100 by weight of the joint agent and the mica powder, mix evenly, apply the mixture on the surface of the static plate 5 or the moving plate 4, and form a coating after air-drying.

Abstract

The present invention is a kind of thrust bearing using interface sliding technology, which is characterized in that it includes a stationary flat plate and a moving flat plate parallel to each other, the gap between the stationary flat plate and the moving flat plate is filled with fluid lubricating oil, Part of the surface is provided with II coating, the remaining surface is provided with I coating, and the surface of the moving plate is provided with III coating, so that a certain relative motion between the stationary plate and the moving plate makes the two plates form Thrust bearing; the I coating is a fluorocarbon coating; the II coating and III coating are mica powder coatings modified by a silane coupling agent. The bearing of the present invention has a simple implementation method, has a certain load capacity and good anti-friction and wear-resistant properties, does not need to process the geometric shape of the mating surface, has a simple and compact structure, small size, and low manufacturing cost, and can replace traditional fluid dynamic pressure lubrication. Thrust plain bearings are used for load bearing.

Description

technical field [0001] The invention relates to a bearing, in particular to a thrust bearing using interface sliding 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 bear...
