Problems solved by technology

Due to the moderate aspect ratio, the bearing relies on the convergent wedge-shaped pores to form the lubricating film pressure, but the lateral leakage of the fluid reduces the lubricating film pressure and bearing capacity; the smaller the aspect ratio, the more serious the lateral leakage, and the bearing capacity The greater the reduction

Embodiment

[0043] Embodiment A thin layer of material is coated on the bearing bush or the hole wall of the bearing seat 2 in the entrance area of ​​the convergent wedge-shaped pores of the bearing, and the interface between the lubricating oil and the coating material has low adsorption strength and shear strength. When the bearing seat is stationary and the shaft 1 rotates during operation, the lubricating oil slips on the surface of this part of the coating material. Slip occurs.

[0044] According to the radial load direction of the bearing under the working conditions, the surface-treated bearing bush or bearing seat 2 hole wall is matched with the shaft 1 through installation, and there is a small gap formed between the bearing bush or the bearing seat 2 hole wall and the shaft 1. filled with lubricating oil. In this way, the rotational movement of the shaft 1 in a certain direction during work can form a lubricating oil film in the pores of the bearing hole 5, thus forming the be...

Abstract

The invention provides a novel energy-saving radial sliding bearing, which is formed by matching a shaft and a bearing sleeve hole or bearing block hole. A bearing sleeve hole wall or bearing block hole wall at an inlet region of a convergent wedge-shaped pore of the bearing is coated by a thin layer material, and the surface-treated bearing sleeve hole wall or bearing block hole wall is paired with the shaft; a gap formed between the bearing sleeve hole wall or bearing block hole wall and the shaft is filled with lubricating oil. The novel energy-saving radial sliding bearing designed by adopting an interface slip technology and adopting a surface coating method has the advantages of great carrying capacity, low coefficient of friction and excellent energy-saving performance. Compared with the traditional interface-slip-free radial sliding bearing, the bearing provided by the invention has the advantages of obviously improved carrying capacity, and obviously improved antifriction and energy-saving performances, thus having an important application value.

Description

technical field [0001] The invention relates to a novel energy-saving centripetal sliding bearing. Background technique [0002] Bearings are important mechanical components used to support shaft parts, and 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. [0003] 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 bearings, the existing types an...
