Problems solved by technology

The sleeves of the currently used sleeve-type sliding bearings are mostly hollow cylinders, and the inner surface of the cylinder is a smooth plane. This structural form is severely worn, and a large amount of lubricating oil will flow upward, resulting in shortened service life of the bearings.

Embodiment Construction

[0009] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the embodiments and accompanying drawings. The embodiments are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0010] In this embodiment, a wear-resistant bushing, such as figure 1 shown, including

[0011] A shaft sleeve body, the center of the shaft sleeve body 1 is provided with a shaft hole;

[0012] A wear-resistant group, the wear-resistant group includes grooves 3 placed on both sides of the shaft hole, and a plurality of bumps 2 arranged at equal intervals between the grooves 3, the bumps 2 are provided with frosted particles, and the bumps 2 Prepared by quenching.

[0013] The present invention is provided with a plurality of bumps 2 on the inner surface of the shaft sleeve body, and the bumps 2 adopt a quenching process, so that the inner wall...

Abstract

The invention relates to a wear-resistant shaft sleeve which comprises a shaft sleeve body and a wear-resistant group, wherein a shaft hole is formed in the center of the shaft sleeve body 1; the wear-resistant group comprises grooves formed in two side ends in the shaft hole and a plurality of salient points which are arranged in an equally spaced manner between the grooves; frosted particles arearranged on the salient points and the salient points are prepared by quenching. The wear-resistant shaft sleeve has the advantages of being reasonable in surface structure, high in hardness, good inwear resistance and long in service life.

Description

Technical field: [0001] The invention relates to a wear-resistant shaft sleeve. Background technique: [0002] Bearings can be divided into rolling bearings and sliding bearings. Among them, the rolling bearing is a commonly used standard part, which has the advantages of low friction coefficient, small starting resistance, etc., and is very convenient in design, use, lubrication and maintenance. Sliding bearings have certain advantages over rolling bearings in high speed, heavy load, high precision and when the bearing structure needs to be divided. Sliding bearings are characterized by high load carrying capacity, good vibration resistance, low noise and long life. Sliding bearings need to be designed separately, and the material is generally bearing alloy (also known as babbitt alloy) or bronze. The shaft sleeves of the currently used sleeve type sliding bearings are mostly hollow cylinders, and the inner surface of the cylinder is a smooth plane. This structural form ...
