Corrosion-resisting and stamping-resisting bearing and preparation method thereof

Abstract

The invention discloses a corrosion-resisting and stamping-resisting bearing. The corrosion-resisting and stamping-resisting bearing is composed of, by weight, 0.48-0.72% of carbon, 0.48-0.60% of silicon, 0.85-0.94% of chromium, 0.45-0.62% of molybdenum, 0.22-0.35% of nickel, 0.32-0.36% of tungsten, 0.50-0.55% of barium, 1.2-2.2% of copper, 0.3-0.5% of titanium, 0.025-0.035% of europium, 0.08-0.12% of magnesium, 0.18-0.34% of aluminum, 0-0.018% of phosphorus, 0-0.018% of sulphur, and the balance iron. Compared with the prior art, by reasonably arranging the matching ratio and the production process, the formed bearing has better comprehensive mechanical performance, especially the high corrosion resistance and stamping resistance properties, can remarkably prolong the service life, reduces the fault rate of a machine and increases the safety factor.

Description

technical field [0001] The invention relates to the technical field of bearing processing, in particular to a corrosion-resistant stamping bearing and a preparation method thereof. Background technique [0002] Bearings are important and indispensable basic components in contemporary mechanical equipment. Although its rise is only more than a hundred years old, all countries in the world have spared no effort to develop their own bearing industries because of their relationship with the national economy and people's livelihood. With the help of superb modern science and technology, the bearings have produced more than 100,000 varieties with excellent quality and superior performance. The development of the world's machinery industry and other industries has made outstanding contributions to the progress of human society. [0003] However, the development level of the bearing industry is uneven, even very different. Bearing wear is a common equipment problem during the use ...

AI Technical Summary

Problems solved by technology

Bearing wear is a common equipment problem during the use of bearings, which is mainly caused by the metal characteristics of the bearing: although the metal has high hardness, its impact resistance is poor, so it is easy to cause wear and is not resistant to high temperature

Although the bearings produced at present have improved their corrosion resistance, they generally have the problem of poor wear resistance and impact resistance, and the smelting process is complicated, the production cycle is long, and the production efficiency is low.
