在轴承中,钢球常处于高压下高速工作。因此,制造钢球用的原材料应具备如下的要求:有高的接触疲劳强度,高的硬度,高的耐磨性,高的弹性极限,一定的韧性,好的尺寸稳定性,良好的工艺加工性能和一定的防锈性能。 一、制造钢球用的材料名称、 牌号及适用范围 按照冶金部的标准规定,我国的高碳铬轴承钢 In the bearings, the ball often work under high pressure high-speed. Therefore, the raw materials used in the manufacture of steel balls should have the following requirements: high contact fatigue strength, high hardness, high wear resistance, high elastic limit, a certain toughness, good dimensional stability, good processing technology Performance and some anti-rust properties. First, the name of the material used to manufacture steel balls, grades and scope of application In accordance with the Ministry of Metallurgical standards, China’s high-carbon chromium bearing steel
