轴承零件的主要性能表征是接触疲劳寿命、尺寸稳定性和压破功。它们能较可靠地反映轴承的使用寿命和质量。这些指标的优劣又受原材料的成分、冶炼质量、冷加工精度和热处理工艺的发展等因素所控制。热处理工艺的改革和创新是其中最有效和重要的途径,早就受到人们的重视和采用并已经发挥了巨大的效益。近年来,新工艺不断涌现,对轴承使用寿命的提高显示了美好前景。现在介绍几种轴承零件热处理新技术和它们使性能跨数量级地得到改善的效益,供国内轴承行业的同志们在进行技术改造时参考。
The main performance characteristics of bearing components are contact fatigue life, dimensional stability and crushing work. They can more reliably reflect the bearing life and quality. The merits of these indicators by the composition of raw materials, smelting quality, cold processing precision and heat treatment process and other factors controlled. The reform and innovation of heat treatment process is one of the most effective and important ways, which has long been valued and adopted by people and has exerted tremendous benefits. In recent years, the new technology continues to emerge, shows a bright future for the improvement of bearing life. Now introduce several new heat treatment parts bearing technology and their performance across the orders of magnitude to be improved for the domestic bearing industry comrades in the technical transformation of the reference.
