机床主轴承制造数据集
收藏资源简介:
在解析、对比和研究国内外先进精密机床轴承的基础上,结合稀土轴承钢材料研究、热处理研究、陶瓷体研究,进一步研究了加工制造过程中热处理、粗磨、精磨、超精等工序对轴承变质层应力的影响,结合轴承受力分析、设计轴承结构,形成加工、装配精度控制技术规范,依托轴承制造企业进行P4级及以上高精度系列型号机械主轴轴承加工生产。2020年9月至2022年4月,自主轴承已完成1118颗装机试用工作,从使用结果可以看出:自主轴承在精度及精度保持性均与德国GMN、日本NSK轴承性能水平相当,甚至部分性能指标有超出。
Based on the analysis, comparison and research on advanced precision machine tool bearings at home and abroad, combined with studies on rare earth bearing steel materials, heat treatment and ceramic components, this work further investigated the effects of processes including heat treatment, rough grinding, fine grinding and superfinishing during manufacturing and processing on the stress in bearing metamorphic layers. Through bearing force analysis and structural design of the bearings, technical specifications for machining and assembly precision control were established. Relying on bearing manufacturing enterprises, machining and production of high-precision series mechanical spindle bearings meeting P4 grade and above standards were carried out. From September 2020 to April 2022, 1118 units of the self-developed bearings have completed trial installation and operation. As revealed by the trial results, the self-developed bearings are comparable to German GMN and Japanese NSK bearings in terms of precision and precision retention, and even outperform in some performance metrics.
