摘　　要：通过对比接触疲劳试验机杠杆砝码加载和液压加载的优缺点,发现这两种方法都已经不适合对轴承越来越高的试验要求。为了优化加载性能,采用伺服电动缸加载技术,对接触疲劳试验机加载系统机械结构和电气测控系统进行了重新设计。试验结果表明,伺服电动缸加载响应速度快、精度高、稳定性好,并且具有低噪音和节能环保等优点,为保证轴承质量打下了坚实的基础。By comparing the advantages and disadvantages of lever weight loading and hydraulic loading of contact fatigue testing machine,it is found that both methods are not suitable for the increasingly high test requirements of bearings.In order to optimize the loading performance,the mechanical structure and electrical control of loading system were redesigned by using the servo electric cylinder loading technology for the contact fatigue testing machine.The test results show that the servo electric cylinder loading system has the advantages of fast loading response,high accuracy,good stability,low noise,energy saving and environmental protection,which lays a solid foundation for ensuring the bearing quality.
