| 摘 要： | 固体润滑深沟球轴承寿命与所受负载息息相关。研制了轴系固有频率测试装置，通过该装置对固体润滑轴系轴承座不对中导致轴系受径向外力工况和轴系固有频率之间相关性进行了实验研究。对轴系固有频率随径向外力变化的测试数据进行了拟合分析。结果表明：轴系固有频率随径向外力增大而增大；径向外力和固有频率之间存在较为明显的幂函数关系；可以通过测试轴系固有频率来获取固体润滑轴承径向外力情况，径向外力拟合公式计算值与实测值之间相对误差不超过7%。

| Abstract: | The life of solid-lubricated bearings is closely related to load. A device is developed to test the natural frequency of shaft system. The correlation between radial load which is caused by bearing pedestal misalignment and natural frequency of solid-lubricated shaft systems were researched on this test rig. The natural frequency data of shaft systems changing with radial load were analyzed. The results show that the natural frequency of shaft systems increases with the rising radial load; the correlation between radial load and natural frequency presents a power function. The radial load of solid-lubricated shaft system can be obtained by testing the natural frequency. The relative error between calculated value and experimental value of radial load is not more than 7%. |
