| 摘 要： | 基于波形弹簧提出了一种针对空间驱动机构角接触轴承的预紧力方法；文中对波形弹簧进行了设计，对波形弹簧进行了常温、耐压后、高低温刚度试验，验证了波形弹簧刚度的稳定性；然后将波形弹簧安装在驱动机构中，使用压力传感器监测波形弹簧施加在轴承上的预紧力；最后将驱动机构连同波形弹簧、压力传感器进行了高低温试验。试验表明，该种方式对轴承施加的预紧力，在高低温条件下性能稳定，具备一定的工程可行性。

| Abstract: | Based on waveform spring, a preload method for angular contact bearing of space actuator is presented. Design for this spring, stiffness tests of room temperature, low-high temperature and after compression resistance are introduced. By the test results, stability of its stiffness is verified. Then, the waveform spring is fixed in the space actuator, and at the same time, the preload of waveform spring on the bearing can be controlled and measured by a pressure sensor. Feasibility, stability for the preload of waveform spring on the bearing and engineering value of this method are proved by low-high temperature test. |
