The action mechanism of influencing factors on the reliability of space drive mechanism was studied. According to the main internal factors that affect the reliability of space drive mechanism, such as material, machining accuracy, assembly error and preload, different failure modes caused by different influencing factors were analyzed. The evolution law of space drive mechanism under different temperature, different speed, and different load were studied. The high and low temperature performance test device of space drive mechanism was used to test driving precision and efficiency of space drive mechanism changing with temperature, speed and load. The test results show that transmission accuracy of space drive mechanism decreases with temperature increasing, and the speed has little effect on transmission accuracy of space drive mechanism. The transmission efficiency of space drives mechanism increases with temperature and load increasing, transmission efficiency decreases with speed increasing.
