摘要
星载天线万向支架在空间要长期工作,驱动电机是其关键部件,应进行备份。通常空间应用的电机只进行绕组线圈的备份,无法进行整个电机的备份。介绍一种利用行星齿轮差动机构实现整个电机备份的方法。
The antenna gimbal operates continuously in space. The drive motor is one of its key components and should have a backup. Usually, the motor used in space keeps a backup of the coil instead of a whole motor. This paper gives a new solution to keep a backup of a whole motor by using a bevel differential gear.
