Problems solved by technology

According to conventional design ideas, the backup design of the driving device leads to a very complex structure and it is difficult to improve the overall performance of the product. Therefore, the existing solar array drive device does not have a backup design in the transmission mechanism. During the long-term operation on the track, due to friction and wear , prone to drive function failure

Abstract

The present invention relates to the application field of satellite technology, and proposes a back-up solar cell array drive device, including a main drive motor, a harmonic drive reducer, a main drive shaft, a conductive slip ring, a backup drive motor and a harmonic drive reducer, The spare drive shaft and the zero position sensor are several parts. The drive device adds a spare drive mechanism to the original main drive mechanism (including conductive slip ring). They are connected in series. When the main drive mechanism is used to work, the main drive shaft and the spare drive The mechanism is quite a whole and rotates together, and the solar battery array is installed on the shell of the drive mechanism to realize the orientation to the sun. When the standby drive mechanism is working, the lock torque of the main drive mechanism is used to fix the standby drive shaft, and the output of the standby drive shell rotates. The invention can realize the separate driving of the main and backup driving mechanisms, has the beneficial effects of simple structure and high reliability, and is suitable for use on satellites with long service life and high reliability requirements.

Description

technical field [0001] The invention relates to the application field of satellite technology, in particular to a back-up solar battery array driving device, which can effectively improve the reliability of the sun-oriented driving of the satellite solar battery array. Background technique [0002] The solar cell array drive device is an important stand-alone unit on a satellite (or spaceship), which mainly realizes the function of solar cell array orientation to the sun, and transmits the electric energy and measurement and control signals generated by the solar cell array to the satellite through conductive slip rings. Due to the importance and non-repairability of the driving device, its long-life reliability requirements are very high. According to conventional design ideas, the backup design of the driving device leads to a very complex structure and it is difficult to improve the overall performance of the product. Therefore, the existing solar array drive device does ...
