AI Technical Summary

Problems solved by technology

There is friction and wear in the conductive slip ring, the life is low, and the cost is high; in the existing solar panel drive mechanism, the ring-brush friction pair of the disc ring or the column ring is used to realize power and signal transmission
The conductive ring has the problems of complex structure, high cost, low reliability and heavy weight
In addition, the conductive ring generally needs to use a non-metallic insulating structure as a supporting structure, resulting in heavy weight and low rigidity, which affects the performance of the entire star

Embodiment Construction

[0021] The present invention will be further elaborated below in conjunction with embodiment.

[0022] Such as figure 1 As shown, the present invention provides a swing type solar panel drive mechanism, which drive mechanism includes a rotary transformer, a stepper motor, a harmonic gear, an output shaft, a housing, a torsion cable; the fixing of the stepper motor and the harmonic gear partially mounted on the housing, where:

[0023] The stepper motor is connected to the harmonic gear, which is used to decelerate the speed of the stepper motor and transmit the torque of the stepper motor shaft to the output shaft, which is used to connect the external solar panel to drive the solar panel to swing ; The resolver is used to measure the rotation angle of the output shaft; one end of the torsion cable is connected to the external actuator, and the other end is connected to the casing of the driving mechanism. The torsion cable is used to replace the disc ring to complete power ...

Abstract

The invention relates to a driving mechanism for a swing type solar sail panel, the structure includes a rotary transformer, a stepping motor, a harmonic gear, an output shaft, a casing, and a torsion cable; the fixed parts of the stepping motor and the harmonic gear are installed in the casing Above; the stepper motor is connected to the harmonic gear, the harmonic gear is used to decelerate the speed of the stepper motor, and transmit the torque of the stepper motor shaft to the output shaft, the output shaft is used to connect the external solar panel to drive the solar sail The plate swings; the resolver is used to measure the rotation angle of the output shaft; one end of the twist cable is connected to the external actuator, and the other end is connected to the housing of the drive mechanism. The present invention adopts the method that the torsion cable replaces the slip ring to realize the electric signal transmission, and realizes low weight, high rigidity, high reliability and long life.

Description

technical field [0001] The invention relates to a swing-type solar sail panel drive mechanism, which belongs to the technical field of space pointing and tracking mechanisms. Background technique [0002] The driving mechanism of the solar panel generally uses a conductive slip ring to realize the electrical connection between the rotating solar wing and the star. There is friction and wear in the conductive slip ring, the life is low, and the cost is high; in the existing solar panel drive mechanism, the ring-brush friction pair of the disk ring or the column ring is used to realize power and signal transmission. The conductive ring has the problems of complex structure, high cost, low reliability and heavy weight. In addition, the conductive ring generally needs to use a non-metallic insulating structure as a supporting structure, resulting in heavy weight and low rigidity, which affects the performance of the entire star. Contents of the invention [0003] The technic...
