Abstract

The invention relates to a reaction wheel bracket, which is applied in the technical field of general assembly of overall spacecraft. The reaction wheel bracket comprises a reaction wheel installing surface, a bracket installing bottom surface and two bracket supporting bodies, wherein four installing holes are distributed above the reaction wheel installing surface and are used for fixing connection between a reaction wheel and the bracket; and four reinforcing ribs are distributed under the reaction wheel installing surface. The reaction wheel bracket has the advantages that the condition that the normal direction of the reaction wheel is parallel to a star-structure plate is realized, and the reaction wheel installing surface and the bottom surface of the bracket adopt an installing mode with a 90-degree installing angle; and more parts are provided with the reinforcing ribs under the condition of avoiding the interference with the reaction wheel so as to improve the strength and the rigidity of the bracket.

Description

technical field [0001] The invention relates to a reaction wheel bracket, which is applied in the technical field of general assembly of spacecraft. Background technique [0002] The general assembly technology of the spacecraft is to reliably fix the instruments and equipment of each subsystem to the required position, meet the installation requirements of the instruments and equipment, and ensure that the spacecraft can work normally under the influence of various stages and environments. The reaction wheel is the key attitude control component on the star, and it is an electromechanical actuator with a large inertia wheel body. Through the forward rotation or reverse rotation, acceleration or deceleration of the wheels, the reaction control torque is generated, and the momentum is exchanged with the star angle to realize the control of the satellite attitude. The reaction wheel is connected to the star structure plate through the bracket, so the bracket is required to ha...
