Abstract

The invention relates to a variable inertia reaction flywheel. A flywheel shaft is linked with a flywheel outer ring by virtue of a guide bar; the flywheel shaft is arranged on a support by virtue of a deep groove ball bearing; the support is fixed on a left shell; a drive motor is fixed on the left shell, and the shaft of the drive motor is linked with the flywheel shaft by virtue of a flat key, so as to drive the flywheel to rotate; the guide bar is provided with a balancing weight which can slide along the guide bar; the flywheel shaft is provided with a guide rod of which the axis is superposed with the axis of the flywheel; the guide rod is provided with a slide block; the slide block is linked with the balancing weight by virtue of a connecting rod; the other end of the slide block is linked with a lead screw by virtue of a deep groove ball bearing; a right shell and a left shell are oppositely fixed; a through screw rod motor is arranged on the right shell; the lead screw motor drives the lead screw to do spiral movement; the lead screw drives the slide block to slide along the guide rod, so as to drive the balancing weight to slide along the guide bar, and thus the rotary inertia of a flywheel mechanism is adjusted; the counter torque output by the variable inertia reaction flywheel is controlled by controlling the angular speed of the drive motor and the angle of revolution of the lead screw motor.

Description

technical field [0001] The invention relates to a reaction flywheel, which belongs to the field of reaction flywheels used for attitude adjustment, in particular to a reaction flywheel with variable inertia. Background technique [0002] As a key component of attitude adjustment, the reaction flywheel has been widely used in the fields of satellites, one-wheeled robots and other aircraft and robots. A reaction flywheel is installed inside the object, and the attitude of the object can be controlled by driving the reaction flywheel to obtain the reaction torque. When the object performs rapid and large-angle attitude maneuvers, it generally requires a large reaction torque; while it requires a small amount of high-precision attitude adjustment. The reaction torque adjusts the attitude. Due to the limitation of the speed of the reaction flywheel and the control accuracy of the motor, a large reaction torque is generally provided, and a reaction flywheel with a large moment of...
