Abstract

The invention proposes an automatic force exerting device and a method for an air floatation rotor gyroscope dynamic pressure motor gap measurement, which belong to the spaceflight inertial device precision technology field. The automatic force exerting device comprises three-axis precise displacement platforms, a control loop circuit, a force sensor installation plate, a dynamic pressure motor, a left side fixing plate, a right side fixing plate, a horizontal plate and a middle clamping device. The three-axis precise displacement platforms are mounted on the horizontal plate. The three precise displacement platforms are vertical to each other in the moving direction to form a Descartes rectangular coordinate system. The fixing devices at two sides are used to have the middle clamping device fixed, and the middle clamping device realizes the tight clamping of the dynamic pressure motor via the closed finger clamping body. The automatic force exerting device of the invention is applied to the method for measuring the air floatation rotor gyroscope dynamic pressure motor gap, and comprises two fixed ends and a tightly clamped middle to realize automatic circle adjustment and automatic force exertion. With the invention, it is possible to realize the continuous controlling and loading of force and to realize the automatic circle adjustment to a tested component based on the device of the invention.

Description

technical field [0001] The invention relates to the technical field of precise detection of aerospace inertial devices, in particular to an automatic force application and centering technology for gap measurement of an air-floating rotor gyroscope dynamic pressure motor. Background technique [0002] The structure of the dynamic pressure air bearing gyro motor is different from the general low-power drive motor and the frame gyro motor. There is a small gap between the inner ball cavity of the flywheel-shaped rotor and the ball of the fixed shell, which is a typical deformable device. When the rotor moves at high speed driven by the motor, dynamic pressure (suspension force) will be generated in the gap, which will make the rotor out of contact with the ball. The dynamic pressure generated in the appropriate gap will make the rotor stable in space under the action of its own weight or acceleration overload. The actual size of the gap should be determined according to the m...
