Problems solved by technology

[0003] In terms of motor performance testing, the commonly used performance evaluation indicators are inertia time and ground friction torque. The traditional test method uses a stopwatch to test the inertia time, which has the problems of large test error and cumbersome operation.
Use the ball bearing torque tester to test the ground friction torque, because the ball bearing itself has a large resistance torque, which brings great interference to the test results and has the problem of low test accuracy

Abstract

The invention discloses a high-precision counter torque testing device for a gyro motor, and the device comprises a lower flat plate installation housing, an air source assembly, a front support member, a rear support member, a left support member, a right support member, a housing installation torquer sensor assembly, an air bearing, and an upper cover plate, the air bearing is connected with a switching tool, a front panel is connected with the left support member and the right support member, and the upper cover plate is connected with the lower flat plate installation housing. The rear panel is connected with the rear supporting piece, a rectangular electric connector, an air source adapter and a power supply connector are installed on the rear panel, a torquer sensor assembly outgoing line is welded to the rectangular electric connector, an air source assembly and the air source adapter are connected with the air bearing through pipelines, and a binding post is connected with the power supply connector. The upper flat plate is connected with the left supporting piece, the right supporting piece, the front supporting piece and the rear supporting piece. When the device is used for testing, a to-be-tested motor is mounted on the switching tool to form torque acting on the rotor shaft of the air bearing, and the torque is converted into a voltage signal through the torquer sensor assembly and is transmitted to the upper computer.

Description

technical field [0001] The invention belongs to the technical field of gyro motor testing, and relates to a high-precision counter torque testing device for a gyro motor. Background technique [0002] Gyro motors are widely used in aerospace, aviation, navigation, weapons and various precision instruments. The motor is usually composed of three parts: rotor, stator and bearing. After power on, the rotor rotates at a high speed to provide the required angular momentum. The stator acts as The fixed part is connected with the outer part, and the bearing is used as the core part to support the high-speed rotation of the rotor. In the links of motor production and assembly, acceptance test, routine test, delivery, quality monitoring, reliability evaluation and new product development, it is essential to test the performance of the motor. Use the test results to judge whether the motor bearing is qualified and whether the motor meets the requirements for use. [0003] In terms o...
