Problems solved by technology

At present, the gyro motor vibration acceleration and bearing stiffness testing equipment or devices used at home and abroad are mainly for the outer rotor type gyro motor, while the inner rotor type gyro motor needs a special fixing device when testing because the stator is located outside the rotor, and because the rotor is exposed The size and space of some effective measurement parts are limited, only 1.5mm to 2mm. Therefore, the vib

Abstract

The invention discloses an inner rotor type gyro motor testing device. A locknut (2) and a locknut (10) are in threaded connection with the big shaft end and the small shaft end of a gyro motor rotor (9). A testing support (8) and nut lock blocks (11) are matched to form a cylindrical cavity used for accommodating the locknuts. The locknuts are fixed to the testing support (8) through the two nut lock blocks (11). A gyro motor stator (6) is installed inside an upper stator installation seat (5). The gyro motor rotor (9) is installed inside the gyro motor stator (6), and the end face of the big shaft end of the gyro motor rotor (9) is matched with the bottom surface of the upper stator installation seat (5) for positioning. The end face of the small shaft end of the gyro motor rotor (9) is matched with the bottom surface of a lower stator installation seat (7) for positioning. The lower stator installation seat (7) and the upper stator installation seat (5) are locked through a connecting bolt (14). The inner rotor type gyro motor testing device can test the vibration acceleration and the bearing stiffness, and a testing method is simple and accurate.

Description

technical field [0001] The invention relates to a test device for a gyro motor, in particular to a device for testing the vibration acceleration and bearing stiffness of an inner rotor type gyro motor. Background technique [0002] Gyro motor vibration acceleration and bearing stiffness are one of the key technical parameters for inertial instrument operation stability and accuracy. Gyro motors are divided into outer rotor type gyro motors and inner rotor type gyro motors according to their structure. At present, the gyro motor vibration acceleration and bearing stiffness testing equipment or devices used at home and abroad are mainly for the outer rotor type gyro motor, while the inner rotor type gyro motor needs a special fixing device when testing because the stator is located outside the rotor, and because the rotor is exposed The size and space of some effective measurement parts are limited, only 1.5mm to 2mm. Therefore, the vibration acceleration and bearing stiffness...
