METHOD FOR ENSURING THE QUALITY OF MANUFACTURING AN ELECTROMECHANICAL DEVICE OF A SPACECRAFT Russian patent published in 2022 - IPC B64G1/50 

FIELD: electromechanical devices.

SUBSTANCE: invention relates to electromechanical devices of spacecrafts (SC), in particular electric pump units (EPU), antenna drives, etc., mainly telecommunications satellites, which must function without failure for at least 15 years under the conditions of operation of the SC in orbit. The method to ensure the quality of manufacturing of the electromechanical device of the spacecraft is that the quality control of heat treatment is carried out in several stages. At each control and before the standard installation, the rotor is pre-installed in the cavity of the stator shielding sleeve with the possibility of free extraction of the rotor from it, after that the electric drive is attached to the technological stand, a gradually increasing force is applied to the end of the shaft until the rotor is removed from the cavity of the stator shielding sleeve and the measured value is recorded. the maximum amount of force in the process of extracting the rotor. Then, the value of the total normal force that acted on the surfaces of the outer races of the bearings in the process of extracting the rotor, and the value of the allowable total normal force on the surfaces of the outer races of the bearings in the process of extracting the rotor, are determined in the case of high-quality heat treatment of the stator shielding sleeve and, based on the results of comparing the above values of normal forces, judge on the quality of manufacture of the electric drive of an electromechanical device.

EFFECT: improved quality of manufacturing of electromechanical devices.
