The application provides a kind of measurement fixed combination device of planetary
gear train and its
assembly method, belong to planetary
gear transmission technical field, the device is installed in the inside and above of sun gear and star wheel shaft
assembly, the device includes: fixed mandrel mechanism and joint fixing mechanism;Fixed mandrel device includes mandrel, cone sleeve, nut, pin, anti-rotation screw, for fixed planetary
gear train sun gear, prevent its rotation and axial string movement;Joint fixing device includes mounting body, positioning shaft,
bushing, positioning collar, positioning pin shaft, pin shaft
bushing, screw, for realizing relative fixation between sun gear and star wheel shaft
assembly, finally realize sun gear and star wheel shaft assembly are fixed simultaneously.By the application, sun gear and star wheel shaft assembly in planetary
gear train can be fixed simultaneously, prevent its rotation and axial string movement in the measurement process, the function of measurement fixed combination device can be realized, improve product assembly, measurement efficiency, ensure the reliability of measurement data.
