The method for detecting the backlash of the upper bearing of the gear box according to claim 5, wherein when the inner ring of the upper bearing of the gear box and the upper bearing roller move upwards together in the step S4, the upper bearing roller is in contact with the outer ring of the upper bearing of the movable gear box, the upper bearing roller is indicated to move into position, and the axial backlash I of the bearing of the gear box is recorded through a dial indicator;
When the inner ring of the lower bearing of the gear box moves downwards together with the lower bearing rollers, the lower bearing rollers are in contact with the outer ring of the lower bearing of the gear box, the lower bearing rollers are indicated to move in place, and the second axial play of the bearing of the gear box is recorded through a dial indicator.
7. A method of adjusting excessive bearing play of a gearbox using a tooling according to any one of claims 1 to 4, comprising the steps of: the outer thread sleeve is rotated, one end of the outer thread sleeve is enabled to push the U-shaped stress plate to continuously move downwards, the outer ring of the upper bearing of the gear box is driven by the U-shaped stress plate to move downwards, and therefore the axial clearance of the whole gear box bearing is adjusted until the axial clearance of the gear box bearing is qualified.
8. A method of adjusting gearbox bearing play to be too small using a tooling according to any one of claims 1 to 4, comprising the steps of:
Y1. reversely rotating the external thread sleeve, so that a gap is reserved between one end of the rotating external thread sleeve and the U-shaped stress plate;
Y2. moves up the control rod, and drives the gear box output shaft to move up through the upward movement of the rod, so that the inner ring of the upper bearing of the gear box and the upper bearing roller are driven to move up together, the upper bearing roller contacts with the outer ring of the upper bearing of the gear box, and after the upper bearing roller contacts with the outer ring of the upper bearing of the gear box, the outer ring of the upper bearing of the gear box is driven to move up continuously through the upward movement of the rod, so that the axial clearance of the whole gear box bearing is adjusted until the axial clearance of the gear box bearing is qualified.
