Abstract

The invention discloses a quick assembly method and device for a return spring of a gearbox. The specific steps are as follows: turn the driving nut clockwise to make the driving nut move forward on the stroke screw, and then push the press-in sleeve and the spring tray to move forward. Press the return spring to the front of the first annular groove; then extend the shaft circlip installation pliers into the spring tray and spread the shaft circlip, and drive the shaft circlip to move forward to the first ring After the groove, loosen the shaft circlip installation pliers so that the shaft circlip is installed in the first annular groove; finally turn the drive nut counterclockwise to remove the drive nut from the travel screw, and then remove the Press down the sleeve, the spring tray and the fixed screw sleeve; thereby completing the installation of the return spring; through this technical solution, a single person can complete the installation of the return spring, which is efficient and fast; and the entire assembly process is controllable without causing secondary damage to the parts. injury.

Description

technical field [0001] The invention relates to the technical field of gearboxes, in particular to a quick assembly method and device for a return spring of a gearbox. Background technique [0002] In order to individually control the specific speed of the output shaft of the gearbox, a clutch (brake) is generally provided in the gearbox; including inner friction plates, outer friction plates, pressure bearing plates, annular pistons, return springs, and return brakes located in the box. The spring seat and the return spring screw, the pressure bearing plate, the outer friction plate and the axial movement of the first shell’s circumferential positioning, the inner friction plate and the first half shaft’s circumferential positioning and axial movement, and a plurality of ring-shaped inner friction plates and the outer friction plates are alternately stacked on each other, the annular piston moves between the braking position and the non-braking position, the return spring m...
