Abstract

The invention discloses a locking disc assembling prepositioning device and an assembling method, and belongs to the field of locking discs. The problems that an existing locking disc assembling process is complex, labor and time are wasted and the assembling effect is poor are solved. The device comprises a screw rod and further comprises a cylinder and a piston arranged inside the cylinder. The lower end of the piston and the cylinder form an oil cavity. An oil inlet hole communicated with the oil cavity is formed in the outer wall of the cylinder. The lower end of the piston is fixedly connected with the screw rod. Prepositioning of an inner ring of the locking disc, a shaft sleeve and an outer ring can be achieved at a time, prepositioning is accurate and balanced, the bolt locking installation time is saved, labor force is saved, the assembling efficiency is improved, and the locking disc assembling prepositioning device has the advantages of being simple in structure, reasonable in design and easy to manufacture.

Description

technical field [0001] The invention belongs to the field of shrink discs, and in particular relates to a pre-positioning device for assembling a shrink disc and an assembly method. Background technique [0002] Shrink discs, such as wind power shrink discs, are used as locking devices for large wind turbines to connect components and transmit torque. The wind power shrink disc is composed of an inner ring, an outer ring, a shaft sleeve and several bolts. The existing wind power shrink disk assembly method is usually to tighten the two bolts symmetrically first to let the inner ring move into the outer ring for a certain distance, and then turn an angle to tighten the other two symmetrical bolts, and repeat these two steps many times. After the inner ring is pressed into the proper position of the outer ring, all the remaining bolts are then tightened. It takes many repetitions to assemble the wind power shrink disc in this way, which takes a long time and consumes a lot of...
