Description

A device for removing and modifying elevator traction sheave

technical field

The utility model relates to the technical field of elevator traction sheave maintenance, in particular to an elevator traction sheave free-of-removal and shape-repairing device.

Background technique

The traction sheave is the sheave on the traction machine. It is a device for the elevator to transmit traction power. It uses the friction force between the traction wire rope and the rope groove on the traction wheel rim to transmit power. It is installed on the worm wheel shaft in the reducer. The traction force driven by the traction wheel to drive the elevator is generated by the friction between the traction rope and the traction wheel groove. The shape of the traction wheel groove is directly related to the size of the traction force and the service life of the traction rope.

The rope groove of the elevator traction sheave is worn due to long-term use. When the wire rope touches the bottom of the rope groove, it will cause slippage between the wire rope and the traction sheave, and cannot generate enough friction to pull the car. It is necessary to repair the wire rope groove of the traction wheel. When the wire rope groove of the traction wheel is reshaped and repaired, the traction sheave is usually removed and sent to a repair shop for repair. shape device.
