Description

A grinding device for elevator traction wheels

Technical field

The utility model relates to the technical field of traction sheave bodies, and in particular to a grinding device for elevator traction sheaves.

Background technique

The traction sheave is the sheave on the traction machine, also called the traction sheave or the driving sheave. The traction sheave is a device that transmits traction power in the elevator. It uses the friction between the traction wire rope and the rope groove on the traction sheave rim to transmit power. Since the traction sheave has to withstand all the motion of the car, load capacity, counterweight and other devices, Static load, therefore requires the traction sheave to have high strength, good toughness, wear resistance, and impact resistance, so ductile iron is often used as a material. In order to reduce the wear of the traction wire rope in the traction sheave rope groove, in addition to selecting a suitable rope groove In addition to the shape, there should be reasonable requirements for the roughness and hardness of the working surface of the rope groove.

Most of the traditional traction sheave grinding devices are not capable of fixing traction sheaves of different sizes. As a result, when traction sheaves of different sizes need to be fixed and polished, the staff need to change the fixture before they can fix the traction sheaves of different sizes. Grinding the traction wheel is time-consuming and labor-intensive, increases the unnecessary workload of the staff, and is inconvenient for the staff to use. At the same time, when grinding the traction wheel in the traditional way, most of the staff use a hand-held grinder to polish the traction wheel. The labor intensity is high and the degree of automation is low.
