[0002] The elevator guide wheel is a key component in the elevator system. It is installed on the top of the elevator main unit or other designated locations to guide the movement trajectory of the elevator cable or traction rope to ensure that the elevator can run smoothly and safely along the predetermined path. The guide wheel is made of high-strength, wear-resistant and corrosion-resistant materials, and maintains stable performance and life during long-term use. The elevator guide wheel uses the pulley principle, cooperates with the traction motor and traction wheel to realize the lifting and lowering movement of the car and counterweight. At the same time, the guide wheel can also increase the distance between the car and the counterweight, change the movement direction of the wire rope, and play a limiting role. In order to ensure the safe operation of the elevator, the maintenance of the guide wheel is very important. During maintenance, the appearance, wheel groove, bearing and other parts of the guide wheel need to be regularly checked, and repaired or replaced in time when defects are found.
