Elevator cast iron wheel

Elevator cast iron wheel is an important part of the elevator operation system, with the following characteristics and applications:

Features:

High strength: Cast iron has high strength and hardness, can withstand large mechanical stress and load, and can stably support the weight of the car, the weight of the heavy and other components and various dynamic loads during the operation of the elevator, to ensure the safe operation of the elevator.

Good wear resistance: The wear resistance of cast iron material is good, and in the process of frequent use and contact friction with steel wire rope and other parts, it can maintain a good surface state, reduce the wheel size change and performance decline caused by wear, and has a long service life.

Good shock absorption performance: Cast iron has certain shock absorption performance, which can reduce the vibration and noise generated during the operation of the elevator, so that the elevator runs more smoothly and quietly. However, its shock absorption performance is weaker than materials such as nylon wheels.

High dimensional stability: Cast iron has good dimensional stability, low thermal expansion coefficient, in different temperature environments, its size change is small, can ensure the accuracy of the elevator with other parts.

Application scenario:

Guide wheel: In the elevator's guide system, the cast iron guide wheel guides the car and the counterweight along the guide rail smoothly. It can lengthen the distance between the wire rope, separate the weight and the car, and ensure the correct operation of the elevator in the vertical direction.

Reverse rope wheel: The reverse rope wheel is usually installed on the top of the elevator car and the bottom of the counterweight device to change the direction of the wire rope. The cast iron reverse rope wheel can withstand the tension and friction of the wire rope to ensure the normal transmission of the elevator.

Car top wheel: located at the top of the elevator car, with the traction wheel and steel wire rope to achieve the lifting movement of the car. Cast iron car top wheel can provide stable support and guidance for car operation.
