Elevator Door wire rope wheel Mitsubishi 90MM Elevator hanging wheel

The elevator wire rope sheave is a key component in the elevator system for supporting and guiding the wire rope. It mainly transmits power through the friction between the wire rope and the traction sheave, thereby achieving the rise and fall of the elevator. At the same time, the wire rope sheave also plays the role of supporting the weight of the elevator and guiding the path of the wire rope.

The elevator wire rope pulley is usually composed of a pulley frame, a pulley housing, a rope groove and a shaft. Its material is mainly engineering plastic or steel. The wear resistance of the plastic wheel housing is better than that of the steel wheel housing, but it is relatively weak in terms of load-bearing capacity and impact resistance. Therefore, when selecting the material, it is necessary to comprehensively consider the use environment and requirements of the elevator.

The working principle of the elevator wire rope pulley is mainly based on the pulley principle and friction control. When the traction wheel rotates, the friction between the wire rope and the traction wheel groove will drive the wire rope to move. At the same time, the wire rope pulley acts as a support and guide component to ensure that the wire rope can move smoothly on the track, thereby realizing the rise and fall of the elevator.

Elevator wire rope pulleys can be divided into many types according to different use environments and requirements. For example, some elevator wire rope pulleys use special grease to reduce the friction between the wire rope and the wheel groove, thereby extending the service life and reducing noise. In addition, some high-end elevators also use specially designed wire rope pulleys to improve the operating efficiency and stability of the elevator.

As a key component in the elevator system, the performance and quality of the elevator wire rope sheave directly affect the safety and stability of the elevator. Therefore, it is necessary to attach great importance to and strictly abide by relevant standards and specifications during the selection, installation, maintenance and maintenance process.
