Wear-resistant Iron Castings for Elevator Wheel Parts with Bearings

Technical Description of Elevator Wheel

Elevator wheels, as the core components of the elevator system, are usually made of high-quality cast iron materials to ensure their high strength, wear resistance and long-term stability. They drive the elevator car and counterweight up and down through friction transmission with the wire rope. The elevator wheel is precisely processed and heat-treated, with high surface hardness and good wear resistance, and can withstand huge tension and pressure. In addition, the design of the elevator wheel also takes into account noise reduction and shock absorption functions to reduce noise and vibration during elevator operation and improve passenger comfort.

1. Material and Process Characteristics

Mainstream products are mostly made of HT250 gray cast iron or QT450 ductile iron and are formed by sand casting or lost foam casting. Gray cast iron has good shock absorption and wear resistance, while ductile iron has increased the tensile strength by 30%-40% while maintaining the casting advantages. Advanced smelting technology enables the surface roughness of the casting to be controlled within Ra12.5μm, and the wall thickness tolerance can reach CT8 level precision, effectively ensuring the dimensional stability of the product.

2. Structural Design Features

The shell adopts an volute flow channel design, and the cross-sectional area of the flow channel increases according to the law of equal annular volume, ensuring smooth airflow and reducing kinetic energy loss by more than 18%. The main structure is equipped with radial reinforcement ribs, and the thickness of the key pressure-bearing parts is increased to 1.3 times the reference wall thickness, and the static load capacity can reach 10kN/m². The air inlet and outlet flanges are strictly processed according to ISO5801 standards and equipped with sealing grooves and positioning stoppers to ensure the air tightness of the system. The built-in guide baffle and silencer cavity design reduces the working noise by 6-8dB(A) compared with the traditional welded shell.

3. Performance Advantages

1. The overall casting structure eliminates the risk of stress concentration in the weld, and the fatigue life is increased by 3 times

2. The precision molding process ensures that the flow channel line deviation is ≤0.5mm and the aerodynamic efficiency is increased by 12%

3. The double-wall hollow structure is equipped with heat dissipation fins to achieve temperature rise control ≤35K

4. The standardized interface design is compatible with the GB/T 19075 standard impeller assembly

4. Application Adaptability

Our company focuses on the production of high-quality cast steel and cast iron parts, especially in the field of elevator wheels. We have a variety of models to meet the needs of different customers.

Our elevator wheels are mainly divided into two categories: traction wheels and guide wheels. The traction wheel is a key component in the elevator system. It is in direct contact with the wire rope, transmits power through friction, and drives the elevator car up and down. The traction wheel we produce is made of high-strength cast iron material. After precision casting and heat treatment, the surface hardness is high and the wear resistance is good. It can maintain a stable friction coefficient for a long time to ensure the smooth operation of the elevator.

The guide wheel is mainly used to change the direction of the wire rope to ensure the stable operation of the elevator in the vertical and horizontal directions. Our guide wheel has a reasonable design, compact structure, light weight, easy installation, and can effectively reduce the noise and vibration during the operation of the elevator.

For elevator systems of different specifications, we also provide elevator wheels of various sizes for customers to choose from. Whether it is a commercial building, a residential building or an industrial facility, we can provide the most suitable elevator wheel solution according to your specific needs. Our elevator wheel products are not only reliable in quality, but also reasonably priced, making them an ideal choice for upgrading and maintaining your elevator system.
