How to Choose Drive Wheel Block for Cranes
Cranes drive wheel block is the core component of the crane operation system, which directly affects the equipment's carrying capacity, walking stability and service life. Choosing a suitable drive wheel can not only improve work efficiency, but also reduce the cost of subsequent maintenance.
Clarify the use conditions and load requirements
● Clean workshop: such as semiconductor, pharmaceutical, and food industries, stainless steel or polyurethane rubber-coated wheels are required to prevent corrosion, low noise, and easy to clean.
● Outdoor heavy load: such as ports and metallurgical industries, high-strength alloy steel wheels are required, which are surface quenched and have impact and wear resistance.
● Special working conditions: high temperature resistant bearings, polyurethane rubber coating or customized anti-corrosion coatings can be selected for high temperature and strong corrosion environments.
● Calculate the static load and dynamic load of the wheel set according to the maximum working load of the crane. It is usually recommended to select a wheel set with a rated load ≥WLL×1.25～1.5 to ensure safety margin.
Structural type of drive wheel block
● Single wheel set: simple and economical structure, suitable for light load or simple track system. However, the lateral force resistance and stability are poor, and it is not suitable for heavy load and high speed occasions.
● Double wheel set: it consists of a pair of active wheels and passive guide wheels, which can evenly distribute the load and improve walking stability. It is widely used in heavy-duty bridge and gantry cranes.
● Integrated drive wheel set: the motor, reducer, brake and wheel set are integrated, which is quick to install, takes up little space, and the components are designed in a coordinated manner, which makes the operation smoother.
Material and processing technology
● Material selection: high-quality alloy steel or ductile iron material, stainless steel, polyurethane and other rubber-coated materials can be selected according to the working conditions.
● Heat treatment process: the wheel diameter surface should be quenched or carburized to improve wear resistance and fatigue resistance.
● Processing accuracy: coaxiality, wheel rim roundness and width tolerance are directly related to track wear and walking stability.
Matching with transmission components
● Motor and reducer: ensure that the motor power, speed and reduction ratio match; the reducer performance should meet the working conditions of repeated start and stop and high dynamic load.
● Braking system: according to the operating speed and load inertia of the crane, select the appropriate brake type to ensure the reliability of emergency stop.
● Sealing and lubrication: the bearings must be sealed in accordance with the IP level, such as IP65 or above; the lubrication method can be grease lubrication or circulating oil lubrication, depending on the working temperature and environmental pollution.
