Hand wheel is a rotating device operated by hand, usually consisting of a circular wheel and a shaft. Its main purpose is to control and adjust mechanical equipment through rotation.
They are usually used on industrial machinery and equipment, such as machine tools, lathes, grinders, milling machines, etc. It can be used to adjust the speed, position, pressure, and other parameters of mechanical equipment. By rotating the operators can accurately control and adjust various aspects of equipment operation, achieving high-precision processing and production.
In addition, They can also be used on some daily necessities, such as bicycles, motorcycles, etc. In these cases, the handwheel is used to operate the steering, braking, and other controls of the vehicle.
Usually, they are made of metal and plastic materials:
---Metal material: such as iron, aluminum, stainless steel, etc., with high strength and durability.
---Plastic material: such as polypropylene and polyvinyl chloride, with lightweight and low cost.
According to their functions, they can be divided into 3 types :
--- Adjusting handwheel: Used to adjust certain parameters of equipment or machinery, such as adjusting the speed and pressure of mechanical equipment.
--- Control handwheel: used to control the switch, start, stop, and other operations of mechanical equipment.
--- Rotating handwheel: used to complete the operation of specific mechanical equipment through human rotation, such as the steering wheel of a vehicle, the handle of a machine tool, etc.
The surface treatment of handwheels usually involves the following methods:
--- Nickel/chromium plating: Apply a layer of nickel or chromium to the surface to improve its corrosion resistance and appearance quality. This surface treatment method is commonly used on equipment such as automobiles, motorcycles, and machine tools.
---Carburization treatment: By heating and soaking the surface of the material in a medium containing carbon, the carbon penetrates into the interior of the material, forming a layer of hard surface. This treatment has high wear resistance and corrosion resistance.
---Oxidation treatment: Oxidizing the surface, such as anodizing, can form a dense oxide layer, increasing the hardness and wear resistance. This treatment method is commonly used for aluminum alloy products to improve their durability and appearance.
---Spraying coating: Using spraying technology, a layer of paint or special coating is sprayed on the surface to provide additional protection, anti-corrosion, scratch resistance, and other functions. This method is usually suitable for specific colors or special performance.
---Polishing: Polishing the surface by using mechanical or chemical methods to remove surface defects and roughness, resulting in a high level of smoothness and appearance quality.
The selection of an appropriate material and surface treatment method depends on the application environment, required functionality, and aesthetics. Various surface treatment methods can enhance the performance and appearance to meet specific needs.
Welong is good at both cast iron and stainless steel handwheels made out of grey iron and ductile iron, with chrome-plated surfaces or according to customer-specified requirements.
