The selection of aluminum alloy as the material of synchronous wheel is mainly based on its many advantages, which make aluminum alloy stand out in the application of synchronous wheel and have significant characteristics compared with other materials such as steel, cast iron or plastic.
Advantages of aluminum alloy as synchronous wheel materialLightweight: The density of aluminum alloy is much lower than that of steel, so the synchronous wheel made is lighter. In the automotive industry, the use of aluminum alloy synchronous wheels can significantly reduce the weight of the vehicle body, which helps to improve the fuel economy and acceleration performance of the vehicle.Excellent thermal conductivity: Aluminum alloy has good thermal conductivity, which can dissipate the heat generated by the synchronous wheel at high speed more quickly, reduce overheating, and improve the stability and safety of the equipment.High strength and hardness: Although the density of aluminum alloy is low, it can obtain higher strength and hardness through alloying and heat treatment processes, which meets the use requirements of synchronous wheels under high speed and high load conditions.Good plasticity: Aluminum alloy has excellent plasticity and can be formed at high temperature. It is also suitable for precise processing by various processes such as cold extrusion and stamping. This makes the manufacture of aluminum alloy synchronous wheels easier and can also reduce costs.Good corrosion resistance: The surface of aluminum alloy can be properly treated (such as anodizing, corrosion-resistant blackening and anti-corrosion treatment, etc.) to significantly improve its corrosion resistance and extend its service life.Beautiful appearance: The surface of aluminum alloy synchronous wheels is smooth, the color is uniform, and the appearance is beautiful, which can enhance the grade of the whole vehicle.
Comparison with other materialsCompared with steel:Aluminum alloy synchronous wheels are lighter, which helps to improve fuel economy and acceleration performance.The thermal conductivity of aluminum alloy is better than that of steel, and the heat dissipation effect is better.However, steel is usually more wear-resistant and stress-bearing, suitable for heavy-duty transmission.Compared with cast iron:Aluminum alloy synchronous wheels are lighter and easier to install and adjust.Cast iron has better high temperature resistance, but aluminum alloy can also meet general use requirements through proper treatment.Cast iron synchronous wheels are usually used in occasions with large transmission power and high speed.Compared with plastics:The strength and hardness of aluminum alloys are much higher than plastics, and they are more suitable for use under high-speed and high-load conditions.Although plastic synchronous wheels are low in cost, their wear resistance and fatigue resistance may not be as good as those of aluminum alloys.
In summary, aluminum alloy as a material for synchronous wheels has significant advantages in terms of lightness, thermal conductivity, plasticity, corrosion resistance, etc., and can meet the requirements of high speed and high load. Therefore, in many applications, aluminum alloy synchronous wheels have become the first choice. Of course, when selecting materials, comprehensive considerations must be made based on specific usage conditions and requirements.
