The classification of wheel set forgings can be carried out from multiple perspectives. The following are some of the main classification methods: First, classification by material. The commonly used materials for wheel set forgings include but are not limited to the following: \ n - 60# : It has excellent comprehensive mechanical properties and wear resistance, and is one of the common materials in wheel forgings. 65Mn: It features high hardness and wear resistance, making it suitable for wheel forgings that require high hardness and wear resistance. 42CrMo: It features high strength and toughness, making it suitable for wheel forgings under heavy loads and harsh working conditions. 45# and 40Cr: These materials are also frequently used in the manufacturing of wheel forgings and each has its own unique mechanical properties.
Second, Classification by Wheel Nature \ n - Single Flange: The edge of the wheel is a single structure, suitable for specific working environments and requirements. Double flanges: The wheel edges have a double structure and are typically used in situations where higher stability and load-bearing capacity are required. Flangeless: The wheel edges have no special structure and are suitable for some special working environments and requirements. Third,Classification by Driving Mode \ n \ n - Driving wheels: Wheels directly driven by a power source, responsible for providing the power for forward movement. Driven wheel: A wheel that is not directly driven by a power source and usually rotates along with the rotation of the driving wheel. The driving wheel and the driven wheel: These two names are similar to those of the active wheel and the driven wheel, but they may vary depending on the specific application scenario. Fourth, Classification by Processing Temperature \ nDuring the processing of wheel set forgings, based on the temperature of the billet during processing, they can be classified into cold forging, warm forging and hot forging. Cold forging is generally processed at room temperature, while hot forging is processed at a recrystallization temperature higher than that of the metal billet. Different processing temperatures will affect the mechanical properties and surface quality of forgings. Fifth, Classification by Structure \ nThe structural complexity of wheel set forgings varies. According to the differences in geometric shape structures, they can be classified into different categories. For instance, some wheel forgings may have complex curved surfaces and branch structures, which require special forging processes and die designs. In conclusion, there are various classification methods for wheel set forgings, and the specific classification depends on multiple factors such as material, wheel properties, drive mode, processing temperature, and structure. In practical applications, it is necessary to select the appropriate wheel set forgings based on the specific working environment and requirements.
