Introduction of driving wheel
Driving wheels, power transporters of excavators and bulldozers in excavators, because the whole is cast processing, so called "driving wheels", bulldozers because they are separated from several pieces of casting or forging, so called "driving gear block". Driving wheels are usually directly connected with the driving motor, directly transmit the power to the crawler, thus driving the whole chassis forward.
The material of driving wheel is mainly cast, but the driving gear block of high-power bulldozer is mainly forged, so that the product will withstand greater driving force, thus ensuring the quality of the product. No matter what kind of material, the product must pass through casting (forging), mechanical processing, tooth quenching and other processes, and ultimately to the customer.
The driving wheel of excavator is mainly a casting product, the material is generally ZG40Mn, the hardness of the tooth is similar to the bulldozer, HCR46-56, because the wheel is processed as a whole, so the technology is relatively simple, to ensure processing accuracy and dimensional accuracy can be.
