 It is called sprocket in crawler crane and excavator , because the main process is forging . It is called segment in bulldozer , because the main process is casting.


General speaking, sprocket is connecting with diving motor, transmit power to the track directly, so as to drive the chassis parts turning. The main process is forging, but the main process is casting for segment in high-power. The segment can withstand greater driving force to make sure the high quality. However any material , the product all must have these processes , such as casting, machining, quenching of the gear , then hand over to customer use.


The main process of sprocket is forging in crawler crane, the material is 35SiMn, the hardness of gear quenching is similar with bulldozers, HCR46-56, the main process is simple , the key process is the precision of machining.
