At present, the structure of the HP series cone crusher countershaft housing on the market is similar. No matter which mechanism and type (Spring cone crusher, multi-cylinder cone crusher, single-cylinder cone crusher, and etc), the structure and transmission mode of gearbox are basically the same. The body of the HP series cone crusher pinion is made of cast steel, and the cone crusher main shaft in the box is positioned and matched by two rolling bearings. One end of the main shaft is equipped with a motor pulley, which is connected with the motor through a triangle-belt. The other end of the main shaft is equipped with a small gear, which cooperates with the gear of the multi-cylinder cone crusher to convert torque into crushing force. In short, the pinion shaft is a torque transmitter between the motor and the moving cone, and it performs an important function.
