Many customers in the purchase of pulley, the most headache is the installation problem. Many people do not know the way to install the cone belt pulley after changing the original national standard belt pulley. Today, we will answer how the cone pulley is installed.
When the pulley and coupling of the motor are disassembled, the position mark is done between the pulley or the coupling and the shaft, the fixed screw and the pin are tightened, and then the pull gear is slowly pulled out. If you can't pull it out, pour some kerosene into the hole and pull it. If still can not be pulled out, the quick fire can be heated around the pulley or coupling quickly, and the shaft is wrapped with wet cloth, and the cold water is constantly poured in order to prevent the heat from passing into the motor.
When assembling, a fine iron sand cloth is used to smooth the shaft sand of the shaft, pulley or coupling, and the pulley or coupling is placed on the shaft on the key slot, and the key is placed on the key with the cooked iron or hard wood block, and the key is gently knocked into the slot. The key should be tight in the slot. Too tight or too loose will hurt the key and hurt the groove. Too loose will make the belt slip or vibrate.
