Pulley, belonging to the hub type parts, generally relative lying relative size is relatively large, manufacturing process in general to casting, forging-based.
The pulley belongs to an important part of the mechanical transmission system, widely used in the fan industry air conditioning, air compressor, locomotive, aircraft and other industrial equipment such as pumps, fans, high power and higher power internal combustion engines, compressors, gas turbines and other industrial equipment with higher power and higher speed. When we choose for machinery, we first have to understand the rated power of machinery is how much, speed is how much, diameter is how much, so as to avoid communication with us and pulley manufacturers to create unnecessary trouble, tapered pulley using domestic high-end material (HT250), and pulley products must go through the dynamic balance test before leaving the factory, In this way, the pulley can play a smooth and non-sliding drive during high-speed operation.
Of course, there are some special circumstances, according to the needs of mechanical equipment, such as transmission torque size, transmission accuracy and so on, in order to determine the appropriate type of pulley can be determined.
