Belt pulley is a kind of hub part, and its relative size is generally large. The manufacturing process is generally based on casting and forging. Generally, cast iron is used, and cast steel with good casting performance is rarely used; Generally, the small size can be designed as forging and the material is steel. Belt pulley is mainly used for long-distance transmission of power, such as mining machinery, machining equipment, textile machinery, packaging machinery, lathe, forging machine and so on. What are the advantages and disadvantages of the pulley?
The advantages of pulley drive are
1. The belt pulley transmits kinetic energy to mitigate the impact of load.
2. The belt pulley drives smoothly, with low noise and vibration.
3. The structure of belt pulley transmission is simple and easy to adjust.
4. Pulley drive is not as strict as meshing drive for the manufacturing and installation accuracy of pulley.
5. The belt pulley transmission has the function of overload protection.
6. The adjustment range of the center distance between the two shafts driven by the belt pulley is large.
The disadvantages of belt drive are
1. The belt pulley transmission has elastic sliding and slipping, the transmission efficiency is low and the accurate transmission ratio cannot be maintained;
2. When the belt pulley transmission transmits the same large circumferential force, the outline size and the pressure on the shaft are larger than that of the meshing transmission;
3. The service life of pulley drive belt is short.
