The principle and dynamic display of sprocket chain drive
The ISO Sprocket shaft teeth are arcuate on both sides to facilitate the entry and exit of the links. The sprocket teeth should have sufficient contact strength and wear resistance, so the tooth surface is often heat treated. The small sprocket has more meshing times than the large Finished Bore Sprocket, and the impact force is also large, so the material used should generally be superior to the large ASA Sprocket
Commonly used sprocket materials are carbon steel (such as Q235, Q275, 45, ZG310-570, etc.), gray cast iron (such as HT200). The important Taper lock Sprocket can be made of alloy steel.
Advantages of chain drive: Compared with belt drive, no elastic sliding and slipping phenomenon, accurate average transmission ratio, reliable operation and high efficiency; large transmission power, strong overload capability, small transmission size under the same working conditions; required tension Small, the pressure on the shaft is small; it can work in harsh environments such as high temperature, humidity, dust, pollution.
Disadvantages of chain drive: It can only be used for transmission between two parallel shafts; high cost, easy to wear, easy to stretch, poor transmission stability, additional dynamic load, vibration, shock and noise during operation, not suitable for rapid reverse In the transmission
