1. Different composition characteristics
1. Sleeve chain: There are no rollers in the component parts, and the surface of the sleeve is in direct contact with the sprocket teeth when meshing.
2. Roller chain: A series of short cylindrical rollers linked together, driven by a gear called a sprocket.
Two, different characteristics
1. Bushing chain: When the bushing chain is running at high speed, lubricating oil is more likely to enter the gap between the bushing and the pin shaft, thereby improving the wear resistance of the chain.
2. Roller chain: Compared with belt transmission, it has no elastic sliding, can maintain an accurate average transmission ratio, and has high transmission efficiency; the chain does not require a large tension force, so the load on the shaft and bearing is small; it will not Slip, reliable transmission, strong overload capacity, can work well under low speed and heavy load.
3. Different pin diameters
For bush chains with the same pitch, the diameter of the pin shaft is larger than that of the roller chain, so that during the transmission process, the contact area between the pin shaft and the inner wall of the bush is large, and the specific pressure generated is small, so the bush chain is more suitable. It is suitable for the harsh working environment of diesel engines with heavy loads.
