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