The roller chain is a kind of chain for transmitting mechanical power

and widely used in industrial and agricultural machinery.Taking 08 Btype short pitch precision roller chain as example

the most common ways of roller chain drive are analyzed

and the simulation analysis of motion characteristics of

the transmission efficiency and the dynamic load of the chain drive are carried out respectively.The results of simulation verify the basic characteristics of chain drive

the dynamic load size and transmission efficiency are predicted

the results are consistent with the theoretical analysis.The basis for the selection and application of chain drive in engineering is provided by this method

the basis for the design and type selection of other roller chain is also provided.
