One of the main functions of the scraper conveyor on the fully mechanized mining face is to transport the coal cut by the shearer, which is realized by the chain installed on the scraper conveyor

The distribution of transmission ratio is one of the important problems in the design of gear transmission chain. Whether the distribution of the transmission ratio is reasonable will affect the structural layout of the entire transmission chain and its working performance, so the distribution of the transmission ratio must be carried out reasonably according to the requirements of use in the design

The chain speed and the driven sprocket angular speed change periodically, resulting in an additional dynamic load
