The new sprocket,manufactured by means of this equation,can improve the logistic movement of the .

A comprehensive detection was carried out of the sprockets at both ends of the machine,the bend at the head and the horizontal track,a systematical analysis of the causes of its snaking was done and an adjustment was made.

The new sprocket, manufactured by using of this equation, could improve the logist.
