How to assembly sprocket and chain:

2, The center line of the driving sprocket and the driven sprocket shall coincide, and the deviation shall not be greater than 2/1000 of the center distance of the two sprockets.
3, When the working edge of the chain is tightened, the sag f (see the figure below) of the non working edge should meet the design requirements. When there is no regulation and the angle between the chain and the horizontal line α When it is less than 60 °, 1% - 4% of the center distance L of the two sprockets can be used 5% adjustment.
