Description

Technical Field

[0001] The utility model relates to the technical field of sprocket transmission, in particular to a chain sprocket transmission pre-tightening component. Background Art

[0002] A sprocket chain is a transmission method that transmits the motion and power of a driving sprocket with a special tooth shape to a driven sprocket with a special tooth shape through a chain. After the chain is installed on the two sprockets, the chain tightness needs to be adjusted through the tensioner to ensure stable transmission. At the same time, the sprocket chain needs to be oiled during transmission.
