The importance of sprocket tooth width:
Because it is not restricted by the chain. The sprocket can be made to any width. As the tooth width of the sprocket increases, the wear of the sprocket sprocket is reduced, the life is increased, and the transmission power is increased.
However, the pin shaft also grows with the increase of the tooth width of the sprocket. An excessively long pin shaft will reduce its stiffness, which will easily cause fatigue damage to the pin shaft and rollers of the chain disc.
The diameter is small because the number of sprocket teeth of the sprocket reducer is small. Often need to be machined into one with the sprocket shaft.
In order to extend the service life of the shaft, it is generally recommended that the tooth width of the sprocket reducer sprocket is twice the standard sprocket tooth width.
