1.SPROCKETS
The sprockets are connected to the shaft by one of several available methods. However, connection by a keyway and grub screw is common. Sprockets give the same drive speed, increased drive speed or decreased drive speed. This is achieved by varying the number of teeth in each sprocket. The same number of teeth gives the same speed to the driven shaft. If the driven sprockets teeth are less, then the speed increases and if the driven sprockets teeth are more, this will decrease the speed of the driven shaft.
