ABSTRACT:
As the sprocket teeth wear, the pitch of the sprocket teeth decreases. As the chain wears, the pitch of the chain increases, this causes the rate of wear to increase. A sprocket after being in use for 1000 hours may have four times the wear as it had after 500 hours use. This invention, a sprocket with simultaneous adjustable pitch of the teeth, will keep the wear rate to the minimum.
