Generally speaking, one synchronous belt had to work together with two synchronous belt wheels at the same time, but Synchronous belt manufacturer said the main role of these two synchronous belt wheels is different, for example, one of the synchronous belt wheel is used as the driving wheel, which needed connect with the main axle of engine motor part, and another synchronous belt wheel is used as the engaged wheel, which had to contact with the power output axle. To these total teeth number of these two synchronous belt wheels,Synchronous belt manufacturer said this teeth number had to confirmed on the transmission rate of the actual design of transmission equipment.

　　Professional Synchronous belt manufacturer said the rotation rate of synchronous belt transmission equipment is equal to large synchronous belt teeth number to divide small synchronous belt wheel teeth number, so when confirm the total teeth number of synchronous belt wheel, but with the limiting of the smallest bending radial diameter of each specification synchronous belt, the final total teeth number of small synchronous belt has the certain limiting on the depend of synchronous belt engineering parameters too.
