a: The pitch and number of rows of the chain: The larger the pitch, the greater the power that can be transmitted, but the unevenness of motion, dynamic load, and noise also increase accordingly. Therefore, under the condition of meeting the load-carrying capacity, small-pitch chains should be used as much as possible, and small-pitch multi-row chains can be used for high-speed and heavy loads;
b: Number of sprocket teeth: The number of teeth should not be too few or too many. Too few teeth will intensify the unevenness of the movement. Too much pitch growth caused by wear will cause the contact point between the roller and the sprocket teeth to move toward the top of the sprocket teeth. Movement, which in turn causes the transmission to easily jump teeth and break off the chain, shortening the service life of the chain. In order to achieve uniform wear, the number of teeth is best to be an odd number that is a prime number to the number of links.
c: Center distance and number of chain links: If the center distance is too small, the number of teeth meshing between the chain and the small wheel is small. If the center distance is large, the slack edge will sag too much, which will easily cause chain vibration during transmission. Generally, the number of chain links should be an even number.
