Calculations and choice of a chain drive<br />
The approximate centre of distance a (mm), the numbers of teeth z1 and z2 ,<br />
as well as the Pitch p (mm) are to be chosen, before the calculation of the<br />
number of links and centre distance.<br />

If possible, the calculated number of links should be rounded up to even<br />
numbers, so no cranked link is required,(Breaking load is 20% less).<br />
With this number of links X, the exact centre distance can be calculated.<br />
