The magnitude of that rotation is torque (τ), expressed in newton-meters (N∙m). The most basic way to calculate torque is to multiply the Newtons of force exerted by the meters of distance from the axis. There's also a rotational version of this formula for 3-dimensional objects that uses the moment of inertia and angular acceleration.

Chain Sprockets • The upper part of the chain is in tension and produces the torque on either sprocket. • The lower part of the chain, or the slack side, exerts no force on either sprocket. • Therefore, the total bending force on the shaft carrying the sprocket is equal to the tension in the tight side of the chain.

Once you determined acceleration torque, to calculate the total torque for your motor add your frictional torque + acceleration torque. Usually, you want to add a safety factor of around 1.5-2 depending on what's available on the market.

Why do I need to calculate chain length? Correct chain length ensures smooth gear shifting and minimizes chain wear. What happens if the chain is too short or too long? If too short, it can stress the derailleur or damage the drivetrain. If too long, it may sag and not shift properly. Do all bicycles use the same chain length formula?

An example of this may be the case where a chain and sprocket assembly are fixed to a nonadjustable motor shaft and required to drive a set of meshing gears. Chain length is a function of the number of teeth of the drive and driven sprockets as well as the center-to-center distance.

of sprocket teeth N1,and N2 as the chain length Lp are available) The pitch number obtained by the chain length formula is, in most cases, only approximate and not in exact agreement with a given inter-shaft distance. Therefore, it will be necessary to calculate the exact distance between the shaft centers based on the required overall length.

The ratio of the force at the pedals to drive force at the road is the gain ratio, which can be calculated more simply as the ratio of road speed to pedal speed, like this:.(1.11 feet /.56 feet) * 50 teeth/20 teeth = 4.95. This calculation is simple and elegant, but our torque calculations give us some additional useful results:
