Load torque calculation for rotary index tables uses the same formulas as a belt drive, but it requires a slightly different thought process to determine the necessary variables.In this case, friction occurs at points where the ball rollers (support bearings) and the table make contact, so radius (r) will be the distance from the center of the motor shaft to the contact point between the table

When sizing to the motor (loading parameters at the drive pulley) you are required to calculate peak power and RPM, peak torque and RPM, peak peripheral force and RPM and reduction ratio. Factors such as whether or not there is belt back-bending also must be considered.

Determine the drive mechanism First, determine the drive mechanism. Representative drive mechanisms include simple body of rotation, ball screw, belt pulley, and rack-and-pinion. Along with the type of drive mechanism, you must also determine the dimensions, mass and friction coefficient etc. that are required for the load calculation.

Gears are useful for multiplying or dividing torque, whether the gears mesh directly or through a belt or chain; the ratio of the size of the gears determines whether they increase or decrease torque. To calculate gear ratios and the effect they have on torque, you need the size of each gear and the torque acting on the first gear, which
