Get Price12/04/2017 · If the drive pulley in this example is rotating at a speed of 1000 revolutions per minute, then the speed of the load pulley will be the pulley and belt ratio times the speed of the drive pulley or 1000 rpm times 1/2 which equals 500 rpm. Torque has an inverse relationship to the pulley and belt ratio.

Get PriceAfter calculating Te, it is important to calculate T2 slip (slack side tension required to resist slippage of the belt on the pulley.) The historical method that CEMA provides to calculate T2 slip is as follows: T2 slip = Te x Cw, where Cw is the CEMA wrap factor for a rubber surfaced belt.
