Pulley Belt Calculations - The Engineering MindsetTraduire cette page

These calculations are mainly for existing installations but you could also put it towards your design if you want to calculate what the length needs to be of the belt, as long as you already know the distance between the two pulleys and the size of the pulleys. The second part, the distance between the pulleys, is if you already know what length belt you need and also you know the diameter of ...

12/04/2017 · 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.
