For a belt to transmit full power a minimum of 6 teeth must be in mesh on each pulley. The number of teeth in mesh can determined from the following formula: Number Teeth in Mesh (TIM)= Z 1[0.5 - (Z 2- Z 1)p] 18.85A The Design Power Pd must be multiplied by factor f5 taken from table 2a. b.

Allowing the user to quickly adjust their original assumptions based on the configurations displayed. This feature is a must have when your variables are constrained by: Fixed shaft center to center distances Ratio Support structure interferences Timing belt pulley size limitations To use the calculator click here.

You can calculate the Belt length if timing-pulley diameter and center to center distance between the

Now you are ready! You now have the information you need to make an informed decision for your next custom timing pulley project.

Nov 17,  · The simplest way to find the ratio of the required pulley is to divide the driven component (pump) by RPM. For example, if the pump RPM is 1070 for full output, while the motor is 1750 RPM, the ratio of the required pulley would be (pump RPM) divided by the motor RPM, or: 1070 / 1750 = 0.611

The speed ratio is defined as the ratio of the large to small pulley size and can be calculated simply by dividing the number of teeth in the
