Belt-Drive Pulleys

  1. This calculator can be used to analyze two belt driven pulleys. If any of the following three variables are entered the fourth will be determined: High speed pulley diameter (DH), the low speed pulley diameter (DL), the rotational speed of the high speed pulley (NH), or the rotational speed of the low speed pulley (NL), the calculator will determine the fourth variable.

Input 3 of 4 variables to solve for the unknown.
DHHigh Speed Pulley Diameter
