The Length of a Belt calculator computes the length of a belt that goes around two pulleys Belt length around two pulleys. based on the pulley diameters (DD and Dd) and the distance between the axles (L).
INSTRUCTIONS: Choose units and enter the following:
Belt Length (BL): The calculator return the belt length (BL) in meters. However, this can be automatically converted to other length units via the pull-down menu.
BL = (DD+Dd)•π/2 +(L•2)+ ( (DD-Dd)² / (L•4) )
