V-belts are used as mechanical links between two or more rotating pulleys. The length of the V-belt is dependent on the size of the pulleys and the distance between them, and can be calculated with a simple formula.
-
Measure pulley center distance
Measure the distance between the centers of the two pulleys. This is denoted by C in the formula.
-
Calculate pulley diameters
Measure the diameters of the small pulley, denoted by D1, and the large pulley, D2.
-
Use the formula or enter measurements into online calculator
Using the formula “L= 2C + (D2-D1)/2 + (D2-D1)2/4C,” calculate length of the V-belt, where L denotes the length. The result can also be determined by entering the measurements into an online calculator provided by Baum Hydraulics Corp.
