(42S) Solver: Length of a V Belt
Blog Entry:
The following equation relates the length of a V belt, the center to center distance between two pulleys or sheaves: L = 2 * C + 1.57 * (D + d) + (D  d)^2/(4 * C) where: L = length of the V belt, the belt that wraps around two pulleys (or sheaves) C = center to center distance D = diameter of the large pulley/sheave d = diameter of the small pulley/sheave Use the SOLVER function win calling VBELT. LPULLEY: large pulley/sheave diameter SPULLEY: small pulley/sheave diameter Code: LBL "VBELT" Example 1: Large Pulley Diameter = 1 in Small Pulley Diameter = 3/4 in Center to Center Distance = 1.5 in Result: V Belt Length ≈ 5.7579 in Example 2: Large Pulley Diameter = 1 in Small Pulley Diameter = 7/16 in V Belt Length = 6.24 in Result: Center to Center Distance ≈ 1.975 in Source: Gladstone, John "Air Conditioning Testing and Balancing: A Field Practice Manual" Van Nostrand Reinhold Company: New York. 1974 ISBN 0442227035
