timing belt, V-Belt and Flat Belt Design and Engineering

Design and Engineering Formulas: V-Belt Suppliers. V-belts trump flat belts with their small center distances and high reduction ratios. The preferred center distance is larger than the largest pulley diameter, but less than three times the sum of both pulleys. Optimal speed range is 1,000–7,000 ft/min (300–2,130 m/min).

Flat Belt Design of Transmission Systems

Flat belts are usually made of leather, rubber and fabric. belts made of leather has high coefficient of friction (can transmit more power) thereby ideal for flat belts. To achieve the desired thickness of belt, number of layers of belt material is cemented together. Calculate the design power using the formula

Belt Widths The belt widths are as follows: 18, 24, 30, 36, 42, 48, 54, 60, 72, 84, and 96 inches. The width of the narrower belts may be governed by the size of lumps to be handled. Belts must be wide enough so that any combination of prevailing lumps and finer material does not load the lumps too close to the edge of the conveyor belt.
