Belt drives have been used for more than 200 years for conveyance of materials and transmission of load. There are three basic types of power transmission belts – flat belts, V-belts, and synchronous belts. Flat belts have a rectangular cross section and are efficient due to low bending losses, low creep, and high modulus of elasticity of traction layers. V-belts are trapezoidal in cross section and are used in industrial applications because of their relative low cost, ease of installation ... Read more
