Drive calculation for double V-belts differ from the drive calculations of two pulley drives. The effective lengths, rotational speeds, transmission ratios 

V-belt tensioning For the initial installation of optibelt RED POWER 3 V-belts, the same methods are used as for standard Optibelt V-belts. The tension values are to be calculated on the same basis or to be taken from the table on page 147. Once correctly tensioned optibelt RED POWER 3 V-belts need no re-tensioning. Application areas

1. rolling resistances of the idlers 2. flexing resistance of the belt 3. flexing resistances of the bulk material 4. acceleration resistance and frictional resistance between material handled and belt 5. chute frictional resistance 6. scraper resistance 7. deflection resistance due to belt bending 8. gradient resistance of conveyed material W S

V belt have short centre distance consume much higher space for which results in compact construction operation. COMPARISON OF FLAT BELT DRIVE AND V BELT DRIVE FLAT BELT DRIVE V BELT DRIVE 7. Flat belt produce more noise than V belts. 8. Power transmitting capacity of flat belt drive is low. 9.

A new formula which can figure out the life of the V-belt with different reliability is presented, and a calculating example by the new method has been 

Calculate the maximum power transmitted by the belt and the corresponding belt velocity. Neglect power losses. (. ) The belt tension is maximum when v=0.Hence.
