A flat belt drive is to transmit 110 kW at a belt speed of 25 m/s between two pulleys of diameter 250 mm and 400 mm. The centre distance between the pulleys is 1 m. The permissible stress in the belt is 8.5 MN/m2d. Thickness to width ratio of the belt is 0.1 and the density of the belt material is 1100 kg/m3. Then coefficient of friction between the belt and pulleys is 0.3. Determine the minimum required belt width.
What would be the necessary installation force between the pulley bearings and the force when full power is being transmitted?
