A-V belt is to transmit 20 kW from a 250 mm pitch diameter sheave to a 900 mm diameter pulley. The center distance between the two shafts is 1000 mm. The groove angle is 40' and the coefficient of friction for the belt and sheave is 0.2 and the coefficient of friction between the belt and flat pulley is 0.2. The cross-section of the belt is 40 mm wide at the top, 20 mm wide at the bottom and 25...
Determine the number of V-belts required to transmit a power of 60 kW at 750 rpm from an electric motor to a compressor shaft at 300 rpm. The larger pulley diameter is 1500 mm. The centre distance is 1650 mm, and overload factor is to be taken as 1.5. A belt with cross- sectional area of 350 mm², density of 1000 kg/m and having an allowable tensile strength of 2 MPa is available for use. The coefficient of friction between...

A single V-belt drive system is powered by an electric motor with a speed of 2691 rpm and transmits a power 11 kW. The driving pulley is connected to the driven pulley by a single V-belt of angle 18 degrees and a unit weight of 2.18 N/m. The angle of wraps between the belt and pulley is approximately 175 degrees. The driven shaft is attached to a cylindrical pulley of 101 mm and runs at a speed of 1221 rpm....
