Question

It is required to select a V-belt drive for transmitting power from 5 kW normal torque motor, whichruns at 1440 rpm to a light duty compressor running at 970 rpm. The compressor runs for 24 hoursper day. Space is available for a centre distance of about 500 mm. Assume that the pitch diameterof the driving pulley is 150 mm. Determine the following: i.Compute design power ii.Select the belt section iii. Determine pitch diameter of the driven pulley ivSpecify the belt length V. Compute the actual center distance that would result. vi.Compute the rated power, considering corrections for speed ratio, belt length, and angle of wrap
