Select a roller chain drive to transmit 7,000 W from a driveshaft to a driven shaft of a fruit conveyor. The drive shaft is 20mm in diameter and operates at 1200 rpm. The driven shaft is also16 mm in diameter and must operate between 300 and 350 rpm. Shaftcenters, once established, are fixed and by initial calculationsmust be approximately 500 mm. The load on the drive shaft is unevenand presents “peaks” which places it in the heavy shock loadcategory. The input power is supplied by an electric motor.
