MECHANICAL DESIGN – II ASSIGNMENT – 2 A compressor running at 320 rpm is driven by a 50 kW motor running at 1440 rpm through a pair of helical gears. The gears are 20 0 full depth involute in the normal plane and the helix angle is 30 0 . The center distance between the gears is approximately 360 mm. the pinion is to be C30 steel, heat treated and the gear is to be 0.2% carbon steel, untreated. The operation is with medium shock for 8 to 10 hours/day. Design the gear by assuming width of face as 15 times the normal module A motor shaft rotating at 1400rpm has to transmit 20kW power to a shaft with transmission ratio 3.5 to1 .The teeth are 14.5° involute with 20 teeth on pinion. Both pinion and gear are made of SAE 1040 steel. Design the gears by assuming the starting torque to be 50% higher than the running torque. The pinion is surface hardened to 400H B . Design the pinion and ...
