Design Problem Design a speed reducer gear box that will take 1.5 kW power from an electric motor rotating at 3000 rpm (clockwise) and deliver it to a machine which operates at 2 different speeds, 1000 rpm (clockwise) and 500 rpm (counter-clockwise). Use Spur Gears with 20° pressure angle and 5mm module. Gear box should be of smallest possible size.

You work for a gearbox company and have been charged with helping to design a geared countershaft for a speed reducing gearbox. The gearbox consists of a compound reverted gear train as shown below and is to be designed for an exact 16:1 speed reduction ratio. The input motor provides 10-horsepower which is carried through the gear train and operates at a speed of 2,000 rpm. You are asked to consider spur gears with a 20° pressure angle and 4...
