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. The gear shift mechanism is not the part of the design A 2-speed double-reduction speed reducer is shown in the...
