Figure Q1 below shows a gear reducer unit which drive a cement mixer drum at output of this unit and attached to a motor at the input. A 1.5 kW motor with a speed of 9 33 rpm is used as an input source to drive this gear reducer. The gear reducer consists two pairs of spur gears which each pair of them have modules of 1.5 mm for gear set 1 and 2.5 mm for gear set 2. All the spur gears have 20 deg pressure angle.
