A propeller shaft C having a diameter of 75 mm is mounted on two bearings B1 and B2 and is driven by a 70 kW motor running at 1200 rpm in a clockwise direction as shown in Figure Q.1. Gear 1 is the driving gear with 17 teeth, idler gear 2 has 23 teeth and the output gear 3 has 46 teeth. All gears are helical having a normal pressure angle of 20°, a helix angle of 30° and a normal module of 4 33. (a) Determine the forces on gear 3. (b) Determine the resultant loads at bearings B1 and B2. Select suitable ball bearings for supporting shaft C at B1 and B2 using Datasheet Q1 (c) for a required bearing life of 8000 hours.
