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.

Most bearings in the 6000, 6200 and 6300 series up to 60 mm bore also can be made available in stainless steel (AISI 440C material).
Timken stainless steel bearing numbers are designated using the "H" suffix (e.g. 6203H-2RS).
