Q2: A speed reducer unit is to be designed for an input of 1.1 kW with a transmission ratio 27. The speed of the hardened steel worm is 1440 r.p.m. The worm wheel is to be made of phosphor bronze. The tooth form is to be 20° involute. Given data: the centre distance (x) = 100 mm. Draw complete construction of the system showing all missing parts, i.e. keys, bearings...etc, with necessary mountings and fixations. (Put the main dimension). Assume suitable missing dimensions or data if any.
