3. (a) Identify each of the seals as shown in Figure Q3 (a) and describe typical working conditions such as temperature, pressure and speed, in which each identified seal is suited. [6 marks] i) ii) iii) Pump Housing w Posting Shu Figure Q3 (a) (b) Figure Q3 (b) shows a planetary gear train. Tooth numbers for the gear train are N2 = 14, N3 = 18, and N4 = 14. The input shaft a that coupled to the gear 2 rotates clockwise at 400 rev/min and output shaft is coupled to the arm 6. Figure Q3 (6) i) Determine the tooth number of the internal gear 5. [2 marks]
ii) Determine the speed and rotation direction of output shaft b if the gear 5 is fixed [2 marks] iii) Calculate the centre-to-centre distance between gears 2 and 4 if the module of gears is 3 mm. [2 marks]
