The four helical gears shown in Figure P16.16 have a module in the normal plane of 4 mm and a pressure angle in the normal plane of 0.35 rad. The motor shaft rotates 550 rpm and transmits 20 kW. Other data are on the drawing.
Â
(a) What is the speed ratio between the motor (input) and output shafts?
(b) Determine all force components that the 20-tooth pinion applies to the 50-tooth gear. Make a sketch showing these forces applied to the gear.
(c) The same as part (b), except for the force components that the 50-tooth gear exerts on the 25-tooth pinion.
