Theory of Mechanism and Machine I

In an epicyclic gear of the 'sun and planet' type shown in figure, the pitch circle diameter of the internally toothed ring is to be 224 mm and the module 4 mm. When ring D is stationary, the spider A, which carries three planet wheels C of equal size, is to make one revolution in the same sense as the sunwheel B for every five revolutions of the driving spindle carrying the sunwheel B. Determine revolution of planet wheel C. Determine suitable numbers of teeth for all the wheels.
