In an epicyclic gear of the sun and planet type shown in figures given below, the pitch circle diameter of the internally toothed ring is 252 mm and the module is 3.5 mm, the ring D is stationary. The spider A which carries three-planet wheel P of equal size, is to make one revolution in the same sense as the sun wheel S for every five revolutions on the driving spindle carrying the sun wheels S.
