The acting part of the pinion leaves must be produced by the samesized roller as was used for the points of the wheel teeth, but in a differ-ent manner.

The most convenient size for the generating roller for bothwheel and pinion is half the pitch diameter of the pinion. In Fig. 283 isa circle representing the pitch circle of the pinion, with another circlehalf its size rolling within it, and in this case the point described by thepencil would be a straight radial line, which is a suitable form for thepinion. Teeth formed in this way will transmit the motion uniformly at thesame speed as though the pitch circles rolled on each other withoutteeth, and will also meet another important requirement. The actionbetween the teeth will take place almost wholly after the line of centersthat is if the pinion has not less than ten leaves. The difference between.
