...in radial flank gearing, for the radial flanks of B require that the faces of A shall be epicycloids generated by a circle whose diameter is equal to the radius of B, consequently, this face will only work with awheel of the diameter of B. Similar remarks apply of...

...straight instead of curved flanks, the lines being radial. This is quite correct, because a hypocycloid generated by a circle whose diameter is equal to the radius of the pitch circle inside which it rolls is a straight line, Fig. 12. The generating circle should not be made larger...
