hi friends,
in general, the gear specifications i find, the base dia is greater than minor dia. As per definition of involute curve, it is the profile generated when a rolling tangent rolls around the base circle without slipping.If minor circle is less than base circle dia it leads to undercut. Now, my question is why the base dia can't be < minor dia as in splines and avoid undercuts?
