Mod 0.3 and 0.2 gears



Didel now has a complete set of module 0.3 and module 0.2 gears.

For a module m, the nominal diameter (mid-teeth) of a n-teeth pinion or gear is n • m millimeters.

The pitch (nominal distance between two teeth) is n • 3.14.

The distance between two shafts carrying gears of n1 and n2 teeth is (n1+n1)/2 + x. The clearance x is 0.01 to 0.04mm depending on the precision of the gears and the bores.
