The Profile Calculation and the Best Fillet of Powder Metallurgical Gears
this paper researched the profile calculation and the best fillet of powder metallurgical gears. Different from the ordinary gears, we must research the locals of the cutter to make the die of the powder metallurgical gears. And it is possible to revise the fillet in order to increase the bending strength of the powder metallurgical gears.
