Abstract of the Disclosure A new design for helical gearsets is disclosed in which the new gearsets meet all applicable ratings and standards of the American Gear Manufacturers Association (AGMA), and yet allows very substantial cost savings over prior similar gearsets having an equivalent AGMA rating. The gearsets of the instant invention generally are substantially thinner, and have fewer, but larger, gear teeth than the prior gearsets they replace. A helical gearset of the present invention includes a pinion and a gear, with the pinion and the gear each having a plurality of teeth. Each of these teeth has a helix angle ranging between about 18 degrees and 32 degrees. The pinion and the gear each have a face width and a whole depth, with the pinion having 13 or fewer teeth, and with the pinion and the gear having a face width-to-whole depth ratio of about 4.5 or less. The axial overlap of the gearset ranges between 1.001 and about 1.2.
