ABSTRACT:
A gear transmission with a variable pressure angle has the following meshing geometry: a contact ratio greater than one, height of the addendum of gear and pinion teeth being a function of its module "m" determined by the relationship m<h.sub.g <1.8, a height of a tooth root of the pinion being limited by the value of a profile angle .alpha..sub.z equal to .alpha..sub.z .gtoreq.8.degree., a height of a tooth root of the gear determined by the relationship m<H.sub.s <1.8 m and increased by the value of radial clearance and a height of an addendum of the greater teeth equal to the height of the tooth root of gear and pinion, decreased by the value of radial clearance. The teeth are made with racks of involute profile having cutting edges and their constant base circle determined from apparent number of teeth and a constant pressure angle.
