Abstract

The invention relates to the gears and may be used in the reduction gears in the gearing mechanisms. The aim of the invention: oscillations and units dynamical leading decreasing. The precessional gear comprises a body 1 in which are dislocated the central wheels 2 and 3 and double corona satellite 6, placed on the flat oblique crank 7, the oblique crank space axe 7 is arranged relatively to the driving shaft 8 at an angle γ which is greater with of the cranc axe 7 θ inclination angle.Such a crank space enables the complete balancing thereof.
