- Abstract
The paper contains results of the research and development of precessional transmissions on structural synthesis, kinematics and the design of AB and AD gears with the gearings B ACX -R,B ACX-CV,D ACX -CV,D ACV -CV,B ACX-R . There is presented the analysis of the technical solutions regarding the increase of the bearing capacity of AB and AD gears and of the mechanical efficiency of the transmissions by using different geometries of the teeth contact with convex/concave profiles with the small difference of the radii of curvature and with reduced friction slip between the flanks. The concepts of . con Gr s and . disc Gr s spatial tumbling-rolling processes of generation of teeth with non-standard variable profiles are described, the fields of application of the precessional power and kinematic transmissions are described. Keywords: Precessional transmissions, bearing capacity and mechanical efficiency, concave-concave contact, convex/concave profiles, teeth generation by spatial tumblingrolling.
