Feasibility analysis of using a two-stage nutation drive as joint reducer for industrial robots
Journal of Mechanical Science and Technology, 2019Nutation drive claims the advantages of high load capacity, large transmission ratio, desirable stability, low noise, and compact volume, which makes it an excellent alternative to typical joint reducers used in industrial robots. This paper proposes a novel two-stage nutation drive as a joint reducer for the industrial robot.

Mathematical Model and 3D Modeling of Involute Spiral Bevel Gears for Nutation Drive
Advanced Materials Research, 2013The mathematical model and 3D modeling of involute spiral bevel gears for nutation drive are considered. The basic tooth profile of involute is composed of involute curve and dedendum transition curve, and the equations have been established. The mathematical model of crown gear with involute profile is obtained, and then the mathematical models of the
