THE STRUCTURE, EFFICIENCY AND KINETOSTATIC OF A NEW TWO STAGE COAXIAL PLANETARY TRAIN

Abstract


Planetary gear systems are widely used in helicopter and aircraft transmissions, automotive automatic gearboxes, many industrial applications and wind power plants as major source of renewable energy. A single stage planetary gear consists of a sun wheel, a ring wheel and the carrier element, which support the planet gears in their rotation around the common symmetry axis of both sun and ring wheels. This arrangement allows a high transmission ratio. In this paper the structure of a new two stage planetary gear with dual path as a speed amplifier is presented. Also the total amplification ratio, the formulas for the global efficiency and the torques on each axis are derived.

Key words: Planetary Gear Train, Dual Path Gear Train, Wheel, Global Efficiency, Torque
