Planetary Gear on Basis of Diplane Meshing with Intermediate Bodies

Aliev F.R., Lazurkevich A.V., An I.


The design is considered and the technique is proposed for geometrical calculation and the kinematic analysis of one of kinds of planetary gears with meshing of intermediate bodies-balls with the improved characteristics: high efficiency due to reduction of losses by friction, the increased load ability thanks to multi-paired relationship of gearing, compactness, etc. The planetary gear contains two sun gearwheels, the carrier, the satellite and two groups of intermediate bodies-balls which are contacted with surfaces of teeth arranged on the face surfaces of sun gearwheels and the satellite turned to each other. At the same time each group of intermediate bodies-balls are separately positioned and united with the help of the separator representing a disk with openings for balls. To eliminate the loading on a separator of the meshing axis, in each meshing couple made of a solar wheel, the satellite and the separator with intermediate bodies-balls are combined. The numerical example of geometrical and kinematic calculations of the gear is given. It is shown that the corresponding selection of parameters allows for reducing almost to zero the speed of sliding of balls with respect to tooth surfaces.
