Abstract
The traction drives requires initial tension. Let us imagine such kind of epicyclic drive or harmonic drive. In both cases the annular wheel is made of spring steel and its load is bending. The stiffness of the ring is large enough to produce the required normal force between the annular and the planetary wheels or between the ring and the flexible, cup shaped wheel. The transmission ratio depends on the ratio of planetary and sun wheel in the planetary drive, or the difference between the circumferences of ring wheel and the cup shaped wave wheel on the harmonic drive. Both the deflection of ring wheel and the number of planetary wheels or the number of deflection wave increase the load carrying capacity and decrease the bending moment. The problem of deflection can be managed by differential equation or any kind of energy method. The analysis of equivalence of the outcomes closes the paper.
