Abstract
The main factor that influences the lifecycle of the double harmonic transmission is the durability of the flexible toothed wheel, which is the most strongly stressed element of the transmission. The complexity of the stress distribution in the flexible toothed wheel depends on many factors, such as: the type of wave generator, the flexible wheel construction shape, the coupling mode of the flexible wheel and the transmission load. In the paper it was studied the stress distribution in the flexible wheel body, as well as the variation of the displacements of the nodes located on certain generatrix of the flexible wheel, by considering three types of mechanical generators with two deformation waves, materialized by: 2 rolls, 2 eccentric discs or cam. The numerical simulation of the flexible wheel was made in the elastic domain using a Finite Element Method with SolidWorks software.
