This paper presents a comparative analysis with different models of the flexspline for a harmonic hermetic drive. The flexspline is a thin-walled construction, deforming during work, so its design is a very complicated process. The paper contains a strength analysis for some selected models of this gear. Calculations were performed using the finite element method (FEM) in ADINA. The work presents stress diagrams in longitudinal intersections for susceptible wheels of different shapes for direct comparison. Suggested changes in construction of the flexspline will increase durability of a welded hermetic gear.
