The impact of the structural form on the stress distribution in a flexspline of a hermetic harmonic drive

Jacek Pacana
This paper presents a comparative analysis with different models of the flexspline for a harmonic hermetic drive. The flexspline is 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 MES method in ADINA. The work presents stress diagrams in longitudinal intersections for susceptible wheels of different shapes, for direct comparison.
Suggested changes in construction of flexspline will increase the durability of the welded hermetic gear.
Keywords: Flexspline, Harmonic drive, Stress analysis, Finite Element Method (FEM)
