Abstract: A new silk-hat type of harmonic drive device (HDD) with arc flexspline (FS) structure is developed. Loaded gear contact analysis (LGCA) and stress calculations are made for it with three-dimensional, finite element method (3D-FEM). Basic performances and strengths tests are also made. It is found that the new structure almost has the same performances and strength as the old one.

Abstract: This paper is a study on loaded gear contact analyses (LGCA) and strength calculations of trochoidal gear reducers (TGR). A two-dimensional finite element method (2D-FEM) is used to conduct LGCA and strength calculations of the TGR. Effects of machining errors (ME) and tooth modifications (TM) on tooth load and pin load distributions of the TGR are also discussed.
