Meshing stiffness property and meshing status simulation of harmonic drive under transmission loading

Frontiers of Mechanical Engineering 2022, Volume 17, Issue 2, doi: 10.1007/s11465-022-0674-6

Abstract: The multitooth meshing state of harmonic drive (HD) is an important basic characteristic of its highMeshing force distribution affects the load sharing of the tooth during meshing, and theoretical researchBased on the relationship of meshing forces and circumferential displacements, meshing forces and loadingTheoretical and numerical research show that the flexibility is quite different for varied meshing pointsThe meshing forces and torsional stiffness of the HD are nonlinear with the torsional angle.

Frontiers of Mechanical Engineering 2006, Volume 1, Issue 1,   Pages 90-95 doi: 10.1007/s11465-005-0006-7

Abstract: into contact line analysis.With helix angle chosen as parameter, the criterion for the existence of meshingResults show that there can be four situations for meshing boundary line on the tooth surface of gear, namely, inexistence of meshing boundary line, a unique line, two lines, and two coincident lines.If the helix angle is equal to or slightly smaller than the bigger angle, which makes two meshing boundarylines superpose, a preferable meshing performance is obtained.
