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 researchTo calculate the spatial distributed meshing forces and loading backlashes along the axial direction,Based on the relationship of meshing forces and circumferential displacements, meshing forces and loadingThe meshing forces and torsional stiffness of the HD are nonlinear with the torsional angle.

Gear fault diagnosis using gear meshing stiffness identified by gearbox housing vibration signals

Frontiers of Mechanical Engineering 2022, Volume 17, Issue 4, doi: 10.1007/s11465-022-0713-3

Abstract: Therefore, using gearbox housing vibration signal to identify gear meshing excitation signal is of greatThis paper establishes an analytical mathematical description of the whole transfer process from gear meshingThe gear meshing stiffness (GMS) identification approach is proposed by using housing vibration signalsare discovered in the identified GMS spectra, and the results also validate the rationality of using meshingstiffness to describe the actual gear meshing process.

Effects of Boundary Condition and Helix Angle on Meshing Performance of TI Worm Gearing

SUN Yue-hai, DUAN Lu-qian, WANG Shu-ren, ZHANG Ce

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.
