A study on modeling and optimization of tooth microgeometry for a helical gear pair

Research on Gear Tooth Longitudinal Modification of Locomotive Traction Gear with Shaft Structure

“…In much literature, the trace modification was completed with traditional 3D modeling software, such as Pro/E, SolidWorks, Romax (Oh et al, 2013) and so on, but the veracity of the model and the accuracy of the modification quantity may be reduced when importing the models into ANSYS. In order to solve this problem, the modified gears would be reconstructed directly in ANSYS.…”

Experiment and Simulation Study on the Gear Tooth Modification of Helical Gear Pair based on Dynamic Performances

“…TE is a deviation of the position of the driven gear from its theoretical one (which it would occupy as defined by the gear ratio if both gears were geometrically perfect and infinitely stiffness) [18]. It is calculated using the micro-geometry of the gears and the misalignments in each loaded condition [19]. When a pair of gears has ideal profiles running with no loading, theoretically, they should mesh with zero TE.…”

Closed-Loop Feedback Flank Errors Correction of Topographic Modification of Helical Gears Based on Form Grinding

“…where V ( 1) 1 is the relative velocity between the grinding wheel and the work gear in coordinate system 1 as the work gear is machining.…”

“…To meet the demand of these kinds of gears, a combination of profile and longitudinal crowning is applied on the tooth flank to increase the gear load capacity and reduce vibrations and noise of the gear drive. Nonetheless, no correction method based on-machine measurement has been proposed for flank topography, even though many authors cite related research based on bevel and cylindrical gears [1][2][3][4][5].…”
