Effects of design parameters on root stresses of thin-rimmed helical internal gears with asymmetric web arrangement in mesh

摘要

This paper presents a study on the effects of design parameters (rim thickness, standard pressure angle, number of teeth, and face width) on root stresses of a meshed thin-rimmed helical internal gear with an asymmetric web arrangement for a planetary gear unit of the automatic transmission of automobile. The tooth deflections of the thin-rimmed helical internal gear with an asymmetric web arrangement of various design parameters due to a concentrated load were calcu- lated by the three-dimensional finite-element method (3D-FEM).
