Evaluation of Tooth Contact Stress With Tooth Flank Film Elements (Comparison of Evaluation With Measurement)

A new finite element analysis for meshing gear pair has been developed with a new element called “tooth flank film element.” The new element is a phantom element put on a tooth flank without any thickness, and enables boundary conditions for a contact problem in meshing teeth to be easily dealt with. In the present paper, contact stresses between tooth flanks of mating gear pair calculated with the proposed finite element method are compared with stresses measured with pressure measurement films. As a result, the proposed method was confirmed to be useful for evaluation of contact stress.
