Ease-off modification and tooth contact analysis for near net shape face-gear

Abstract

Abstract An ease-off modification method for face gear by near-net shape forming was proposed to improve transmission performance. Firstly, based on the involute cylindrical gear surface, the completely conjugated tooth surface of the face gear was obtained, and the ease-off surface was constructed using second-order and fourth-order polynomials. Then, the tooth contact analysis for the modified flank is carried out. According to the loaded tooth contact analysis (TCA), the transmission error (TE) and contact path were consistent with the predesigned parameters. The noise experiments confirmed that the meshing performance of the ease-off modification tooth surface is better than that of the ordinary design method, which provides a reference for the topological modification design method for the die tooth surface of face-gear.
