In this article, a new tip relief profile modification for spur gears is presented. The topography proposed here is a classical linear profile modification with a parabolic fillet (linear-parabolic modification). The parabolic fillet extension is treated as a parameter and its effect investigated. The proposed topography combines advantages from both linear and parabolic tip relief. The evolution from linear to parabolic is discussed in terms of peak-to-peak transmission error. Anomalous contact conditions due to particular tip relief modifications are reported,and maps are obtained in order to find optimum tip relief by taking into account contact condition boundaries.

Abstract
In this article, a new tip relief profile modification for spur gears is presented. The topography proposed here is a classical linear profile modification with a parabolic fillet (linear-parabolic modification). The parabolic fillet extension is treated as a parameter and its effect investigated. The proposed topography combines advantages from both linear and parabolic tip relief. The evolution from linear to parabolic is discussed in terms of peak-to-peak transmission error. Anomalous contact conditions due to particular tip relief modifications are reported,and maps are obtained in order to find optimum tip relief by taking into account contact condition boundaries.File | Dimensione | Formato | |
