Generation, TCA and Stress Analysis of the Face Gear Drive with a Tapered Involute Pinion

doi:10.3901/JME.2020.07.086

Abstract

Abstract: For the purpose of backlash adjusting in different power flow branches of the concentric split-torque system, which affect the distribution of the load between the input pinons or the idlers, a new kind of face gear drive mating with a tapered involute pinion is investigated. The profile modified tooth surface of the tapered involute pinion and the face gear is derived. The limiting conditions of the face gear is determined. Tooth contact analysis (TCA) and stress analysis are performed in order to evaluate the performance of the presented face gear drive. The results show that: the half cone angle of the face gear drive should be controlled with the tooth strength of the gear into consideration. The face gear drive is less sensitive to the misalignments. The edge contact can be avoided with a profile modified pinion or a profile modified face gear. Furthermore, the backlash adjusting is achieved by the axial movement of the pinion. And it has little influence on the tooth contact pattern of the face gear drive. This kind of face gear drive can be applied to the situations where the backlash adjusting is required, such as the concentric split-torque system.
