Abstract
This paper presents an analysis of the contact and bending stresses of certain self-aligning automotive spur gear designs under various degrees of misalignment. The resulting deflection and stress fields are studied under quasi-static conditions and compared for different design variants. The proposed solution not only seems to eliminate the necessity to conduct gear tooth crowning, but also makes practical the increase of gear width and a corresponding reduction of the gear module, potentially further benefitting gear dynamics and efficiency.
