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.

This article proposes a new set of configurationsfor the construction of a low cost servo-actuatedshake table with a wide range simulation ability, especially regarding ground motions with strong vertical components up to 3.86g and 1.62m acceleration and stroke respectively. Designing decision and challenges faced during the process are also presented.
