Gear mesh stiffness plays a very important role in gear dynamics and it varies in the
presence of gear fault such as crack. The measurement of stress intensity factor can lead to …

Gear transmission is a major form of power transmission, of which the reliability greatly
affects the life of many mechanical devices. Gears have two main failure modes, namely …

In this paper, we propose segmentation-aided digital image correlation (SA-DIC) for
measuring the deformation near the interface between two contact bodies. Conventional …

Abstract The Direct Gear Design® approach is one of the many gear designing methods
available to improve load carrying capacity of the gear pairs. For customized gear pairs, the …

An accurate calculation of the maximum tooth root stress (TRS) and critical section location
(CSL) provides a basis for predicting and improving gear performance. The irregular profile …

Optimising the hob used to manufacture gears is an attractive approach for minimizing the
gear tooth root stress. However, currently available approaches often require modifying the …

Maximum fillet and contact stresses of asymmetric normal contact ratio spur gears designed
by direct design method are evaluated based on the load sharing ratio, using finite element …

Free-Form-Gear (FFG) is a recently published title for a gear that has a curved path of
contact and offers contact between a convex addendum and a concave dedendum during …

In this paper, a comprehensive methodology for calculating load sharing in multiple tooth
contact is presented based on the experimental stress‐optical method of caustics. The …

Direct gear design method is one of the most effective gear design approaches, which
provides the high performance gears without concern for any predefined tooling parameters …
