TL;DR: In this paper, a comprehensive methodology for calculating load sharing in Roller-bearing contact was presented based on the experimental stress-optical method of caustics and photoelasticity.

TL;DR: In this paper, the concept of non-dimensional gear teeth is introduced to reduce the total number of design variables by interpolation of tabulated values, which were calculated previously by applying the BEM on nondimensional models corresponding to different combinations of the design parameters.

TL;DR: In this paper, the analytical models of the operation of rolling element bearings are used for the better utilization of precision maintenance in practice, since it could lead to the correction of the cause of each failure and thus the bearing will not fail again for the same reason.

TL;DR: In this article, the authors propose a method of discretizing the gear tooth flank in involute segments for the determination of conjugate gear tooth profiles, which is faster than the standard theory of gearing and is particularly useful in problems requiring iterative calculations of the tooth geometry such as gear optimization.

TL;DR: 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, which is applied to a set of poly-methyl-methacrylate gears at various meshing positions covering a complete meshing cycle, including single and multiple gear tooth contact.
