“…One of his recent studies on analyses of thin-rimmed spur gear with inclined webs founds that the web location and the web angle of the thinrimmed gears have a substantial effect on the root bending stresses, the tooth contact stresses, and the joint stresses. His findings were aligned with the calculation from Miyachika [31], F Cura [19] and Opalic [32] that also take consideration on the effect of rim thickness and web arrangements on tooth bending strength of thin-rimmed spur gears.…”

Abstract. Gear tends to play a very vital role in all industries. As other mechanical systems, it is subject to design parameter, installation errors, method of manufacture and load uncertainties arising from randomness. Before engineers could design an efficient and safe gear, it is importance to understand how gear can fail is much needed. This article reviews the methodology used to investigate bending strength of spur gear; Finite Element Method (FEM), Numerical Calculation and Investigational Techniques were usually carried out in order to understand the bending strength of thin-rimmed spur gear. Works and experiment from the literature were studied, and their findings were extracted to understand the methods used. The most common method used to investigate bending strength is the numerical calculation. This method was used with several types of established equations and standards to predict gear failures. Next stage is to simulate the gear using Finite Element Method (FEM) in order to get the analysis of gear strength. The most important stage is to put the gears to physical experiment or testing facilities to determine and validate all data from the numerical calculation and FEM method.

In order to solve the time-varying bending bearing capacity of orthogonal curve-face gear, we proposed the calculation and test method of bending stress of gear tooth root. Using the spatial engagement theory and gear carrying capacity theory, the parametric equations of pitch curve and pressure angle on the pitch curve of orthogonal curve-face gear were derived, and the algorithm of equivalent tooth form factor and equivalent stress correction factor was obtained. Force condition in the meshing process of orthogonal curve-face gear was analyzed. The variation of principal curvature and force of orthogonal curve-face gear was achieved. Using the simplification algorithm of regarding the orthogonal curve-face gear pair as equivalent non-circular gear rack, the calculation method of bending stress of orthogonal curve-face gear was acquired, and the impact of basic structure parameter of gear pair on bending stress was analyzed. Using five-axis CNC machining to process the entity. Experimental of orthogonal curve-face gear using strain gauges was carried out to justify the correction of the theory. Comparing the theoretical calculation and experimental results, the variation laws was similar, and then the calculation method of bending strength of orthogonal curve-face gear was verified.
