“…Three teeth FEM model of the gears has been used by several researchers [16][17][18]. The loads and boundary conditions are applied to both gears through their respective local centres, where the local centres are coupled to the rest of each gear body (pinion and wheel) using a kinematic link inside of the gear-to-shaft hole.…”

Misalignment between gear teeth is well-known to affect the strength properties of the gears. Despite many models proposed in research domain, investigations of the strength properties of a gear in axial misalignments condition are limited or yet to be discovered. In this study, an axial misalignment effects upon the strength properties of tooth surface contact stress and tooth root bending stress were discussed. A three tooth gear model was constructed based on a physical problem of two involute spur gears using an Autodesk Inventor gear design generator. The model was exported and analysed according to quasi-statics approach using a finiteelement method. Initially, the model was verified by comparing to the previous studies. The same models were then attached to a set of drive constraint misalignment plane, where a parametric study of the axial misalignments 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm and 0.5 mm was investigated. In general, results showed that axial misalignments do impact upon strength the strength properties of the gears. Tooth surface contact stress and tooth root bending stress showed between 5% to 15% incremental trend at different critical location while the strength reducing simultaneously with the application of axial misalignments. The pinion showed a weakening trend compare to the wheel when the application of axial misalignments took place. A series of verification tests was suggested to validate the finite-element model thus concluded that this research had achieved its main objectives where the strength properties of tooth surface contact stress and tooth root bending stress of the gear in axial misalignments gear were successfully investigated.

“…15 where the meshing stiffness obtained by (32) is shown. The non linear nature of the local contact model (13) becomes evident in the shift of the stiffness curve when the torque is increased. Moreover, in this figure, the increment of the period of double contact is clearly shown when the torque is higher.…”

“…This approach should have a fine mesh in the contact area and requires a great computational effort as it also includes nonlinear gap elements. On the other hand, the analysis of successive gear meshing positions requires the development of a new mesh for each contact position with the corresponding computational cost [12,13]. Unfortunately, the centres of the gears can move from their theoretical position leading to modifications in the mounting distance and thus also in the pressure angle and contact ratio.…”

The gear is one of the most widely used and vital parts having freeform surfaces. Accurate modelling and strength calculation are the basis of gear design and optimization. The traditional gear design and the existing finite element analysis methods cannot effectively solve these problems. Only a simple model can be established and the static strength analysis can be carried out at a certain meshing position. In this study, accurate equations of the tooth surfaces of a spur gear were derived based on the principle of gear shaping. Then, the parametric finite element modelling and simulation of the transient meshing of the spur gear have been realized using ANSYS software, and the stress distribution and variation trends of the gear during the meshing process have been analysed. Finally, the method is verified by simulation and comparison. The analysis results show that the effect of the tooth fillet surface on the strength of the gear is very large, and the bending stress and contact stress of the gear are nonlinear in the meshing process. The proposed method can accurately establish the model including the tooth fillet surface of the spur gear, and accurately analyse the strength of the spur gear pair. This makes up for the shortcomings of the existing method, and can be applied to other gear forms after appropriate modification.
