Abstract
The study employed a two-dimensional (2D) space with multibody dynamics as the physics to simulate the dynamic behaviour of intermeshing gears. Both the gear teeth and the gear body were employed to simulate the principal stress and strain as well as the Von Mises stress of the gear system. A pair of meshing teeth were examined from the pinion and the other from the gear for accurate contact stress-strain simulation. The validity of the proposed gear simulation was verified from principal surface stress, Von Mises stress, principal surface strain, elastic strain and total displacement. The results show that the dynamic behaviour of the gear could be attributed to the critical meshing characteristics of the single and double teeth. The peak-to-peak pattern of the Von Mises stress indicates the essential points of stress, which could cause the occurrence of the failure modes. The research of the gear motion study is profoundly enriched and served as a critical reference for gear design.
Highlights
Spur gears have played an enormous role of power transmission in the field of equipment/machinery, and their dynamic behaviour owing to variation in the tooth geometry has a significant impact on the transmission performance and the overall reliability of the equipment [1]
It can be depicted from the result that the gear tooth experienced a multiaxial state of stress since the behaviour of the gear geometry reflects that of the principal stress state
Seven (7) principal stress and three (3) principal strain, including one (1) volumetric strain were established during the simulation
Summary
Spur gears have played an enormous role of power transmission in the field of equipment/machinery, and their dynamic behaviour owing to variation in the tooth geometry has a significant impact on the transmission performance and the overall reliability of the equipment [1]. One reason why an integrated approach must be adopted for modelling and predicting the likely occurrence of bending stress at the root of the tooth [2] This failure occurring at the root region of the tooth was attributed to load distribution, improper operating conditions as well as flaws during the manufacturing of the gear. According to Pleguezuelos et al [6], a quasi-static transmission error occurs in a pair of gears in mesh, which is attributed to load distribution at the teeth. This could result in excessive deflection of the gears and subsequent failure due to fatigue [7].
