“…Lubrication significantly affect contact fatigue life of tooth surfaces during helical gear operation. Inadequate lubrication during service will cause pitting and glueing faults [31]. The oil between the engaging teeth acts as a spring-damping element, which can govern the frictional state and engagement characteristics [20].…”

For the helical gear fault diagnosis investigation, it is essential to establish a pitting dynamics model that incorporates several nonlinear parameters to simulate the fault characteristics. This paper proposes a multi-degree-of-freedom analytical nonlinear dynamic model of helical gear pair under pitting fault, introducing the stiffness and damping parameters of gear matrix and lubricant film, the variable friction coefficient of elastohydrodynamic lubrication (EHL), and the measured meshing profile error. Contact fatigue experiments are carried out with a helical gear transmission test bench to gain the full-stage vibration response from healthy to severe pitting fault conditions to validate the reliability of the proposed nonlinear dynamics model. The distribution and amplitude of the eigenfrequencies of the analytical results, considering the influence of the lubricating oil film, are more consistent with the experimental measurements, where the sidebands between the three times and four times fundamental frequency are in acceptable agreement. The comparison results confirm the importance of considering the influence of the lubricant film when studying the dynamics of gear tooth pitting failures, and the analytical method and proposed model can be a reference for dynamical simulation modelling for gear fatigue failure diagnosis and analysis.

The performance of tooth-sum altered (ATS) gears is determined by the factors influenced by their profile geometry. This study aims to explore the influence of gear geometry modification on tribological aspects that affect surface wear in ATS spur gears. A computer code is developed to simulate surface wear numerically, using Archard's wear model, Greenwood-Williamson micro-asperity contact model, and Johnson’s load-sharing approach. The outcomes of the study indicate that the low contact ratio ATS gears promote the formation of thick oil film owing to reduced specific sliding and increased speed. However, high contact ratio ATS gears create unfavorable operating conditions resulting in extreme boundary lubrication. The effectiveness of lubricant oil film in reducing wear in ATS gears is associated with its modified profile, sliding velocities, load bearing, operating temperature, and oil viscosity.

“…Chen et al [17] established a wear evolution model of gear tooth profile changes caused by cumulative wear. Zhang et al [18] studied the wear and contact fatigue of involute modified gears under minimum-quantity lubrication by updating the contact path and gear profile in real time. Simultaneously, Feng and Zhang et al [19,20], respectively, predicted the wear resulting from tooth profile changes to mitigate failures and minimize economic losses.…”

In order to improve the contact strength and reduce the sliding friction of the gear pair, an internal cylindrical gear pair with a curved meshing line is studied in this paper. Firstly, a curved meshing line is designed. The tooth profiles of the internal gear pair with the designed meshing line are calculated by using differential geometry and the gear meshing principle. Secondly, a wear model is established by combining the finite element method and the Archard wear formula. Then, a numerical simulation is conducted; the relative curvature, sliding coefficient, sliding distance, maximum contact pressure, transmission error, and wear depth are calculated. Ultimately, the variation law of tooth surface wear of new gear with and without installation errors is observed under different stress cycles. On this basis, the influence of tooth modification on tooth surface wear is further researched. Through the results, the advantages of the introduced novel internal cylindrical gears in wear resistance are further demonstrated. The study in this paper provides new research ideas and methods for gear wear research and gear design.
