“…Even if a meshing gear in the time domain has an accurate involute tooth profile under working conditions, the gear teeth will change the base joints of the driving and driven gears to the position of the meshing line. This is attributed to the deformation of the gear tooth load and the installation error under the initial action of the meshing force which is no longer equal, and therefore, it causes gear tooth surface interference that deviates the meshing point from the normal meshing line [4][5][6].…”

In a pair of actual gears alternating meshing process, the transmission system errors and thermal elastic deformation of the gear teeth can cause gears in the meshing zone to form high contact pairs inconsistently mesh-in and mesh-out points to deviate from the theoretical line, which will lead to sudden changes in meshing velocity and an instantaneous meshing effect. Offline meshing impact generates large additional loads, and it increases the vibration and noise of gear transmission system. Further, the gear teeth mesh-in impact is significantly greater than that of gear teeth mesh out. Therefore, to analyze the impact with the minimum value of gear teeth mesh in, the initial mesh-in points need to be determined, and the meshing impact velocity and impact force of teeth meshing-out need to be calculated. The optimized meshing tooth-pair contact interface (CI) anti-impact numerical calculation mode is validated using the loaded teeth contact analysis method.

“…Even if the time-domain meshing gear has a fully accurate involute tooth profile under the working condition, the gear teeth will change the base joints of driving and driven gears in the position of the meshing line due to the deformation of the gear tooth load and the installation error under the initial action of meshing force, which will no longer be equal, resulting in the gear tooth surface interference which will cause the meshing point to deviate from the normal meshing line [2][3][4]. Some scholars had suggested three kinds of meshing impact (such as meshing-in impact, mesh-out impact and node impact) could appear in gear transmission system [5]. The influence of node impact was minimal and the effect of mesh-out impact was less than that of meshing-in impact.…”

In gear pair actual alternating meshing process, the comprehensive errors of the transmission system and the thermal elastic deformation of the teeth body cause the gears in the meshing state to high pair contact nodes inconsistently, especially the transient process of meshing-in and meshing-out points will deviate from the theoretical line, which will cause a sudden change in the meshing velocity and cause instantaneous impact of meshing. Off line meshing impact will generate large additional loads, which has attracted many attentions. The gear transmission system vibration and noise are increased, and the impact of gear teeth meshing-in is significantly greater than that of meshing-out. Therefore, optimal analysis of the impact with the minimum value of gear teeth meshing-in includes determining the initial meshing points, calculating of meshing impact velocity and the impact force of teeth meshing-out. The optimized calculation model using loaded teeth contact analysis method is validated.

“…14 TSM technology has been the most effective way to improve the gear teeth meshing performance and reduce vibration and noise of the gear transmission system (GTS), the TSM effect mechanism and modification parameter selection principles have become a consensus. [15][16][17] Moreover, most of these research results are based on the assumption of the static state of GTS, and there are few studies on TEL considering the transient dynamic conditions of GTS meshing. There are two common problems in their research.…”

The pre-research project aims to propose a method of optimizing tooth surface modification (TSM) fitting under thermoelastic lubrication (TEL) conditions to reveal the most popular and concerned mechanism issues in the field of mechanical engineering. This is an exploratory study, mainly considering the gear comprehensive error and TSM state of TEL contact interfaces are extremely harsh, which complicates simulation analysis and optimal design. TSM simulation has fitted numerically agreement with optimized results obtained experimentally, which means that they can, whether isolated or by using a multiscale coupling method, start to be adopted to revise, and verify meta-models for thermoelastic characteristics (TECs) under TEL problems. This subject involves the TSM fitting of the theoretical teeth surface superimposed structure, and performs 3D and diagonal modification optimization design, obtains the modified surface position and normal vectors, according to load teeth contact analysis (LTCA), a variety of optimized modification models are established and complex curved surfaces are analyzed to fit the actual gear teeth surface thermoelastic contact numerical simulation, which has been further demonstrated and expressed in the type experiment combined with actual key working conditions and multiple influencing parameters, which is of great significance to the development of modern gear transmission system.
