摘要

本文建立了斜齿轮的摩擦动力学模型。润滑子模型采用斜齿轮有限线热弹流动力学润滑模型。在动力学子模型中考虑了齿轮的横向振动、轴向振动和齿轮轴的扭转振动。结果表明，在动态摩擦模型下，斜齿轮的摩擦学参数与准静态模型有明显的偏差，特别是在齿副啮合区域。摩擦激励主要影响齿轮沿离动方向的振动。工作条件对斜齿轮副的摩擦学和动力学性能的影响是显著的，特别是在与齿轮的特征频率有关的情况下。

Tribological characteristics evaluation of a helical gear pair based on the tribo-dynamic model

In this paper, a tribo-dynamic model of a helical gear is established. For the lubrication sub-model, a finite line thermal elastohydrodynamic lubrication model of helical gear is adopted. The lateral vibration, axial vibration of gear and torsional vibration of the gear shaft are considered in the dynamic sub-model. Results show that the tribological parameters of helical gear under the tribo-dynamic model deviate significantly from that of the quasi-static model, especially in the engaging-in region of tooth pair. The friction excitation mainly affects the vibration along the off-line-of-action direction of the gears. The influence of operating conditions on the tribological and dynamic properties of a helical gear pair is significant, especially in the case related to the characteristic frequency of gears.

期刊介绍： Lubrication Science is devoted to high-quality research which notably advances fundamental and applied aspects of the science and technology related to lubrication. It publishes research articles, short communications and reviews which demonstrate novelty and cutting edge science in the field, aiming to become a key specialised venue for communicating advances in lubrication research and development. Lubrication is a diverse discipline ranging from lubrication concepts in industrial and automotive engineering, solid-state and gas lubrication, micro & nanolubrication phenomena, to lubrication in biological systems. To investigate these areas the scope of the journal encourages fundamental and application-based studies on: Synthesis, chemistry and the broader development of high-performing and environmentally adapted lubricants and additives. State of the art analytical tools and characterisation of lubricants, lubricated surfaces and interfaces. Solid lubricants, self-lubricating coatings and composites, lubricating nanoparticles. Gas lubrication. Extreme-conditions lubrication. Green-lubrication technology and lubricants. Tribochemistry and tribocorrosion of environment- and lubricant-interface interactions. Modelling of lubrication mechanisms and interface phenomena on different scales: from atomic and molecular to mezzo and structural. Modelling hydrodynamic and thin film lubrication. All lubrication related aspects of nanotribology. Surface-lubricant interface interactions and phenomena: wetting, adhesion and adsorption. Bio-lubrication, bio-lubricants and lubricated biological systems. Other novel and cutting-edge aspects of lubrication in all lubrication regimes.
