Abstract

For spiral bevel and hypoid gears under high-speed and heavy-duty conditions, time-varying meshing interface experiences high temperature rises due to thermal elastohydrodynamic lubrication (TEHL) effect. While considering the rough tooth surface asperities, it is easy to break the oil film, and this becomes mixed state easily induces various failures such as pitting, scuffing, and wear. Currently, the mixed TEHL mechanism is a very tough task for spiral bevel and hypoid gears, owing to temperature effect lacking systematic in-depth analysis. In full consideration of time-varying geometric and kinematic characteristics, an innovative mixed TEHL modeling is proposed. This model comprehensively considers many factors such as lubricant temperature rise, solid heat conduction, arbitrary directionality of interface speed, rheological properties of the lubricant, actual surface roughness, and elastic deformation of the tooth surface. In this paper, a semi-system approach is utilized to discretize and solve the Reynolds equation for excellent iterative convergence and high computational efficiency. This approach enables numerical simulation across the entire spectrum, from full-film lubrication to mixed lubrication, and ultimately to boundary lubrication. Comparing with the empirical data, a set of hypoid gears in automobile main reducer transmission system is exercised to validate high precision of this modeling.

一种创新的螺旋锥齿轮和准双曲面齿轮混合热弹流润滑建模方法

对于高速重载工况下的螺旋锥齿轮和准双曲面齿轮，由于热弹流润滑（TEHL）效应，时变啮合界面会出现高温升。同时考虑到粗糙的齿面凹凸不平，容易使油膜破裂，从而变为混合状态，容易诱发点蚀、划伤、磨损等各种失效。目前，螺旋锥齿轮和准双曲面齿轮的温度效应是一项非常艰巨的任务，缺乏系统的深入分析。在充分考虑时变几何和运动特性的基础上，提出了一种新颖的混合TEHL建模方法。该模型综合考虑了润滑剂温升、固体热传导、界面速度的任意方向性、润滑剂的流变性、实际表面粗糙度和齿面弹性变形等因素。本文采用半系统方法对雷诺方程进行离散求解，具有较好的迭代收敛性和较高的计算效率。这种方法可以在整个范围内进行数值模拟，从全膜润滑到混合润滑，最终到边界润滑。以汽车主减速器传动系统的准双曲面齿轮为例，与经验数据进行对比，验证了该模型的精度。

期刊介绍： International Communications in Heat and Mass Transfer serves as a world forum for the rapid dissemination of new ideas, new measurement techniques, preliminary findings of ongoing investigations, discussions, and criticisms in the field of heat and mass transfer. Two types of manuscript will be considered for publication: communications (short reports of new work or discussions of work which has already been published) and summaries (abstracts of reports, theses or manuscripts which are too long for publication in full). Together with its companion publication, International Journal of Heat and Mass Transfer, with which it shares the same Board of Editors, this journal is read by research workers and engineers throughout the world.
