Abstract

In order to predict the spiral bevel gear churning power loss, based on the Computational Fluid Dynamics (CFD) method, the computational model for the splash lubrication of the spiral bevel gear pair is established and validated by experiments. The churning power loss of spiral bevel gears is obtained and the corresponding flow field distribution in the gearbox with a pair of spiral bevel gears is analysed under a standard operating condition. For the churning power loss of spiral bevel gears, the loss of teeth surface is mainly caused by pressure while the loss of gear side is mainly generated by the viscous force. The effects of the gear rotational speed, oil level, oil temperature and oil shroud on the churning loss are also investigated and analysed. Ultimately, an optimisation method is proposed for the original spiral bevel geared transmission.

飞溅润滑系统中螺旋锥齿轮搅动功率损失的数值研究

为了预测螺旋锥齿轮的搅动功率损失，基于计算流体动力学（CFD）方法，建立了螺旋锥齿轮对飞溅润滑的计算模型，并通过实验进行了验证。获得了螺旋锥齿轮的搅动功率损失，并分析了标准工作条件下带有一对螺旋锥齿轮的齿轮箱中相应的流场分布。对于螺旋锥齿轮的搅动功率损失，齿面损失主要由压力引起，而齿侧损失主要由粘性力产生。此外，还研究和分析了齿轮转速、油位、油温和油护罩对搅油损失的影响。最后，针对原始螺旋锥齿轮传动提出了一种优化方法。

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.
