Abstract

With the increasing speed of aviation spiral bevel gears, the load-independent windage power losses caused by hydrodynamic have increasingly more influence on gear transmission efficiency. Firstly, a test rig for the windage power loss of spiral bevel gear under oil-jet lubrication is established, and on this basis, a method for measuring windage torque is proposed. Next, the interactive effects of different injection lubrication parameters on the windage power loss were studied by orthogonal experiment, and the formula for calculating the windage loss was obtained by fitting the experimental data. Then, the fluid distribution, velocity field and pressure field around the gear were analysed by using a computational fluid dynamics (CFD) numerical model, and the mechanical and energy characteristics of the gear windage power loss were obtained. Finally, the dimensionless processing of the windage moment was carried out, and the variation of the dimensionless windage moment coefficient with the rotational Reynolds number is obtained. The comparison between the dimensionless windage moment coefficient of experimental data and simulation results shows that the CFD values are in good agreement with the measured data. This study provides experimental and methodological guidance for the calculation of windage power loss and windage reduction design of aviation gear pair under oil injection lubrication.

喷油润滑航空螺旋锥齿轮气动功率损失特性的实验研究与数值分析

随着航空弧齿锥齿轮转速的提高，流体动力学引起的与载荷无关的风阻功率损失对齿轮传动效率的影响越来越大。首先，建立了螺旋锥齿轮在油喷射润滑下的风阻功率损失试验台，并在此基础上提出了一种测量风阻转矩的方法。其次，通过正交实验研究了不同注入润滑参数对风电功率损失的交互影响，并对实验数据进行拟合，得出了风电功率损耗的计算公式。然后，利用计算流体动力学（CFD）数值模型分析了齿轮周围的流体分布、速度场和压力场，得到了齿轮风阻功率损失的力学和能量特性。最后，对风阻矩进行了无量纲处理，得到了无量纲风阻矩系数随旋转雷诺数的变化规律。实验数据的无量纲风阻矩系数与模拟结果的比较表明，CFD数值与实测数据吻合较好。该研究为航空齿轮副在喷油润滑下的风阻功率损失计算和减阻设计提供了实验和方法指导。
