Abstract

In order to clarify the effect of mixed lubrication methods on the oil flow and power loss of the gearbox, this study adopts a high-precision moving particle semi-implicit (MPS) method to investigate the lubrication of the gearbox under the joint influence of splash lubrication and oil injection lubrication. The accuracy of the numerical method to calculate the churning torque was verified by the constructed test rig. The effects of rotational speed, immersion depth, injection volume rate, and oil injection angle were analyzed and evaluated for lubrication. The results show that better lubrication can be achieved with relatively small churning torques by using a hybrid lubrication method. This provides some references for engineering applications of gearboxes.

齿轮箱混合润滑模式下的润滑性能和搅动损失研究

为了阐明混合润滑方式对齿轮箱油流和功率损失的影响，本研究采用高精度移动质点半隐式（MPS）方法研究了齿轮箱在飞溅润滑和喷油润滑共同影响下的润滑情况。所构建的试验台验证了数值方法计算搅动扭矩的准确性。分析和评估了转速、浸入深度、喷油量率和喷油角度对润滑的影响。结果表明，使用混合润滑方法可以在相对较小的搅动扭矩下获得更好的润滑效果。这为齿轮箱的工程应用提供了一些参考。
