摘　　要：为研究齿轮搅油损失机理问题,以及进一步提高齿轮传动效率,对齿轮搅油损失影响因素进行了研究。针对浸油润滑状态下的齿轮传动工况,建立了齿轮箱内流域有限元模型。应用该模型分析了不同转速和转向下齿轮外圆面、啮合区油液的飞溅变化,以及啮合点处的压力变化规律,并计算出齿轮阻力矩及搅油功耗损失值。研究结果表明,在中低速传动工况下,相对于齿轮转速的变化,转向的变化对啮合区域泵油量、外圆面甩油量、啮合点压力以及齿轮搅油损失的影响更大。该结论为后期齿轮传动节能研究提供了一定的理论依据。In order to make clear the mechanism of oil churning loss of gearbox and to further improve the efficiency of gear transmission,the factors that effects on oil churning losses are studied. The finite element model of oil fluid in gearbox is established in terms of the condition of the gear transmission under oil-immersed lubrication. The variation of oil splash and pressure on meshing point are analyzed under different speeds and directions of gear rotation,the gear resistance moment and the oil churning loss are calculated. The final results show that,under medium and low speed transmission condition,the change of gear rotating direction has greater influence on oil-pumping volume on the meshing area,oil-throwing volume of the outer circle of the gear,pressure on meshing points,and oil churning loss. The above conclusion may provide theoretical basis for later research on energy saving strategy of gear transmission.
