为了预测螺旋伞齿轮传动变速箱的搅拌功率损失，基于计算流体动力学(CFD)方法，建立了包括齿轮箱壳体、螺旋伞齿轮副和导油装置在内的直升机中间变速箱飞溅润滑的数值仿真模型，并通过实验对搅拌功率损失的预测进行了验证。利用该模型计算了螺旋伞齿轮传动变速箱的搅拌功率损失，分析了齿轮转速、充油量、油温、油动粘度、机油密度、直升机倾角等参数对搅拌功率损失的影响。
To predict the churning power losses in a gearbox with spiral bevel geared transmission, based on the Computational Fluid Dynamics (CFD) method, a numerical simulation model for the splash lubrication of the intermediate gearbox of a helicopter including gear box housing, a spiral bevel gear pair and an oil guide device is established and validated by the churning power losses prediction of experiments showing a good agreement. With the model, churning power losses of a gearbox with spiral bevel geared transmission are obtained; influences of gear rotational speed, oil fill level, oil temperature, oil dynamic viscosity, oil density, and tilt angle of the helicopter, on the churning power losses are analyzed.
