以螺旋槽气体动压轴承为研究对象,建立螺旋槽气体动压轴承润滑分析的数学模型;通过几何变换简化模型,采用有限差分法对Reynolds方程进行求解,计算轴承间隙内的三维压力分布,揭示轴承结构参数和运行参数变化对轴承稳态气膜压力分布、轴承承载能力的影响规律,结果表明,为使动压轴承得到良好的静态特性,必须合理选择轴承结构设计参数。 Taking the helical grooved hydrodynamic bearing as the research object, the mathematical model of helical grooved hydrodynamic bearing lubrication analysis was established. By geometric transformation, the model was simplified and the Reynolds equation was solved by the finite difference method to calculate the three-dimensional pressure distribution in the bearing clearance. Bearing structure parameters and operating parameters of the bearing steady-state film pressure distribution, bearing capacity of the law, the results show that, in order to get a good static pressure dynamic bearing properties, the bearing structural design parameters must be reasonable choice.
