摘    要
本次毕业设计的主要任务是滑动轴承综合试验台改进设计（含供油系统的设计）。由于高速主轴具有相当高的速度，因此就需要作为转子系统支撑件的轴承要具备高精度﹑低功耗﹑高稳定性等优点。而动静压轴承集静压轴承和动压轴承的优点于一体，正符合高速主轴的要求。
本次设计从润滑的角度首先分析了动压轴承和静压轴承，分析了其支撑原理以及各自特点。然后又分析了动静压轴承的静态特性。根据以往经验选取了滑动轴承的结构参数，采用超松弛迭代数值计算方法解雷诺方程线性方程组，得到二维压力分布。对其承载能力﹑流量﹑偏位角也进行了无量纲计算，然后根据计算结果进行了分析和讨论。最后进行了试验台设计，对整个供油路线和主要部件及其功能进行了分析设计，采用液压装置及滑动轴承的组合运用实现对试验台平稳高效的控制。

Sliding bearing to improve the design of a comprehensive test-bed

                            
Abstract
  The task of this graduating design is the analysis and calculation of the hybrid bearing in the fast electric shaft. Because of the rapid speed of the fast shaft, bearing with high precision, low power consuming and high stability is needed to act as the supporter of the machine rotor-support system. The hybrid bearing had the advantages of both hydrostatic bearing and hydrodynamic bearing, so it is just the one fit for the fast shaft.
   First, the hydrostatic bearing and hydrodynamic bearing are analysed based on lubrication theory and in this design, and I also analysed the support principle and their characteristic. Then the static characteristic of the hybrid bearing is also analyse. The frame parameter is selected by anciently experience. The computer-aided programming is worked out by means of the successive over-relaxation method for the solution of Reynolds liner equation group. And the two dimensionless computations of the loading capacity, the flow, the friction and stiffness are completed and explained. At last, the gasoline tank is designed. The whole route of the oil-supported and the function of the mostly components are analysed, using the hydraulic devices and a combination of sliding bearing on the test stand to achieve a smooth and efficient control.
