本文探讨了一种新型滑动轴承——小孔式(毛细管式或孔口式)周向不均匀分布的动静压滑动轴承,它综合利用了静压轴承和动压轴承的优点,制造简单,比油腔式静压轴承和隙缝式动静压轴承的性能优越,是一种很有前途的轴承型式。随着机器向高速、大功率方向发展,功率损耗是个突出矛盾。本文编制了在满足等式和不等式约束条件下,以单位承载量下的功率损耗为目标函数进行优化设计的通用FORTRAN优化设计程序,以提供最佳设计数据。本文还对油膜的破裂和再形成,空穴区雷诺方程式的边界条件,进油小孔处的流量连续性方程式以及这种轴承的程序设计和通用优化设计程序进行了较详细的讨论。
In this paper, a new type of sliding bearing-orifice (capillary or orifice) circumferential uneven hydrodynamic sliding bearing is discussed, which makes full use of the advantages of hydrostatic bearing and hydrodynamic bearing. It is easy to manufacture, Oil-cavity hydrostatic pressure and slotted static and dynamic pressure bearing performance is superior, is a promising type of bearing. With the machine to high-speed, high-power direction, power loss is a prominent contradiction. In this paper, a generalized FORTRAN optimization design program, which is optimized under the constraints of equality and inequality, with the power loss per unit load as the objective function, is compiled to provide the best design data. This paper also discusses the rupture and reformation of the oil film, the boundary conditions of the Reynolds equation in the cavity area, the flow continuity equation at the inlet hole and the program design and general optimization design procedure of the bearing.
