整体成型面动压轴承的一般型式如图1所示(图1,a—单面结构,4个成型面;b—双面结构,4个成型面)。精密机床(例如我国出产的 MEG 1432,MG 1420万能外园磨床,CQM 6132精密车床等)采用整体成型面动压轴承已取得了良好的效果。但是,目前这种轴承的设计计算资料却很欠缺。众所周知,对于精密机床上广泛采用的多瓦式调位动压轴承,现在已有一个关于其油膜承载能力的普遍(适用于任意琵数)而简便的计算方法([2]、[3]、[4]等)。但是对于整体成型面动压轴承,像这样的一个普遍(适用于单、双面结结构,任意成型面数)而简便的计算方法还不见有述及([2]等)。为了这个缘故,[4]曾尝试在[5]的基础上进行其承载能力的计算。但是由于计算过程的复杂程
The overall forming surface of the general type of hydrodynamic bearings shown in Figure 1 (Figure 1, a-single-sided structure, four molding surface; b-double-sided structure, four molding surface). Precision machine tools (such as MEG 1432 produced in China, MG 1420 universal external grinder, CQM 6132 precision lathe, etc.) with the overall profiled hydrodynamic bearings have achieved good results. However, the current design of the bearing calculation data is lacking. It is a well-known fact that for the multi-watt setting dynamic pressure bearings widely used on precision machine tools, there is now a simple and convenient calculation method for the bearing capacity of oil film (for any number of poles) [2], [3] [4] etc.). However, for the whole profiled hydrodynamic bearing, a simple calculation method such as this one (applicable to single and double knot structures, arbitrary number of forming faces) has not yet been mentioned ([2], etc.). For this reason, [4] attempted to calculate its carrying capacity on the basis of [5]. However, due to the complexity of the calculation process
