一、前言液体静压技术的原理是用泵将润滑液送入支承和被支承元件的间隙中,形成一层压力液膜,以支承载荷。这种支承即使在零速时也能保持液体润滑状态,因为液膜使两支承面完全分开。因此,这类支承的起动摩擦几乎等于零,温升低,抗振性好,刚度高,在各类机床以及其他机械方面有广泛的应用。关于静压技术在高精度、高效率、数控及大型等类机床方面的应用情况已综合报导过,在此不再赘述。下面仅就近几年来,静压技术的研究和应用方面的某些动向作一简单的介绍。
I. Introduction The principle of hydrostatic pressure technology is to pump the lubricating fluid into the gap between the support and the supported element to form a layer of pressure liquid film to support the load. This support retains liquid lubrication even at zero speed because the liquid film completely separates the two surfaces. Therefore, the starting friction of such bearings is almost equal to zero, low temperature rise, good vibration resistance, high rigidity, in all kinds of machine tools and other machinery has a wide range of applications. The application of static pressure technology in high-precision, high-efficiency, numerical control and large-scale machine tools has been reported comprehensively, and will not be repeated here. The following only in recent years, static pressure technology research and application of some of the trends for a brief introduction.
