一、为什么要研究静压轴承的动态性能静压轴承这项新技术,具有滑移面无金属接触,达到完全液体润滑,因而无磨损、起动磨擦力甚小、承载力大、适应运转速度范围广、支承精度高等一系列的优点。近年来随着我国机械工业的迅速发展,作为精密轴承的液体静压轴承获得日益广泛的应用。例如在机床制造行业中已有效地推广到大型车床、大型立车、大型镗铣床、各类高精度磨床、大型精密磨
First, why study the dynamic performance of hydrostatic bearings Hydrostatic bearing this new technology, with no metal contact slip surface, to achieve complete liquid lubrication, and therefore no wear and tear, starting friction is very small, bearing capacity, to adapt to the operating speed range Wide, high precision bearing a series of advantages. In recent years, with the rapid development of China’s machinery industry, hydrostatic bearings as precision bearings are gaining more and more widespread applications. For example, in the machine tool manufacturing industry has been effectively extended to large lathes, large vertical lathes, large boring and milling machine, all kinds of high-precision grinding machines, large-scale precision grinding
