日本精工株式会社(NSK)研制成功的高精度盒式空气静压轴承,具有精度高、体积小、重量轻、刚性好、结构简单等特点。它的诞生使精密机械的性能和精度向更高阶段发展。 1.种类和原理空气静压轴承是一种把外界压缩空气引入轴承间隙中(间隙为几个μm),用非接触方法来支承轴承,如图1所示。该轴承一般有如下几种:图2a为多阻尼孔式,又可分为自成阻尼式(图2a-2)和镶小孔阻尼式(图2a-
Japan’s Seiko Co., Ltd. (NSK) successfully developed high-precision cartridge air hydrostatic bearings, with high precision, small size, light weight, good rigidity, simple structure and so on. It was born to the precision machinery performance and precision to a higher stage of development. 1. Types and Principles Air hydrostatic bearings are a way to introduce outside compressed air into the bearing clearance (clearance of a few μm), using non-contact method to support the bearing, shown in Figure 1. The bearings are generally the following: Figure 2a is a multi-damping hole, can be divided into self-damping (Figure 2a-2) and small hole damping (Figure 2a-
