轴承是机床上不可缺少的部件。当其他部件在轴上彼此相对运动时,用来保持轴的中心位置及控制该运动的部件,就称之为轴承。轴承是各类机床设备的重要基础零部件,它的精度、性能、寿命对机床的优良起着决定性的作用。在机械产品中,轴承属于高精度产品,不仅要懂得轴承的性能、分类,还要明白轴承的型号,轴承的制作需要材料科学、热处理技术、精密加工和测量技术、数控技术,因此轴承又是一个代表国家科技实力的产品。而在机床中,主轴的轴承室尤为重要的。
Bearing is an indispensable part of the machine. When other parts are moved relative to each other on the shaft, the parts used to hold the center of the shaft and to control the movement are called bearings. Bearing is an important foundation for all types of machine tools and components, its accuracy, performance, life expectancy on the machine plays a decisive role. In mechanical products, bearings are high-precision products, not only to understand the bearing performance, classification, but also understand the bearing type, bearing the production of materials science, heat treatment technology, precision machining and measurement technology, numerical control technology, so the bearing is A product that represents the strength of national science and technology. In the machine tool, the spindle bearing room is particularly important.
