我厂的外圆磨床有不少是苏联制造的老产品,磨头轴承结构比较陈旧,大部分都是内圆外锥式单油楔动压滑动轴承。这类轴承确定间隙比较困难,如使用不当,低速不能形成动压,高速时常产生高热,严重时甚至自动闷车(抱轴)。修理这类轴类。对刮研、装配和调整要求技术高。为了提高修理质量和经济效益,我们用小孔节流液体静压轴承改造这类旧磨床,提高了磨床的精度及光洁度,效果较好。
Many of the cylindrical grinders in our factory are old products manufactured by the Soviet Union. The structure of the grinding head bearing is rather old, most of them are the single-wedge hydrodynamic sliding bearings with inner cone and single cone. Such bearings to determine the gap more difficult, such as improper use, low-speed dynamic pressure can not form, high-speed high-heat often, serious or even auto-boring car (axle). Repair these shafts. Scratching, assembly and adjustment require high technology. In order to improve the quality of repair and economic benefits, we use small hole hydrostatic hydrostatic bearings to transform such old grinder, improve the accuracy and finish grinding machine, the effect is better.
