摘要： A shaft secured to a hub is inserted and rotatably supported in a sleeve secured to a base. A dynamic pressure groove is formed in the inner peripheral surface of the sleeve, and lubricant is sealed between the shaft and the sleeve. The rotation of the shaft causes dynamic pressure to generate in the lubricant due to the dynamic pressure groove, supporting the shaft floatingly. The crystallized-glass sleeve allows heat generated in a coil to be hardly transferred to the shaft, thereby reducing the variations in the clearance between the shaft and the sleeve due to temperature changes to a minimum in cooperation with the crystallized-glass sleeve with a low thermal expansion coefficient. Finishing accuracy of the bearing surface can be improved by chemical polishing. Consequently, the rotation accuracy can be improved and the leakage of lubricant due to the variations in the clearance can be prevented.
摘要翻译：固定到轮毂的轴被插入并可旋转地支撑在固定到基座上的套筒中。在套筒的内周面形成有动压槽，润滑剂被密封在轴与套筒之间。轴的旋转导致由于动压槽而在润滑剂中产生动态压力，浮动地支撑轴。结晶玻璃套筒允许在线圈中产生的热几乎不能传递到轴上，从而由于与具有低的结晶玻璃套管的温度变化而降低了轴和套筒之间的间隙的变化热膨胀系数。通过化学抛光可以提高轴承表面的精加工精度。因此，可以提高旋转精度，并且可以防止由于间隙的变化引起的润滑剂泄漏。
