液体静压轴承作为一项新技术,它具有摩擦系数小、寿命长、精度保持性好,回转精度高,抗振性好及转速的改变对刚度的影响较小等优点。随着社会主义建设事业的迅速发展,特别是无产阶级文化大革命以来,我国已在许多地区和单位将静压技术应用到设备的改造和产品中,取得了一定的成果,并逐渐推广应用到各工业行业的机械设备中去。在195柴油机连杆生产线上,精镗连杆孔的设备是一台自制的卧式双头金刚镗床,镗头的回转精度依靠精密滚动轴承36211来保证,但这种轴承的寿命短,其精度的损失
Hydrostatic bearing as a new technology, it has a small friction coefficient, long life, good accuracy and maintainability, high rotation accuracy, good vibration resistance and speed changes have little effect on the stiffness and so on. With the rapid development of the socialist construction, especially since the Great Proletarian Cultural Revolution, China has applied static pressure technology to equipment reform and products in many regions and units and has achieved certain achievements and gradually popularized and applied it to various fields Industrial machinery and equipment to go. In the 195 diesel engine connecting rod production line, the equipment of the fine boring rod hole is a self-made horizontal double head boring machine. The precision of the boring head depends on the precision roller bearing 36211. However, loss
