如图所示的滚柱轴承,是英国INA轴承公司开发的低摩擦、重载滚柱轴承。其外圈上分布着一系列小孔。回转时,经小孔压入压力油,各滚柱在油压的作用下紧压在轴承的内圈上。因此,相互间无滑动运动。由于各处油压相同,滚柱间间隙相等,故无需传统轴承的保持架,轴承结构简单。该轴承由于不断输入油液,这对轴承起到了冷却作用,使轴承性能大为改善,使用寿命得以提高,能
As shown in the roller bearings, the British company INA Bearing developed low-friction, heavy roller bearings. The outer ring is distributed with a series of small holes. Rotation, through the small hole into the pressure oil, the roller pressure in the bearing under the action of the inner ring. Therefore, no sliding movement between each other. Because of the same pressure throughout the gap between the rollers equal, so there is no need for the traditional bearing cage, the bearing structure is simple. The bearing due to continuous input of oil, which played a cooling bearing, greatly improving the performance of the bearing, the service life can be improved, can
