Double-oil-surface floating bearing

The utility model discloses a double-oil-surface floating bearing which comprises a floating bearing body, and the floating bearing body is provided with a first oleophobic hole, an inner oil groove,an outer oil groove, oil groove heat dissipation slim holes, a second oleophobic hole and heat dissipation micro grooves. The oil film on the inner side and the oil film on the outer side are mutuallydredged by utilizing the relative movement generated between the oil films and the dynamic bearing body 1 and utilizing the principle of an inclined plane to form a circulating flow path of the oil films. Therefore, the utility model has the following beneficial effects: (1) the heat dissipation efficiency is improved; (2) the problem of non-uniform oil film is solved; and (3) the working resistance of the bearing is reduced. 本实用新型公开了一种双油面浮动轴承，包括浮动轴承本体，浮动轴承本体设有第一疏油孔、内油槽、外油槽、油槽散热细孔、第二疏油孔和散热微槽。利用油膜与动轴承本体1之间产生的相对运动，以及利用斜面的原理将内侧油膜和外侧油膜互相疏导，形成油膜的循环流路。因此，本实用新型具有如下有益效果：（1）提高散热效率；（2）解决油膜不均匀的问题；（3）减小轴承工作阻力。
