The invention discloses a water-lubricated tail bearing with a function division structure. The bearing comprises a rubber liner, a high-modulus middle lining and an outermost alloy bushing, wherein non-slotted areas are formed at the top and bottom of the rubber liner, a notch in the axial direction is arranged at the center of the non-slotted area at the bottom of the rubber liner, the areas other than the non-slotted areas of the rubber liner are slotted areas, and evenly distributed water grooves are formed in the inner surfaces of the slotted areas; and the high-modulus middle lining is sandwiched between the rubber liner and an alloy bushing, an axial bulge matched with the notch of the rubber liner is arranged at the bottom of the high-modulus middle lining, the top of the axial bulge is flush with the rubber liner, and a trapezoidal cross-section water tank is arranged in the middle of the axial bulge. The bearing has simple structure and makes full use of the advantages of various materials and structures, bearing capacity and lubrication performance can be improved, the requirements of bearing cooling and sediment discharge are met, and comprehensive performance of the bearing is the best.

    本发明公开了一种具有功能分区结构的水润滑尾轴承,包括橡胶内衬、高模量中间衬层和最外部的合金衬套,橡胶内衬的顶部和底部为未开槽区域,并且在橡胶内衬底部的未开槽区域中心处设有沿其轴向的缺口,橡胶内衬除去未开槽区域以外都是开槽区域,所述橡胶内衬的开槽区域的内表面设有均布的水槽;所述高模量中间衬层夹在橡胶内衬和合金衬套之间,所述高模量中间衬层底部设有与橡胶内衬的缺口配合的轴向凸起,轴向凸起顶部与橡胶内衬平齐,所述轴向凸起中部设有一个梯形截面水槽。该轴承结构简单,充分利用了多种材料和结构的优点,能够提高轴承的承载能力、润滑性能,满足轴承冷却及泥沙排泄需求,使轴承的综合性能最佳。
