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.
