The invention provides a ship stern shaft closed type water lubrication system suitable for an inland river sediment water area. The ship stern shaft closed type water lubrication system comprises a bearing seat, a water lubrication stern bearing, a stern shaft, a leather cup sealing ring, a sediment filtering net and a flushing device. The water-lubricated stern bearing is inserted into the bearing seat; the stern shaft is inserted into the water-lubricated stern bearing; three layers of leather cup sealing rings are arranged in a gap between the leather cup sealing rings and the bearing seat in the axial direction of the stern shaft, the directions of the front two layers of leather cup sealing rings close to the outside face outwards, a sediment treatment bin is formed between the front two layers of leather cup sealing rings close to the outside, and the direction of the third layer of leather cup sealing ring faces inwards. The closed water lubrication area of the stern shaft is divided into the sediment treatment cabin and the water lubrication cabin through the three layers of leather cup sealing rings, the directions of the front two layers of leather cup sealing rings close to the outside face outwards, and under the pressure effect of external water, the leather cup sealing rings are automatically attached to the stern shaft for sealing; and sediment accumulation is prevented through a flushing device, water flow is controllably injected into the water lubrication cabin, and the lubrication state is improved.
本发明的技术方案提供一种适用于内河泥沙水域的船舶艉轴闭式水润滑系统,包括轴承座、水润滑艉轴承、艉轴、皮碗密封圈、泥沙过滤网和冲水装置;所述水润滑艉轴承插装在所述轴承座内;所述艉轴插装在所述水润滑艉轴承内;所述皮碗密封圈沿着所述艉轴的轴向在与所述轴承座的间隙内设置为三层,且靠外的前两层所述皮碗密封圈的方向朝外,并在之间形成泥沙处理舱,第三层所述皮碗密封圈方向朝内。本发明通过三层皮碗密封圈的设置将艉轴闭式水润滑区域分为了泥沙处理舱和水润滑舱,并且靠外的前两层皮碗密封圈的方向朝外,在外部水的压力作用下,自动的贴紧艉轴进行密封;以冲水装置,防止泥沙堆积,并对水润滑舱可控的注入水流,改善润滑状态。
