The plane friction watertight upper rudder bearing comprises a rudder bearing frame, a friction plate and a rudder bearing body, a plurality of limiting blocks arranged in the radial direction are arranged on the rudder bearing body, the friction plate comprises a plurality of fan-shaped friction modules, the friction modules are embedded between every two adjacent limiting blocks, and annular locking claws attached to the outer sides of the friction modules are arranged on the upper surface of the rudder bearing body. A plurality of first caulking grooves are formed in the upper surface of the rudder bearing body, a plurality of second caulking grooves are formed in the lower surface of the friction module, height adjusting blocks are arranged between the first caulking grooves and the second caulking grooves, and a rudder bearing frame is arranged on the friction plate. According to the plane friction watertight upper rudder bearing, the limiting blocks and the height adjusting blocks are matched with each other to fix the friction plates, and compared with the situation that the friction plates are fixed through bolts, the shear stress resistance can be increased by multiple times; and when the friction modules are locally replaced, the newly replaced friction modules are matched with the height adjusting blocks with the lower heights for use, so that the upper surfaces of the whole friction plates are flush, and the situation that all the friction modules are replaced is avoided.

    本发明提供一种平面摩擦水密上舵承,包括舵承架、摩擦片和舵承本体,舵承本体上有多个沿径向设置的限位块,摩擦片包括多块扇形摩擦模块,摩擦模块嵌设于相邻两限位块之间,舵承本体上表面设有贴设于摩擦模块外侧的环形锁爪,舵承本体上表面设有多个第一嵌槽,摩擦模块下表面设有多个第二嵌槽,第一嵌槽和第二嵌槽之间设有高度调节块,摩擦片上面设有舵承架。本发明提供的一种平面摩擦水密上舵承,采用限位块与高度调节块相互配合对摩擦片进行固定,与用螺栓固定的情况相比,抗剪应力能力可以增加数倍;且在局部更换摩擦模块时,将新更换的摩擦模块搭配高度较低的高度调节块进行使用,使摩擦片整体的上表面平齐,避免更换全部的摩擦模块。
