摘要： The present disclosure relates to sealing the propeller shaft of a ship using a sealing having a group of lip seals arranged consecutively in a direction of the propeller shaft so that a seal chamber is created between adjacent lip seals. The pressure of the first seal chamber on the propeller side can be close to the pressure of the surrounding water at the propeller shaft level, and the pressure of the second seal chamber furthest from the propeller can be adjusted to a fixed value that is lower than the pressure of the first seal chamber. The pressure of a third chamber located between the first chamber and the second chamber can be adjustable by pressure regulation devices to a value between the pressure values of the first and the second chambers by adjusting the pressure loss caused by the flow of a liquid medium.
摘要翻译：本公开涉及使用具有沿传动轴的方向连续布置的一组唇形密封件的密封来密封船舶的传动轴，从而在相邻的唇形密封件之间形成密封室。螺旋桨一侧的第一密封室的压力可以接近驱动轴水平面处的周围水的压力，并且距离螺旋桨最远的第二密封室的压力可以被调节到低于第一密封室的压力。位于第一室和第二室之间的第三室的压力可以通过调节由液体介质的流动引起的压力损失，通过压力调节装置调节到第一和第二室的压力值之间的值。

摘要： The target of the invention is a ship's propulsion arrangement and a bearing arrangement in the ship's propulsion unit, as well as a bearing arrangement. Supported against the ship's hull, there is a propulsion unit, inside which there is an electric motor that drives the ship's propeller, whereby the rotor of the electric motor is connected to the propeller shaft (14). The propeller shaft (14) is supported onto the propulsion unit's frame with the first bearing (18) between the rotor's first end and the propeller, and with the second bearing (34) between the second rotor end and the shaft end opposite to the propeller. The first (18) and the second (34) bearings are radial bearings executed with rolling bearings. At least one bearing (36) executed as a slide bearing supporting the shaft (14) in the axial direction is fitted on the propeller shaft (14).
