摘要： This invention relates to lip seals for shafts, whose lip bodies consist of rubber elastic material, and is mounted on the reverse side on an essentially radial surface of a back-up ring which is integral with the housing. When the pressure of the medium to be sealed out increases, dangerous overloads occur on the lip edge, in spite of the roller diaphragm-like deformation of the lip body. According to the invention, these overloads are reduced by the introduction of a trough in the supporting back-up ring in the zone of the lip body near the clamp, into which the lip body is deformed and thus the pressure on the edge of the lip is reduced (FIG. 1 ).

摘要： A ship, in particular a deep-draft vessel configured for travel on the oceans or great lakes, can have a hull with two concentrically rotating propeller shafts passing through the hull, and rotate in opposite directions to one another. The ship will generally have seals between the propeller shafts, and between the propeller shafts and the hull. In general, it is necessary to lubricate and cool the sealing surfaces of the individual seals, so that the useful life of the individual seals is prolonged, and the risk of failure of the seals is reduced. For the effective lubrication of highly-stressed seals of propeller drive systems for ships with two concentric propellers rotating in opposite directions, a forced feed lubrication system with circulating lubricating oil has been found to be advantageous.

摘要： The invention employs the principle of the prior art for cooling a heated body by means of so-called heat pipes, with seal devices for rotating shafts, in particular for a ship's propeller shaft. According to this principle, an externally closed chamber extending in the longitudinal direction and filled with a liquid working fluid extends on one end into the body to be cooled, and on the other end into a cold medium, whereby a constant circulation takes place, so that the work fluid is evaporated in the hot portion of the chamber, the vapor flows into the cold portion of the chamber, condenses there, and the condensate is returned to the hot portion by way of a capillary structure (FIG. 1 ).

摘要： There is now provide an ocean-going ship, and an ocean-going vessel with a stern tube seal arrangement for sealing a stern tube for a propeller drive shaft, and an arrangement for sealing propeller drive shafts in an ocean-going vessel. In the seal arrangement there is provided a compensation to balance pressure fluctuations that arise in the lubricating oil chamber due to axial oscillations of the shaft. In this, the change of pressure is determined by a sensor and this actual value is passed to a comparator element. The comparator element controls a pressure valve so as to control the extent of filling of an annular tubular expandable body, whereby the expandable body impacts on the lubricating oil chamber. By way of a phase shift of 180 degrees in reference to the sensed pressure impulse in the event of an increase in volume of the expandable body, a minimized pressure fluctuation in the lubricating oil chamber can be controlled.
