Embodiment Construction
[0015] In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings. Such as figure 1 As shown, the present invention provides an integrated sealing device suitable for the stern shaft of a ship. All parts of the device are arranged coaxially with the stern shaft, which mainly includes the direction from where the propeller of the hull is to where the power components of the hull are located. The inflatable partition sealing part, the sealing rotating part, the sealing static part and the emergency sealing part are set on the outside of the stern shaft in sequence. The sealing rotating part cooperates with the sealing static part to form a mechanical seal against seawater. When the stern shaft is working, the sealing rotating part follows the movement of the stern shaft, and the sealing end face of the sealing rotating part and the sealing end face of the sealing static part form a friction pair; whe...

The invention provides an integrated sealing device applicable to a stern shaft. The integrated sealing device is characterized by comprising an inflation partition sealing component, a sealing rotation component, a sealing static component and an emergency sealing component which are sheathed outside the stern shaft in sequence in from the direction in which a propeller of a ship is to the direction in which the power component of the ship is. The integrated sealing device can absorb outside vibration, oscillation, slanting and impact to a greater extent. According to the invention, the sealing rotation component, the sealing static component, the inflation partition sealing component and the emergency sealing component are integrated, thus being capable of fast, simply and conveniently replacing and installing the integrated sealing device. Device maintenance and replacement can be carried out on the sea through the inflation partition sealing component, and longer parking time can be delayed and wined over through the emergency sealing component when a main seal does not work.
Description
technical field [0001] The invention relates to a sealing device used on the stern shaft of a ship. Background technique [0002] With the rapid development of global economic integration, the exchange of goods between various countries is becoming more and more frequent. Due to the large throughput of cargo ships and the lower cost compared with air transportation, shipping has become the main mode of transportation of goods between countries. At the same time, in order to meet people's different living needs, large cruise ships and even private cruise ships are also developing rapidly. [0003] Whether it is a cargo ship or a cruise ship, it is often necessary to carry out long-distance transoceanic voyages. During the voyage, it is necessary to resist various adverse environmental factors. Therefore, there are higher requirements for the technical specifications of the hull. The stern shaft is a device connecting the propeller and power components, and its sealing perfo...
