Technical Field

The invention relates to the technical field of ships, in particular to an upper rudder bearing, a rudder system and a ship.

Background

The rudder system is an important device for changing or maintaining the sailing direction of a ship and mainly comprises a rudder blade, a rudder stock, an upper rudder bearing, a lower rudder bearing and the like. The upper rudder bearing mainly bears radial load caused by hydrodynamic force acting on a rudder blade and axial load caused by the gravity of a rudder system, and is an important component for ensuring the safe operation of the rudder system.

In recent years, the requirements of energy conservation and environmental protection of ships are increasing. The efficient rudder has the advantages that the maneuverability of a ship can be guaranteed, the resistance is smaller, the propulsion efficiency can be improved, particularly, the twisted rudder can be matched with a propeller, and the effect of improving the propulsion efficiency and reducing the cavitation corrosion phenomenon is good. Therefore, efficient rudders are becoming more and more favored by boat owners.

The prior high-efficiency rudder product is generally that a rudder blade, a rudder stock sleeve, an upper rudder bearing and a lower rudder bearing are integrally designed, manufactured and installed. Because the rudder blade and the false rudder of the efficient rudder are both thin, the diameter of a rudder stock sleeve is smaller, the size of a conventional plane friction watertight upper rudder bearing is very large, the conventional upper rudder bearing is usually required to be bored on the site of a shipyard, the installation period of a rudder system is prolonged, the conventional upper rudder bearing is used, the rudder stock is required to be lengthened, the rudder stock of the efficient rudder is usually made of alloy steel, and the corresponding cost is also greatly increased. The rudder rotor is therefore usually equipped with a lower-lying rudder carrier.

In order to ensure the normal operation of the rudder system, the upper rudder bearing and the lower rudder bearing of the high-efficiency rudder need to have extremely high coaxiality. The sunken upper rudder bearing body is embedded in the rudder stock sleeve, and in order to guarantee the axiality, the high requirement has been proposed to the installation accuracy of sleeve, rudder stock and upper rudder bearing, and the installation degree of difficulty is very high. In addition, when the sealing member is changed in the maintenance of sunken rudder carrier later stage, need hang out the whole of rudder carrier body, the degree of difficulty is very big.
