Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ship rudder bearing installation, in particular to a ship rudder bearing installation structure. Background Art
[0002] The ship rudder bearing installation structure is the main structure on the ship to bear the axial and radial loads of the rudder stock and rudder blade. The connection of the rudder bearing ensures that the rudder blade can rotate with the rudder stock so as to control the turning and driving direction of the ship. The installation of the rudder bearing can also effectively prevent water from entering the ship through the gap between the rudder stock and the ship when the ship is traveling on the water, thereby improving the sealing of the ship.
[0003] Publication No.: CN220465772U discloses a ship rudder bearing installation structure. The patent improves the sealing effect by setting a sealing rubber ring between the cover plate and the support plate, but also makes the sealing rubber ring exposed. Since the sealing rubber ring is mostly made of rubber material, it is easy for seawater to contact the rubber ring if it is exposed for a long time, thereby causing erosion and cracking of the rubber ring, thereby affecting the sealing effect of the rubber ring. Therefore, we introduce a ship rudder bearing installation structure. Utility Model Content
