Description

Technical Field

[0001] The invention belongs to the field of marine rudder bearings and rudder stocks, and particularly relates to a layered lubrication type marine rudder bearing and rudder stock structure. Background Art

[0002] The rudder bearing is an important device in the ship's rudder system. The rudder bearing bears the axial and radial loads from the rudder stock and the rudder blade to ensure that the rudder blade rotates left and right with the rudder stock, thereby changing the ship's course or keeping the ship sailing in a straight line. In the current connection structure between the rudder stock and the rudder bearing, a sealing sleeve is generally arranged in the rudder bearing. The rudder stock generally rotates and passes through the sealing sleeve. Due to the lack of lubrication during the long-term friction between the sealing sleeve and the rudder stock, wear will occur, which not only accelerates the wear and damage of the rudder stock, affects the service life of the rudder stock, but also gradually loses the sealing effect as the wear gap increases. Seawater is very likely to erode the rudder stock and its rudder bearing parts, shortening the service life of the rudder stock and reducing the load-bearing capacity of the rudder bearing. Therefore, it is necessary to improve the lubrication performance of the rudder stock and the sealing sleeve. However, when the connection between the rudder stock and the sealing sleeve is relatively tight, the lubricating oil cannot automatically penetrate from top to bottom, or the penetration speed is extremely slow, and good lubrication cannot be achieved. At the same time, when not in use, the lubricating oil is easily lost additionally. Therefore, it is necessary to upgrade the structure. Summary of the Invention
