Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of rudder bearings, and particularly relates to a high-sealing multi-point quantitative lubrication rudder bearing. Background Art
[0002] A rudder bearing refers to a bearing device installed between the rudder shaft and the rudder stock of a ship, which is used to support and reduce the friction of the rudder, enabling the rudder shaft to rotate freely inside the rudder stock. The rudder bearing is usually made of wear-resistant materials such as bronze, copper alloy or polymer to ensure good wear resistance and long service life. Its main function is to reduce the frictional resistance of the rudder shaft during operation, thereby improving the operation flexibility and accuracy of the rudder, and at the same time protecting the rudder shaft from wear.
[0003] For the existing rudder bearings, it is necessary to maintain appropriate lubrication during operation to reduce friction and wear. However, most of the existing lubrication devices cannot evenly distribute the lubricant to the internal structure of the rudder bearing, which may lead to insufficient lubrication in some parts and excessive lubrication in other parts, thus affecting the normal operation of the rudder shaft and the rudder bearing. Moreover, the rudder bearing will come into contact with seawater during operation, which may cause lubricant leakage. This will not only increase costs but also may pollute the surrounding environment.
[0004] Therefore, we provide a high-sealing multi-point quantitative lubrication rudder bearing to solve the above problems. Content of the Utility Model
