Waterproof sliding bearing for warship

Abstract

The invention discloses a waterproof sliding bearing for a warship. The waterproof sliding bearing comprises a bearing cover, a bearing seat, an oppositely-opened bearing bush and a rotating shaft. The bearing cover and the bearing seat are fixedly connected through double-head studs at the tops; an oil hole is formed in the middle of the bearing cover; the oppositely-opened bearing bush is fixedly arranged between the bearing cover and the bearing seat, and oil storage tanks are arranged between the oppositely-opened bearing bush and the bearing cover as well as between the oppositely-openedbearing bush and the bearing seat; a plurality of bush holes are formed in the positions, on the two sides of the vertical direction of the oil hole, of the oppositely-opened bearing bush correspondingly; and the rotating shaft is arranged in the oppositely-opened bearing bush, and a sealing gasket is arranged in the position, close to the oppositely-opened bearing bush, of the rotating shaft. Thesealing gasket and a protection box are arranged on the suitable positions, the oppositely-opened bearing bush in the sliding bearing is polished, and thus the waterproof effect is achieved while theworking efficiency of the sliding bearing is not affected.

Description

technical field [0001] The invention relates to the field of sliding bearings, in particular to a waterproof sliding bearing for ships. Background technique [0002] Sliding bearings are bearings that work under sliding friction. Sliding bearings work smoothly, reliably and without noise. Under the condition of liquid lubrication, the sliding surface is separated by lubricating oil without direct contact, which can also greatly reduce friction loss and surface wear. The oil film also has a certain ability to absorb vibration. There are many types of sliding bearings, which can be divided according to the direction that can bear the load. There are two types of radial (central) sliding bearings and thrust (axial) sliding bearings. The application of sliding bearings is generally under low-speed and heavy-load conditions, or operating parts that are difficult to maintain and add lubricating oil. Sliding bearing wear generally adopts methods such as repair welding, bushing, an...

Problems solved by technology

[0003] However, in equipment operating at sea such as ships, the wide application of sliding bearings is different from that in dry environments. Because the settings and machines on ships are often in contact with water, sliding bearings will also wear out after a long period of use, resulting in Poor sealing, so that water enters the bearing, the consequences of this situation can be large or small, so it needs to be solved urgently
