When enough lubricating oil is added, oil injection is stopped, the bowl-shaped metal sheet is reset, the oil injection hole in the middle of the bowl-shaped metal sheet is connected with the sealing cover, sealing of the oil injection pipe is achieved, negative pressure is formed in the bearing bush when the oil is consumed up, and therefore the bowl-shaped metal sheet is driven to bulge upwards to remind workers to supplement the hydraulic oil in time, and the service life of the bearing bush is prolonged. Compared with an existing bearing bush, the oil injection hole can be sealed when lubricating oil in the bearing bush is full, and the oil injection hole is opened when oil consumption is completed, so that hydraulic oil is reminded to be supplemented in time.

Description

Technical Field

[0001] The utility model relates to the technical field of bearing bushes, in particular to a marine bearing bush with good lubricity. Background Art

[0002] The bearing shell, also called "shaft liner", is the contact and connection part between the sliding bearing and the shaft neck. When the sliding bearing is working, a very thin oil film is required between the bearing shell and the rotating shaft for lubrication. If the lubrication is poor, there will be direct friction between the bearing shell and the rotating shaft. The friction will generate very high temperature and easily cause damage to the shaft, so the rotating shaft and the bearing shell need to be fully lubricated.

[0003] Chinese utility model patent, CN201921998777.6, a highly lubricated bearing, has an inner wall of the bearing that opens a hole on the surface of the bearing to inject lubricating oil into the oil groove inside the bearing. However, this solution makes it difficult to determine whether the lubricating oil inside the bearing is sufficient, and the lubricating oil cannot be replenished in time, and the oil inlet is not sealed, which makes the lubricating oil easy to leak.

[0004] Therefore, how to provide a marine bearing with good lubricity to solve the problems existing in the prior art is of great significance to its application. Utility Model Content

[0005] In view of this, the purpose of the present application is to provide a marine bearing with good lubricity to solve the problem in the prior art that it is difficult to judge whether the lubricating oil inside the bearing is sufficient and the lubricating oil cannot be replenished in time.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A marine bearing with good lubricity comprises an upper bearing member and a lower bearing member, the inner walls of the upper bearing member and the lower bearing member are provided with a plurality of lubricating oil grooves, the middle parts of the lubricating oil grooves are connected by an oil distribution groove, the top end of the upper bearing member and the bottom end of the lower bearing member are provided with connecting holes, and the top end of the upper bearing member and the bottom end of the lower bearing member are fixedly connected with oil filling pipes.

[0008] Preferably, both ends of the upper bearing shell component and both ends of the lower bearing shell component are fixedly connected with connecting ears, and the surfaces of the connecting ears are provided with fixing holes.

[0009] Preferably, the oil filling pipe is communicated with the connecting hole, a bowl-shaped metal sheet and a fixing rod are fixedly connected to the inside of the oil filling pipe, and a sealing cover is fixedly connected to the middle of the fixing rod.

[0010] Preferably, an oil filling hole is opened at the center of the bowl-shaped metal sheet, the diameter of the oil filling hole is smaller than the diameter of the sealing cover, and the shape of the sealing cover is bowl-shaped.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] When the utility model replenishes lubricating oil, the oil from the oil filling pipe is pressed inwardly due to the large oil inlet pressure, causing the oil filling hole to separate from the sealing cover, and the external lubricating oil enters the connecting hole through the oil filling hole, and then the oil is added. When enough lubricating oil is added, the oil filling is stopped and the bowl-shaped metal sheet is reset, so that the oil filling hole in the middle of the bowl-shaped metal sheet is connected to the sealing cover, so as to achieve the sealing of the oil filling pipe. When the oil is consumed, negative pressure is formed inside the bearing shell, thereby driving the bowl-shaped metal sheet to bulge, reminding the staff to replenish the hydraulic oil in time. Compared with the existing bearing shell, the utility model can seal the oil filling hole when the lubricating oil inside the bearing shell is full, and open it when the oil consumption is complete, reminding the staff to replenish the hydraulic oil in time.
