A radial bearing with an auxiliary oil inlet plate

Abstract

A radial bearing bush equipped with an auxiliary oil inlet plate includes multiple radial bearing bush bodies arranged at intervals along the circumference of a rotating shaft. An auxiliary oil inlet plate is provided on each radial bearing bush body. A strip-shaped oil groove is provided on the inner side of the auxiliary oil inlet plate, and an oil inlet and an oil outlet are connected to the strip-shaped oil groove. The oil outlets are arranged at intervals along the length of the strip-shaped oil groove, and are positioned between the radial bearing bush body and the rotating shaft. This invention uses an auxiliary oil inlet plate to increase the lubricating oil supply, allowing the lubricating oil to be more evenly distributed between the radial bearing bush body and the rotating shaft. The strip-shaped oil groove and oil outlet guide the lubricating oil to cover the working area of ​​the bearing bush, preventing oil shortage and forming a dense oil film between the radial bearing bush body and the journal, significantly reducing friction, reducing wear, and extending the bearing bush's service life. This invention can also guide more low-temperature lubricating oil into the bearing bush, accelerating heat transfer.

Description

Technical Field

[0001] This utility model belongs to the field of radial bearing technology, specifically relating to a radial bearing equipped with an auxiliary oil inlet plate. Background Technology

[0002] When a sliding bearing is in operation, a thin oil film is required between the bearing shell and the shaft for lubrication to reduce friction and wear. Currently, an oil supply system is used, consisting of an oil groove in the bearing shell and an oil injection hole. However, this system results in uneven distribution of lubricating oil between the bearing shell and the shaft, leading to poor lubrication. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, the technical solution adopted by this utility model is: a radial bearing bush equipped with an auxiliary oil inlet plate, comprising a plurality of radial bearing bush bodies arranged sequentially at intervals along the circumferential direction of the rotating shaft, an auxiliary oil inlet plate being provided on the radial bearing bush body, a strip-shaped oil groove being provided on the inner side of the auxiliary oil inlet plate, an oil inlet and an oil outlet being connected to the strip-shaped oil groove, the oil outlet being arranged sequentially at intervals along the length direction of the strip-shaped oil groove, and the oil outlet being connected to the oil inlet space formed between the radial bearing bush body and the rotating shaft.

[0005] The oil inlet is connected to the middle of the strip-shaped oil trough, forming an independent oil supply circuit.

[0006] The diameter of the oil inlet is larger than the diameter of the oil outlet.

[0007] The auxiliary oil inlet plate is provided with mounting holes, and bolts are inserted into the mounting holes to fix the auxiliary oil inlet plate to the radial bearing body.

[0008] Compared with existing technologies, this invention has the following advantages: The auxiliary oil inlet plate increases the lubricating oil supply, allowing for a more even distribution of lubricating oil between the radial bearing body and the shaft. Its strip-shaped oil grooves and outlet guide the lubricating oil to cover the working area of ​​the bearing, preventing oil shortage and forming a dense oil film between the radial bearing body and the journal, significantly reducing friction, wear, and extending the bearing's service life. This invention also guides more low-temperature lubricating oil into the bearing, accelerating heat transfer. A large amount of cold oil quickly removes the heat generated by friction in the bearing, effectively reducing its temperature and preventing damage due to overheating, ensuring the equipment operates within its normal temperature range.

[0012] To make the objectives, technical solutions, and advantages of this application clearer, the application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application.

[0013] Conversely, this application covers any alternatives, modifications, equivalent methods, and schemes made within the spirit and scope of this application as defined by the claims. Furthermore, to provide the public with a better understanding of this application, certain specific details are described in detail below. However, this application can be fully understood by those skilled in the art even without these detailed descriptions.

[0014] See Figures 1-3 A radial bearing bush equipped with an auxiliary oil inlet plate includes a plurality of radial bearing bush bodies 3 arranged sequentially at intervals along the circumference of a rotating shaft 1. An auxiliary oil inlet plate 2 is provided on the radial bearing bush body 3. A strip-shaped oil groove 201 is provided on the inner side of the auxiliary oil inlet plate 2. An oil inlet 202 and an oil outlet 203 are connected to the strip-shaped oil groove 201. The oil outlet 203 is arranged sequentially at intervals along the length of the strip-shaped oil groove 201. The oil outlet 203 is connected to the oil inlet space formed between the radial bearing bush body 3 and the rotating shaft 1.

[0015] The oil inlet 202 is connected to the middle part of the strip-shaped oil trough 201.

[0016] The diameter of the oil inlet 202 is larger than the diameter of the oil outlet 203.

[0017] The auxiliary oil inlet plate 2 is provided with mounting holes 204, and the auxiliary oil inlet plate 2 is fixed to the radial bearing body 3 by inserting bolts through the mounting holes.

[0018] An auxiliary oil inlet plate is installed on one side of the bearing bush. The oil inlet plate has an independent oil outlet and a strip-shaped oil groove. When the bearing rotates, it guides the lubricating oil to flow along a predetermined path. The oil outlet and the strip-shaped oil groove form a "branched oil supply", guiding the lubricating oil to diffuse towards the edge of the working surface. The auxiliary oil inlet plate body is made of metal, with an oil inlet and a strip-shaped oil groove on the inner side of the plate. The oil inlet is located on the side of the auxiliary oil inlet plate closest to the lubricating oil source and is connected to an external oil supply pipe. The diameter and spacing of the oil outlet are changed and selected according to the size of the bearing bush, "draining" the lubricating oil in the strip-shaped oil groove to both sides of the axial direction.

[0019] The auxiliary oil inlet plate is equipped with mounting holes and is fixed to the non-primary load-bearing area of ​​the bearing bush by bolts. The curvature of the oil inlet plate side is the same as that of the wedge-shaped side of the bearing bush, which increases the load-bearing area of ​​the bearing bush.

[0020] This invention employs an auxiliary oil inlet plate to increase the lubricating oil supply, allowing the lubricating oil to be more evenly distributed between the bearing and the shaft. Its strip-shaped oil grooves and oil outlets guide the lubricating oil to cover the working area of ​​the bearing, preventing oil shortage and forming a dense oil film between the bearing and the journal, significantly reducing friction, minimizing wear, and extending the bearing's service life.

[0021] This invention guides more low-temperature lubricating oil into the bearing bush, accelerating heat transfer. A large amount of cold oil quickly removes the heat generated by friction in the bearing bush, effectively reducing its temperature and preventing damage due to overheating, thus ensuring the equipment operates within its normal temperature range.

[0022] Under special operating conditions such as equipment startup, shutdown, or sudden load changes, the oil film between the bearing and the shaft is easily damaged. The auxiliary oil inlet plate can quickly replenish the lubricating oil, maintain the thickness and stability of the oil film, avoid direct contact between the bearing and the shaft, and protect the bearing surface.

[0023] The auxiliary oil inlet plate, through its specific inlet and flow channel design, guides the lubricating oil along a predetermined path, enabling it to reach the parts requiring lubrication and cooling more efficiently. This avoids oil waste and disordered flow, improving the utilization rate of the lubricating oil. Simultaneously, it allows cold oil to enter the wedge-shaped oil film area directly without mixing, separating hot oil from the sliding surface and improving the efficiency of cold oil heat exchange.

[0024] The structure is relatively simple to design. During installation, it only needs to be fixed to one side of the bearing and the oil supply pipeline connected, requiring minimal modification to the existing equipment. Moreover, during equipment maintenance, inspection and maintenance are relatively convenient, allowing direct inspection of the oil inlet plate's fixation and whether the oil passage is blocked, facilitating timely detection and resolution of problems.
