Description

Technical Field

[0001] This utility model relates to the field of bearings, and in particular to a lubricated bearing. Background Technology

[0002] Bearings are essential components in modern industry, mainly consisting of an inner ring and an outer ring, with a cage and balls positioned between them. During operation, the balls rotate relative to the inner and outer rings, generating friction. Therefore, proper lubrication is crucial. A common lubrication method involves adding lubricating oil to the center of the inner and outer rings. To prevent external dust from entering the bearing, baffles are typically installed between the inner and outer rings, and the positions of the oil filling holes on the bearing are fixed. However, in the lubrication process, lubricating oil applied to a single location cannot adequately coat all the outer walls of the balls, resulting in poor lubrication. Therefore, we have designed a lubricated bearing. Summary of the Invention

[0003] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a lubricated bearing that can effectively solve the problem that existing bearings usually have a baffle between the inner and outer rings to prevent external dust from entering the bearing, and the position of the oil injection hole on the bearing is also fixed. However, in the lubrication process, the lubricating oil in a single location cannot be fully coated on the outer wall of all the balls, resulting in poor lubrication effect.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A lubricated bearing includes an outer ring and an inner ring disposed inside the outer ring;

[0006] In addition, a mounting ring is fixedly installed on the inner side of the outer ring in a ring-shaped structure. The outer wall of the mounting ring has multiple guide grooves in a ring-shaped structure, and also includes an oil injection hole that penetrates the outer wall of the outer ring. The position of the oil injection hole corresponds to the guide groove.

[0007] It also includes a mounting bracket disposed between the middle of the outer ring and the inner ring, with the ball bearings sleeved on the mounting bracket. A mounting block is also disposed on the inner side of the mounting ring, with the outer wall of the mounting block overlapping the outer wall of the ball bearings.

[0008] Preferably, an annular groove is formed on the outer circumferential wall of the inner ring, the outer wall of the annular groove slides in fit with the outer wall of the ball, and a plurality of first magnetic rings are arranged in an annular shape at equal intervals on the outer circumferential wall of the inner ring.

[0009] Preferably, two adjacent guide grooves are kept in communication through a connecting groove, and the guide groove is further provided with a through hole fixedly formed therethrough, the lower end of which is located on the inner surface of the mounting block.

[0010] Preferably, a circular groove is formed on the lower outer wall of the mounting block, the outer wall of the ball overlaps with the inner wall of the circular groove, and sponge blocks are fixedly connected to both sides of the mounting block, and the through hole is in communication with the inside of the sponge block, and ribs are provided on the outer wall of the sponge block.

[0011] Preferably, it further includes a second magnetic ring movably connected to both sides of the mounting ring, the second magnetic ring being magnetically attracted to the first magnetic ring, and the outer wall of the second magnetic ring being in compressive contact with the rib.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention, by setting multiple guide grooves on the mounting ring and connecting the through hole with the sponge block on the side wall of the mounting block, allows lubricating oil to be quickly applied to the outer wall of the balls when the bearing is in use, achieving efficient lubrication, reducing wear, and ensuring normal bearing operation.

The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0027] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are merely simplified descriptions for the convenience of describing this invention and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this invention.

[0028] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number. Example

[0029] See attached document Figure 1-5 As shown, a lubricated bearing includes an outer ring 100 and an inner ring 200 disposed inside the outer ring 100; it also includes a mounting bracket 400 disposed between the middle of the outer ring 100 and the inner ring 200, and balls 410 are sleeved on the mounting bracket 400. Specifically, in this application, a plurality of balls 410 are arranged in a ring structure between the middle of the outer ring 100 and the inner ring 200, and are fixed by the mounting bracket 400. An annular groove 201 is formed on the outer circumferential wall of the inner ring 200, and the outer wall of the annular groove 201 slides in fit with the outer wall of the balls 410. During actual use, the balls 410 will rotate within the mounting bracket 400, and the outer wall of the balls 410 will also roll within the annular groove 201, ensuring the normal use of the bearing.

[0030] Furthermore, it also includes a mounting ring 300 fixedly installed in a ring shape on the inner side of the outer ring 100. A mounting block 310 is also provided on the inner side of the mounting ring 300, and the outer wall of the mounting block 310 overlaps with the outer wall of the ball 410. In particular, a circular groove 313 is formed on the lower outer wall of the mounting block 310, and the outer wall of the ball 410 overlaps with the inner wall of the circular groove 313. In actual use, it maintains communication with the connecting groove 302. It also includes a through hole 303 fixedly formed in the guide groove 301, and the lower outlet of the through hole 303 is located on the inner surface of the mounting block 310.

[0031] Specifically, after the bearing has been used for a period of time, a certain amount of lubricating oil is injected into the middle of the outer ring 100 and the mounting ring 300 through the oil injection hole 101 that is opened through the outer ring 100. With the help of the guide groove 301 that is opened in a ring shape on the outer wall of the mounting ring 300, when the lubricating oil is injected into the guide groove 301 through the oil injection hole 101, the corresponding lubricating oil will flow along the guide groove 301 to the entire guide groove 301. Furthermore, with the connection between the multiple guide grooves 301 through the connecting groove 302, each guide groove 301 can allow the lubricating oil to flow, so as to achieve uniform addition of lubricating oil.

[0032] Furthermore, in this application, a plurality of first magnetic rings 210 are arranged in a ring at equal intervals on the outer circumference of the inner ring 200, and a second magnetic ring 320 is movably connected to both sides of the mounting ring 300. The second magnetic ring 320 and the first magnetic ring 210 are magnetically attracted to each other. Sponge blocks 311 are fixedly connected to both sides of the mounting block 310, and the through holes 303 are in communication with the interior of the sponge blocks 311. Ribs 312 are provided on the outer wall of the sponge blocks 311, and the outer wall of the second magnetic ring 320 is in compressive contact with the ribs 312. Specifically, when the bearing is in actual use, due to the fixed connection between the inner ring 200 and the external connecting shaft, the inner ring 200 will rotate relative to the outer ring 100. During this process, the magnetic attraction force between the first magnetic ring 210 and the second magnetic ring 320 will continuously change. At this time, the second magnetic ring 320 movably connected to the mounting ring 300 will continuously move towards the axis of the bearing.

[0033] In this situation, the ribs 312 on the sponge block 311 on the outer wall of the mounting block 310 will be continuously squeezed by the second magnetic ring 320. With the connection between the through hole 303 and the sponge block 311, the lubricating oil adsorbed in the sponge block 311 will be continuously squeezed out from its interior and placed inside the circular groove 313. Combined with the contact relationship between the outer wall of the ball 410 and the circular groove 313, the lubricating oil can quickly immerse the entire ball 410. In particular, when in use, the ball 410 is in a rotating state. In this case, the lubricating oil can be efficiently coated on the surface of the ball 410 to ensure the normal use of the bearing.

[0034] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations of the embodiments of the present invention may be made without departing from the stated principles.
