[0002] A bearing is a mechanical component that is typically used to support rotating shafts or rotors and reduce friction and wear, thereby enabling machinery to operate smoothly and efficiently. Existing bearings generally consist of an outer ring, an inner ring, a cage, and rolling elements. The setting of the fixed body reduces the friction between the outer ring and the inner ring.

[0003] According to the bearing disclosed in application number CN201420034699.9, the key technical points of the bearing solution are: it includes an outer ring, an inner ring, a cage, and rolling elements. The rolling elements are fixed between the outer ring and the inner ring by the cage. The outer ring and the inner ring are respectively provided with a first raceway and a second raceway for the rolling elements to roll. Annular bearing caps are provided on both sides between the outer ring and the inner ring. The inner ring includes an inner ring body and several mounting blocks evenly distributed along the center of the inner ring body. An annular groove is provided on the outer circumference of the inner ring body, and a notch is provided on the annular groove for placing the mounting blocks. The mounting blocks are all placed in the annular groove and are detachably fixedly connected to the inner ring body. Each mounting block forms an arc-shaped surface on the opposite side of the inner ring body. Any adjacent mounting blocks are in contact with each other. Each arc-shaped surface is connected in sequence to form the second raceway. This utility model has the advantages of facilitating the replacement and maintenance of the rolling elements and the inner ring, and reducing manufacturing costs.

[0004] Based on the above, in the current bearing usage process, when the equipment stops running, the lubricating oil used to lubricate the bearing will flow back into the lubrication box. When the equipment is restarted, there will be a certain time interval when the lubricating oil lubricates the bearing, making it difficult to lubricate the bearing in a timely manner and affecting the service life of the bearing. Utility Model Content

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0024] Example 1: As shown in the attached document Figures 1-5 As shown:

[0025] This utility model provides a bearing with automatic lubrication function, including an inner ring 1, rollers 2, an outer ring 3, a fixed cage 4, a sliding cage 5, and a lubrication mechanism; multiple rollers 2 are arranged in a circumferential array on the outside of the inner ring 1, and the multiple rollers 2 are rotatably connected to the outside of the inner ring 1; the outer ring 3 is rotatably connected to the outside of the multiple rollers 2; the fixed cage 4 covers the outside of the multiple rollers 2; multiple sliding cages 5 are arranged in a circumferential array on the outside of the fixed cage 4, and the multiple sliding cages 5 are all slidably connected to the outside of the fixed cage 4; the lubrication mechanism is arranged on the inside of the fixed cage 4.

[0026] The lubrication mechanism includes: a protrusion 201, a lubrication cavity 202, a lubrication pipe 203, a limiting groove 6, and an exchange hole 601. Multiple sets of protrusions 201 are fixedly connected to the outer sides of multiple rollers 2. Multiple lubrication cavities 202 are provided, each located inside the multiple rollers 2. Multiple sets of lubrication pipes 203 are provided, each located inside the multiple rollers 2, and each connected to a lubrication cavity 202. Two sets of limiting grooves 6 are provided, one set located inside the fixed retainer 4, and the other set located inside the multiple sliding retainers 5. Two sets of exchange holes 601 are provided, one set located inside the fixed retainer 4, and the other set located inside the multiple sliding retainers 5.

[0027] The specific usage and function of this embodiment are as follows: During equipment operation, the lubricating oil in the equipment enters the limiting groove 6 through the exchange hole 601. Part of the lubricating oil entering the limiting groove 6 will lubricate the roller 2, and the other part will flow into the lubrication chamber 202 for storage through the lubrication pipe 203. When the equipment stops running, the lubricating oil on the outside of the roller 2 will flow back into the lubrication box. When the equipment is restarted, the lubricating oil in the lubrication box is difficult to lubricate the roller 2 immediately. At this time, the lubricating oil in the lubrication chamber 202 will flow out through the lubrication pipe 203 under the action of centrifugal force to lubricate the roller 2. By setting the limiting groove 6, the range of motion of the roller 2 can be limited.

[0028] Example 2: Based on Example 1, such as Figure 6As shown, it also includes a replacement mechanism, a slide groove 401, a sliding rod 501, a return spring 502, a limiting groove 503, a sliding frame 7, a limiting rod 701, and a compression spring 8; the replacement mechanism is located inside the fixed retainer 4; multiple sets of slide grooves 401 are provided, all of which are located inside the fixed retainer 4; multiple sets of sliding rods 501 are provided, each of which is fixedly connected to the outside of multiple sliding retainers 5, and all of which are slidably connected to the inside of the fixed retainer 4; multiple sets of return springs 502 are provided, and all of which are fixedly connected to the fixed retainer 4. On the outside of the fixed retainer 4, multiple sets of return springs 502 abut against the outside of multiple sets of sliding rods 501; multiple sets of limiting grooves 503 are provided, and the multiple sets of limiting grooves 503 are respectively opened on the inside of the multiple sets of sliding rods 501; multiple sets of sliding frames 7 are provided, and the multiple sets of sliding frames 7 are all slidably connected to the inside of the fixed retainer 4; multiple sets of limiting rods 701 are provided, and the multiple sets of limiting rods 701 are respectively fixedly connected to the inside of the multiple sets of sliding frames 7; multiple sets of compression springs 8 are provided, and the multiple sets of compression springs 8 are respectively fixedly connected to the outside of the multiple sets of sliding frames 7, and the multiple sets of compression springs 8 are fixedly connected to the inside of the fixed retainer 4.

[0029] The specific usage and function of this embodiment are as follows: When one of the rollers 2 is worn out or damaged, the sliding bracket 7 can be pressed down to disengage the limiting rod 701 from the limiting groove 503. At this time, the sliding retainer 5 can be pulled to open it. The damaged roller 2 can then be removed and replaced with a new roller 2. After the replacement is completed, the sliding retainer 5 will be reset under the action of the return spring 502. At this time, the sliding bracket 7 will be compressed by the spring 8 to insert the limiting rod 701 into the inner side of the limiting groove 503, thereby limiting the sliding retainer 5 and realizing the installation of the roller 2.
