Description

Technical Field

[0001] The utility model relates to the technical field of shaft sleeves, in particular to a double-base self-lubricating shaft sleeve. Background Art

[0002] Self-lubricating bushings are special bearings that are filled with lubricants such as grease or oil. During operation, the lubricant enters the friction surface through the internal micropores or grooves, forming a lubricating film that effectively reduces the friction coefficient, reduces friction losses, and increases the service life and operating efficiency of the bearing.

[0003] However, the existing self-lubricating bushing structure is relatively simple, generally a simple sleeve structure with micropores or grooves on the surface of the sleeve structure. However, the existing self-lubricating bushing has limited anti-deformation effect and will be completely scrapped if damaged, which needs further optimization.

[0004] Therefore, the present application provides a double-base self-lubricating sleeve to solve the above technical problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a double-base self-lubricating shaft sleeve to solve the problem in the prior art that the existing self-lubricating shaft sleeve has limited anti-deformation effect and is easily scrapped after being damaged.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A double-base self-lubricating sleeve comprises a sleeve body, a surface of which is provided with a plurality of self-lubricating micropores, an upper base and a lower base being fixed to the upper and lower ends of the sleeve body, a top of the lower base being provided with a plurality of snap-fit ​​grooves surrounding the lower end of the sleeve body, a protective plate being elastically inserted into the snap-fit ​​groove, and the protective plate being arranged in close contact with the outer edge of the sleeve body;

[0008] An oil storage cavity is provided inside the protective plate, a docking hole for docking with the self-lubricating microhole is provided on the inner side of the protective plate, the docking hole is communicated with the inside of the oil storage cavity, and an opening of the oil storage cavity is provided on the top of the protective plate.

[0009] Optionally, flanges are fixed to the ends of the upper base and the lower base away from the sleeve body.

[0010] Optionally, a movable piece is elastically installed in the clamping groove, and the movable piece elastically abuts against the bottom of the protective plate upward.

[0011] Optionally, a plurality of springs are fixed to the lower end surface of the movable piece, and the springs are installed at the bottom of the clamping groove.

[0012] Optionally, a buckle groove is fixed to the bottom of the protection plate, and the buckle groove is inserted into the snap-fit ​​groove.

[0013] Optionally, a positioning portion is fixed to the top of the protection plate, and the positioning portion is inserted into the bottom of the upper base.

[0014] Optionally, a plurality of the protection plates are tightly arranged around the outer edge surface of the sleeve body, and buckle grooves are provided on the outer sides of the tops of the protection plates.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] In the above scheme, thanks to the setting of the sleeve body, upper base, lower base and protective plate, multiple protective plates can be detachably installed on the outer edge surface of the sleeve body to form protection, thereby reducing the situation where the sleeve body is damaged and directly scrapped. After the protective plate is damaged, it is convenient to replace it individually, which can increase the service life of the device.

[0017] In the above scheme, thanks to the setting of the protective plate, the oil storage chamber and the docking hole, the oil storage chamber can be used to store the lubricating liquid, and the docking hole and the self-lubricating micropores can be used to dock and immerse the lubricating liquid into the inner wall of the sleeve body to achieve the self-lubricating effect. In addition, the detachable setting of the protective plate also makes it convenient to add lubricating oil to the oil storage chamber later.

[0018] In summary, the device not only has a good anti-deformation effect, but also is convenient for replenishing self-lubricating oil, and has a good overall use effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a double-base self-lubricating sleeve, including a sleeve body 1, a surface of which is provided with a plurality of self-lubricating micropores 101, an upper base 2 and a lower base 3 are fixed to the upper and lower ends of the sleeve body 1 respectively, and a flange 4 is fixed to the end of the upper base 2 and the lower base 3 away from the sleeve body 1 for easy installation.

[0033] The top of the lower base 3 is provided with a plurality of engaging grooves 5 surrounding the lower end of the sleeve body 1. A protective plate 7 is elastically inserted into the engaging groove 5. The protective plate 7 is arranged in close contact with the outer edge of the sleeve body 1. The plurality of protective plates 7 are arranged in close contact around the outer edge of the sleeve body 1, and a buckle groove 701 is provided on the outer side of the top of the protective plate 7. Specifically, a movable piece 6 is provided in the engaging groove 5. The lower end surface of the movable piece 6 is fixed with a plurality of springs 601. The springs 601 are installed in the bottom of the engaging groove 5 to form an elastic installation. The movable piece 6 elastically abuts the bottom of the protective plate 7 upward, thus forming an elastic installation for the protective plate 7.

[0034] Cooperate Figure 3 and Figure 4 As shown, an oil storage chamber 8 is provided inside the protective plate 7, and a docking hole 9 for docking with the self-lubricating micropore 101 is provided on the inner side of the protective plate 7. The docking hole 9 is communicated with the inside of the oil storage chamber 8, and an opening of the oil storage chamber 8 is provided on the top of the protective plate 7, so that lubricating oil can be stored in the oil storage chamber 8 and immersed in the inner wall of the sleeve body 1 to form a self-lubricating effect.

[0035] In this embodiment, a buckle groove 701 is fixed on the bottom of the protection plate 7, and the buckle groove 701 is inserted into the clamping groove 5, and a positioning portion 703 is fixed on the top of the protection plate 7, and the positioning portion 703 is inserted into the bottom of the upper base 2.

[0036] The working principle provided by the present invention is that the double-base self-lubricating sleeve can be detachably mounted on the outer edge surface of the sleeve body 1 by inserting the clamping portion 702 into the clamping groove 5 and then inserting the positioning portion 703 into the bottom of the upper base 2 when in use. Therefore, by detachably mounting multiple protective plates 7 on the outer edge surface of the sleeve body 1 to form protection, the situation in which the sleeve body 1 is directly scrapped due to damage can be reduced, and the protective plates 7 can be easily replaced individually after being damaged, which is convenient to use.

[0037] The protective plate 7 can also use the oil storage chamber 8 to store lubricating liquid, and use the docking hole 9 to dock with the self-lubricating micropores 101 to immerse the lubricating liquid into the inner wall of the sleeve body 1 to achieve a self-lubricating effect. In addition, the detachable setting of the protective plate 7 also makes it convenient to add lubricating oil to the oil storage chamber 8 later.

[0038] In summary, the device not only has a good anti-deformation effect, but also is convenient for replenishing self-lubricating oil, and has a good overall use effect.

[0039] This invention encompasses any alternatives, modifications, equivalents, and solutions that do not depart from the spirit and scope of this invention.
