Description

Technical Field

[0001] The utility model relates to the field of bearing sleeves, in particular to an easily disassembled corrosion-resistant bearing sleeve. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy; the sleeve is a sleeve used on the shaft or bearing. The sleeve is generally used on the gear shaft or bearing, and its main function is to fix and position.

[0003] According to a Chinese patent with announcement number CN216306496U, a waterproof, corrosion-resistant and anti-falling bearing sleeve is disclosed. The utility model is provided with a rubber ring at the top of the sleeve, which can act as a sealing ring to prevent water from flowing into the inner cavity from the top of the sleeve, so as to avoid rusting of the bearing and increased rotational resistance. At the same time, a bottom plate is also provided under the sleeve to avoid water seepage under the sleeve, thereby protecting the internal bearing.

[0004] In view of the above-mentioned disclosed patent content, a rubber ring is provided and the inner wall of the rubber ring is closely fitted with the outer wall of the shaft rod, so as to seal the end of the sleeve and prevent water from penetrating into the interior of the sleeve through the top of the sleeve. However, the rubber ring will age after long-term use, making it difficult to closely fit with the outer wall of the shaft rod, thereby reducing the sealing between the shaft rod and the top of the sleeve. Therefore, the rubber ring needs to be replaced after a period of use in order to improve the sealing between the shaft rod and the sleeve. However, since the rubber ring is sleeved on the outer wall of the shaft rod, it needs to be removed from the shaft rod when replaced. However, the disassembly process is relatively cumbersome. If other components are installed on the shaft rod, it is difficult to remove and replace the rubber ring, thereby reducing the efficiency of disassembly and replacement of the rubber ring. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide an easily disassembled corrosion-resistant bearing sleeve to solve the technical problem of inconvenience in disassembling and replacing the rubber ring.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an easily removable corrosion-resistant bearing sleeve, comprising a chassis and an inner sleeve, the inner sleeve being provided with a disassembly assembly, and the disassembly assembly comprises slide grooves opened on both sides of the top of the inner sleeve and a limit sleeve sleeved on the outer wall of the inner sleeve, a spring is installed on one side of the inner side of the slide groove, and a slider is connected to one end of the spring, a gasket is installed on the top of the two sliders, an annular groove is opened on the top of the gasket, and a swivel is arranged inside the annular groove, a protective sleeve is installed on the top of the swivel, and a slot is opened on one side of the inner side of the protective sleeve, and an insert block is inserted into the inside of the slot, one side of the insert block is connected to a mounting ring, and one side of the mounting ring is provided with a sealing ring, and one side of the slider is provided with a pressure rod penetrating to the outside of the inner sleeve.

[0007] By adopting the above technical solution, when the sealing ring needs to be replaced, the limiting sleeve can be rotated so that the limiting sleeve no longer fits the pressure rod. At this time, the spring contracts, thereby driving the slider to reset and move.

[0008] Furthermore, second magnetic blocks are installed on the upper and lower parts of the interior of the protective sleeve, and first magnetic blocks are provided on the upper and lower parts of the outer wall of the mounting ring, and the first magnetic blocks correspond to the second magnetic blocks one by one.

[0009] By adopting the above technical solution, when the first magnetic block and the second magnetic block are attached and adsorbed, the mounting ring can be limited to prevent the mounting ring from moving at will or falling off from the protective cover.

[0010] Furthermore, a shaft sleeve is threadedly connected to the top of the chassis, and a sleeve is installed on the top of the shaft sleeve.

[0011] By adopting the above technical solution, the threaded connection between the shaft sleeve and the base plate facilitates the disassembly and assembly of the shaft sleeve, and the arrangement of the sleeve facilitates the installation of the inner liner.

[0012] Furthermore, an inner liner is connected to the inner thread of the sleeve, and an axial hole is opened at the middle position of the top of the sleeve.

[0013] By adopting the above technical solution, when installing the inner bushing, the inner bushing can be rotated and screwed into the interior of the sleeve, thereby completing the installation of the inner bushing.

[0014] Furthermore, a bearing seat is provided on the top of the chassis, and an inner cavity is opened in the sleeve.

[0015] By adopting the above technical solution, the bearing can be installed in the inner cavity, and the sleeve can protect the bearing.

[0016] Furthermore, mounting holes are provided on both sides of the top of the chassis.

[0017] By adopting the above technical solution, the setting of the mounting hole makes it easy to install the shaft sleeve and also makes it convenient to remove the shaft sleeve later.

[0018] Furthermore, the outer wall of the inner bushing and the inner wall of the limiting sleeve are both provided with threads, and the limiting sleeve is threadedly connected to the inner bushing.

[0019] By adopting the above technical solution, when the staff rotates the limit sleeve, the limit sleeve can move so that the limit sleeve contacts or does not contact the pressure rod.

[0020] Furthermore, one end of the pressure rod is in contact with the inner wall of the limiting sleeve.

[0021] By adopting the above technical solution, the limiting sleeve can limit the pressure rod to prevent the pressure rod from moving at will.

[0022] Furthermore, the protective sleeve and the gasket ring are both slidably connected to the slide groove via a slider.

[0023] By adopting the above technical solution, when the slider slides inside the slide groove, it will drive the protective sleeve and the gasket to move, so that the two protective sleeves are opened or closed.

[0024] Furthermore, the two sealing rings, the two mounting rings and the two protective sleeves are tightly fitted, and the mounting rings and the sealing rings are detachably connected to the protective sleeves.

[0025] By adopting the above technical solution, the sealing performance between the sealing ring, the mounting ring and the protective sleeve can be improved, and the sealing ring and the mounting ring can be removed from the protective sleeve so that the sealing ring can be replaced.

[0026] In summary, the utility model mainly has the following beneficial effects:

[0027] The utility model is provided with a disassembly component. When the sealing ring needs to be replaced, the limiting sleeve can be rotated so that the limiting sleeve is no longer in contact with the pressure rod. At this time, the spring contracts, thereby driving the slider to reset and move. The slider drives the gasket ring and the protective sleeve to move, and drives the sealing ring to move, so that the two sealing rings are separated and no longer in contact with the outer wall of the shaft. At this time, the installation ring can be pushed by the push block to separate the first magnetic block from the second magnetic block, and the insert block is moved out of the slot. Then the installation ring and the sealing ring can be removed, so that it is convenient to replace the worn or aged sealing ring. When installing the sealing ring and the installation ring, Insert the plug on one side of the new sealing ring into the slot, and fit the first magnetic block and the second magnetic block. At this time, the installation of the mounting ring and the sealing ring can be completed. Then press the pressure rod to make the slider drive the protective sleeve to move, and drive the sealing ring to move. When the two sealing rings, the mounting ring and the protective sleeve are closed, the sealing ring can fit with the outer wall of the shaft, so as to seal. In this way, the two sealing rings can be quickly disassembled and assembled to replace the sealing rings, avoid the worn or aged sealing rings from being used continuously to reduce the sealing between the shaft and the sleeve, and prevent water from seeping into the sleeve from above.

[0040] See also Figure 1-Figure 4 The disassembly component 9 includes a slide groove 901 opened on both sides of the top of the inner sleeve 4 and a limit sleeve 904 sleeved on the outer wall of the inner sleeve 4, a spring 902 is installed on one side of the inner side of the slide groove 901, and one end of the spring 902 is connected to a slider 905, and a gasket 906 is installed on the top of the two sliders 905, one side of the two gaskets 906 is fitted together, and an annular groove 908 is opened on the top of the gasket 906, and a swivel 907 is arranged inside the annular groove 908, the outer wall of the inner sleeve 4 and the inner wall of the limit sleeve 904 are both provided with threads, and the limit sleeve 904 is threadedly connected to the inner sleeve 4, so that when the staff rotates the limit sleeve 904, the limit sleeve 904 can move, so that the limit sleeve 904 contacts or does not contact the pressure rod 903.

[0041] Specifically, the protective sleeve 914 and the gasket ring 906 are slidably connected to the slide groove 901 through the slider 905. When the slider 905 slides inside the slide groove 901, it will drive the protective sleeve 914 and the gasket ring 906 to move, so that the two protective sleeves 914 are opened or closed, and the two sealing rings 5, the two mounting rings 911 and the two protective sleeves 914 are tightly fitted, thereby improving the sealing between the shaft rod and the inner bushing 4, preventing water from flowing into the shaft sleeve 3 from the gap between the inner bushing and the shaft rod, thereby improving the waterproof performance and corrosion resistance of the shaft sleeve. The mounting ring 911 and the sealing ring 5 are detachably connected to the protective sleeve 914 to improve the sealing ring 5, the mounting ring 911 and the protective sleeve 914. The sealing between them is improved. At the same time, the sealing ring 5 and the mounting ring 911 can be removed from the protective sleeve 914 so that the sealing ring 5 can be replaced. The swivel ring 907 is slidably connected with the annular groove 908, so that the swivel ring 907 can slide inside the annular groove 908. The sealing ring 5 is made of rubber material.

[0045] See also Figure 7A second magnetic block 910 is installed on the upper and lower parts of the protective cover 914, and a first magnetic block 909 is installed on the upper and lower parts of the outer wall of the mounting ring 911. The first magnetic block 909 corresponds to the second magnetic block 910 one by one. When the first magnetic block 909 and the second magnetic block 910 are fitted and adsorbed, the mounting ring 911 can be limited to prevent the mounting ring 911 from moving at will or falling off from the protective cover 914.

[0046] The working principle of the utility model is as follows: first, the staff can install the bearing on the bearing seat 7, then install the sleeve 3 on the chassis 1, and install the inner sleeve 4 on the sleeve 8. When the sealing ring 5 needs to be replaced, the limiting sleeve 904 can be rotated so that the limiting sleeve 904 is no longer in contact with the pressure rod 903. At this time, the spring 902 contracts, thereby driving the slider 905 to reset and move. The slider 905 drives the gasket ring 906 and the protective sleeve 914 to move, and drives the sealing ring 5 to move, so that the two sealing rings 5 ​​are separated and no longer in contact with the outer wall of the shaft. At this time, the installation ring 911 can be pushed by the push block to separate the first magnetic block 909 from the second magnetic block 910, and at the same time, the plug block 913 is moved out of the slot 912. After that, the mounting ring 911 and the sealing ring 5 can be removed, so as to facilitate the replacement of the worn or aged sealing ring 5. When installing the sealing ring 5 and the mounting ring 911, the plug 913 on one side of the new sealing ring 5 is inserted into the slot 912, and the first magnetic block 909 and the second magnetic block 910 are fitted together.
