Description

Technical Field

[0001] The utility model relates to a sealed dustproof oil-containing bearing, in particular to a sealed dustproof oil-containing bearing, and belongs to the technical field of dustproof oil-containing bearings. Background Art

[0002] Bearings are important basic components of various mechanical equipment. They are components that fix and reduce the load friction coefficient during mechanical transmission. In other words, when other parts move relative to each other on the shaft, they are used to reduce the friction coefficient during power transmission and keep the center position of the shaft fixed. Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies and reduce the mechanical load friction coefficient of the equipment during transmission. According to the different friction properties of the moving elements, since bearings are high-precision components, dustproof structures are usually set on the bearings to prevent dust from entering the interior of the bearings.

[0003] The existing sealed dust-proof oil-containing bearing structure is fixed. The dust-proof structure on the bearing is usually installed by using glue or other sticky materials on both sides of the bearing to seal the bearing to achieve the dust-proof effect. However, after long-term use, the glue may fall off due to the heat generated by the bearing. The fallen glue residue may fall into the inside of the bearing, affecting the normal operation of the bearing, and it is also troublesome to disassemble when the sealing ring is damaged.

[0004] Therefore, there is an urgent need to improve a sealed dust-proof oil-containing bearing to solve the above-mentioned problems. Utility Model Content

[0005] The utility model aims to provide a sealed dustproof oil-containing bearing. By providing a dustproof structure, the traditional method of installing the dustproof pad using glue or other sticky materials is changed, so that the bearing outer ring can be installed quickly and have a good dustproof effect. First, multiple dustproof pads are clamped on the outer side of the retaining frame. Multiple second balls on the dustproof pads are attached to the inner wall of the bearing outer ring and can rotate with the bearing outer ring when the bearing outer ring rotates. The clamping block can be clamped inside the through hole under the elastic action of the spring. When the clamping block is clamped inside the through hole, it will not extend into the inner ring of the bearing inner ring, so as not to affect the installation of the bearing inner ring. After the multiple clamping blocks are clamped, the dustproof pad can be fixed to seal the interior of the bearing outer ring, thereby preventing dust from entering. When the dustproof pad is removed, the multiple clamping blocks are pressed to shrink them into the interior of the mounting hole, so that the dustproof pad can be removed. After the dustproof pad is worn and cannot be used, it can be removed in time, thereby avoiding the traditional glue connection method that causes glue residue to fall into the interior of the bearing outer ring and does not affect the normal operation of the bearing.

[0006] In order to achieve the above-mentioned purpose, the main technical solutions adopted by this utility model include:

[0007] A sealed dustproof oil-containing bearing comprises a bearing outer ring and a bearing inner ring, a retaining frame is installed inside the bearing inner ring, a plurality of first balls are installed on the retaining frame, a dustproof structure is provided on the bearing outer ring, the dustproof structure comprises two dustproof pads installed on both sides of the bearing outer ring, the outer ring of the dustproof pad is installed with a plurality of second balls connected to the inner wall of the bearing outer ring, the inner ring of the dustproof pad is provided with a plurality of mounting holes, a spring is fixedly installed inside the mounting hole, a clamping block is fixedly installed at one end of the spring, and a plurality of through holes adapted to the clamping block are provided on the bearing outer ring.

[0013] Preferably, the outer side of the dustproof pad is coated with a wear-resistant coating.

[0014] The utility model has at least the following beneficial effects:

[0015] By setting up the dustproof structure, the traditional method of installing the dustproof gasket using glue or other sticky materials is changed, so that the outer ring of the bearing can be installed quickly and have a good dustproof effect. First, multiple dustproof gaskets are clamped on the outside of the retaining frame. The multiple second balls on the dustproof gasket will fit on the inner wall of the outer ring of the bearing and can rotate with it when the outer ring of the bearing rotates.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] like Figure 1-Figure 5 As shown, this embodiment provides an embodiment of a sealed dust-proof oil-containing bearing.

[0025] A sealed dustproof oil-containing bearing comprises a bearing outer ring 1 and a bearing inner ring 2, a retaining frame 3 is installed inside the bearing inner ring 2, a plurality of first balls 4 are installed on the retaining frame 3, a dustproof structure 5 is provided on the bearing outer ring 1, the dustproof structure 5 comprises two dustproof pads 6 installed on both sides of the bearing outer ring 1, the outer ring of the dustproof pad 6 is installed with a plurality of second balls 7 connected to the inner wall of the bearing outer ring 1, a plurality of mounting holes 8 are provided on the inner ring of the dustproof pad 6, a spring 9 is fixedly installed inside the mounting hole 8, a clamping block 10 is fixedly installed at one end of the spring 9, a plurality of through holes 11 adapted to the clamping block 10 are provided on the bearing outer ring 1, and the setting of the dustproof structure 5 changes the traditional method of using glue or other sticky materials to install the dustproof pad 6, so that the bearing outer ring 1 can be installed quickly and have a good dustproof effect. First, the plurality of dustproof pads are fixedly installed. The dust pad 6 is stuck on the outside of the retaining frame 3, and the multiple second balls 7 on the dust pad 6 will fit on the inner wall of the bearing outer ring 1 and can rotate with the bearing outer ring 1 when it rotates. The clamping block 10 can be clamped into the inside of the through hole 11 under the elastic action of the spring 9. When the clamping block 10 is clamped into the inside of the through hole 11, it will not extend into the inner ring of the bearing inner ring 2, so as not to affect the installation of the bearing inner ring 2. After the multiple clamping blocks 10 are clamped, the dust pad 6 can be fixed to seal the inside of the bearing outer ring 1, thereby preventing dust from entering. When the dust pad 6 is removed, the multiple clamping blocks 10 are pressed to shrink them to the inside of the mounting hole 8, and the dust pad 6 can be removed. The dust pad 6 can be removed in time after it is worn and cannot be used, thereby avoiding the traditional glue connection method that causes glue residue to fall into the inside of the bearing outer ring 1, which will not affect the normal operation of the bearing.

[0026] like Figure 3 As shown, a notch is provided at one end of the block 10. The notch at one end of the block 10 allows the hand to exert force conveniently when pressing the block 10, thereby saving effort when removing the dustproof pad 6.

[0027] like Figure 4As shown, a lubricating oil filling port 12 is provided on the bearing outer ring 1, and a plug 13 is installed on the lubricating oil filling port 12. A limiting plate 14 is fixedly installed on the bottom of the plug 13. A limiting groove 15 adapted to the limiting plate 14 is provided on the bearing outer ring 1. Through the arrangement of the lubricating oil filling port 12, the plug 13, the limiting plate 14 and the limiting groove 15, the lubricating oil inside the bearing outer ring 1 can be added in time when it is insufficient, without the need to disassemble the dustproof pad 6, thereby saving the time of adding lubricating oil. After the addition is completed, the limiting plate 14 is aligned with the limiting groove 15 and inserted to the plug 13 on the bearing outer ring 1 to seal it. The plug 13 is an embedded installation method and will not affect the operation of the bearing.

[0028] like Figure 4 As shown, a filter screen 16 is provided inside the lubricating oil filling port 12, a first magnetic ring 17 is fixedly installed on the top of the filter screen 16, and a second magnetic ring 18 magnetically connected to the first magnetic ring 17 is fixedly installed on the inner wall of the lubricating oil filling port 12. Through the arrangement of the filter screen 16, the first magnetic ring 17 and the second magnetic ring 18, the lubricating oil can be filtered to prevent impurities in the oil from entering the interior of the bearing outer ring 1. When the impurities accumulate too much, it will affect the rotation of the first ball 4, and the bearing outer ring 1 may be damaged over time.

[0029] like Figure 2 As shown, a magnetic sealing ring 19 is installed on the inner wall of the bearing inner ring 2, and an anti-slip ring 20 is installed inside the magnetic sealing ring 19. Through the arrangement of the magnetic sealing ring 19 and the anti-slip ring 20, the magnetic sealing ring 19 is installed on the inner side of the bearing inner ring 2 to seal the through hole 11 on the bearing inner ring 2, preventing dust from entering the interior of the through hole 11 through the through hole 11, and then the anti-slip ring 20 is fixed inside the magnetic sealing ring 19. Due to the material properties of the anti-slip ring 20, when the bearing inner ring 2 is connected to other workpieces, the connection between the two can be prevented from sliding, thereby improving the stability of the connection of the bearing inner ring 2.

[0030] like Figure 5 As shown, one end of the anti-slip ring 20 is fixedly installed with a Velcro surface 21, and the other end of the anti-slip ring 20 is fixedly installed with a Velcro thorn surface 22 adhered to the Velcro surface 21. Through the arrangement of the Velcro surface 21 and the Velcro thorn surface 22, the disconnection design of the anti-slip ring 20 can facilitate the installation of the anti-slip ring 20 on the inner side of the magnetic sealing ring 19. After the installation is completed, the Velcro surface 21 and the Velcro thorn surface 22 are adhered together to make the anti-slip ring 20 in a closed loop state, thereby avoiding the disconnection of the anti-slip ring 20 when the bearing inner ring 2 is in use, which may affect the stability of the bearing inner ring 2.

[0031] like Figure 2As shown, the outer side of the dustproof pad 6 is coated with a wear-resistant coating 23. The provision of the wear-resistant coating 23 can reduce the wear of the dustproof pad 6 during use, thereby increasing the service life of the dustproof pad 6.

[0032] In this embodiment, if Figure 1-Figure 5 As shown, the working process of a sealed dustproof oil-containing bearing provided in this embodiment is as follows:

[0033] First, multiple dust-proof pads 6 are clamped on the outside of the retaining frame 3. The multiple second balls 7 on the dust-proof pad 6 will fit on the inner wall of the bearing outer ring 1 and can rotate with the bearing outer ring 1 when it rotates. The clamping block 10 can be clamped inside the through hole 11 under the elastic action of the spring 9. When the clamping block 10 is clamped inside the through hole 11, it will not extend to the inner ring of the bearing inner ring 2 to avoid affecting the installation of the bearing inner ring 2. After the multiple clamping blocks 10 are clamped, the dust-proof pad 6 can be fixed to seal the inside of the bearing outer ring 1, thereby preventing dust from entering. When the dust-proof pad 6 is removed, the multiple clamping blocks 10 are pressed to shrink them to the inside of the mounting hole 8, and the dust-proof pad 6 can be removed. The dust-proof pad 6 can be removed in time after it is worn and cannot be used, thereby avoiding the traditional glue connection method that causes glue residue to fall into the inside of the bearing outer ring 1, which will not affect the normal operation of the bearing.

[0034] In summary, in this embodiment, according to a sealed dust-proof oil-containing bearing of this embodiment, the notch at one end of the clamping block 10 is provided, so that the hand can be conveniently exerted when pressing the clamping block 10, thereby making it easier for personnel to remove the dust-proof pad 6. By providing the lubricating oil filling port 12, the plug 13, the limiting plate 14 and the limiting groove 15, the lubricating oil inside the bearing outer ring 1 can be added in time when it is insufficient, without the need to disassemble the dust-proof pad 6, thereby saving the time of adding lubricating oil. After the addition is completed, the limiting plate 14 is aligned with the limiting groove 15 and the plug 13 can be replaced on the bearing outer ring 1 to seal it. The embedded installation method of the plug 13 will not affect the operation of the bearing. The setting of the filter 16, the first magnetic ring 17 and the second magnetic ring 18 can filter the lubricating oil to prevent impurities in the oil from entering the interior of the bearing outer ring 1. When the impurities accumulate too much, it will affect the rotation of the first ball 4, and the bearing outer ring 1 may be damaged for a long time. The setting of the ring 19 and the anti-slip ring 20, installing the magnetic sealing ring 19 to the inner side of the bearing inner ring 2 can seal the through hole 11 on the bearing inner ring 2, preventing dust from entering the inside of the through hole 11 through the through hole 11, and then fixing the anti-slip ring 20 to the inside of the magnetic sealing ring 19. Due to the material characteristics of the anti-slip ring 20, the connection between the bearing inner ring 2 and other workpieces can be prevented from sliding, thereby improving the stability of the connection of the bearing inner ring 2. Through the setting of the Velcro fur surface 21 and the Velcro thorn surface 22, the disconnection design of the anti-slip ring 20 can facilitate the installation of the anti-slip ring 20 on the inner side of the magnetic sealing ring 19. After the installation is completed, the Velcro fur surface 21 and the Velcro thorn surface 22 are glued together to make the anti-slip ring 20 in a closed loop state, thereby avoiding the anti-slip ring 20 disconnecting when the bearing inner ring 2 is in use, which affects the stability of the bearing inner ring 2. Through the setting of the wear-resistant coating 23, the wear of the dustproof pad 6 during use can be reduced, thereby improving the service life of the dustproof pad 6.
