[0018] Preferably, the first clamping assembly comprises a socket and a plug rod, the socket is arranged on the groove wall of the rotating ring groove, the plug rod is integrally formed on the top of the rotating insertion plate in a vertical direction, and the plug rod is inserted into the socket.

[0019] By adopting the technical scheme, the hole wall side of the insertion hole limits the insertion rod, thereby effectively ensuring the stability of the shaft sleeve in the assembly cavity.

[0020] Preferably, the second clamping assembly comprises a mounting groove and a magnet, the bottom of the inner wall of the outer ring of the composite sleeve is recessed in a direction away from the shaft sleeve, and a mounting groove is also formed on the side of the shaft sleeve connected to the outer ring, and a magnet is bonded in the mounting groove of the shaft sleeve and the outer ring.

[0021] By adopting the technical scheme, as the shaft sleeve rotates in the assembly cavity, when the magnet on the shaft sleeve and the magnet on the outer ring of the composite sleeve rotate together and are magnetically connected, the magnet on the shaft sleeve and the magnet on the outer ring of the composite sleeve are used to limit the shaft sleeve and the outer ring of the composite sleeve, and in this state, the four first oil injection holes and the four second oil injection holes are aligned and connected.

[0022] Furthermore, when it is necessary to fill lubricating oil into the bearing, when the magnet on the shaft sleeve and the magnet on the outer ring of the composite sleeve rotate together and are magnetically connected, it means that the first oil injection hole on the outer ring of the composite sleeve and the corresponding second oil injection hole on the shaft sleeve are in a state of communication, thereby assisting the staff to quickly and efficiently align the first oil injection hole and the second oil injection hole, which is beneficial to improve the convenience and experience of work.

At this time, the lubricating oil can be added to the oil outlet hole through the first oil injection hole and the second oil injection hole, and filled to the bearing through the oil outlet hole.

[0032] Since the oil outlet holes are uniformly spaced and distributed on the inner ring of the composite sleeve, these oil outlet holes can uniformly provide lubrication to the bearing in multiple directions, which is beneficial to ensure the lubrication effect of the bearing during operation.

[0033] This kind of setting method opens the oil outlet hole on the inner ring of the composite sleeve, effectively avoids opening the oil hole directly on the bearing sleeve, thereby ensuring the lubrication effect of the bearing while not damaging the structural strength of the bearing sleeve, thereby effectively ensuring the stability of the bearing system as a whole during operation of the bearing.

In this state, the four first oil injection holes and the four second oil injection holes are aligned and connected.

[0035] Further, when the magnet on the shaft sleeve and the magnet on the composite sleeve outer ring rotate together and are magnetically connected, it means that the first oil injection hole on the composite sleeve outer ring and the corresponding second oil injection hole on the shaft sleeve are in a state of continuous communication, which can help workers to quickly and efficiently align the first oil injection hole and the second oil injection hole, and is beneficial to improve the convenience and experience of work.

After the sleeve 1 and the composite sleeve 2 are assembled, the corresponding bearing is inserted into the inner ring 21 of the composite sleeve 2, and a corresponding sealing cover is additionally arranged at the bottom of the sleeve 1 to effectively seal the sleeve 1, the composite sleeve 2 and the bearing.

The second oil injection hole 5 is in communication with the oil outlet hole 6.

[0048] When it is not necessary to add lubricating oil into the bearing, the first oil injection hole 4 and the second oil injection hole 5 are misaligned with each other, at this time, the first oil injection hole 4 and the second oil injection hole 5 are not in communication with each other, and the second oil injection hole 5 and the oil outlet hole 6 are also not in communication with each other; when it is necessary to add lubricating oil into the bearing to lubricate the bearing, the sleeve 1 is rotated in the assembly cavity 3 until the first oil injection hole 4 and the second oil injection hole 5 are aligned with each other and in communication with each other, at this time, the second oil injection hole 5 and the corresponding oil outlet hole 6 are also aligned and in communication with each other. At this time, the lubricating oil can be added into the oil outlet hole 6 through the first oil injection hole 4 and the second oil injection hole 5, and filled into the bearing through the oil outlet hole 6.

[0049] Since the oil outlet holes 6 are uniformly distributed on the entire inner ring 21 of the composite sleeve 2, the oil outlet holes 6 can uniformly provide lubrication for the bearing in multiple directions, which is beneficial to guarantee the lubrication effect of the bearing during operation.

[0050] The oil outlet holes 6 are arranged on the inner ring 21 of the composite sleeve 2, which effectively avoids directly arranging the oil holes on the bearing sleeve, thereby guaranteeing the lubrication effect of the bearing and not damaging the structural strength of the bearing sleeve, thereby effectively guaranteeing the stability of the bearing system as a whole during operation of the bearing.

[0051] In the embodiment, the first oil injection holes 4 and the second oil injection holes 5 are both provided as four, the four first oil injection holes 4 are distributed at four positions of front, back, left and right of the outer ring 22 of the composite sleeve 2, and the four second oil injection holes 5 are distributed at four positions of front, back, left and right of the shaft sleeve 1. The first oil injection holes 4 and the second oil injection holes 5 are provided as multiple, which not only can quickly and effectively fill the lubricating oil to the shaft sleeve 1 through the oil outlet hole 6, but also can effectively guarantee the uniformity in the filling process of the lubricating oil, and is beneficial to improve the lubricating effect of the lubricating oil on the bearing.

[0052] Meanwhile, referring to FIGS. 2, 3 and 4, the shaft sleeve 1 and the composite sleeve 2 are further provided with a clamping mechanism, the clamping mechanism includes a first clamping assembly 9 and a second clamping assembly 10, the first clamping assembly 9 is used for stably installing the shaft sleeve 1 in the assembly cavity 3, and the second clamping assembly 10 is used for assisting the workers to quickly and efficiently align the first oil injection holes 4 and the second oil injection holes 5, thereby effectively improving the convenience and experience of work.

[0053] Specifically, referring to FIG. 1, the bottom of the connecting ring 23 is recessed in the direction away from the assembly cavity 3 along the circumferential side to form a rotating ring groove 7 for the rotation of the shaft sleeve 1, and the rotating ring groove 7 is located in the assembly cavity 3. The top of the shaft sleeve 1 is integrally formed with a rotating plug 8 in the vertical direction along the circumferential side, the rotating plug 8 is inserted into the rotating ring groove 7 and rotates in the rotating ring groove 7.

[0054] The rotating ring groove 7 and the rotating plug 8 are used to realize the rotation of the shaft sleeve 1 in the assembly cavity 3, and then the opening or closing of the first oil injection holes 4 and the second oil injection holes 5 is realized by rotating the shaft sleeve 1.

[0055] Specifically, referring to FIGS. 1, 2 and 3, the first clamping assembly 9 includes a plug hole 91 and a plug rod 92. The plug hole 91 is formed on the groove wall of the rotating ring groove 7, and the plug rod 92 is integrally formed on the top of the rotating plug 8 in the vertical direction. The plug rod 92 rotates in the rotating ring groove 7 along with the rotating plug 8, until the top of the plug rod 92 is inserted into the plug hole 91. The plug hole 91 is used to limit the plug rod 92 in a certain direction, thereby effectively guaranteeing the stability of the installation of the shaft sleeve 1 in the assembly cavity 3.

[0056] When the plug rod 92 is inserted into the plug hole 91, the first oil injection holes 4 and the second oil injection holes 5 are kept in a state of misalignment and mutual disconnection.

[0057] In the embodiment, the material of the plug rod 92 is rubber material. The rubber material has soft texture, elasticity and easy deformation. When the shaft sleeve 1 needs to be rotated, the plug rod 92 can easily deform and slide out of the plug hole 91, so as to release the limitation of the plug hole 91 on the plug rod 92.

[0058] At the same time, specifically in processing, the length of the insertion rod 92 and the depth of the insertion hole 91 are reasonably controlled, and the depth of the insertion rod 92 inserted into the insertion hole 91 is not too deep when the insertion rod 92 is inserted into the insertion hole 91, which can help the insertion rod 92 to slide out of the insertion hole 91, but it is ensured that the insertion rod 92 can be limited.

[0059] Specifically, referring to FIGS. 1 and 4, the second clamping assembly 10 includes a mounting groove 101 and a magnet 102. The bottom of the inner wall of the outer ring 22 of the composite sleeve 2 is recessed in a direction away from the shaft sleeve 1, and a mounting groove 101 is formed on the side of the shaft sleeve 1 connected to the outer ring 22 of the composite sleeve 2, and the magnet 102 is adhered in the mounting groove 101 by adhesive mounting. When the shaft sleeve 1 rotates in the assembly cavity 3, when the magnet 102 on the shaft sleeve 1 and the magnet 102 on the outer ring 22 of the composite sleeve 2 rotate together and are magnetically connected, the magnet 102 on the shaft sleeve 1 and the magnet 102 on the outer ring 22 of the composite sleeve 2 are used to limit the shaft sleeve 1 and the outer ring 22 of the composite sleeve 2. In this state, the four first oil injection holes 4 and the four second oil injection holes 5 are aligned and connected.

[0060] Further, when it is necessary to fill lubricating oil into the bearing, when the magnet 102 on the shaft sleeve 1 and the magnet 102 on the outer ring 22 of the composite sleeve 2 rotate together and are magnetically connected, it means that the first oil injection hole 4 on the outer ring 22 of the composite sleeve 2 and the corresponding second oil injection hole 5 on the shaft sleeve 1 are in a state of continuous communication, which can assist the worker to quickly and efficiently align the first oil injection hole 4 and the second oil injection hole 5, and is beneficial to improve the convenience and experience of work.

[0061] The implementation principle of the bearing sleeve in the embodiment of the application is:

[0062] When it is not necessary to add lubricating oil into the bearing, the first oil injection hole 4 and the second oil injection hole 5 are misaligned with each other, at this time, the first oil injection hole 4 and the second oil injection hole 5 are in a state of mutual disconnection; when it is necessary to add lubricating oil into the bearing to lubricate the bearing, the shaft sleeve 1 is rotated in the assembly cavity 3 until the first oil injection hole 4 and the second oil injection hole 5 are aligned and connected. At this time, the lubricating oil can be added to the oil outlet hole 6 through the first oil injection hole 4 and the second oil injection hole 5, and filled into the bearing through the oil outlet hole 6.

[0063] Since the oil outlet holes 6 are evenly spaced and cover the entire inner ring 21 of the composite sleeve 2, these oil outlet holes 6 can uniformly provide lubrication to the bearing in multiple directions, which is beneficial to ensure the lubrication effect of the bearing during operation.

[0064] The oil outlet hole 6 is arranged on the inner ring 21 of the composite sleeve 2, which effectively avoids the direct arrangement of the oil hole on the bearing sleeve, thereby ensuring the lubrication effect of the bearing and not damaging the structural strength of the bearing sleeve, thereby effectively ensuring the stability of the bearing system during the operation of the bearing.

[0065] Embodiment 2:

[0066] The difference between the embodiment of the present application and embodiment 1 is that:

[0067] Referring to FIGS. 1 and 5, the second clamping assembly 10 includes a first clamping groove 103 and a second clamping groove 104. The first clamping groove 103 is in a strip shape and is integrally formed on the bottom of the outer ring 22 of the composite sleeve 2 in the horizontal direction. A strip-shaped clamping block 11 is slidably installed in the first clamping groove 103 in the length direction thereof. The second clamping groove 104 is arranged on the outer wall of the shaft sleeve 1.

[0068] When the shaft sleeve 1 rotates in the assembly cavity 3 and the second clamping groove 104 on the shaft sleeve 1 corresponds to the first clamping groove 103 on the outer ring 22 of the composite sleeve 2, the clamping block 11 in the first clamping groove 103 extends from the first clamping groove 103 into the second clamping groove 104. The second clamping groove 104 on the shaft sleeve 1 and the clamping block 11 on the outer ring 22 of the composite sleeve 2 are used to limit the shaft sleeve 1 and the outer ring 22 of the composite sleeve 2. In this state, the four first oil injection holes 4 and the four second oil injection holes 5 are aligned and connected in communication.

[0069] After the filling of the lubricating oil is completed, the clamping block 11 is slid out of the second clamping groove 104, and the shaft sleeve 1 is rotated again to insert the insertion rod 92 into the insertion hole 91. At this time, the first oil injection hole 4 and the corresponding second oil injection hole 5 remain in a misaligned state.

[0070] Specifically, referring to FIG. 5, a spring 12 is installed on the first clamping groove 103 in the length direction thereof. One end of the spring 12 is connected to the inner wall of the first clamping groove 103, and the other end of the spring 12 is connected to the clamping block 11. The spring 12 is compressed and elastic to realize the sliding of the clamping block 11 in the first clamping groove 103.

[0071] Specifically, when the bearing does not need to be filled with lubricating oil, the insertion rod 92 is inserted into the insertion hole 91. At this time, the shaft sleeve 1 is in a stable installation state. At this time, the outer wall of the shaft sleeve 1 presses the clamping block 11, and the spring 12 is compressed in this state. With the rotation of the shaft sleeve 1, when the clamping block 11 aligns with the second clamping groove 104 on the shaft sleeve 1, the spring 12 pushes the clamping block 11 into the second clamping groove 104 by relying on the elastic force of the spring 12, thereby realizing the clamping of the clamping block 11 into the second clamping groove 104.

[0072] Further, referring to Fig. 5, the bottom of the card block 11 is integrally formed with a baffle 13 in the vertical direction, when the card block 11 is clamped into the second card slot 104, the baffle 13 abuts to the outer wall of the second card slot 104, and the card block 11 is limited by the baffle 13. At the same time, when it is needed to take out the card block 11 from the second card slot 104, the baffle 13 is waved away from the second card slot 104, and the card block 11 can be taken out from the second card slot 104, which is very convenient.

[0073] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: all equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
