[0002] The bearing box is a fixed part installed on mechanical equipment. It is mainly used to support and fix the bearing to ensure that the bearing can work properly. After the bearing has worked for a long time, dust will combine with the lubricating oil in the bearing box, causing the bearing to rotate less smoothly, thereby reducing the mechanical efficiency. Therefore, it is necessary to regularly fill the bearing box with oil to replace the lubricating oil in the bearing box to ensure that the mechanical efficiency will not be reduced.

[0003] However, in the prior art, the oil filling port of the standard bearing box is usually arranged above the standard bearing box.

DETAILED DESCRIPTION

[0020] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. 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 implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0021] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0022] The inventive concept of the present application is described here: The bearing box is a fixed part installed on mechanical equipment. It is mainly used to support and fix the bearing to ensure that the bearing can work properly. After the bearing has worked for a long time, dust will combine with the lubricating oil in the bearing box, causing the bearing to rotate less smoothly, thereby reducing the mechanical efficiency. Therefore, it is necessary to regularly fill the bearing box with oil to replace the lubricating oil in the bearing box to ensure that the mechanical efficiency will not be reduced.

[0023] However, in the prior art, the oil filling port of the standard bearing box is usually arranged above the standard bearing box. In some equipment with narrow height space, such as a belt filter press, it is difficult for users to fill oil from above the standard bearing box.

[0024] Specifically, the oil filling process of users is usually to pour lubricating oil into the standard bearing box from the oil filling port set above the standard bearing box for oil filling. However, in the belt filter press, the space above the standard bearing box is limited. Even if the user uses an oil filling tool, it is difficult to quickly perform the oil filling operation. In addition, in a belt filter press, the number of standard bearing boxes is very large. If the traditional oil filling method is used, it will be very time-consuming and laborious.

[0025] Therefore, the user either needs to disassemble the entire device or customize a special non-standard bearing box to more conveniently perform oiling. However, the process of disassembling the entire device is very cumbersome, which makes the oiling process very complicated, and customizing a special non-standard bearing box will increase costs.

[0026] Based on this, the inventor provides a bearing installation assembly, which improves on the basis of a standard bearing box so that users can inject oil from the side. This can greatly improve the user's oiling efficiency and eliminates the need to customize a special non-standard bearing box, thereby reducing costs.

[0027] The following is combined with Figures 1 to 9 The bearing installation assembly 10 provided by the present application is described in detail through specific embodiments and application scenarios. The embodiment of the present application provides a bearing installation assembly 10, which can be used in equipment with a small height space and can facilitate users to fill oil into the bearing installation assembly 10.

[0028] Please also see Figure 1-Figure 4 In this embodiment, the bearing installation assembly 10 may include: a box body 110, a first sealing member 120 and a sealing plug 130. Figure 4 The box body 110 may have a first end face 111 and a second end face 112 that are connected. Specifically, the first end face 111 and the second end face 112 are two end faces along the axial direction of the box body 110. An installation space 113 for installing the bearing 2 is formed inside the box body 110. The embodiment of the present application does not limit the specific structure of the box body 110. For example, in one embodiment, the box body 110 may adopt a standard bearing box as the box body 110. In another embodiment, any other form of the box body 110 may also be adopted without limitation.

[0029] The first seal 120 may be connected to one end of the box body 110 and used to seal the first end surface 111. The first seal 120 is provided with an oil filling hole 121. The oil filling hole 121 may be connected to the installation space 113. The user may fill the installation space 113 with oil through the oil filling hole 121. In this embodiment, since the first seal 120 is located on the end surface of the box body 110, the user may fill the installation space 113 with oil from the side of the box body 110 without filling the installation space 113 with oil from the top surface of the box body 110. When the bearing mounting assembly 10 is installed in an area with a narrow height space, it is convenient for the user to perform the oil filling operation in the installation space 113.

[0030] It should be noted that the embodiment of the present application does not limit the connection method between the first sealing member 120 and the box body 110, nor does it limit the specific structure of the first sealing member 120. For example, in one embodiment, the first sealing member 120 can be directly attached to the first end surface 111 of the box body 110. For example, in another embodiment, the first sealing member 120 can be connected to the box body 110 by a snap connection or an interference connection. For details, please also refer to Figure 3 and Figure 4 In this embodiment, the inner wall of the box body 110 can be provided with a first installation groove 114, and the first installation groove 114 can be arranged on one side of the installation space 113 close to the first end surface 111, so as to increase the installation space 113 and avoid occupying too much installation space 113 when installing the first sealing member 120.

[0031] For further information, please also refer to Figure 3 and Figure 5 In this embodiment, the first sealing member 120 may be made of an elastic material, such as rubber or resin, which may have a certain elastic deformation. The first sealing member 120 may include an embedding portion 122 and a sealing portion 123. The embedding portion 122 may be embedded in the first mounting groove 114, and the oil injection hole 121 may be provided in the sealing portion 123. The embedding portion 122 may be provided with a deformation notch 122a, which may be used to provide a deformation space for the first sealing member 120.

[0032] Specifically, when the user fills the installation space 113 with oil, due to the existence of the deformation notch 122a, when the installation space 113 is filled with the lubricating oil, the first seal 120 can continue to be squeezed. At this time, the embedded portion 122 can be squeezed into the deformation notch 122a, so that the first seal 120 as a whole produces elastic deformation. This can not only be used to remind the user that the installation space 113 is already filled with lubricating oil, but also make the lubricating oil in the installation space 113 filled more fully.

[0033] Further, please also refer to Figure 3 and Figure 4 In one embodiment, the inner wall of the box body 110 may also be provided with a second mounting groove 115, and the bearing mounting assembly 10 may also include a second sealing member 140 matching the second mounting groove 115. The second sealing member 140 may be connected to the other end of the box body 110 to seal the second end surface 112. Please also refer to Figure 6 and Figure 7 It should be noted that, in this embodiment, the second end face 112 is used to install the connecting rod 3 connected to the bearing 2, so the second seal 140 has a through hole 141 for the connecting rod 3 to pass through, and the through hole 141 is connected to the installation space 113. The through hole 141 can be used for the connecting rod 3 to be inserted into the installation space 113, and the second seal 140 is used to seal the gap 117 between the connecting rod 3 and the installation space 113.

[0034] Similarly, the embodiment of the present application does not limit the connection method between the second sealing member 140 and the box body 110, nor does it limit the specific structure of the second sealing member 140. For example, in one embodiment, the connection method between the second sealing member 140 and the box body 110 can be set with reference to the connection method between the first sealing member 120 and the box body 110, which will not be described in detail here.

[0035] Please refer again Figure 3 and Figure 4 In this embodiment, the second sealing member 140 may also be made of an elastic material, and the second sealing member 140 may also be configured to include: a first structural portion 142 and a second structural portion 143, the first structural portion 142 may be embedded in the second mounting groove 115, the first structural portion 142 may have a connecting groove 142a recessed along the direction of the oil filling hole 121, and a partial area of ​​the second structural portion 143 may be connected to the connecting groove 142a, so that a gap is provided at the connection between the first structural portion 142 and the second structural portion 143, and the gap may be used to realize one-way conduction from the inside of the mounting space 113 to the outside of the mounting space 113.

[0036] Specifically, when the user fills the installation space 113 with oil through the oil filling hole 121, the lubricating oil gradually fills the installation space 113. Since the first seal 120 and the second seal 140 are both made of elastic materials, the first seal 120 and the second seal 140 have the ability to deform. When the second seal 140 is squeezed, the gap between the first structure part 142 and the second structure part 143 will be stretched open, thereby making the inside of the installation space 113 and the outside of the installation space 113 conductive. At this time, since the installation space 113 is already filled with lubricating oil, the lubricating oil in the installation space 113 will flow to the outside of the installation space 113 through the gap, thereby replacing the original lubricating oil in the installation space 113 with the newly injected lubricating oil. When the user stops filling the installation space 113 with oil, the second seal 140 will no longer be squeezed. At this time, the aforementioned gap will return to a sealed state to block the connection between the inside and outside of the installation space 113, thereby preventing the lubricating oil in the installation space 113 from flowing out.

[0037] Please refer again Figure 3 and Figure 4 In one embodiment, the inner wall of the box body 110 may be provided with a bearing groove 116 for installing the bearing 2, and the bearing groove 116 is located in the installation space 113. In this embodiment, the width of the bearing groove 116 may be set to be greater than the width of the bearing 2. It can be understood that the width of the bearing 2 mentioned above refers to the length of the bearing 2 along its axial direction. In this embodiment, the bearing installation assembly 10 may also include a stopper 150, which may be provided in the bearing groove 116. When the bearing 2 is installed in the bearing groove 116, the stopper 150 may abut against the bearing 2 to limit and fix the bearing 2 between the inner wall of the bearing groove 116 and the side wall of the stopper 150.

[0038] It should be noted that the embodiment of the present application does not limit the specific structure of the limit member 150, nor does it limit the specific connection method between the limit member 150 and the bearing groove 116. For example, in one embodiment, the limit member 150 can be embedded in the bearing groove 116 by snap-fitting. For example, in another embodiment, the limit member 150 can also be set in the bearing groove 116 by injection molding. The specific setting can be made according to actual conditions.

[0039] In this embodiment, the stopper 150 can be embedded in the bearing groove 116 by snapping. Specifically, the stopper 150 can be set as an annular structure. Preferably, the stopper 150 can be set as an annular structure with a gap. This can reduce the material used for the stopper 150, thereby reducing the cost and reducing the overall weight of the bearing mounting assembly 10.

[0040] For details, please refer to Figure 8 The limit member 150 may have a first end 151 and a second end 152 relative to each other, and the first end 151 and the second end 152 are arranged relative to each other so that the limit member 150 presents a roughly "C"-shaped structure, and the limit member 150 may be preset with a prestress that makes the first end 151 and the second end 152 move away from each other, that is, the first end 151 and the second end 152 have a tendency to move away from each other, so that when the limit member 150 is installed in the bearing groove 116, an axial force can be generated on the inner surface of the bearing groove 116, thereby preventing the limit member 150 from collapsing and falling into the bearing groove 116.

[0041] Please refer again Figure 3 and Figure 4 In one embodiment, there is a gap 117 between the surface of the bearing groove 116 close to the first end face 111 and the edge of the installation space 113 close to the first end face 111. The gap 117 can be used to load lubricating oil. When the user fills oil into the installation space 113 through the oil filling hole 121, the lubricating oil will first fill the aforementioned gap 117, and then gradually fill the entire installation space 113, so that the original lubricating oil in the installation space 113 can be replaced with the newly injected lubricating oil, thereby ensuring that the original lubricating oil in the bearing 2 is completely replaced.

[0042] Also, see Fig. 9 The embodiment of the present application further provides a belt filter press 1, which includes the aforementioned bearing mounting assembly 10. In this embodiment, due to the use of the aforementioned bearing mounting assembly 10, the manufacturing cost of the belt filter press 1 can be greatly reduced, and it is convenient for the user to inject oil from the side into the installation space 113 of the bearing mounting assembly 10 installed in the belt filter press 1.

[0043] In summary, by adding a first seal 120 and a sealing plug 130 on the basis of the box body 110 (i.e., a standard bearing box), and connecting the first seal 120 to one end of the box body 110, one end of the box body 110 is sealed. An oil filling hole 121 is provided on the first seal 120, and the user can fill oil into the box body 110 through the oil filling hole 121. Compared with the traditional standard bearing box, the bearing installation assembly 10 provided in the embodiment of the present application can be filled with oil from the side, so that when the bearing installation assembly 10 is installed in a highly narrow area, it can also be filled with oil conveniently and quickly. After the user completes the oil filling operation, the sealing plug 130 can be installed in the oil filling hole 121 to achieve sealing. The bearing installation assembly 10 provided in the embodiment of the present application solves the problem that the standard bearing box in the prior art is difficult to fill with oil from the top, while avoiding the customization of a special non-standard bearing box, thereby reducing the cost of mechanical equipment.

[0044] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0045] In addition, it should be noted that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in a reverse order according to the functions involved.
