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.

[0023] At present, bearing boxes are usually made of strong and durable materials such as cast iron, steel plate, and cast steel to withstand the various forces and vibrations generated when mechanical equipment is running. Generally speaking, a large number of bearing boxes are installed on a large mechanical equipment. Using the above materials to make bearing boxes will greatly increase the cost of the mechanical equipment. If cheaper bearing boxes can be used, the cost of mechanical equipment can be greatly reduced. However, if other cheaper materials other than the above are used to make bearing boxes, the bearing box strength will be insufficient, resulting in damage.

[0024] Based on this, the inventor provides a bearing box, which uses cheaper materials to make the box body and sets reinforcing plates on opposite sides of the box body to ensure that the bearing box has sufficient strength. This can not only reduce the cost of the entire bearing box, but also achieve sufficient structural strength.

[0025] The following is combined with Figures 1 to 9 The bearing box 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 box 10, which can be used to install a bearing.

[0026] Please also see Figure 1-Figure 4 In this embodiment, the bearing box 10 may include a box body 110, a first reinforcing plate 120 and a second reinforcing plate 130. The box body 110 may be made of nylon material, and the first reinforcing plate 120 and the second reinforcing plate 130 may be made of rigid material, such as cast iron, steel plate, cast steel and other strong and durable materials. The first reinforcing plate 120 and the second reinforcing plate 130 may be respectively arranged at opposite ends of the box body 110 to improve the structural strength of the entire bearing box 10.

[0027] Specifically, the box body 110 has a first end face 111 and a second end face 112 that are connected, that is, the interior of the box body 110 is a hollow structure, and is formed with an installation space 115 for installing the bearing. The first reinforcing plate 120 can be arranged on the first end face 111, and the second reinforcing plate 130 can be arranged on the second end face 112. In this embodiment, in order to ensure that the bearing box 10 as a whole has sufficient structural strength, the first reinforcing plate 120, the box body 110 and the second reinforcing plate 130 can be fastened and connected by bolts 2. It should be noted that, since the nylon material has a certain elasticity, the first reinforcing plate 120, the box body 110 and the second reinforcing plate 130 can be tightened together by bolts 2, so that the box body 110 produces a certain elastic deformation, thereby improving the structural strength of the entire bearing box 10. In addition, since the box body 110 will undergo adaptive elastic deformation during the installation process with the first reinforcing plate 120 and during the installation process with the second reinforcing plate 130, the processing accuracy of the box body 110 will be greatly reduced in the embodiment of the present application, and the assembly accuracy during the assembly process of the box body 110, the first reinforcing plate 120 and the second reinforcing plate 130 will also be greatly reduced, which is beneficial to ensure sufficient strength of the box body 110, reduce the production cost when producing the box body 110, and ultimately reduce the production cost of the entire bearing box 10.

[0028] The first end surface 111 may be provided with a mounting port 111a, and the second end surface 112 may be provided with an insertion port 112a. The mounting port 111a may be used for bearing installation, and the insertion port 112a may be used for rod installation connected to the bearing. In this embodiment, the aperture of the insertion port 112a is larger than the aperture of the mounting port 111a. The box body 110 has a mounting seat 113 inside, and the mounting seat 113 is located at the junction of the insertion port 112a and the mounting port 111a. Since the insertion port 112a and the mounting port 111a have an aperture difference, the mounting seat 113 is a stepped structure, and the mounting seat 113 can be used to install the bearing.

[0029] For further information, please also refer to Figure 4 and Figure 5 In this embodiment, the bearing box 10 may further include a second limit member 170, and a limit groove 114 is further provided inside the box body 110. The second limit member 170 may be arranged in the limit groove 114. When the bearing is installed on the mounting seat 113, the bearing may abut between the second limit member 170 and the mounting seat 113.

[0030] It should be noted that the embodiment of the present application does not limit the specific structure of the second limit member 170 and the limit groove 114. For example, in one embodiment, the limit groove 114 can be arranged in the radial direction of the same cross-section of the installation space 115, and a plurality of limit grooves 114 can be arranged at intervals. The number of the second limit members 170 can match the number of the limit grooves 114. In this embodiment, the second limit member 170 can be a block structure.

[0031] For example, in another embodiment, the limit groove 114 can be opened in a radial direction of the installation space 115. In this embodiment, the limit groove 114 is an integral through groove, and in this embodiment, the second limit member 170 can be set to an annular structure, or an annular structure with a notch, etc., which can be specifically set according to actual conditions and is not limited here.

[0032] It should be noted that the embodiment of the present application does not limit the connection method between the limiting groove 114 and the second limiting member 170, for example, it can be a snap connection, an interference connection, or a mortise and tenon connection, etc. The specific configuration can be made according to the actual situation.

[0033] In this embodiment, the axial direction of the installation space 115 can be the same as the axial direction of the bearing, so that the bearing can be easily installed on the mounting seat 113. Considering that the bearing located in the bearing box 10 needs to be regularly oiled and changed, in this embodiment, the first reinforcing plate 120 can also have an oil filling hole 122 that is set through, and the oil filling hole 122 can be connected to the installation space 115, so that the user can easily fill the installation space 115 with oil through the oil filling hole 122. In addition, in this embodiment, the bearing box 10 can also include an oil filling plug 150, and the oil filling plug 150 is detachably arranged in the oil filling hole 122. It should be noted that the embodiment of the present application also does not limit the connection method between the oil filling plug 150 and the oil filling hole 122, for example, it can be a threaded connection, and for example, it can be an interference connection, etc., which can be set according to actual conditions.

[0034] In addition, in this embodiment, there is a gap 116 between the surface of the limiting groove 114 close to the first end face 111 and the edge of the installation space 115 close to the first end face 111. The gap 116 can be used to load lubricating oil. When the user fills oil into the installation space 115 through the oil filling hole 122, the lubricating oil will first be filled in the aforementioned gap 116, and then gradually filled into the entire installation space 115, so that the original lubricating oil in the installation space 115 can be replaced with the newly injected lubricating oil.

[0035] For further information, please also refer to Figure 3 and Figure 6 In one embodiment, the bearing box 10 may further include a first sealing ring 140. The first sealing ring 140 may be disposed between the first reinforcing plate 120 and the first end face 111. The first sealing ring 140 may be used to seal the gap between the first reinforcing plate 120 and the first end face 111. It can be understood that when the bearing rotates in the bearing box 10, oil is usually injected into the bearing box 10 to ensure that the bearing rotates more smoothly. Therefore, the setting of the first sealing ring 140 can effectively prevent the aforementioned lubricating oil from flowing out of the aforementioned gap.

[0036] It should be noted that the embodiment of the present application does not limit the specific setting method of the first sealing ring 140. For example, in one embodiment, the first sealing ring 140 can be a diaphragm-like structure and cover the first end surface 111. The first reinforcing plate 120 then squeezes the first sealing ring 140 to achieve a sealing effect between the first reinforcing plate 120 and the box body 110.

[0037] For another example, in this embodiment, at least one of the first end surface 111 and the first reinforcing plate 120 is provided with a first mounting groove 121 matched with the first sealing ring 140, and the first sealing ring 140 can be embedded in the first mounting groove 121. In this embodiment, the first sealing ring 140 can be configured to be made of an elastic material, such as rubber, resin, etc. The aforementioned material can not only play a sealing role, but also has good corrosion resistance, which is conducive to improving the service life of the bearing box 10.

[0038] For further information, see Figure 4 In this embodiment, the depth of the first mounting groove 121 can be less than the thickness of the first sealing ring 140, and the first sealing ring 140 can be interference-connected with the first mounting groove 121, which can further improve the sealing effect. In addition, the width of the first mounting groove 121 can be set to be greater than the width of the first sealing ring 140, which can also reduce the assembly accuracy between the first sealing ring 140 and the first mounting groove 121, and can also reduce the production cost of the entire bearing box 10.

[0039] Please refer again Figure 3 It can be understood that the bearing box 10 provided in the embodiment of the present application can also include a second sealing ring 160, which can be arranged between the second reinforcing plate 130 and the second end surface 112, and at least one of the second end surface 112 and the second reinforcing plate 130 can be provided with a second mounting groove 132 matched with the second sealing ring 160, and the second sealing ring 160 can be embedded in the second mounting groove 132. That is, in one embodiment, the matching method of the second sealing ring 160 and the second mounting groove 132 can refer to the matching method of the first sealing ring 140 and the first mounting groove 121, which will not be described in detail here.

[0040] Please also see Figure 4 , Figure 5 and Figure 7 In the present embodiment, the second sealing ring 160 and the second mounting groove 132 may also adopt another matching method. Specifically, in this matching method, the second mounting groove 132 may be arranged on the second end surface 112, and the second mounting groove 132 may be connected to the insertion port 112a, and the second mounting groove 132 may be arranged on the periphery of the insertion port 112a. That is to say, in this embodiment, the second mounting groove 132 may not need to be opened separately. The second mounting groove 132 and the insertion hole 131 are connected to avoid grooving in other areas of the second end surface 112, which is beneficial to improve the structural strength of the entire box body 110.

[0041] For further information, see Figure 8 and Fig. 9In this embodiment, the second sealing ring 160 may include a first structural member 161 and a second structural member 162, wherein the first structural member 161 can be embedded in the insertion port 112a, and the second structural member 162 can be embedded in the second installation groove 132, which can facilitate the stability of the connection between the second sealing ring 160 and the box body 110.

[0042] In addition, in one embodiment, a first limiting member 132a may be provided in the second installation groove 132, and the second sealing ring 160 may be made of elastic material. The first limiting member 132a may be used to abut the second sealing ring 160 and make the second sealing ring 160 and the second installation groove 132 have an interference fit.

[0043] The embodiment of the present application does not limit the specific setting method of the first limit member 132a. For example, in one embodiment, the first limit member 132a can be set in the second installation groove 132 and occupy the depth space of the second installation groove 132. Then, when the second sealing ring 160 is installed in the second installation groove 132, the first limit member 132a can be against the second sealing ring 160 in the axial direction of the installation space 115, thereby achieving the effect of interference connection.

[0044] For another example, in this embodiment, the first stopper 132a can also be arranged in the second installation groove 132 and occupy the width space of the second installation groove 132, and then when the second sealing member is installed in the second installation groove 132, the first stopper 132a can abut against the second sealing ring 160 in the radial direction of the installation space 115, thereby achieving the effect of interference connection. Which setting method is adopted can be set according to actual conditions and is not limited here.

[0045] For further information, please also refer to Figure 3 and Figure 4 , a part of the second structural member 162 is connected to the first structural member 161, so that there is a gap at the connection between the first structural member 161 and the second structural member 162. When the user injects oil into the installation space 115 through the oil injection hole 122, the second sealing ring 160 will be elastically deformed, thereby exposing the aforementioned gap, and the used lubricating oil can be discharged from the installation space 115 through the aforementioned gap, thereby replacing the lubricating oil in the bearing box 10. When the user stops injecting oil, the second sealing ring 160 resumes its elastic deformation, and the aforementioned gap will be sealed, thereby ensuring that the bearing box 10 will not leak oil during normal operation of the bearing.

[0046] Also, see Fig.10The embodiment of the present application further provides a belt filter press 1, which includes the aforementioned bearing box 10. In this embodiment, due to the use of the aforementioned bearing box 10, the manufacturing cost of the belt filter press 1 can be greatly reduced.

[0047] In summary, the bearing box 10 provided in the embodiment of the present application is provided with a first reinforcing plate 120 on the first end face 111 of the box body 110, and a second reinforcing plate 130 on the second end face 112 of the box body 110, and then the first reinforcing plate 120, the box body 110 and the second reinforcing plate 130 are tightened with bolts 2, so that the entire bearing box 10 has sufficient structural strength, wherein the box body 110 is made of nylon material, and the first reinforcing plate 120 and the second reinforcing plate 130 are made of rigid material. Compared with the traditional bearing box 10 which is supported by rigid materials, the bearing box 10 provided in the embodiment of the present application has low production cost and sufficient structural strength. Applying the above-mentioned bearing box 10 to the belt filter press 1 can greatly reduce the production cost of the entire belt filter press 1.

[0048] 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.

[0049] 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. For example, the described methods may be performed in an order different from that described, and various steps may be added, omitted, or combined.
