Abstract
Description
Technical Field
[0001] This application relates to the field of wheel rim lubrication technology, and in particular to a solid wheel rim lubrication block with a mortise and tenon structure. Background Technology
[0002] With the increasing speed of railway transportation, traditional grease lubrication methods have gradually revealed their limitations, such as easy lubricant loss and environmental pollution. In contrast, solid dry lubrication technology, by fixing the lubricating material to the wheel rim to form a stable lubricating film, effectively reduces friction and wear between the wheel and rail, thereby extending the service life of the wheels and rails.
[0003] In curved sections or complex road conditions, multiple solid wheel rim lubricating blocks need to be assembled together to improve lubrication efficiency. However, existing solid wheel rim lubricating blocks are typically assembled using adhesive or bolts, which can lead to insecure fixing, causing the blocks to detach during use, and also presents challenges in assembly and maintenance. Therefore, to improve the stability of the wheel rim lubrication process and the ease of assembly of solid wheel rim lubricating blocks, this application proposes a solid wheel rim lubricating block with a mortise and tenon structure. Utility Model Content
[0004] This application provides a solid wheel rim lubricating block with a mortise and tenon structure to solve the technical problems described in the background art above.
[0005] To solve the above-mentioned technical problems, this application adopts the following technical solution:
[0006] This application provides a solid wheel rim lubrication block with a mortise and tenon structure for lubricating wheel rims, comprising:
[0007] The lubricating block body has a first preset length, and a groove of preset depth is provided at one end along its own length direction;
[0008] The tenon has a second preset length and is located at the other end of the length direction of the lubricating block body, and its width is less than the width of the lubricating block body and is adapted to the mortise, wherein the second preset length is less than or equal to the preset depth;
[0009] The tenon on one of the lubricating block bodies is used to insert into the mortise on the other lubricating block body to achieve the connection of the two lubricating block bodies.
[0010] Optionally, the tenon is provided with a limiting plate along its length, and the mortise is provided with a limiting groove that matches the limiting plate.
[0011] Optionally, there are multiple limiting plates, which are equally spaced around the outer peripheral wall of the tenon and all extend along the length direction of the tenon.
[0012] There are multiple limiting grooves, and each of the multiple limiting grooves corresponds to a multiple of the limiting plates.
[0013] Optionally, all four corners of the end of the lubricating block body where the tenon is located are chamfered.
[0014] Optionally, the first preset length is 2.8 to 3.5 times the second preset length.
[0015] Optionally, the width of the tenon gradually decreases from the end where it connects to the lubricating block body to the end away from the lubricating block body.
[0016] Optionally, the lubricating block body and the tenon are integrally formed;
[0017] Both the lubricating block body and the tenon are made of solid lubricant material.
[0018] The solid wheel rim lubricating block with a mortise and tenon structure provided in this application has a mortise groove at one end of a lubricating block body with a first preset length, and a tenon of a second preset length at the other end of the lubricating block body opposite the mortise groove. The connection between the two lubricating block bodies is achieved by inserting the tenon on one lubricating block body into the mortise groove on the other lubricating block body. Since the second preset length is less than or equal to the preset depth, the tenon on one lubricating block body can be fully inserted into the mortise groove of the matching lubricating block body, resulting in higher stability of the connection between the two lubricating block bodies. Compared with existing lubricating block bodies connected by adhesion or bolts, this connection method simplifies the assembly process of multiple lubricating block bodies, thereby improving the convenience of assembling multiple lubricating block bodies. Furthermore, the interlocking of the tenon and mortise between the two lubricating block bodies makes the connection tighter, thus improving the stability of the wheel rim lubrication process and increasing the efficiency of wheel rim lubrication when multiple lubricating block bodies connected by tenons and mortises are used in the wheel rim lubrication system of industrial machinery.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.
[0026] refer to Figures 1 to 4 This application provides a solid wheel rim lubrication block with a mortise and tenon structure for use in the wheel rim lubrication system of industrial machinery to achieve lubrication of the wheel rim, comprising:
[0027] The lubrication block body 100 has a first preset length, and a mortise 101 of preset depth is formed at one end along its length direction. The first preset length can be set according to the size of the wheel rim in the wheel rim lubrication system of the industrial machinery to be lubricated, and this application does not specifically limit it. Furthermore, the preset depth and the size of the mortise 101 can also be set according to actual conditions, and this application does not specifically limit them. The industrial machinery can be subways, high-speed trains, etc., and this application does not specifically limit them. In other words, the solid wheel rim lubricating block with mortise and tenon structure in this application is mainly used for lubricating the wheel rims and tracks of subways, high-speed trains, etc., in industrial machinery.
[0028] The tenon 200 has a second preset length and is located at the other end of the length direction of the lubricating block body 100. Its width is less than the width of the lubricating block body 100 and it is adapted to the mortise 101. The second preset length is less than or equal to the preset depth. The second preset length can be set according to the actual situation, but this application does not specifically limit it.
[0029] In this design, a tenon 200 on one lubricating block body 100 is inserted into a mortise 101 on another lubricating block body 100 to connect the two lubricating block bodies 100. Since the second preset length is less than or equal to the preset depth, this ensures that the tenon 200 of one lubricating block body 100 can be fully inserted into the mortise 101 of the other lubricating block body 100, thereby ensuring the tightness and stability of the connection between the two lubricating block bodies 100.
[0030] The solid rim lubricating block with mortise and tenon structure provided in this application connects two lubricating block bodies 100 by opening a mortise 101 at one end of the lubricating block body 100 with a first preset length and setting a tenon 200 of a second preset length at the other end of the lubricating block body 100 relative to the mortise 101. The tenon 200 on one lubricating block body 100 is inserted into the mortise 101 on the other lubricating block body 100, thereby achieving the connection of the two lubricating block bodies 100. Since the second preset length is less than or equal to the preset depth, the tenon 200 on one lubricating block body 100 can be fully inserted into the mortise 101 of the other lubricating block body 100 that is compatible with it, which makes the connection between the two lubricating block bodies 100 more stable. Compared with the existing connection methods of lubricating block bodies 100 by adhesion or bolts, this connection method simplifies the assembly process of multiple lubricating block bodies 100, thereby improving the convenience of assembling multiple lubricating block bodies 100. In addition, the two lubrication block bodies 100 are connected more tightly by the interlocking of the tenon 200 and the mortise 101, which makes the multiple lubrication block bodies 100 connected by the tenon 200 and the mortise 101 more stable in the wheel flange lubrication system of industrial machinery and make the wheel flange lubrication more efficient.
[0031] During the assembly of multiple lubricating block bodies 100, taking two lubricating block bodies 100 as an example, they are referred to as the first lubricating block body and the second lubricating block body respectively. The tenon of the first lubricating block body is inserted into the mortise of the second lubricating block body, thereby realizing the assembly of the first lubricating block body and the second lubricating block body (two lubricating block bodies 100). When more lubricating block bodies 100 need to be assembled, the above assembly method can be applied in the same way.
[0032] In some embodiments, reference Figure 3 and Figure 4 In this application, the tenon 200 is provided with a limiting plate 201 along its length direction, and the mortise 101 is provided with a limiting groove 1011 that is adapted to the limiting plate 201.
[0033] In the above embodiment, when the tenon 200 of one lubricating block body 100 is inserted into the mortise 101 of another lubricating block body 100, the limiting plate 201 on the tenon 200 of one lubricating block body 100 is also inserted into the limiting groove 1011 in the mortise 101 of the other lubricating block body 100, thereby achieving the limiting of the connection between the tenon 200 and the mortise 101, thereby improving the tightness and stability of the connection between the two lubricating block bodies 100.
[0034] In some embodiments, reference Figure 3 and Figure 4 In this application, there are multiple limiting plates 201. The multiple limiting plates 201 are equally spaced around the outer peripheral wall of the tenon 200 and all extend along the length direction of the tenon 200. This ensures the uniformity of the multiple limiting plates 201 set on the tenon 200. The number of limiting plates 201 can be set according to actual needs, and this application does not make a specific limitation on it.
[0035] In addition, there are multiple limit slots 1011, and each of the multiple limit slots 1011 corresponds to a multiple limit plate 201.
[0036] In the above embodiments, when the tenon 200 on one lubrication block body 100 is inserted into the mortise 101 on another lubrication block body 100, the multiple limiting plates 201 evenly distributed on the tenon 200 are also inserted into the multiple limiting grooves 1011 evenly distributed in the mortise 101, making the connection between the tenon 200 and the mortise 101 more stable, and further improving the stability of the lubrication block body 100 in the wheel rim lubrication system of industrial machinery.
[0037] In some embodiments, reference Figure 1 and Figure 4 In this application, the four corners of the end of the lubricating block body 100 with the tenon 200 are all chamfered. This facilitates the connection between the end of the lubricating block body 100 with the tenon 200 and the end of the lubricating block body 100 with the mortise 101, improving assembly efficiency. Furthermore, the chamfering also prevents friction between the two connected lubricating block bodies 100, thus protecting the lubricating block body 100.
[0038] In some embodiments, the first preset length in this application is 2.8 to 3.5 times the second preset length. Since the lubricating block body 100 needs to have both a mortise 101 and a tenon 200, and the tenon 200 of one lubricating block body 100 is used to insert into the mortise 101 of another lubricating block body 100, in order to ensure that the tenon 200 can fully enter the mortise 101 so that the two lubricating block bodies 100 are connected more tightly, and that the opening of the mortise 101 does not affect the strength of the lubricating block body 100, the length of the lubricating block body 100 (i.e., the first preset length) needs to be in a certain proportion to the length of the tenon 200 (the second preset length). When the first preset length is 2.8 to 3.5 times the second preset length, not only can the tightness of the connection between the two lubricating block bodies 100 and the strength of the lubricating block body 100 be ensured, but the material used to manufacture the lubricating block body 100 can also be saved. The multiples of the first preset length and the second preset length can be set according to actual needs, and this application does not impose specific limitations on them.
[0039] In some embodiments, reference Figure 1 , Figure 3 and Figure 4 In this application, the width of the tenon 200 gradually decreases from the end connected to the lubricating block body 100 towards the end away from the lubricating block body 100. Since the mortise 101 is adapted to the tenon 200, meaning the width of the mortise 101 gradually decreases from the outside in, during the assembly of the two lubricating block bodies 100, the end of the tenon 200 away from the lubricating block body 100 enters the mortise 101 first. Since the width of the tenon 200 gradually decreases from the end connected to the lubricating block body 100 towards the end away from the lubricating block body 100, this allows the smaller end of the tenon 200 to enter the larger end of the mortise 101 first and gradually extend into the mortise 101. This makes the assembly of the tenon 200 and the mortise 101 easier, thereby improving the stability of the assembly process of the two lubricating block bodies 100.
[0040] In some embodiments, the lubricating block body 100 and the tenon 200 in this application are integrally formed; wherein, the lubricating block body 100 and the tenon 200 can be integrally formed by a mold, and the overall stability of the integrally formed lubricating block body 100 and the tenon 200 is higher.
[0041] In addition, both the lubricating block body 100 and the tenon 200 are made of solid lubricant. Commonly used solid lubricants include molybdenum disulfide (MoS2), colloidal graphite, graphite, polytetrafluoroethylene (PTFE), paraffin wax, and stearic acid. Among these, graphite, MoS2, and PTFE are high-temperature lubricants, frequently used and widely applied solid lubricants. Due to their excellent thermal stability, these three solid lubricants maintain good lubrication performance even when the wheel rim and rail experience high-speed friction and increased temperature in the wheel flange lubrication system of industrial machinery, exhibiting low friction coefficients and strong compressive strength. Furthermore, solid lubricant is the primary lubricating material during the integral molding of the lubricating block body 100 and the tenon 200. An adhesive is also needed to press these materials together before use, and nitrile rubber is commonly used as the adhesive.
[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
