Description

Technical Field

[0001] This utility model relates to the field of sliding bearing structure technology, and in particular to a sliding bearing structure for aero-engines that is easy to clean. Background Technology

[0002] The internal structure of an aero-engine is intricate, and the transmission between these structures requires the assistance of structures such as bearings and shafts. Sliding bearings are one of the commonly used transmission components in aero-engines.

[0003] In practical applications, the existing sliding bearing structure has relatively complete functions and structure, which can meet the needs of daily use. However, the following problems still exist:

[0004] During use, dust can easily accumulate between the bearing body and the bearing housing, and dust can also easily adhere to the bearing body and the shaft, thus affecting the normal use of the bearing body. At this time, the bearing needs to be cleaned and maintained. However, frequent disassembly and maintenance will increase the overall cost of use and is very inconvenient.

[0005] Therefore, this utility model provides a sliding bearing structure for aircraft engines that is easy to clean. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and provide an easy-to-clean sliding bearing structure for aero-engines.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an easy-to-clean sliding bearing structure for an aircraft engine, comprising a bearing housing, a bearing body installed on the inner wall of the bearing housing, and a shaft installed on the inner ring of the bearing body; protective cleaning structures are provided on both sides of the bearing housing; a heat dissipation cleaning structure is provided on one side of the protective cleaning structure; the protective cleaning structure includes two first annular guard frames and a second annular guard frame, a connecting ring block is fixedly connected to one side of the first annular guard frame, a locking ring groove is opened on one side of the connecting ring block, a locking ring block is locked into the inner wall of the locking ring groove, and an annular brush plate is fixedly connected to one side of the outer surface of the locking ring block; the heat dissipation cleaning structure includes a heat dissipation mesh plate, and the heat dissipation mesh plate is fixedly connected to one side of the second annular guard frame.

[0008] In a preferred embodiment, the bearing housing has symmetrically formed annular grooves on both sides. Annular blocks are engaged with the inner walls of both annular grooves. One side of one annular block is fixedly connected to a first annular protective frame, and one side of the other annular block is fixedly connected to a second annular protective frame. The shaft is inserted into the inner wall of the first annular protective frame. A first insertion hole is formed in the inner wall of the annular groove, and a second insertion hole is formed in the inner wall of both annular blocks. Threaded rods are inserted into the inner walls of the first and second insertion holes. A fixing nut is fixedly connected to one end of the threaded rod. A first threaded hole is formed in the inner wall of the locking annular groove, and a second threaded hole is formed in the inner wall of the locking annular block. Threaded rods are threadedly connected to the inner walls of the first and second threaded holes.

[0009] The technical effect of adopting the above-mentioned further solution is that, under the action of the positioning ring block and the positioning ring groove, the annular brush plate can be fixed, and then the positioning ring block and the positioning ring groove can be firmly fixed by the threaded rod in conjunction with the first screw hole and the second screw hole. At the same time, under the action of the annular locking block and the annular locking groove, the first annular guard frame and the second annular guard frame can be fixed, and then the bearing body and the bearing seat can be fixed, while the bearing body and the shaft can be cleaned and protected.

[0010] In a preferred embodiment, a rotating block is rotatably connected to the inner wall of the heat dissipation mesh plate, a connecting auxiliary rod is fixedly connected to one side of the rotating block, and a cleaning brush plate is fixedly connected to one end of the connecting auxiliary rod.

[0011] The technical effect of adopting the above-mentioned further solution is that, under the action of the rotating block, the cleaning brush plate can be rotated, thereby assisting in cleaning the dust adhering to the outer surface of the heat dissipation mesh plate.

[0012] In a preferred embodiment, a circular frame is fixedly connected to the other end of the rotating block, and a rubber protrusion is fixedly connected to the inner wall of the circular frame.

[0013] The technical effect of adopting the above-mentioned further solution is that, under the action of the circular clamping frame, one end of the connection between the shaft and the bearing body can be fixed to the circular clamping frame, and then the circular clamping frame can drive the rotating block to rotate under the drive of the shaft, providing driving force.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] By setting up a protective cleaning structure, the bearing housing and bearing body can be protected by the first and second annular protective frames. At the same time, the connection between the bearing body and the shaft can be protected and cleaned by the annular brush plate. This makes it difficult for dust to enter the interior of the bearing body and bearing housing, thus eliminating the need for frequent disassembly and maintenance and reducing the overall operating cost. By setting up a heat dissipation cleaning structure, the bearing housing and bearing body can be assisted in heat dissipation by the heat dissipation mesh plate. At the same time, the dust adhering to the heat dissipation mesh plate can be assisted in cleaning by the cleaning brush plate. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-5 As shown, this embodiment provides a technical solution: an easy-to-clean sliding bearing structure for an aircraft engine, including a bearing housing 1, a bearing body 2 installed on the inner wall of the bearing housing 1, and a shaft 3 installed on the inner ring of the bearing body 2; protective cleaning structures 4 are provided on both sides of the bearing housing 1; a heat dissipation cleaning structure 5 is provided on one side of the protective cleaning structure 4; the protective cleaning structure 4 includes two first annular guard frames 44 and a second annular guard frame 45, a connecting ring block 49 is fixedly connected to one side of the first annular guard frame 44, a locking ring groove 410 is opened on one side of the connecting ring block 49, a locking ring block 411 is locked into the inner wall of the locking ring groove 410, and an annular brush plate 415 is fixedly connected to one side of the outer surface of the locking ring block 411; the heat dissipation cleaning structure 5 includes a heat dissipation mesh plate 5. 1. The heat dissipation mesh plate 51 is fixedly connected to one side of the second annular guard frame 45. By setting the protective cleaning structure 4, under the action of the first annular guard frame 44 and the second annular guard frame 45, the bearing seat 1 and the bearing body 2 can be protected. At the same time, under the action of the annular brush plate 415, the connection between the bearing body 2 and the shaft 3 can be protected and cleaned. This makes it difficult for dust to enter the interior of the bearing body 2 and the bearing seat 1, thus eliminating the need for frequent disassembly and maintenance, and reducing the overall operating cost. By setting the heat dissipation cleaning structure 5, under the action of the heat dissipation mesh plate 51, the bearing seat 1 and the bearing body 2 can be assisted in heat dissipation. At the same time, under the action of the cleaning brush plate 54, the dust adhering to the heat dissipation mesh plate 51 can be assisted in cleaning.

[0027] Going further, such as Figures 3-4As shown: Symmetrical annular grooves 41 are provided on both sides of the bearing housing 1. Annular blocks 43 are engaged with the inner walls of both annular grooves 41. One side of one annular block 43 is fixedly connected to the first annular protective frame 44, and one side of the other annular block 43 is fixedly connected to the second annular protective frame 45. The shaft 3 is inserted into the inner wall of the first annular protective frame 44. A first insertion hole 42 is provided on the inner wall of the annular groove 41. A second insertion hole 46 is provided on the inner wall of both annular blocks 43. Threaded rods 47 are inserted into the inner walls of the first insertion hole 42 and the second insertion hole 46. A fixing nut 48 is fixedly connected to one end of the threaded rod 47. A first threaded hole 412 is provided on the inner wall of the locking annular groove 410. The inner wall of the locking ring block 411 is provided with a second screw hole 413. The inner walls of the first screw hole 412 and the second screw hole 413 are threadedly connected to a threaded locking rod 414. Under the action of the locking ring block 411 and the locking ring groove 410, the annular brush plate 415 can be fixed. Then, the threaded locking rod 414, together with the first screw hole 412 and the second screw hole 413, can firmly fix the locking ring block 411 and the locking ring groove 410. At the same time, under the action of the annular locking block 43 and the annular locking groove 41, the first annular guard frame 44 and the second annular guard frame 45 can be fixed. Then, the bearing body 2 and the bearing seat 1 can be fixed, and the bearing body 2 and the shaft 3 can be cleaned and protected.

[0028] The above solutions also have the problem that the heat dissipation mesh 51 easily accumulates dust, resulting in poor heat dissipation. Figure 4 and Figure 5 As shown: In this solution, a rotating block 52 is rotatably connected to the inner wall of the heat dissipation mesh plate 51. A connecting auxiliary rod 53 is fixedly connected to one side of the rotating block 52. A cleaning brush plate 54 is fixedly connected to one end of the connecting auxiliary rod 53. Under the action of the rotating block 52, the cleaning brush plate 54 can be rotated, thereby assisting in cleaning the dust adhering to the outer surface of the heat dissipation mesh plate 51.

[0029] The above solutions also suffer from the problem of manually rotating the cleaning brush plate 54 being time-consuming and laborious, such as... Figure 4 and Figure 5 As shown, a circular frame 55 is fixedly connected to the other end of the rotating block 52. A rubber protrusion 56 is fixedly connected to the inner wall of the circular frame 55. Under the action of the circular frame 55, one end of the connection between the shaft 3 and the bearing body 2 can be fixed to the circular frame 55. Thus, under the drive of the shaft 3, the circular frame 55 can drive the rotating block 52 to rotate, providing driving force.

[0030] Working principle:

[0031] like Figure 1-5 As shown:

[0032] In use: the annular locking block 43 is inserted into the inner wall of the annular locking groove 41, and then the threaded rod 47 is inserted into the inner wall of the first insertion hole 42 and the second insertion hole 46, so that the fixing nut 48 is fixed with the threaded rod 47. At this time, the first annular guard frame 44 and the second annular guard frame 45 can be fixed.

[0033] At this time, the locking ring block 411 is fixed to the locking ring groove 410, and then the threaded locking rod 414 is fixed to the first screw hole 412 and the second screw hole 413, thereby fixing the annular brush plate 415.

[0034] When the shaft 3 is inserted into the inner wall of the circular frame 55, the shaft 3 can drive the circular frame 55 to rotate, which in turn can drive the cleaning brush plate 54 to rotate, thereby assisting in cleaning the heat dissipation mesh plate 51.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
