Description

Technical Field

[0001] This utility model relates to the field of quick-release structure technology, specifically to a quick-release impeller shaft device. Background Technology

[0002] Turbomachinery occupies a very important position in the national economy, especially in the entire heavy industry system. In recent years, with the development of micro-machining and precision machining processes, micro-miniature turbomachinery has achieved rapid development and is widely used in fields such as micro turbojet engines, micro gas generators, and automotive turbochargers. An impeller is a driven machine that relies on a drive shaft to input mechanical energy to increase gas pressure and discharge gas.

[0003] Existing technology requires disassembling the impeller shaft and replacing the bearing on the shaft. This requires removing the entire shaft housing from the shaft and using tools to remove the bearing from both ends. The disassembly process is complex, cumbersome, and labor-intensive, reducing the efficiency of the workers. Therefore, a quick-release impeller shaft device is proposed. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide an impeller quick-release shaft device to solve the technical problems mentioned in the background.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a quick-release impeller shaft device, comprising a shaft seat, a shaft installed inside the shaft seat, end caps on both sides of the curved outer wall of the shaft, and a quick-release assembly on one side of the end cap;

[0006] The quick-release assembly includes a cover plate bolted to the end cap. A rotating ring is rotatably connected to the side of the cover plate away from the end cap. Four sets of arc-shaped inclined blocks are arranged circumferentially on the inner wall of the rotating ring near the cover plate. Each of the four sets of arc-shaped inclined blocks abuts against a long shaft on one side. A connecting block for sliding the long shaft is provided inside the end cap. A first inclined block is fixed to the end of the long shaft away from the arc-shaped inclined blocks. A matching second inclined block is provided on one side of the first inclined block. A support plate is fixed to one side of the second inclined block. A return spring is installed at the top of the support plate.

[0007] As a preferred technical solution, the outer wall of the rotating shaft is fitted with a bearing located inside the end cover.

[0008] As a preferred technical solution, one side of the arc-shaped inclined block is provided with a spring ball shaft fixed to one side of the rotating ring, and one side of the cover plate is provided with a limiting groove that matches the spring ball shaft.

[0009] As a preferred technical solution, one end of the reset spring is fixed to the support plate, and the other end of the reset spring is fixed to the connecting block.

[0010] As a preferred technical solution, one side of the second inclined block and the bearing side are on the same horizontal plane.

[0011] As a preferred technical solution, the bearing has an abutment ring attached to the side near the cover plate, the abutment ring has an annular groove inside, and a threaded rod is slidably connected inside the annular groove.

[0012] As a preferred technical solution, one side of the threaded rod passes through the rotating ring, and the cover plate is provided with an arc-shaped groove for the threaded rod to move.

[0013] In summary, the present invention has the following main advantages:

[0014] This invention utilizes the rotation of a rotating ring to abut against a long shaft via the inclined surface of an arc-shaped block. The long shaft then moves downwards through the first and second inclined blocks until one side of the second inclined block abuts against the bearing. Subsequently, pulling the shaft seat and cover plate allows the four sets of second inclined blocks on one side of the bearing to push the bearing along one side of the rotating shaft until both sets of bearings are completely disengaged. This effectively eliminates the need for separate bearing removal, thus improving the efficiency of bearing removal and replacement, achieving a quick-release effect. Adjusting the threaded rod allows for effective fitting and limiting of bearings of different thicknesses, enabling the replacement of bearings of different thicknesses based on the wear condition of the rotating shaft, enhancing the applicability of the device.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] The embodiments of this utility model will be described below based on its overall structure.

[0026] A quick-release impeller shaft device, such as Figure 1-7 As shown, it includes a bearing seat 100, a rotating shaft 120 is installed inside the bearing seat 100, and end caps 110 are provided on both sides of the curved outer wall of the rotating shaft 120. A quick-release assembly 200 is provided on one side of the end cap 110.

[0027] The quick-release assembly 200 includes a cover plate 210 bolted to the end cover 110. A rotating ring 220 is rotatably connected to the side of the cover plate 210 away from the end cover 110. Four sets of arc-shaped inclined blocks 230 are arranged circumferentially on the inner wall of the rotating ring 220 near the cover plate 210. A long shaft 240 is abutted on one side of each of the four sets of arc-shaped inclined blocks 230. A connecting block 250 for sliding the long shaft 240 is provided inside the end cover 110. A first inclined block 260 is fixed to the end of the long shaft 240 away from the arc-shaped inclined blocks 230. A second inclined block 270 is provided on one side of the first inclined block 260. A support plate 280 is fixed to one side of the second inclined block 270. A return spring 290 is installed on the top of the support plate 280.

[0028] When it is necessary to remove and replace the bearing 130 on the rotating shaft 120, remove the bolts between the end cover 110 and the cover plate 210. Then, by rotating the rotating ring 220, the rotating ring 220 drives the arc-shaped inclined block 230 to rotate synchronously. The inclined surface on the arc-shaped inclined block 230 abuts against the long shaft 240, thereby causing the long shaft 240 to move to one side. The long shaft 240 drives the first inclined block 260 to move, causing the first inclined block 260 to abut against the second inclined block 270 and move it downwards. The second inclined block 270 drives... The support plate 280 and the tension return spring 290 move synchronously until one side of the second inclined block 270 abuts against the bearing 130. Then, the shaft seat 100 and the cover plate 210 are pulled. The four sets of second inclined blocks 270 on one side of the bearing 130 can push the bearing 130 to slide along one side of the rotating shaft 120 until the two sets of bearings 130 are completely separated from the rotating shaft 120. This effectively eliminates the need for the subsequent separate removal of the bearing 130, thereby improving the efficiency of removing and replacing the bearing 130 and achieving a quick removal effect.

[0029] Please refer to this carefully. Figure 2 , Figures 4 to 6 The outer wall of the curved surface of the rotating shaft 120 is fitted with a bearing 130 located inside the end cover 110. One side of the second inclined block 270 is on the same horizontal plane as one side of the bearing 130. One end of the return spring 290 is fixed to the support plate 280, and the other end of the return spring 290 is fixed to the connecting block 250.

[0030] The second inclined block 270 can be used to make it fit against the bearing 130. The return spring 290 can be used to make the first inclined block 260 press the second inclined block 270 to move and then return to its original position.

[0031] Please refer to this carefully. Figures 3 to 5 The arc-shaped inclined block 230 has a spring ball shaft 221 fixed to one side of the rotating ring 220, and the cover plate 210 has a limiting groove 222 that matches the spring ball shaft 221.

[0032] The spring ball shaft 221 and the limiting groove 222 work together to effectively limit the rotation ring 220.

[0033] Please refer to this carefully. Figure 1 , Figure 4 and Figure 7 The bearing 130 has an abutment ring 291 attached to the side near the cover plate 210. The abutment ring 291 has an annular groove 293 inside. A threaded rod 292 is slidably connected inside the annular groove 293. One side of the threaded rod 292 passes through the rotating ring 220. The cover plate 210 has an arc-shaped groove 294 for the threaded rod 292 to move.

[0034] By rotating the threaded rods 292 on both sides, the threaded rods 292 drive the abutment ring 291 to fit against one side of the bearing 130. By adjusting the threaded rods 292, the bearings 130 of different thicknesses can be effectively fitted and limited, so that bearings 130 of different thicknesses can be replaced according to the wear of the rotating shaft 120, thereby enhancing the applicability of the device.

[0035] In use, by rotating the rotating ring 220, the inclined surface on the arc-shaped inclined block 230 abuts against the long shaft 240, causing the long shaft 240 to abut against the first inclined block 260 and the second inclined block 270 and move downward until one side of the second inclined block 270 abuts against the bearing 130. Then, the shaft seat 100 and the cover plate 210 are pulled, and the four sets of second inclined blocks 270 on one side of the bearing 130 can push the bearing 130 to slide along one side of the rotating shaft 120 until the two sets of bearings 130 are completely separated from the rotating shaft 120. This effectively eliminates the need for subsequent separate removal of the bearing 130, thereby improving the efficiency of removing and replacing the bearing 130 and achieving a quick removal effect. By adjusting the threaded rod 292, bearings 130 of different thicknesses can be effectively fitted and limited, allowing the replacement of bearings 130 of different thicknesses according to the wear condition of the rotating shaft 120, thus enhancing the applicability of the device. All parts not mentioned in this device are the same as or can be implemented using existing technology.
