Detailed implementation manners

[0031] The following describes in detail the specific implementation manners of the present invention with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0032] In the present invention, unless otherwise stated, the orientation terms such as "upper, lower, inner, outer" included in the terms only represent the orientation of the terms in the normal use state, or the common names understood by those skilled in the art, and should not be regarded as a limitation of the terms.

[0033] Referring to Figures 1-7 As shown, a detachable composite end gear disk, the end gear disk includes: a fixed shaft 300 and a first end gear disk 100 and a second end gear disk 200 respectively sleeved on the fixed shaft 300; wherein, one end of the fixed shaft 300 is provided with a retaining cover 401 to abut against the second end gear disk 200, the middle part of the fixed shaft 300 is detachably sleeved with a fixing ring 402 for limiting the first end gear disk 100, and a locking assembly 500 for locking the fixing ring 402 is further arranged on the fixing ring 402; the locking member 500 includes: a plurality of inserting blocks 504, and each inserting block 504 can be rotatably inserted into a corresponding first limiting hole 505 on the side surface of the fixed shaft 300.

[0034] During installation, place the bottom surface of the fixed shaft 300 facing upwards, and pass it through the first end gear disc 100 and the second end gear disc 200 in sequence from bottom to top. Use the retaining cover 401 on the fixed shaft 300 to initially fix the fixed shaft 300 during the assembly process to prevent it from slipping out of the first end gear disc 100. Fix the retaining cover 401 to the bottom surface of the second end gear disc 200 to ensure firmness and no looseness. Then, slide the fixing ring 402 onto the top of the fixed shaft 300 and axially slide it to an appropriate position so that the insertion block 504 cooperates with the first limiting hole 505 on the fixed shaft 300 to complete the fixed connection, enabling the composite end gear disc to be easily disassembled when maintenance or component replacement is required, reducing the maintenance cost and time.

[0035] Refer to Figures 4-7 As shown, the locking assembly 500 further includes: a slide rod 503; wherein, a plurality of sliding grooves 510 are distributed on the surface of the fixing ring 402 along its circumferential direction. A slide rod 503 is slidably sleeved in each sliding groove 510. The bottom surface of each slide rod 503 is fixedly provided with an insertion block 504. The surface of the fixed shaft 300 is provided with a first limiting hole 505 corresponding to and cooperating with each insertion block 504. The fixing ring 402 is provided with a driving member for driving the slide rod 503 to slide in the sliding groove 510.

[0036] During use, use the driving member on the fixing ring 402 to drive the slide rod 503 to slide in the sliding groove 510. As the slide rod 503 slides, the insertion block 504 gradually approaches the first limiting hole 505 on the fixed shaft 300. When the insertion block 504 is aligned with the first limiting hole 505, continue to drive the slide rod 503 to completely insert it into the first limiting hole 505, thereby realizing the locking of the fixed shaft 300, achieving the firm fixation of the fixed shaft 300, enhancing the overall stability and reliability of the composite end gear disc, preventing it from falling off during the working process. The locking assembly 500 and the fixing ring 402 cooperate with the fixed shaft 300, the first end gear disc 100, and the second end gear disc 200 to jointly complete the fixation and limitation of the composite end gear disc.

[0037] Refer to Figures 6-7 As shown, the driving member includes: a locking ring 501; the locking ring 501 is rotatably arranged on the upper surface of the fixing ring 402 and is coaxially arranged with the fixing ring 402. A plurality of groups of arc-shaped guiding grooves 502 corresponding to the sliding grooves 510 are formed on the surface of the locking ring 501 along its circumferential direction. The slide rod 503 is simultaneously slidably sleeved in the guiding grooves 502. The surface of the locking ring 501 is provided with a locking member for locking the locking ring 501.

[0038] In the above solution, the arc design of the guiding groove 502 enables the sliding rod 503 to slide in the sliding groove 510 along a specific direction when the rotating locking ring 501 is rotated. During use, rotate the locking ring 501 to move it along the circumferential direction. During the rotation process, the arc design of the guiding groove 502 will guide the sliding rod 503 to slide in the sliding groove 510. As the locking ring 501 rotates, the sliding rod 503 drives the inserting block 504 to gradually approach and finally insert into the first limiting hole 505 on the fixed shaft 300, realizing the locking of the fixed shaft 300. When disassembly or maintenance is required, simply release the locking state of the locking ring 501 and rotate it to the unlocking position to easily disassemble components such as the fixed shaft 300, the first end tooth disc 100, and the second end tooth disc 200, improving the maintainability of the equipment.

[0039] Refer to Figure 7 As shown, the locking member includes: a fixed rod 506, a first limiting block 507, and a first spring 508; wherein, the fixed rod 506 is vertically and penetratingly arranged at the top of the locking ring 501, a first limiting block 507 is fixedly arranged at its top end, and its bottom end is slidably arranged in the second limiting hole 509. A plurality of the second limiting holes 509 are spaced apart and opened on the upper surface of the fixed ring 402. A first spring 508 is sleeved on the rod body of the fixed rod 506 outside the locking ring 501. One end of the first spring 508 is fixed on the first limiting block 507, and the opposite end is fixed on the top of the locking ring 501.

[0040] In the above solution, when it is necessary to lock the fixed shaft 300, manually rotate the locking ring 501 to an appropriate position so that the sliding rod 503 drives the inserting block 504 to insert into the first limiting hole 505. After the locking ring 501 rotates in place, make the bottom end of the fixed rod 506 slide into the second limiting hole 509 corresponding to the current locking position. At this time, release the first limiting block 507, and the restoring force of the first spring 508 will hold the fixed rod 506 in the second limiting hole 509, thereby locking the position of the locking ring 501. When disassembly or maintenance is required, simply perform the unlocking operation to disassemble components such as the locking ring 501 and the fixed shaft 300.

[0041] Refer to Figure 5 As shown, the end of the retaining cover 401 and the fixed shaft 300 are connected in a threaded manner.

[0042] In the above solution, the threaded connection between the retaining cover 401 and the fixed shaft 300 enables the position of the retaining cover 401 to be defined by the thread during installation, thereby adjusting the position of the second end tooth disc 200 so that several inserting blocks 504 can smoothly insert into the first limiting hole 505.

[0043] Refer to Figure 5As shown, a limiting ring 403 is arranged around a fixed shaft 300 on one side of the retaining cover 401 facing the second end gear disc 200. A limiting groove 404 adapted to the limiting ring 403 is arranged on the second end gear disc 200. A plurality of connecting columns 405 are fixedly arranged on the top surface of the second end gear disc 200. Connecting grooves 406 corresponding to and cooperating with the plurality of connecting columns 405 one by one are respectively formed on one side surface of the first end gear disc 100 in contact with the second end gear disc 200.

[0044] During installation, the fixed shaft 300 is sequentially passed through the first end gear disc 100 and the second end gear disc 200. At this time, the limiting ring 403 on the retaining cover 401 should face the second end gear disc 200. The second end gear disc 200 is brought close to the first end gear disc 100, so that the limiting ring 403 is aligned with the limiting groove 404 and inserted, realizing the preliminary positioning of the second end gear disc 200 in the vertical direction. The second end gear disc 200 is continuously pushed, so that the connecting columns 405 are aligned with the connecting grooves 406 on the first end gear disc 100 and inserted, realizing the connection and fixation of the two end gear discs in the horizontal direction. Through the cooperation of the limiting ring 403 and the limiting groove 404, the preliminary positioning and limiting of the second end gear disc 200 in the vertical direction are realized, preventing it from shifting or shaking during the subsequent assembly process. The plug-in cooperation of the connecting columns 405 and the connecting grooves 406 realizes the tight connection and fixation of the two end gear discs in the horizontal direction, ensuring the integrity and stability of the composite end gear disc.

[0045] Refer to Figures 4-5 As shown, the connecting column 405 is frustum-shaped.

[0046] In the above solution, the connecting column 405 is smaller at the upper end and larger at the lower end. During the installation process, the smaller end can more easily enter the installation hole, and as the pushing process progresses, the hole diameter is gradually enlarged, realizing smooth installation. This design reduces the resistance and friction during installation and reduces the installation difficulty.

[0047] In summary, for the detachable composite end gear disc provided by the present utility model, during use, place the bottom surface of the fixed shaft 300 upwards and pass it through the first end gear disc 100 and the second end gear disc 200 in sequence from bottom to top. Move the second end gear disc 200 closer to the first end gear disc 100, align the limit ring 403 with the limit groove 404 and insert it to achieve the preliminary positioning of the second end gear disc 200 in the vertical direction. Continue to push the second end gear disc 200 to align the connecting column 405 with the connecting groove 406 on the first end gear disc 100 and insert it, and threadedly limit the position of the retaining cover 401 to adjust the position of the second end gear disc 200. When it is necessary to lock the fixed shaft 300, manually rotate the locking ring 501 to move it in the circumferential direction. During the rotation, the arc-shaped design of the guiding groove 502 will guide the sliding rod 503 to slide in the sliding groove 510. As the locking ring 501 rotates, the sliding rod 503 drives the insertion block 504 to gradually approach and finally insert into the first limit hole 505 on the fixed shaft 300 to achieve the locking of the fixed shaft 300. At this time, release the first limit block 507, and the restoring force of the first spring 508 will keep the fixed rod 506 in the second limit hole 509, thereby locking the position of the locking ring 501.
