[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides an adjustable gap double gear structure and its adjustment method, which solves the problem that gears tend to rotate when the equipment is not in use.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: an adjustable clearance double gear structure, including a mounting base with mounting holes, a gearbox on the top of the mounting base, a first opening on the top of the gearbox, a motor on one side of the bottom of the gearbox, the output end of the motor being connected to one end of a first rotating shaft, the other end of the first rotating shaft extending out of the gearbox through the first opening, a first gear on the first rotating shaft, a first electric telescopic rod connected to one end of the gearbox on one side of the gearbox, a sliding block connected to one end of the sliding block with a threaded groove, a threaded post on the threaded groove, a bearing on the top of the threaded post, a second rotating shaft on the bearing, and one end of the second rotating shaft being disposed on the bearing. The gearbox has a second rotating shaft extending out of the first opening at one end. A second gear is mounted on the second rotating shaft. A smooth layer is provided at the bottom of the gearbox. The bottom of the sliding block contacts the smooth layer. A groove is provided on one side of the gearbox. An electric slider is mounted on the groove. One end of the electric slider is mounted on the groove. The other end of the electric slider is connected to one end of a connecting plate. The bottom of the connecting plate is connected to one end of a second electric telescopic rod. The other end of the second electric telescopic rod is connected to one end of a long plate. A connecting block is provided at the bottom of the long plate. A damping groove is provided on the connecting block. The damping groove matches the second rotating shaft. A controller is provided on the other side of the gearbox. The controller is electrically connected to the first electric telescopic rod and to the motor.

[0008] To facilitate the application of lubricating oil, the present invention is improved in that the gearbox has an internal housing, one side of which is connected to the inside of the gearbox, a second opening is provided on the top of the housing, a cover plate is provided on the second opening, a sealing block is provided at the bottom of the cover plate, the sealing block matches the second opening, the bottom of the sealing block is connected to one end of a connecting rod, the other end of the connecting rod is connected to one end of the brush head, and a switch door is hinged to the front of the gearbox, and an electromagnetic lock is provided on the switch door.

[0009] To facilitate fixing the cover plate, the present invention is improved by providing electromagnets on both sides of the cover plate and iron blocks on both sides of the top of the box.

[0010] To facilitate lifting the cover plate, the present invention is improved by providing an auxiliary rod on the top of the cover plate.

[0011] To improve the sealing effect, the present invention is improved by using rubber material for the sealing block.

[0012] To simplify operation, the present invention is improved by wherein the controller is electrically connected to the electromagnet and the electric slider.

[0013] The present invention further provides a dual-gear adjustment method with adjustable clearance, comprising the following steps:

[0014] Step 1: First, install the equipment in the designated position using the mounting holes on the mounting base and external bolts.

[0015] Step 2: Then, start the first electric telescopic rod through the controller. The first electric telescopic rod drives the sliding block to move on the smooth layer. The sliding block will drive the second rotating shaft on the threaded column inside the threaded groove, which is set on the bearing, to move. Then, the second gear on the second rotating shaft meshes with the first gear on the first rotating shaft. Then, the designated parts of the external equipment are respectively installed on the first rotating shaft and the second rotating shaft that extend out of the gearbox through the first opening.

[0016] Step 3: Then start the motor through the controller. The motor drives the first rotating shaft to rotate, which in turn drives the first gear on the first rotating shaft to rotate. The first gear then drives the second gear to rotate, which in turn drives the second rotating shaft to rotate.

[0017] Step 4: When the external device is no longer needed, separate the designated position of the external device from the first and second rotating shafts. Then, use the first electric telescopic rod to separate the second gear from the first gear. Then, use the electromagnetic lock to open the switch door. Use the controller to control the electromagnet so that the electromagnet is no longer attracted to the iron block. Then, use the auxiliary rod to remove the cover plate from the second opening. The brush head on the connecting rod on the sealing block on the cover plate will come out of the box through the second opening. There is lubricating oil in the box, so there will be lubricating oil on the brush head. Then, use the brush head to apply the lubricating oil to the first rotating shaft, the first gear, the second rotating shaft, and the second gear.

[0018] Step 5: After the application is complete, place the brush head into the box, align the electromagnet with the iron block, and then activate the electromagnet through the controller to attract the iron block.

[0019] Step 6: When you want to inspect and repair the second rotating shaft and the second gear, open the switch door with the electromagnetic lock, and then turn the threaded post that is threaded to the threaded groove to separate the threaded post from the threaded groove. This will separate the second rotating shaft connected to the bearing on the threaded post from the sliding block. Then, take out the second rotating shaft connected to the bearing on the threaded post through the second opening. The second gear is set on the second rotating shaft, and the second gear will also come out of the gearbox along with the second rotating shaft, which will facilitate the inspection and repair of the second rotating shaft and the second gear. After inspection, install it into the threaded groove on the sliding block.

[0020] Step 7: Then, control the electric slider to move upward on the slide groove, thereby driving the connecting block on the long plate of the second electric telescopic rod on the connecting plate to move upward. Then, use the second electric telescopic rod to align the damping groove on the connecting block on the long plate with the second rotating shaft. Then, control the electric slider to move downward on the slide groove, thereby driving the damping groove on the connecting block on the long plate of the second electric telescopic rod on the connecting plate to move downward, so that the damping groove engages with the second rotating shaft, thereby preventing the second rotating shaft from driving the second gear to rotate.

[0021] (III) Beneficial Effects

[0022] Compared with the prior art, the present invention provides the following beneficial effects:

[0023] The adjustable gap double gear structure and its adjustment method, via a controller, activate a first electric telescopic rod. This rod moves a sliding block on a smooth surface, causing the sliding block to move a second rotating shaft mounted on a bearing inside a threaded groove. The second gear on the second rotating shaft meshes with the first gear on the first rotating shaft. Designated parts of external equipment are then installed on the first and second rotating shafts, which extend from the gearbox through a first opening. The controller then activates a motor, which drives the first rotating shaft to rotate. This causes the first gear on the first rotating shaft to rotate, which in turn drives the second gear to rotate, thus causing the second gear to... The second rotating shaft rotates, thereby driving the external equipment to rotate via the first and second rotating shafts. When the external equipment is no longer needed, its designated position is separated from the first and second rotating shafts. Then, the second gear is separated from the first gear via the first electric telescopic rod. The door is then opened via an electromagnetic lock. The controller controls the electromagnet to prevent it from attracting the iron block. The cover plate is then removed from the second opening via an auxiliary rod. The brush head on the connecting rod of the sealing block on the cover plate then exits through the second opening into the housing. The housing contains lubricating oil, which is then applied to the brush head. The brush head then applies the lubricating oil to the first rotating shaft, the first gear, and the second... The second rotating shaft and the second gear provide lubrication. After application, the brush head is placed into the housing, and the electromagnet is aligned with the iron block. The electromagnet is then activated by the controller, attracting the iron block and fixing the cover plate to the housing. For inspection and maintenance of the second rotating shaft and the second gear, the switch door is opened via the electromagnetic lock. The threaded post connected to the threaded groove is then turned, separating it from the groove. This allows the second rotating shaft connected to the bearing on the threaded post to be separated from the sliding block. The second rotating shaft connected to the bearing on the threaded post can then be removed through the second opening. The second gear is mounted on the second rotating shaft, and it will follow the first gear... The second rotating shaft exits from the gearbox, facilitating inspection and maintenance of the second rotating shaft and the second gear. After inspection, it is installed into the threaded groove on the sliding block. Then, the controller controls the electric slider to move upward on the groove, thereby driving the connecting block on the long plate of the second electric telescopic rod on the connecting plate to move upward. Then, the second electric telescopic rod aligns the damping groove on the connecting block on the long plate with the second rotating shaft. Then, the controller controls the electric slider to move downward on the groove, thereby driving the damping groove on the connecting block on the long plate of the second electric telescopic rod on the connecting plate to move downward, thus engaging the damping groove with the second rotating shaft, thereby preventing the second rotating shaft from driving the second gear to rotate.

[0031] Furthermore, electromagnets 26 are provided on both sides of the cover plate 25, and iron blocks 27 are provided on both sides of the top of the box body 23 to facilitate fixing the cover plate 25.

[0032] In this embodiment, the top of the cover plate 25 is provided with an auxiliary rod 31 to facilitate lifting the cover plate 25.

[0033] In this embodiment, the sealing block 28 is made of rubber, which can improve the sealing effect.

[0034] Furthermore, the controller 32 is electrically connected to the electromagnet 26 and the electric slider 17, which simplifies operation.

[0035] The present invention further provides a dual-gear adjustment method with adjustable clearance, comprising the following steps:

[0036] Step 1: First, install the equipment in the designated position using the mounting holes 2 on the mounting base 1 and the external bolts.

[0037] Step 2: Then, the first electric telescopic rod 8 is activated by the controller 32. The first electric telescopic rod 8 drives the sliding block 9 to move on the smooth layer 10. As a result, the sliding block 9 drives the second rotating shaft 14, which is mounted on the bearing 13, on the threaded column 12 inside the threaded groove 11. Then, the second gear 15 on the second rotating shaft 14 meshes with the first gear 7 on the first rotating shaft 6. Then, the designated parts of the external equipment are respectively installed on the first rotating shaft 6 and the second rotating shaft 14, which extend out of the gearbox 3 through the first opening 4.

[0038] Step 3: Then, start the motor 5 through the controller 32. The motor 5 drives the first rotating shaft 6 to rotate, which in turn drives the first gear 7 on the first rotating shaft 6 to rotate. The first gear 7 drives the second gear 15 to rotate, which in turn drives the second rotating shaft 14 to rotate.

[0039] Step 4: When the external device is no longer needed, separate the designated position of the external device from the first rotating shaft 6 and the second rotating shaft 14. Then, use the first electric telescopic rod 8 to separate the second gear 15 from the first gear 7. Then, use the electromagnetic lock 34 to open the switch door 33. Use the controller 32 to control the electromagnet 26 so that the electromagnet 26 is no longer attracted to the iron block 27. Then, use the auxiliary rod 31 to remove the cover plate 25 from the second opening 24. The brush head 30 on the connecting rod 29 on the sealing block 28 on the cover plate 25 will come out of the box 23 through the second opening 24. There is lubricating oil in the box 23, so there will be lubricating oil on the brush head 30. Then, use the brush head 30 to apply the lubricating oil to the first rotating shaft 6, the first gear 7, the second rotating shaft 14, and the second gear 15.

[0040] Step 5: After the application is complete, place the brush head 30 into the housing 23, then align the electromagnet 26 with the iron block 27, and then activate the electromagnet 26 through the controller 32, so that the iron block 27 is attracted by the electromagnet 26.

[0041] Step 6: When you want to inspect and repair the second rotating shaft 14 and the second gear 15, open the switch door 33 through the electromagnetic lock 34, and then turn the threaded post 12 that is threadedly connected to the threaded groove 11 to separate the threaded post 12 from the threaded groove 11. This allows you to separate the second rotating shaft 14, which is connected to the bearing 13 on the threaded post 12, from the sliding block 9. Then, take out the second rotating shaft 14, which is connected to the bearing 13 on the threaded post 12, through the second opening 24. The second gear 15 is set on the second rotating shaft 14, and the second gear 15 will also come out of the gearbox 3 along with the second rotating shaft 14, making it convenient to inspect and repair the second rotating shaft 14 and the second gear 15. After inspection, install them into the threaded groove 11 on the sliding block 9.

[0042] Step 7: Then, the controller 32 controls the electric slider 17 to move upward on the slide groove 16, thereby driving the connecting block 21 on the long plate 20 of the second electric telescopic rod 19 on the connecting plate 18 to move upward. Then, the second electric telescopic rod 19 aligns the damping groove 22 on the connecting block 21 on the long plate 20 with the second rotating shaft 14. Then, the controller 32 controls the electric slider 17 to move downward on the slide groove 16, thereby driving the damping groove 22 on the connecting block 21 on the long plate 20 of the second electric telescopic rod 19 on the connecting plate 18 to move downward, so that the damping groove 22 engages with the second rotating shaft 14, thereby preventing the second rotating shaft 14 from driving the second gear 15 to rotate.

[0043] In summary, the working principle and process of this adjustable clearance double gear structure and its adjustment method are as follows: First, the equipment is installed in the designated position using the mounting holes 2 on the mounting base 1 and external bolts. Then, the controller 32 activates the first electric telescopic rod 8, which drives the sliding block 9 to move on the smooth layer 10. This causes the sliding block 9 to move the second rotating shaft 14, which is mounted on the bearing 13 and located on the threaded post 12 inside the threaded groove 11. Then, the second gear 15 on the second rotating shaft 14 meshes with the first gear 7 on the first rotating shaft 6. Finally, the designated parts of the external equipment are respectively installed on the first rotating shaft 6 and the second rotating shaft 14, which extend from the gearbox 3 through the first opening 4. Then, the controller 32 starts the motor 5, which drives the first rotating shaft 6 to rotate. This causes the first gear 7 on the first rotating shaft 6 to rotate, which in turn drives the second gear 15 to rotate. The second gear 15 then drives the second rotating shaft 14 to rotate, thus enabling the external equipment to rotate via the first and second rotating shafts 6 and 14. When the external equipment is no longer needed, its designated position is separated from the first and second rotating shafts 6 and 14. Then, the first electric telescopic rod 8 separates the second gear 15 from the first gear 7. The electromagnetic lock 34 then opens the switch door 33. The controller 32 controls the electromagnet 26 to prevent it from attracting the iron block 27. Then, the auxiliary rod 3... 1. Remove the cover plate 25 from the second opening 24. The brush head 30 on the connecting rod 29 of the sealing block 28 on the cover plate 25 will then exit through the second opening 24 into the housing 23. The housing 23 contains lubricating oil, which will also be present on the brush head 30. The brush head 30 will then apply the lubricating oil to the first rotating shaft 6, the first gear 7, the second rotating shaft 14, and the second gear 15, achieving a lubrication effect. After application, place the brush head 30 back into the housing 23. Align the electromagnet 26 with the iron block 27, and activate the electromagnet 26 via the controller 32. The electromagnet 26 will then attract the iron block 27, thus fixing the cover plate 25 to the housing 23. When it is necessary to inspect or repair the second rotating shaft 14 and the second gear 15... When the electromagnetic lock 34 is used to open the switch door 33, the threaded post 12 connected to the threaded groove 11 is turned, thereby separating the threaded post 12 from the threaded groove 11. This allows the second rotating shaft 14, which is connected to the bearing 13 on the threaded post 12, to be separated from the sliding block 9. Then, the second rotating shaft 14 connected to the bearing 13 on the threaded post 12 is taken out through the second opening 24. The second gear 15 is set on the second rotating shaft 14, so the second gear 15 will also come out of the gearbox 3 along with the second rotating shaft 14, which facilitates the inspection and maintenance of the second rotating shaft 14 and the second gear 15. After inspection, it is installed into the threaded groove 11 on the sliding block 9. Then, the controller 32 controls the electric slider 17 to move upward on the slide groove 16.This causes the connecting block 21 on the long plate 20 of the second electric telescopic rod 19 on the connecting plate 18 to move upward. Then, the second electric telescopic rod 19 aligns the damping groove 22 on the connecting block 21 on the long plate 20 with the second rotating shaft 14. Then, the controller 32 controls the electric slider 17 to move downward on the slide groove 16, thereby causing the damping groove 22 on the connecting block 21 on the long plate 20 of the second electric telescopic rod 19 on the connecting plate 18 to move downward. This causes the damping groove 22 to engage with the second rotating shaft 14, preventing the second rotating shaft 14 from driving the second gear 15 to rotate.

Step 5: After the application is completed, put the brush head (30) into the box (23), then align the electromagnet (26) with the iron block (27), and then start the electromagnet (26) through the controller (32) so that the iron block (27) is attracted by the electromagnet (26); Step 6: When you want to inspect and repair the second rotating shaft (14) and the second gear (15), open the switch door (33) through the electromagnetic lock (34), and then turn the threaded post (12) that is threadedly connected to the threaded groove (11) to separate the threaded post (12) from the threaded groove (11). This allows you to separate the second rotating shaft (14) connected to the bearing (13) on the threaded post (12) from the sliding block (9). Then, take out the second rotating shaft (14) connected to the bearing (13) on the threaded post (12) through the second opening (24). The second gear (15) is set on the second rotating shaft (14), so the second gear (15) will also come out of the gearbox (3) along with the second rotating shaft (14), which makes it convenient to inspect and repair the second rotating shaft (14) and the second gear (15). After inspection, install it into the threaded groove (11) on the sliding block (9). Step 7: Then, the controller (32) controls the electric slider (17) to move upward on the slide groove (16), thereby driving the connecting block (21) on the long plate (20) of the second electric telescopic rod (19) on the connecting plate (18) to move upward. Then, the second electric telescopic rod (19) aligns the damping groove (22) on the connecting block (21) on the long plate (20) with the second rotating shaft (14). Then, the controller (32) controls the electric slider (17) to move downward on the slide groove (16), thereby driving the damping groove (22) on the connecting block (21) on the long plate (20) of the second electric telescopic rod (19) on the connecting plate (18) to move downward, thereby engaging the damping groove (22) with the second rotating shaft (14), thus preventing the second rotating shaft (14) from driving the second gear (15) to rotate.
