Description

Technical Field

[0001] This application relates to the field of gearboxes, and more particularly to a gearbox motor. Background Technology

[0002] Currently, one type of gearbox motor uses a DC motor driven by a worm gear. The gear transmission reduces the speed and acts on an output shaft. The rotation of the output shaft simultaneously drives the coupling at the other end, thus achieving the purpose of the DC motor driving the coupling. The gearbox motor's housing consists of two injection-molded shell structures. Both the DC motor and the gear transmission system are installed inside the shell. After the internal components are assembled, the shell is covered and secured with waterproof adhesive and screws to form a sealed space.

[0003] When installing a motor in existing gearboxes, the process typically involves setting a side lug on the gearbox, then welding a connecting assembly to the corresponding motor to secure the motor to the gearbox. Welding the connecting assembly to the motor means that when replacing the motor, the original motor's connecting assembly needs to be disassembled, and a new connecting assembly needs to be welded onto the new motor. This makes connecting the motor and gearbox very inconvenient. Furthermore, existing gearboxes require periodic lubrication, usually by removing the top cover before adding lubricant and then reinstalling it, which is also quite inconvenient. Utility Model Content

[0004] To address the inconvenience of connecting the motor to the gearbox and the difficulty of adding lubricating oil, this application provides a gearbox motor.

[0005] The gearbox motor provided in this application adopts the following technical solution: it includes a housing and a motor body. A housing cover is fixed to the top of the housing, and a mounting base is fixed to the top of the housing cover. A limit mechanism is provided inside the mounting base. A first gear and a second gear are rotatably connected to the bottom of the inner wall of the housing. A third gear is fixed to the top of the second gear. A fourth gear is rotatably connected to the bottom of the housing cover. A rotating shaft is fixed to the middle of the fourth gear. The rotating shaft moves through the bottom of the outer wall of the housing. A connecting cover is fixed to the bottom of the motor body. Connecting holes are provided through the four corners of the top of the connecting cover.

[0006] By adopting the above technical solution and adjusting the upper limit mechanism of the mounting base to make the limit mechanism compatible with the connecting cover of the motor body, the power output end of the motor body can pass through the connecting cover through the connecting hole when installing the motor body.

[0007] Preferably, the limiting mechanism includes a worm gear, which is rotatably connected to the bottom of the inner wall of the mounting base. A worm is rotatably connected through one side of the mounting base, and the worm meshes with the worm gear. A knob is fixed at one end of the worm.

[0008] By adopting the above technical solution, the worm gear is rotated by turning the knob, which in turn drives the worm wheel to rotate.

[0009] Preferably, a connecting disc is fixed to the top of the worm gear, and a guide rail is fixed to the top of the connecting disc. The guide rail is arranged in a horizontal spiral shape, and a slider is slidably connected inside the guide rail. A circular hole is passed through the center of the top of the worm gear, the connecting disc, and the mounting base.

[0010] By adopting the above technical solution, the connecting disc is rotated by the worm gear, which in turn drives the guide rail to rotate. The slider slides on the spiral guide rail, allowing the slider to move horizontally.

[0011] Preferably, four sliders are provided, and a connecting block is fixed to the top of each of the four sliders. Each of the four connecting blocks movably passes through the top of the mounting base and is slidably connected to the top of the mounting base. A threaded hole is provided on the top of the connecting block, and the threaded hole is used in conjunction with the connecting hole.

[0012] By adopting the above technical solution, four sliders slide simultaneously on the mounting base, so that the four sliders are located below the four connecting holes. Bolts are used to pass through the connecting holes and connect with the threaded holes to fix the connecting cover on the mounting base.

[0013] Preferably, the first gear meshes with the second gear, and the third gear meshes with the fourth gear. The diameters of the first gear, second gear, third gear, and fourth gear, from smallest to largest, are the third gear, first gear, fourth gear, and second gear, respectively. The central axis of the third gear is collinear with the central axis of the second gear.

[0014] By adopting the above technical solution, the motor body drives the first gear to rotate, which in turn drives the second gear to rotate. The second and third gears rotate at the same speed, which in turn drives the fourth gear and the rotating shaft to rotate slowly.

[0015] Preferably, the top of the cover has a through hole, the power output end of the motor body is fixed with a plug rod, the plug rod passes through the middle of the through hole, and the middle of the first gear has a plug hole, the plug rod and the plug hole are used together.

[0016] By adopting the above technical solution, when installing the motor body, the plug rod passes through the through hole and is inserted into the plug hole. The rotation of the motor body drives the plug rod and the first gear to rotate.

[0017] Preferably, the top of the cover has a through-hole for oiling. There are two oiling holes. One of the oiling holes has an oil guide pipe fixed at its bottom, and the other oiling hole is located at the top of the meshing point of the third and fourth gears. The bottom end of the oil guide pipe is located at the top of the meshing point of the first and second gears.

[0018] By adopting the above technical solution, when maintenance is required, lubricating oil can be dripped directly into the two oil injection holes. The lubricating oil can flow to the meshing points of the third and fourth gears, as well as the meshing points of the first and second gears, thereby applying lubricating oil to the first, second, third, and fourth gears.

[0019] In summary, this application includes at least the following beneficial technical effects:

[0020] 1. This application adjusts the position of the slider according to the size of the motor body connecting cover. By rotating the knob, the worm gear is rotated, which in turn rotates the connecting plate, which in turn rotates the guide rail, causing the slider to move horizontally. The four sliders are adjusted to be below the four connecting holes. Bolts are passed through the connecting holes and connected to the threaded holes to fix the connecting cover on the mounting base. When replacing the motor body, the bolts are loosened and the knob is readjusted, thus achieving a more convenient connection between the motor and the gearbox.

[0021] 2. When maintenance is required, the lubricating oil can be dripped directly into the two oil filling holes. The lubricating oil can flow to the meshing points of the third and fourth gears, as well as the meshing points of the first and second gears, thereby applying lubricating oil to the first, second, third, and fourth gears, thus making subsequent maintenance very convenient.

The rotating shaft 15 moves through the bottom of the outer wall of the housing 1. A connecting cover 3 is fixed to the bottom of the motor body 2. By adjusting the upper limiting mechanism of the mounting base 16, the limiting mechanism is adapted to the connecting cover 3 of the motor body 2. Connecting holes 4 are opened through the four corners of the top of the connecting cover 3. When installing the motor body 2, the power output end of the motor body 2 can pass through the connecting holes 4 through the connecting cover 3.

[0031] Reference Appendix Figure 3 The limiting mechanism includes a worm gear, which is rotatably connected to the bottom of the inner wall of the mounting base 16. A worm 17 is rotatably connected through one side of the mounting base 16. The worm 17 meshes with the worm gear. A knob 18 is fixed at one end of the worm 17. By rotating the knob 18, the worm 17 is driven to rotate, which in turn drives the worm gear to rotate.

[0032] Reference Appendix Figure 3 The worm gear has a connecting plate 19 fixed to its top, and a guide rail 20 fixed to its top. The guide rail 20 is arranged in a horizontal spiral shape, and a slider 21 is slidably connected inside the guide rail 20. Circular holes are passed through the middle of the top of the worm gear, the connecting plate 19, and the mounting base 16. The worm gear drives the connecting plate 19 to rotate, which in turn drives the guide rail 20 to rotate. The slider 21 slides on the spiral guide rail 20, so that the slider 21 moves horizontally.

[0033] Reference Appendix Figure 1 and 4The system includes four sliders 21, each with a connecting block 22 fixed to its top. The four connecting blocks 22 movably pass through the top of the mounting base 16 and slide to connect with it. The top of each connecting block 22 has a threaded hole 23, which is used in conjunction with the connecting hole 4. The four sliders 21 slide simultaneously on the mounting base 16, so that the four sliders 21 are located below the four connecting holes 4. Bolts are used to pass through the connecting holes 4 and connect with the threaded holes 23 to fix the connecting cover 3 to the mounting base 16.

[0034] Reference Appendix Figure 5 The first gear 10 meshes with the second gear 12, and the third gear 13 meshes with the fourth gear 14.

The central axis of the third gear 13 is collinear with the central axis of the second gear 12. The motor body 2 drives the first gear 10 to rotate, which in turn drives the second gear 12 to rotate. The second gear 12 and the third gear 13 rotate at the same speed, which in turn drives the fourth gear 14 and the rotating shaft 15 to rotate slowly.

[0035] Reference Appendix Figure 2 The top of the cover 5 has a through hole 8, and the power output end of the motor body 2 is fixed with a plug rod 9. The plug rod 9 passes through the middle of the through hole 8, and the middle of the first gear 10 has a plug hole 11. The plug rod 9 and the plug hole 11 are used together. When the motor body 2 is installed, the plug rod 9 passes through the through hole 8 and is inserted into the plug hole 11. The rotation of the motor body 2 drives the plug rod 9 and the first gear 10 to rotate.

[0036] Reference Appendix Figure 6 The top of the cover 5 has a through-hole 6 for oiling. There are two oiling holes 6. One oiling hole 6 has an oil guide tube 7 fixed at the bottom. The other oiling hole 6 is located at the top of the meshing point of the third gear 13 and the fourth gear 14. The bottom end of the oil guide tube 7 is located at the top of the meshing point of the first gear 10 and the second gear 12. When maintenance is required, lubricating oil can be dripped directly into the two oiling holes 6. The lubricating oil can flow to the meshing point of the third gear 13 and the fourth gear 14, and the meshing point of the first gear 10 and the second gear 12, thereby applying lubricating oil to the first gear 10, the second gear 12, the third gear 13 and the fourth gear 14.

[0037] The implementation principle of a gearbox motor according to this application embodiment is as follows: First, adjust the position of the slider 21 according to the size of the connecting cover 3 of the motor body 2. Rotate the knob 18 to drive the worm gear 17 to rotate, which in turn drives the worm wheel to rotate. The worm wheel drives the connecting plate 19 to rotate, which in turn drives the guide rail 20 to rotate. The slider 21 slides on the spiral guide rail 20, allowing it to move horizontally. All four sliders 21 slide simultaneously on the mounting base 16, positioning them below the four connecting holes 4. Bolts are passed through the connecting holes 4 and connected to the threaded holes 23 to fix the connecting cover 3 to the mounting base 16. When replacing the motor body 2, loosen... Simply unscrew and readjust knob 18. When connecting motor body 2, insert rod 9 passes through through hole 8 and inserts into insertion hole 11. The rotation of motor body 2 drives insert rod 9 and first gear 10 to rotate, which in turn drives second gear 12 to rotate. Second gear 12 and third gear 13 rotate at the same speed, which in turn drives fourth gear 14 and rotating shaft 15 to rotate slowly. When maintenance is required, lubricating oil can be dripped directly into the two oil filling holes 6. The lubricating oil can flow to the meshing points of third gear 13 and fourth gear 14, and the meshing points of first gear 10 and second gear 12, thereby applying lubricating oil to first gear 10, second gear 12, third gear 13 and fourth gear 14.
