Description

Technical Field

[0001] This utility model relates to the field of gear assembly technology, specifically to a transmission gear assembly that is easy to disassemble. Background Technology

[0002] Gear transmission refers to a device that transmits motion and power through gear pairs. It is one of the most widely used mechanical transmission methods in modern equipment. It offers relatively accurate transmission, high efficiency, compact structure, reliable operation, and long service life.

[0003] Currently, most transmission gears are disassembled by simply unscrewing the nut on one side of the movable gear. However, during installation, it takes time to align the gears with the undisturbed ones, thus reducing the efficiency of disassembly and assembly.

[0004] Therefore, we propose to design a transmission gear assembly that is easy to disassemble. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0007] A detachable transmission gear assembly includes a base, a fixed frame fixedly connected to one top end of the base, a bracket fixedly connected to the top of the fixed frame, a rotating shaft connected to a bearing inside the bracket, a fixed gear fixedly connected to the outside of the rotating shaft, a column fixedly connected to the other top end of the base, a shaft seat fixedly connected to the top of the column, a mounting rod connected to a bearing inside the shaft seat, a positioning block fixedly connected to the outer wall of the mounting rod, a hexagonal key shaft provided in the middle of the mounting rod, a movable gear meshing with the fixed gear provided outside the hexagonal key shaft, and a locking nut threadedly connected to the end of the mounting rod.

[0008] The top of the bracket is provided with a limiting mechanism, which includes a limiting frame fixedly connected to the bracket. The top of the limiting frame is threaded with an adjusting bolt, and the bottom of the adjusting bolt passes through the limiting frame and is rotatably connected to a limiting plate.

[0009] As a preferred embodiment of the easily disassembled transmission gear assembly described in this utility model, one end of the rotating shaft passes through the fixing frame and is fixedly connected to an adapter, which facilitates connection with the drive shaft of external motors or other drive equipment.

[0010] As a preferred embodiment of the easily disassembled transmission gear assembly described in this utility model, the outer wall of the positioning block is provided with a platform, the platform and the top surface of the bracket are located on the same horizontal plane, and the bottom surface of the limiting plate is parallel to the top surface of the platform. When the limiting plate is pressed down on the top of the platform, it is convenient to position the mounting rod, thereby facilitating the removal of the movable gear.

[0011] As a preferred embodiment of the easily disassembled transmission gear assembly described in this utility model, the limiting frame has sliding grooves on both sides, and the limiting plate has limiting blocks fixedly connected to both sides. The limiting blocks are slidably connected to the inner wall of the sliding grooves, which facilitates limiting the lifting direction of the limiting plate.

[0012] As a preferred embodiment of the easily disassembled transmission gear assembly described in this utility model, two platforms are provided. The two platforms do not need to be arranged in parallel. In the design, it is only necessary to ensure that the fixed gear and the movable gear are in a meshing state when the limiting plate is pressed on the top of the platform.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention utilizes the interplay between a hexagonal key shaft, a mounting rod, and a limiting mechanism. By leveraging the self-locking characteristic of the external servo motor drive shaft of the fixed gear, the tooth position of the fixed gear is positioned. Then, the limiting plate presses down to limit the position of the mounting rod. This allows the movable gear in the transmission gear to be aligned via the sleeve of the hexagonal key shaft, replacing the original gear tooth meshing and eliminating the time required for gear alignment, thus effectively improving the efficiency of disassembly and assembly of the transmission gear.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0023] Please see Figure 1-3 This utility model provides a transmission gear assembly that is easy to disassemble, including a base 1, a fixing frame 2 fixedly connected to one end of the top of the base 1, a bracket 3 fixedly connected to the top of the fixing frame 2, and a rotating shaft 4 connected to the bearing inside the bracket 3.

[0024] In this embodiment, one end of the rotating shaft 4 passes through the fixing frame 2 and is fixedly connected to an adapter 401. The adapter 401 facilitates connection with the drive shaft of external motors and other drive devices.

[0025] A fixed gear 5 is fixedly connected to the outside of the rotating shaft 4. A column 6 is fixedly connected to the other end of the top of the base 1. A shaft seat 7 is fixedly connected to the top of the column 6. A mounting rod 8 is connected to the bearing inside the shaft seat 7. A positioning block 9 is fixedly connected to the outer wall of the mounting rod 8. A hexagonal key shaft 10 is provided in the middle of the mounting rod 8. A movable gear 11 that meshes with the fixed gear 5 is provided on the outside of the hexagonal key shaft 10. A locking nut 12 is threadedly connected to the end of the mounting rod 8.

[0026] The top of the bracket 3 is provided with a limiting mechanism 13. The limiting mechanism 13 includes a limiting frame 131 fixedly connected to the bracket 3. The top of the limiting frame 131 is threadedly connected to an adjusting bolt 132. The bottom of the adjusting bolt 132 passes through the limiting frame 131 and is rotatably connected to a limiting plate 133.

[0027] A platform is provided on the outer wall of the positioning block 9. The platform and the top surface of the bracket 3 are on the same horizontal plane. The bottom surface of the limiting plate 133 is parallel to the top surface of the platform. When the limiting plate 133 is pressed down on the top of the platform, it is convenient to position the mounting rod 8, thereby facilitating the removal of the movable gear 11.

[0028] There are two platforms, and the two platforms do not need to be set in parallel. When designing, it is only necessary to ensure that when the limit plate 133 is pressed on the top of the platform, the fixed gear 5 and the movable gear 11 are in a meshing state.

[0029] In this embodiment, sliding grooves 14 are provided on both sides of the limiting frame 131, and limiting blocks 15 are fixedly connected to both sides of the limiting plate 133. The limiting blocks 15 are slidably connected to the inner wall of the sliding grooves 14, which facilitates limiting the lifting direction of the limiting plate 133.

[0030] In use, the fixed gear 5 rotates in the fixed frame 2. The fixed gear 5 has an adapter 401 on the outside of the central shaft 4 for connecting with the drive shaft of external motors and other equipment to provide driving force.

[0031] The movable gear 11 is mounted on the outside of the mounting rod 8 via a hexagonal key shaft 10. After tightening the locking nut 12 on the outer end of the mounting rod 8, the movable gear 11 is fixed to the mounting rod 8. The movable gear 11 is meshed with the fixed gear 5. When the fixed gear 5 rotates, it drives the movable gear 11 to rotate, which in turn drives the mounting rod 8 to rotate in the bearing 7.

[0032] During disassembly, rotate the movable gear 11 to raise the platform on the outer wall of the positioning block 9. After loosening the nut on the outside of the adjusting bolt 132, rotate the adjusting bolt 132 to drive the limiting plate 133 to descend. Gradually lower the limiting plate 133 to be parallel to the platform. At this time, the positioning block 9 remains stable in angle and posture due to the limitation of the limiting plate 133.

[0033] After unscrewing the locking nut 12, the movable gear 11 can be moved out from the end closest to the locking nut 12. When removing the movable gear 11, the position of the fixed gear 5 is positioned by the self-locking characteristic of the external servo motor drive shaft, so that it remains in the position before the movable gear 11 was removed.

[0034] After maintenance or replacement of the gear, the new movable gear 11 of the same specification can be inserted into the mounting rod 8 along the hexagonal key shaft 10. At the same time, the movable gear 11 gradually re-meshes with the fixed gear 5. This device fixes the shafts of the two gears, keeping the fixed gear 5 and the mounting rod 8 in a fixed position after disassembly. The alignment of the hexagonal key shaft 10 replaces the original meshing between the gear teeth, saving the time of aligning the gears and making disassembly and assembly more convenient and quick. Finally, after tightening the locking nut 12, the limit plate 133 is raised to complete the gear replacement.

[0035] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
