Description

Technical Field

[0001] This utility model relates to the field of internal rotor motor technology, specifically to a shock-absorbing through-shaft internal rotor speed reducer that is easy to install. Background Technology

[0002] Through-shaft internal rotor reducers are power devices that integrate internal rotor motors and reduction mechanisms into one unit and use a through-shaft main shaft as the core transmission and support component. They are widely used in electric vehicles, industrial automation, precision machinery and other fields. However, existing through-shaft internal rotor reducers have the problem of not being able to reduce vibration during use.

[0003] If a speed reduction device is subjected to overload or instantaneous impact load for a long time, it may cause plastic deformation of gears and shafts, disrupting the original damping balance. Vibration will accelerate the fatigue wear of components such as gears and bearings, which may lead to serious failures such as broken teeth and shaft breakage. Summary of the Invention

[0004] The purpose of this invention is to provide an easy-to-install shock-absorbing through-shaft internal rotor speed reducer to solve the problem mentioned in the background art that current speed reducers on the market cannot provide shock absorption.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shock-absorbing through-shaft internal rotor reduction device that is easy to install, comprising a housing, a cover provided on one side of the housing, a rotor body provided inside the housing, a planetary gear set provided on the rotor body, a flange ring provided on the outer surface of the housing, support frames provided at the top and bottom of the flange ring, sliders slidably connected to both ends of the two support frames, a first damper provided between one end of each of the four sliders and the interior of the two support frames, a support assembly for supporting the housing provided on the sliders, an installation assembly for installing the cover on the housing, and a shock-absorbing assembly for damping the planetary gear set inside the housing.

[0006] Preferably, the support assembly includes four connecting rods rotatably connected to one end of the four sliders, and the other ends of the two upper connecting rods and the two lower connecting rods are all connected to mounting plates.

[0007] Preferably, the mounting assembly includes four spline sleeves respectively disposed around one side of the housing, and spline shafts are disposed around one side of the housing cover, with the four spline shafts slidably connected inside the four spline sleeves respectively.

[0008] Preferably, threaded sleeves are provided around one side of the housing, and four threaded sleeves are slidably connected to the inside of the housing cover. Each of the four threaded sleeves is threaded with a locking screw, and the diameter of the locking screw head is larger than the diameter of the threaded sleeve.

[0009] Preferably, the shock-absorbing component includes a rotating ring rotatably connected inside the housing, with hexagonal sleeves arranged around one side of the rotating ring, and hexagonal prisms slidably connected inside each of the four hexagonal sleeves.

[0010] Preferably, each of the four hexagonal prisms is provided with a second damper at its other end, and the other end of each of the four second dampers is connected to a turntable, with one side of the turntable connected to the rotor body.

[0011] Preferably, both ends of the two mounting plates are provided with mounting holes, and the two mounting holes are arranged symmetrically.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The housing can be supported by the support components. When vibration occurs, the slider will slide inside the support frame, and then the first damper will apply resistance to it, which can achieve the effect of damping in the vertical direction. It can quickly dissipate the impact energy, reduce the peak impact force, and prevent the impact from being transmitted through the housing to the inside, causing damage to the inside of the housing.

[0013] The installation components allow for quick installation of the cover, improving installation efficiency. They also facilitate disassembly and inspection of the interior of the cover, enabling quick opening of the cover to expose internal components and shortening maintenance time.

[0014] By setting up vibration damping components, the effect of damping the rotor body inside the housing is achieved. Vibration can cause the rotor core to loosen, the permanent magnet to fall off, or the winding insulation layer to be damaged by repeated friction, resulting in a short circuit. The vibration damping components can also suppress the vibration amplitude of the core and protect the structural integrity of the winding and permanent magnet. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides the following technical solution: a shock-absorbing through-shaft internal rotor reduction device that is easy to install. Example 1: To address the problem of existing through-shaft internal rotor reduction devices failing to provide vibration damping during use, the following is disclosed: a housing 1, a cover 2 on one side of the housing 1, a rotor body 3 inside the housing 1, a planetary gear set 4 on the rotor body 3, and a flange ring 5 on the outer surface of the housing 1 (e.g., Figure 1 and Figure 4 As shown), support frames 6 are provided at the top and bottom of flange ring 5. Sliding sliders are slidably connected to both ends of the two support frames 6. A first damper 7 (as shown) is provided between one end of each of the four sliders and the interior of the two support frames 6. Figures 1-3 As shown), the slider is provided with a support assembly to support the housing 1. Inside the housing 1, there is a damping assembly to dampen the planetary gear set 4. The support assembly includes four connecting rods 8 rotatably connected to one end of the four sliders, which are used to support the housing 1. The other ends of the two upper connecting rods 8 and the two lower connecting rods 8 are all connected to mounting plates 9. The damping assembly includes a rotating ring 13 rotatably connected inside the housing 1. Hexagonal sleeves 14 (such as...) are provided around one side of the rotating ring 13. Figure 5 As shown), each of the four hexagonal sleeves 14 has a hexagonal prism 15 slidably connected inside. Each of the four hexagonal prisms 15 has a second damper 16 at one end. Each of the four second dampers 16 has a turntable 17 at one end, and one side of the turntable 17 is connected to the rotor body 3. Both ends of the two mounting plates 9 have mounting holes, and the two mounting holes are symmetrically arranged (e.g., ...). Figures 1-3 As shown, it is used to install housing 1.

[0019] When it is necessary to install the housing 1, it can then be quickly installed through the mounting holes on the two mounting plates 9 (e.g. Figures 1-3As shown), this provides vertical support for the housing 1. When the equipment is subjected to a vertical impact, the housing 1 displaces vertically due to inertia, which drives the connecting rod 8 through the flange ring 5. Subsequently, the connecting rod 8 pushes the slider inside the support frame 6 to slide horizontally. The slider compresses the first dampers 7 at both ends, and then the first dampers 7 dissipate the vibration energy (such as...). Figures 1-3 As shown), this reduces the vertical vibration amplitude of the housing 1, preventing the impact from being directly transmitted to the internal components. When the housing 1 is subjected to vibration from both sides, the turntable 17 will squeeze the second damper 16, and then the second damper 16 will dampen the vibration (as shown). Figure 5 As shown), when the rotor body 3 needs to be disassembled for maintenance, the second damper 16 and the hexagonal prism 15 can be driven away from the hexagonal sleeve 14 by the turntable 17.

[0020] Example 2: Unlike Example 1, the installation assembly can be used to install the cover 2. It is disclosed that: the housing 1 is provided with an installation assembly for installing the cover 2, and the installation assembly includes four spline sleeves 10 respectively disposed around one side of the housing 1 (e.g., Figure 1 , Figure 4 and Figure 6 As shown), splined shafts 11 are provided around one side of the cover 2, and the four splined shafts 11 are slidably connected to the inside of the four splined sleeves 10. Threaded sleeves 12 are also provided around one side of the cover 1, and the four threaded sleeves 12 are slidably connected to the inside of the cover 2. Each of the four threaded sleeves 12 has a locking screw threaded into it (e.g., ...). Figures 1-4 As shown), and the diameter of the locking screw head is greater than the diameter of the threaded sleeve 12.

[0021] When it is necessary to install the cover 2, the splined shaft 11 can be aligned with the splined sleeve 10, and then the cover 2 can be attached to the housing 1. Then, the four splined shafts 11 are respectively inserted into the four splined sleeves 10 (e.g., Figure 1 , Figure 4 and Figure 6 As shown), the spline can slide axially to fit, and the toothed mesh can restrict the rotational freedom of the cover 2 relative to the housing 1. When the spline shaft 11 is inserted into the spline sleeve 10, the threaded sleeve 12 will enter the periphery of the cover 2. Then, the locking screw is turned into the threaded sleeve 12 (as shown). Figures 1-4 As shown in the figure, since the diameter of the locking screw head is larger than the diameter of the threaded sleeve 12, the sliding of the threaded sleeve 12 can be restricted, thereby completing the installation of the cover 2.

[0022] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.
