Technical Field

[0001] This utility model relates to the field of speed reducer housing technology, specifically a speed reducer reinforced housing. Background Technology

[0002] The gearbox housing is an important component of the gearbox. Its main function is to protect the internal transmission parts and mechanisms and provide a good heat dissipation environment. Gearbox housings are usually made of high-strength materials, such as cast iron or aluminum alloy, to ensure their durability and stability.

[0003] Patent CN218863222U discloses a speed reducer housing, including a housing with an inner shell fixed inside. Reinforcing plates are fixed to the surface of the housing, a protective reinforcement mechanism is provided inside the housing, a clamping mechanism is provided inside the inner shell, and a stabilizing mechanism is provided at the bottom of the housing. This invention not only prevents the housing from tipping over during use, increasing the overall strength of the inner shell and significantly enhancing its load-bearing capacity, but also prevents the machine from shaking during use.

[0004] The above-mentioned device has certain shortcomings in its use: the reducer housing is mainly used to protect the internal transmission parts and structure, including the bottom mounting ears, which are also part of the housing. The reducer is mainly installed on the base or fixed frame and fixed with bolts and nuts to improve the installation strength of the entire reducer housing. However, the positions of the openings on some bases or fixed frames and the positions of the holes on the reducer housing mounting ears may not be completely compatible, so there is a problem of insufficient stability strength during installation.

[0005] Therefore, this utility model provides a speed reducer reinforced housing to solve the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a speed reducer reinforced housing, which solves the aforementioned problems.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a speed reducer reinforced housing, including a housing base, a housing assembly installed on the top of the housing base, and adjustment and fixing assemblies fixedly installed on the front and rear parts of the top wall of the housing base;

[0008] The adjusting and fixing assembly includes two abutting friction rings, which are symmetrically arranged front and back. The bottom walls of both abutting friction rings are fixedly connected to the top wall of the housing base. Sliding grooves are provided on the front and back parts of the top wall of the housing base, corresponding to the positions of the abutting friction rings. Limiting grooves are provided on the front and back walls of both sliding grooves. Several sliding blocks are slidably installed on the inner walls of both sliding grooves. Limiting sliders are fixedly installed on the front and back walls of the sliding blocks. The outer walls of the limiting sliders are slidably connected to the inner walls of the corresponding limiting grooves. Fastening bolts are screwed onto the top walls of the sliding blocks.

[0009] By adjusting the settings of the fixing components, when the entire device needs to be installed on the base or mounting bracket, the position of the fastening bolts can be adjusted according to the position of the holes on the mounting bracket, thereby improving the adaptability of the installation.

[0010] Furthermore, the bottom walls of several fastening bolts and nuts are all fixed in contact with the top walls of the corresponding abutting friction rings, and gaskets are fitted onto the outer walls of several fastening bolts.

[0011] The above technical solution completes the installation and fixation after the fastening bolts come into contact with the friction ring.

[0012] Furthermore, the housing assembly includes a high-strength housing, the bottom wall of which is fixedly connected to the top wall of the housing base, and limit frames are fixedly installed on both the inner wall of the high-strength housing and the top wall of the housing base. Limit slides are slidably installed on the inner walls of several limit frames, and the same protective cover is fixedly installed on the adjacent side of several limit slides. A speed reducer component is installed inside the housing assembly, and the inner wall of the protective cover is fixedly connected to the speed reducer component.

[0013] The high-strength housing, as described above, is primarily used for protective covers and speed reducer components.

[0014] Furthermore, the top wall of the protective cover is evenly provided with several heat dissipation holes, and the top wall of the high-strength shell is provided with heat dissipation grooves at the positions corresponding to the heat dissipation holes.

[0015] The above technical solution uses heat dissipation holes and heat dissipation slots primarily to dissipate heat from the gearbox components during operation.

[0016] Furthermore, the right side wall of the high-strength shell is evenly provided with positioning grooves, and positioning blocks are movably installed on the inner wall of several positioning grooves. The adjacent side of several positioning blocks is fixedly connected to the outer wall of the protective cover.

[0017] Through the above technical solution, the positioning block and positioning groove work together to locate the installation position of the protective cover.

[0018] Furthermore, hexagonal holes are provided at the four corners of the right side wall of the protective cover, and hexagonal seats are slidably installed on the inner walls of several hexagonal holes, and the same mounting cover is fixedly installed on the right side wall of several hexagonal seats.

[0019] Through the above technical solution, the hexagonal hole and hexagonal base cooperate with each other, and the hexagonal base can be driven by the mounting cover to abut and fix the protective cover.

[0020] Furthermore, the mounting cover is fitted onto the right side of the outer wall of the high-strength shell, and the four corners of the right side wall of the mounting cover are screwed onto the right side wall of the high-strength shell using mounting bolts.

[0021] Using the above technical solution, the mounting cover is screwed onto the right side wall of the high-strength shell using mounting bolts.

The top wall of the shell base 4 is provided with sliding grooves 31 at the front and rear parts and corresponding to the positions of the abutting friction rings 32. The front and rear walls of the two sliding grooves 31 are provided with limiting grooves 34. Several sliding blocks 36 are slidably installed on the inner walls of the two sliding grooves 31. Limiting sliders 37 are fixedly installed on the front and rear walls of the several sliding blocks 36. The outer walls of the several limiting sliders 37 are slidably connected to the inner walls of the corresponding limiting grooves 34. Fastening bolts 35 are screwed onto the top walls of the several sliding blocks 36. The bottom walls of the nuts of the several fastening bolts 35 are abutted and fixed to the top walls of the corresponding abutting friction rings 32. Washers 33 are sleeved onto the outer walls of the several fastening bolts 35.

[0037] In this embodiment of the utility model, the purpose of this arrangement is to adjust the setting of the fixing component 3. When the reducer component 2 needs to be installed, the housing base 4 needs to be placed on the top of the fixing frame, and then the fastening bolt 35 is screwed into the corresponding screw hole on the top of the fixing frame. When the screw hole position does not match the fastening bolt 35, the sliding fastening bolt 35 drives the sliding block 36 to slide in the inner wall of the sliding groove 31, and the sliding block 36 slides in the inner wall of the corresponding limiting sliding groove 34. The position of the fastening bolt 35 can be adjusted to the corresponding screw hole on the top of the fixing frame, which expands the installation adaptability of the entire device and can prevent the problem of mismatch between the screw hole position and the fastening bolt 35 position.

[0038] Example 2:

[0039] Please see Figure 1-6 This embodiment provides a technical solution based on Embodiment 1: the housing assembly 1 includes a high-strength housing 11, the bottom wall of the high-strength housing 11 is fixedly connected to the top wall of the housing base 4, limit frames 13 are fixedly installed on both the inner wall of the high-strength housing 11 and the top wall of the housing base 4, limit slides 14 are slidably installed on the inner walls of several limit frames 13, and the same protective cover 15 is fixedly installed on the adjacent side of several limit slides 14. The inner wall of the protective cover 15 is fixedly connected to the reducer component 2, and several heat dissipation holes 18 are evenly opened on the top wall of the protective cover 15. The top wall of the high-strength housing 11 is also provided with corresponding heat dissipation holes 18. The high-strength shell 11 has a heat dissipation groove 16. The right side wall of the high-strength shell 11 is evenly provided with positioning grooves 17. Positioning blocks 19 are movably installed on the inner wall of several positioning grooves 17. The adjacent side of several positioning blocks 19 is fixedly connected to the outer wall of the protective cover 15. Hexagonal holes 110 are provided at the four corners of the right side wall of the protective cover 15. Hexagonal seats 111 are slidably installed on the inner wall of several hexagonal holes 110. The same mounting cover 12 is fixedly installed on the right side wall of several hexagonal seats 111. The mounting cover 12 is sleeved and installed on the right side of the outer wall of the high-strength shell 11. The four corners of the right side wall of the mounting cover 12 are screwed onto the right side wall of the high-strength shell 11 by mounting bolts.

[0040] In this embodiment of the utility model, the purpose of this arrangement is that the housing component 1 can quickly fix the protective cover 15 on which the reducer component 2 is installed into the interior of the high-strength housing 11. The installation method is relatively simple, and after installation, it has good working stability and heat dissipation effect.

[0041] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0042] During operation, the protective cover 15 of the fixed reducer component 2 is installed inside the high-strength housing 11. The movable protective cover 15 drives the limiting slide 14 into the corresponding limiting frame 13. At the same time, the positioning block 19 is placed into the inner wall of the corresponding positioning groove 17 for limiting and fixing. The movable mounting cover 12 is sleeved and installed on the right outer wall of the high-strength housing 11. The mounting cover 12 drives the hexagonal seat 111 into the corresponding hexagonal hole 110 for abutment and fixing. It is then screwed onto the right side wall of the high-strength housing 11 with mounting bolts, thus completing the overall installation and fixing of the reducer component 2 and the protective cover 15. When the reducer component 2 is working, the heat generated can be dissipated through the heat dissipation holes 18 and heat dissipation grooves 16. When heat needs to be dissipated, it can be dissipated through the housing assembly 1 and the bottom of the housing. With the cooperation of the four seats, the entire device is installed on the fixed frame. When the screw hole position on the mounting frame does not match the fastening bolt 35, the sliding fastening bolt 35 drives the sliding block 36 to slide in the inner wall of the corresponding sliding groove 31. When the sliding block 36 slides, it drives the limiting slider 37 to slide in the inner wall of the corresponding limiting groove 34. After the fastening bolt 35 slides to the position corresponding to the screw hole on the fixed frame, the fastening bolt 35 is screwed into the corresponding screw hole by rotating the tool and fixed, so that the fastening bolt 35 is greater than the top wall of the abutting friction ring 32 and fixed. At the same time, the gasket 33 is located between the shell base 4 and the fixed frame for support and fixation, so that the fastening bolt 35 can complete the installation and fixation of the shell base 4 and the entire device.
