Description

Technical Field

[0001] This utility model relates to the technical field of front housing of reducers, and in particular to an integrated front housing of a main reducer. Background Technology

[0002] The front housing of a reducer plays a crucial role in mechanical transmission systems, and its design and the choice of manufacturing materials significantly impact the efficiency and lifespan of the entire transmission system. Traditionally, the front housing of a reducer is designed separately from the main housing. This means that after other components are installed inside the main housing, the front housing is then installed onto the main housing to achieve a seal. This separate structural design makes it susceptible to environmental factors during actual disassembly and assembly. For example, limited installation space results in insufficient distance between the reducer end face and other components, making it difficult to remove the front housing due to insufficient "depth." The same applies to installation; users cannot fully observe the situation and cannot align the front housing with the main housing, reducing the efficiency of reducer disassembly, assembly, and use.

[0003] To address the aforementioned problems, this utility model provides improvements. Summary of the Invention

[0004] This utility model proposes an integrated front housing for a main reducer, which solves the above-mentioned problems existing in the use of the prior art.

[0005] The technical solution of this utility model is implemented as follows: An integrated main reducer front housing includes a main reducer housing. A guide rail is integrally formed and fixedly connected to the top of the main reducer housing. A main reducer front housing is inserted into the interior of the main reducer housing. A sliding hole with equal spacing is opened on one side of the inner cavity of the guide rail. A positioning pin is slidably installed in the inner cavity of the sliding hole. A spring is fixedly connected to one end of the positioning pin. A sealing block is threadedly installed on one side of the inner cavity of the sliding hole. One end of the spring abuts against the sealing block. A sliding block that slides in the guide rail is fixedly connected to one side of the main reducer front housing. A positioning hole with equal spacing and adapted to the positioning pin is opened on one side of the sliding block.

[0006] The present invention, as described above, is used for the front housing of an integrated main reducer. Further, grooves are provided on both sides of the sliding block, and multiple rollers are rotatably installed in the inner cavity of the grooves, with the rollers rolling close to the inner wall of the guide rail.

[0007] The present invention, as described above, is used for the front housing of an integrated main reducer. Further, the bottom of the front housing of the reducer is provided with a notch, and the bottom of the inner cavity of the main housing of the reducer is fixedly connected with a support block adapted to the notch. The top of the support block is provided with a slot, and the slot is on the same axis as the main housing of the reducer.

[0008] The present invention, as described above, is used for the front housing of an integrated main reducer. Further, mounting ears are fixedly connected to both sides of the front housing of the reducer, and mounting ear grooves adapted to the mounting ears are opened at both ends of one side of the main housing of the reducer.

[0009] The present invention, as described above, is used for the front housing of an integrated main reducer. Further, a uniformly distributed fastening bolt is provided through one side of the main housing of the reducer, and a uniformly distributed bolt hole adapted to the fastening bolt is provided on one side of the main housing of the reducer. The front housing of the reducer and the mounting lug are fixedly installed on the main housing of the reducer by the fastening bolt.

[0010] The present invention, as described above, is used for the front housing of an integrated main reducer. Further, a sealing ring mounting groove 1 is provided on one side of the main housing of the reducer, and a sealing ring mounting groove 2, which is adapted to the sealing ring mounting groove 1, is provided on one side of the inner cavity of the main housing of the reducer.

[0011] The present invention, as described above, is used for the front housing of an integrated main reducer. Further, a transmission rod is inserted into the inner cavity of the main housing of the reducer, and the transmission rod is inserted into a notch and a slot.

[0012] In summary, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model adopts an integrated structure design with added guide rails. The front housing can unfold upward along the guide rail on the main housing without separating and exposing the opening of the main housing, so as to facilitate the disassembly of parts. The front housing can be quickly aligned with the main housing by moving it down along the guide rail, so as to quickly complete the assembly of the reducer, improve the assembly efficiency of the reducer, and provide convenience for users' work and use.

[0014] 2. This utility model uses a groove and a roller. The groove is formed on the sliding block and the roller is installed in the groove.

[0027] The following will refer to the appendix in the embodiments of this utility model. Figure 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0028] An integrated main reducer front housing includes a reducer main housing 1. A guide rail 4 is integrally formed and fixedly connected to the top of the reducer main housing 1. A reducer front housing 3 is inserted into the interior of the reducer main housing 1. A sliding hole 5 with equal spacing is opened on one side of the inner cavity of the guide rail 4. A positioning pin 6 is slidably installed in the inner cavity of the sliding hole 5. A spring 7 is fixedly connected to one end of the positioning pin 6. A sealing block 8 is threadedly installed on one side of the inner cavity of the sliding hole 5. One end of the spring 7 abuts against the sealing block 8. A sliding block 9 that slides in the guide rail 4 is fixedly connected to one side of the reducer front housing 3. A positioning hole 10 with equal spacing and adapted to the positioning pin 6 is opened on one side of the sliding block 9.

[0029] The specific usage process is as follows: Structurally, the front housing 3 of the reducer can be moved and unfolded on the main housing 1 of the reducer. At the same time, it is designed to be difficult to separate from the main housing 1. This satisfies the integrated structural design and allows the front housing 3 to unfold on the main housing 1, thus facilitating the user's disassembly and assembly of internal parts of the reducer. It is not affected by external factors or limited by space, improving the flexibility of reducer disassembly and assembly. Therefore, an integrated structural design with guide rails is adopted. The front housing can unfold upwards on the main housing along the guide rails without separating and exposing the opening of the main housing, facilitating parts disassembly. Moving the front housing downwards along the guide rails allows it to be quickly aligned with the main housing for rapid... To complete the assembly of the reducer, improve assembly efficiency, and provide convenience for users, it should be noted that in order to ensure the reducer's sealing performance, sealing structures, such as sealing rings, should be installed at various gaps during actual use. During operation, first remove all fastening bolts 17, then slide the reducer front housing 3 outwards towards the outside of the reducer main housing 1. This article describes the upward movement of the reducer front housing 3. The reducer front housing 3 separates from the support block 2 and also moves away from the inner cavity of the reducer main housing 1. The support block 2 serves to limit the position of the reducer front housing 3 and also supports the transmission rod 21, ensuring the balance of the transmission rod 21 after installation and ensuring normal and smooth power transmission. The notch 13 is used to... The support block 2 is adapted to ensure that the front housing 3 of the reducer can be precisely aligned with the main housing 1 of the reducer, providing convenience for the user's installation. Then, the front housing 3 of the reducer will drive the sliding block 9 to slide inside the guide rail 4. When the sliding block 9 moves, it will first compress the positioning pin 6 and enter the inner cavity of the sliding hole 5. Under the action of the sealing block 8, the positioning pin 6 will also compress the spring 7, so that the current positioning pin 6 will move out of the current positioning hole 10. Then, as the sliding block 9 continues to move, under the action of the spring 7, the positioning pin 6 will be engaged in the next positioning hole 10, and then move out of the current positioning hole 10 again. This process is repeated until the front housing 3 of the reducer is fully opened and the opening of the main housing 1 of the reducer is fully exposed. At this time, the corresponding positioning pin 6 The mounting lug 15 will engage with the positioning hole 10 at its current position, temporarily positioning the front housing 3 of the reducer. This prevents the front housing 3 from moving freely and avoids hindering the user's ability to disassemble and assemble internal parts, facilitating the user's work. The groove 11 is formed on the sliding block 9, and the roller 12 is installed within the groove 11. When the sliding block 9 slides within the guide rail 4, the roller 12 rolls close to the inner wall of the guide rail 4, reducing friction between the sliding block 9 and the inner wall of the guide rail 4, improving the smoothness of the opening and closing of the front housing 3 of the reducer, and providing convenience for the user's work. During installation, after the front housing 3 of the reducer is aligned with the main housing 1 of the reducer, the mounting ear 15 will also engage with the mounting ear groove 16.This design effectively limits the installation of the reducer front housing 3 and aligns the holes on the mounting ears 15 with the bolt holes 18, facilitating the installation and tightening of the bolts 17. This streamlines the assembly process. After all components are disassembled and assembled, pressing down on the reducer front housing 3 causes the sliding block 9 to slide within the guide rail 4. All the locating pins 6 repeatedly move in and out of their corresponding locating holes 10 until the reducer front housing 3 is fully engaged within the reducer main housing 1, and all the locating pins 6 are engaged in their corresponding locating holes 10. Simultaneously, the mounting ears 15 engage in their mounting ear grooves 16, aligning the holes on the reducer front housing 3 and mounting ears 15 with all the bolt holes 18. Finally, the bolts 17 are inserted and tightened to secure the reducer, completing the disassembly and maintenance of the reducer. To improve the efficiency of disassembly and maintenance and provide convenience for users, the sealing ring mounting groove 19 and sealing ring mounting groove 20 are both used to install sealing rings. This ensures the sealing performance of the reducer after the front housing 3 is installed and closed onto the main housing 1, preventing oil leakage and ensuring normal operation. The fastening bolt 17 is used to fix the front housing 3 to the main housing 1. During installation, the fastening bolt 17 is passed through the holes on the front housing 3 and the mounting lug 15, and simultaneously inserted into the corresponding bolt hole 18. Finally, it is tightened to ensure the firmness of the front housing 3 after installation, guaranteeing the normal operation of the reducer and providing convenience for users.

[0030] The sliding block 9 has grooves 11 on both sides, and multiple rollers 12 are rotatably installed in the inner cavity of the grooves 11. The rollers 12 roll close to the inner wall of the guide rail 4.

[0031] Specifically, the groove 11 and roller 12 are designed such that the groove 11 is formed on the sliding block 9, and the roller 12 is installed in the groove 11. When the sliding block 9 slides in the guide rail 4, the roller 12 rolls close to the inner wall of the guide rail 4. This reduces the friction between the sliding block 9 and the inner wall of the guide rail 4, improves the smoothness of the opening and closing of the front housing 3 of the reducer, and provides convenience for the user's work.

[0032] The bottom of the front housing 3 of the reducer is provided with a notch 13. The bottom of the inner cavity of the main housing 1 of the reducer is fixedly connected with a support block 2 that is adapted to the notch 13. The top of the support block 2 is provided with a slot 14. The slot 14 and the main housing 1 of the reducer are on the same axis.

[0033] Specifically, the support block 2, notch 13, and slot 14 are designed to limit the position of the front housing 3 of the reducer and support the transmission rod 21, ensuring the balance of the transmission rod 21 after installation and ensuring the normal and smooth transmission of power. The notch 13 is designed to fit the support block 2, ensuring that the front housing 3 of the reducer can be precisely connected with the main housing 1 of the reducer, providing convenience for the user's installation work.

[0034] Both sides of the front housing 3 of the reducer are fixedly connected with mounting ears 15, and both ends of one side of the main housing 1 of the reducer are provided with mounting ear grooves 16 that are adapted to the mounting ears 15.

[0035] Specifically, the mounting ears 15 and mounting ear slots 16 are designed so that after the front housing 3 of the reducer is fitted and aligned with the main housing 1 of the reducer during installation, the mounting ears 15 will also be inserted into the mounting ear slots 16. This can limit the installation of the front housing 3 of the reducer and also make the holes on the mounting ears 15 aligned with the bolt holes 18, making it convenient for users to install and tighten the bolts 17, thus providing convenience for the user's assembly work.

[0036] One side of the main housing 1 of the reducer is provided with uniformly distributed fastening bolts 17, and one side of the main housing 1 of the reducer is provided with uniformly distributed bolt holes 18 that are adapted to the fastening bolts 17. The front housing 3 of the reducer and the mounting ears 15 are fixedly installed on the main housing 1 of the reducer by fastening bolts 17.

[0037] Specifically, the fastening bolts 17 and bolt holes 18 are designed to secure the front housing 3 of the reducer to the main housing 1 of the reducer. During installation, the fastening bolts 17 are passed through the holes on the front housing 3 and the mounting ears 15 of the reducer, and simultaneously inserted into the corresponding bolt holes 18. Finally, they are tightened to secure the reducer, ensuring the stability of the front housing 3 after installation, ensuring the normal operation of the reducer, and providing convenience for the user's work.

[0038] A sealing ring mounting groove 19 is provided on one side of the main housing 1 of the reducer, and a sealing ring mounting groove 20 that matches the sealing ring mounting groove 19 is provided on one side of the inner cavity of the main housing 1 of the reducer.

[0039] Specifically, the sealing ring mounting groove 19 and the sealing ring mounting groove 20 are both used to install sealing rings. In this way, after the front housing 3 of the reducer is installed and closed onto the main housing 1 of the reducer, the sealing performance of the reducer can be guaranteed, and oil leakage and seepage of the reducer can be avoided, ensuring the normal operation of the reducer and providing convenience for the user.

[0040] A transmission rod 21 is inserted into the inner cavity of the main housing 1 of the reducer, and the transmission rod 21 is inserted into the notch 13 and the slot 14.

[0041] Specifically, the transmission rod 21 is the drive shaft of the reducer. One end of the transmission rod 21 is used to receive power, while the other end transmits the power, thereby ensuring the normal operation of the reducer and providing convenience for the user's work.
