Description

Technical Field

[0001] This utility model relates to the field of gearbox protection, and in particular to a self-reinforced left gearbox housing for a gearbox assembly. Background Technology

[0002] As the "skeleton" of the transmission system, the gearbox housing must withstand gear meshing impacts, torque vibrations, and external loads. Insufficient hardness (e.g., Brinell hardness HB < 150) may cause the housing to deform or even crack, leading to oil leaks or gear misalignment.

[0003] There is a type of gearbox where the housings corresponding to the main gear and the auxiliary gear are spaced apart, thus being independent of each other. This results in low structural strength, making the gearbox prone to deformation during use due to gear meshing impacts, torque vibrations, and external loads.

[0004] In view of this, a solution needs to be proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a self-reinforced left gearbox housing for a gearbox assembly. In use, the main housing and the auxiliary housing are arranged continuously, thus having a certain structural strength. During use, it is not easily deformed due to the impact of gear meshing, torque vibration and external load.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A self-reinforced left housing for a gearbox assembly includes a main housing corresponding to the main gear and a secondary housing corresponding to the secondary gear. The main housing has an opening, and the secondary housing is connected to the opening of the main housing. The main housing has main reinforcing ribs distributed circumferentially, and the secondary housing has secondary reinforcing ribs distributed circumferentially. A connecting rib connects the main housing and the secondary housing.

[0007] Furthermore, the main housing has a three-tiered structure, with a main central ring, a main second-tier ring, and a main third-tier ring distributed from the inside out, and the height of the three-tiered structure decreases sequentially.

[0008] Furthermore, the main housing has a three-tiered structure, with a secondary central platform, a secondary second-tier ring, and a secondary third-tier platform distributed from the inside out, and the secondary third-tier platform is adjacent to the main central ring.

[0009] Furthermore, the sub-center platform is provided with a reinforcing protrusion, which is close to the sub-reinforcing rib.

[0010] Furthermore, a reinforcing platform is provided on the side of the secondary housing facing away from the main housing. The reinforcing platform is located on the secondary third-order platform and is adjacent to the secondary second-order ring.

[0011] Furthermore, the reinforcing platform is provided with supporting ribs distributed circumferentially.

[0012] Furthermore, a reinforcing core is provided on the side of the main housing facing away from the main housing, and the reinforcing core is in contact with the main three-stage ring.

[0013] Compared with existing technologies, this utility model has the following advantages: 1. It mainly improves the structural strength by changing the separation of the housings corresponding to the main gear and the auxiliary gear into a connected main housing corresponding to the main gear and an auxiliary housing corresponding to the auxiliary gear, thereby preventing deformation caused by gear meshing impact and torque vibration. 2. The use of main reinforcing ribs, auxiliary reinforcing ribs, and connecting ribs further strengthens the structural strength between the main housing and the auxiliary housing. 3. The decreasing height of the three-stage structure—main central ring, main second-stage ring, and main third-stage ring—is to reduce weight and accommodate the bearing in the middle. 4. The reinforcing platform and reinforcing core improve the structural strength of the outer sides of the main housing and the auxiliary housing, respectively, thus making them less prone to deformation during use due to gear meshing impact, torque vibration, and external loads.

Detailed Implementation

[0016] The following description is merely a preferred embodiment of this utility model, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of this utility model should be considered within the protection scope of this utility model. It should also be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.

[0017] See Figure 1 and Figure 2 A self-reinforced left housing for a gearbox assembly includes a main housing 1 corresponding to the main gear and a secondary housing 2 corresponding to the secondary gear. The main housing 1 is provided with an opening 3. The opening 3 does not directly separate the two housings, but connects the secondary housing 2 to the opening 3 of the main housing 1, thus forming a connection between the two.

[0018] The main box 1 is surrounded by main reinforcing ribs 4, which are strip-shaped. The main reinforcing ribs 4 can strengthen the structural strength of this part. The secondary box 2 is surrounded by secondary reinforcing ribs 5. The main box 1 and the secondary box 2 are connected by connecting ribs, which can strengthen the connection between the two.

[0019] The main housing 1 has a three-tiered structure, consisting of a main central ring 6, a main second-tier ring 7, and a main third-tier ring 8, distributed from the inside out, with the height decreasing sequentially. Specifically, the main central ring 6 is a cylindrical structure located in the middle of the main housing 1, with the central part used to install bearings. The main second-tier ring 7 is an annular structure distributed outside the main central ring 6, concentric with it, and the main reinforcing rib 4 is used to connect the two, thereby strengthening the structural strength between them. Similarly, the main third-tier ring 8 is an annular structure distributed outside the main second-tier ring 7, concentric with both the main central ring 6 and the main second-tier ring 7, and the outer part of the main reinforcing rib 4 is used to connect the two, thereby strengthening the structural strength between them. This structure improves the overall structural strength of the main housing 1. A reinforcing core 15 is also provided on the side of the main housing 1 facing away from the main housing 1, and the reinforcing core 15 is in contact with the main third-tier ring 8. The height of the three-tiered structure, consisting of the main central ring 6, the main second-tier ring 7, and the main third-tier ring 8, decreases sequentially. This is partly to reduce weight and partly to accommodate the bearings in the middle.

[0020] The secondary housing 2 has a three-tiered structure, consisting of a secondary central platform 9, a secondary second-tier ring 10, and a secondary third-tier platform 11 distributed from the inside out. The secondary third-tier platform 11 is adjacent to the main central ring 6. Specifically, the secondary central platform 9 is a platform-shaped structure, the secondary second-tier ring 10 is a platform-shaped structure located below the secondary central platform 9 and concentric with it, and the secondary third-tier platform 11 is a platform-shaped structure located below the secondary central platform 9 and the secondary second-tier ring 10, which mainly forms the shell shape of this embodiment.

[0021] The secondary central platform 9 is equipped with a reinforcing protrusion 12, which is close to the secondary reinforcing rib 5. A reinforcing platform 13 is also provided on the side of the secondary housing 2 facing away from the main housing 1. The reinforcing platform 13 is located on the secondary third-stage platform 11 and is adjacent to the secondary second-stage ring 10. Supporting ribs 14 are distributed circumferentially on the reinforcing platform 13. The reinforcing platform 13 and the reinforcing core 15 are provided to improve the structural strength of the outer sides of the main housing 1 and the secondary housing 2, respectively, thereby making them less prone to deformation during use due to gear meshing impacts, torque vibrations, and external loads.

[0022] This embodiment primarily improves structural strength by modifying the separation of the housings corresponding to the main gear and the auxiliary gear into a unified structure of the main housing 1 (corresponding to the main gear) and the auxiliary housing 2 (corresponding to the auxiliary gear). This prevents deformation caused by gear meshing impact and torque vibration. Furthermore, the use of main reinforcing ribs 4, auxiliary reinforcing ribs 5, and connecting ribs further strengthens the structural strength between the main housing 1 and the auxiliary housing 2.
