Description

Technical Field

[0001] This utility model relates to the field of gearboxes, specifically to a gearbox with an assembled structure. Background Technology

[0002] Gearboxes have a wide range of applications, such as in wind turbine generators. They are a crucial mechanical component widely used in wind turbine generators. Their main function is to transmit the power generated by the wind turbine under wind force to the generator, enabling it to achieve the corresponding rotational speed.

[0003] A search revealed a utility model of a gearbox with an assembled structure, published under publication number CN215334335U. The gearbox includes a support structure and a sealing structure, wherein the sealing structure is detachably mounted on the support structure. This utility model relates to the field of gearbox technology. The support structure facilitates easy disassembly and assembly of the entire gearbox and allows for the storage and handling of internal engine oil. This makes the installation of the bottom support of the gearbox quicker and easier, and also facilitates disassembly, inspection, and maintenance. The design is simple, convenient, and solves the problem of cumbersome disassembly and maintenance, while also facilitating the handling of accumulated internal engine oil.

[0004] In most existing gearboxes, the low-speed and high-speed shafts are directly placed inside the gearbox housing and then assembled with bolts. However, bolt assembly is not only cumbersome, but also lacks stability for the low-speed and high-speed shafts within the gearbox. In the comparative case above, the prefabricated gearbox structure, although also prefabricated, has its gearbox housing directly assembled. This assembly method lacks a certain degree of sealing, which can easily lead to lubricant leakage, thus affecting the gearbox's performance.

[0005] Therefore, it is necessary to invent a gearbox with an assembly structure to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a gearbox with an assembled structure. By installing the low-speed component and the high-speed component separately in the gearbox housing, and using the first and second limiting brackets on both sides of the bearing placed in the first limiting grooves on both sides inside the gearbox housing, the assembly stability of the low-speed component and the high-speed component is improved. Then, the first locking block under the gearbox cover is inserted into the first locking groove inside the gearbox housing, which not only facilitates the connection between the two but also enhances the sealing. Finally, the two are connected by bolts. This method not only makes the overall gearbox easy to assemble but also improves the assembly stability of the low-speed component and the high-speed component and the sealing between the gearbox housing and the gearbox cover. This solves the problem raised in the comparative case of the assembled structure gearbox in the background art. Although it is also an assembled type, the gearbox housing is directly assembled. This assembly method lacks a certain degree of sealing and is prone to lubricating oil leakage, thus affecting the performance of the gearbox.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a gearbox with an assembled structure, including a housing for assembling gear assemblies;

[0008] A box cover is installed on top of the box cover for assembly. Bolts run through the four sides of the box cover. A first locking block is fixedly installed on the bottom of the box cover. A first locking groove is opened on the upper surface of the box base. Positioning pins are fixedly connected to both sides of the upper part of the box base. A first limiting groove is opened on the inner surfaces of both sides of the box base and the box cover. An oil plug is provided on one side of the box base. A second locking groove is opened on both sides of the box base and the box cover.

[0009] Low-speed and high-speed components are installed inside the housing and are used to drive low-speed and high-speed components.

[0010] A dustproof component is installed on both sides of the box base and the box cover for dust prevention. Limiting mechanisms are fixedly connected to the upper and lower sides of the box base and the box cover.

[0011] Preferably, the first locking block below the box cover is movably engaged with the first locking groove above the box base, and the positioning pin above the box base is movably engaged with the box cover.

[0012] Preferably, an oil inlet is provided on the top of the cover, and an installation groove is provided on the inner surface of the oil inlet. A filter box is installed inside the installation groove, and a filter screen is provided inside the filter box.

[0013] Preferably, the low-speed component includes a low-speed shaft, which is disposed inside the housing. A first limiting frame and a second limiting frame are installed on both sides of the low-speed shaft. Bearings are disposed inside the first limiting frame and the second limiting frame. A gear body is installed on the outside of the low-speed shaft.

[0014] Preferably, the first limiting frame and the second limiting frame are movably engaged in the first limiting grooves on both sides of the housing.

[0015] Preferably, the dustproof component includes a dustproof cover, which is installed on both sides of the housing base and the housing cover. A second locking block is fixedly connected to one side of the dustproof cover, and second limiting grooves are provided on the upper and lower surfaces of the dustproof cover.

[0016] Preferably, the limiting mechanism includes a fixed sleeve, which is installed on the upper and lower sides of the box base and the box cover. A telescopic rod is movably connected inside the fixed sleeve. A connecting plate is fixedly connected to the lower end of the telescopic rod. An insert block is fixedly connected to the lower part of the connecting plate. Springs are provided on the upper sides of the connecting plate and inside the fixed sleeve.

[0017] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0018] The design of the gearbox base, cover, bolts, first locking block, first locking groove, locating pin, first limiting groove, low-speed component, and high-speed component not only facilitates assembly but also enhances the overall gearbox sealing. By installing the low-speed component and high-speed component separately in the gearbox base, and using the first and second limiting brackets on both sides of the bearing placed in the first limiting grooves on both sides inside the gearbox base, the stability of the assembly of the low-speed component and high-speed component is improved. Then, the first locking block under the cover is inserted into the first locking groove inside the upper part of the gearbox base, which not only facilitates the connection between the two but also enhances the sealing. Finally, the two are connected by bolts. This method not only facilitates the assembly of the overall gearbox but also improves the stability of the assembly of the low-speed component and high-speed component and the sealing between the gearbox base and the cover.

[0019] By incorporating dustproof components and limiting mechanisms, when the second limiting bracket and bearing at one end of the low-speed component and high-speed component are exposed outside the gearbox, to prevent dust from entering the interior, the second locking block on one side of the dustproof cover is inserted into the second locking grooves on both sides of the gearbox base and cover. Then, the telescopic rod inside the fixing sleeve on both sides of the gearbox base and cover is pulled, causing the telescopic rod to spring back and insert the locking block into the second limiting grooves on the upper and lower sides of the dustproof cover for limiting and fixing. Compared with the traditional method of directly fixing with threads, this method improves convenience. Attached Figure Description

[0031] This utility model provides, for example Figure 1-7 The gearbox shown has an assembly structure, including a housing 1 for assembling gear assemblies;

[0032] Box cover 2, installed on top of box cover 2 for assembly, bolts 3 pass through the four sides of box cover 2, first locking block 4 is fixedly installed on the bottom of box cover 2, first locking groove 5 is opened on the upper surface of box base 1, positioning pins 6 are fixedly connected on both sides of the upper part of box base 1, first limiting grooves 7 are opened on the inner surfaces of both sides of box base 1 and box cover 2, oil plug 8 is provided on one side of box base 1, and second locking grooves 15 are opened on both sides of box base 1 and box cover 2.

[0033] The low-speed component 13 and the high-speed component 14 are installed inside the housing 1 and are used to drive the low-speed and high-speed components.

[0034] Dustproof components 16 are installed on both sides of the gearbox base 1 and the gearbox cover 2 for dust prevention. Limiting mechanisms 17 are fixedly connected to the upper and lower sides of the gearbox base 1 and the gearbox cover 2. By installing the low-speed component 13 and the high-speed component 14 in the gearbox base 1 respectively, the first limiting bracket 1302 and the second limiting bracket 1303 on both sides of the bearing 1304 are placed in the first limiting groove 7 on both sides inside the gearbox base 1, thereby improving the assembly stability of the low-speed component 13 and the high-speed component 14. Then, the first locking block 4 under the gearbox cover 2 is inserted into the first locking groove 5 inside the upper part of the gearbox base 1, which not only facilitates the docking of the two, but also enhances the sealing. Then, the two are threadedly connected by bolts 3. This method not only makes the overall gearbox easy to assemble, but also improves the assembly stability of the low-speed component 13 and the high-speed component 14 and the sealing between the gearbox base 1 and the gearbox cover 2.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the first locking block 4 below the box cover 2 is movably engaged with the first locking groove 5 above the box base 1, and the positioning pin 6 above the box base 1 is movably engaged with the box cover 2. By aligning the first locking block 4 below the box cover 2 with the first locking groove 5 above the box base 1, not only is the docking between the two improved, but the sealing performance is also improved to a certain extent.

[0036] like Figure 4 As shown, an oil inlet 9 is provided on the top of the cover 2. An installation groove 10 is provided on the inner surface of the oil inlet 9. A filter box 11 is installed inside the installation groove 10. A filter screen 12 is provided inside the filter box 11. When lubricating oil is injected into the oil inlet 9, impurities in the lubricating oil are prevented from causing wear on internal parts or affecting normal use. The lubricating oil is filtered by the filter screen 12 inside the filter box 11 installed inside the oil inlet 9.

[0037] like Figure 1 , Figure 2 and Figure 5 As shown, the low-speed component 13 includes a low-speed shaft 1301, which is disposed inside the housing 1.

By installing the first limiting frame 1302 and the second limiting frame 1303 on the low-speed component 13 and the high-speed component 14 respectively, the low-speed component 13 and the high-speed component 14 can be conveniently limited and installed in the housing 1.

[0038] like Figure 2 , Figure 3and Figure 5 As shown, the first limiting frame 1302 and the second limiting frame 1303 are respectively movably engaged in the first limiting grooves 7 on both sides of the housing 1. By using the first limiting frame 1302 and the second limiting frame 1303 to be engaged in the first limiting grooves 7 on both sides of the housing 1, the stability of the assembly of the low-speed component 13 and the high-speed component 14 can be improved.

[0039] like Figure 1 and Figure 6 As shown, the dustproof assembly 16 includes a dustproof cover 1601, which is installed on both sides of the housing 1 and the housing cover 2. A second locking block 1602 is fixedly connected to one side of the dustproof cover 1601. Second limiting grooves 1603 are provided on the upper and lower surfaces of the dustproof cover 1601. The second locking block 1602 on one side of the dustproof cover 1601 is inserted into the second locking grooves 15 provided on both sides of the housing 1 and the housing cover 2 to enhance the dustproof performance of the housing 1 and the housing cover 2 and prevent dust from entering the bearing 1304 and affecting the normal rotation of the low-speed assembly 13 and the high-speed assembly 14.

[0040] like Figure 6 and Figure 7 As shown, the limiting mechanism 17 includes a fixing sleeve 1701, which is installed on the upper and lower sides of the box base 1 and the box cover 2. A telescopic rod 1702 is movably connected inside the fixing sleeve 1701. A connecting plate 1703 is fixedly connected to the lower end of the telescopic rod 1702. An insert block 1704 is fixedly connected to the lower part of the connecting plate 1703. Springs 1705 are provided on the upper sides of the connecting plate 1703 and inside the fixing sleeve 1701. By pulling the telescopic rod 1702 inside the fixing sleeve 1701 on both sides of the box base 1 and the box cover 2, after the dust cover 1601 is installed on both sides of the box base 1 and the box cover 2, the telescopic rod 1702 is released, so that the telescopic rod 1702 rebounds through the spring 1705 and inserts the insert block 1704 into the second limiting groove 1603 on the upper and lower sides of the dust cover 1601 for limiting and fixing. Compared with the traditional direct fixing by threads, the convenience is improved.

[0041] The working principle of this utility model is as follows: First, the low-speed component 13 and the high-speed component 14 are assembled in the housing 1. The first limiting bracket 1302 and the second limiting bracket 1303 on both sides are placed in the first limiting grooves 7 on both sides of the housing 1 to improve the stability of the assembly of the low-speed component 13 and the high-speed component 14. Then, the first locking block 4 under the housing cover 2 is inserted into the first locking groove 5 inside the upper part of the housing 1, which not only facilitates the connection between the two but also enhances the sealing. Then, the two are threaded together by bolts 3. Next, the telescopic rod 1702 inside the fixing sleeve 1701 on both sides of the housing 1 and the housing cover 2 is pulled, which drives the connecting plate 1703 and the insert block 1704 below the telescopic rod 1702 to extend and retract. Then, the second locking block 1602 on one side of the dust cover 1601 is inserted into the second locking block on one side of the housing 1 and the housing cover 2. In slot 15, the telescopic rod 1702 is then released. The springs 1705 on both sides above the connecting plate 1703 push the insert 1704 below the connecting plate 1703 into the second limiting groove 1603 on both sides of the dust cover 1601, thus limiting and fixing the dust cover 1601. Then, the dust cover 1601 is installed on the exposed position of the high-speed component 14 on the other side of the gearbox 1 and the gearbox cover 2 through the same steps. In this way, the entire gearbox is assembled. When lubricating oil needs to be injected, it is injected from the oil inlet 9 above the gearbox cover 2. The oil inlet 9 is equipped with a filter box 11, which can filter the lubricating oil and prevent some particles from entering the inner wall of the gearbox 1 and causing certain wear. In this way, the use of the gearbox with the assembled structure is completed.
