Description

Technical Field

[0001] This utility model relates to a gearbox housing structure that is easy to assemble, and belongs to the field of gearbox technology. Background Technology

[0002] In traditional assembly processes for gearbox housings, the installation of the main body and rear cover often relies on complex positioning and fastening steps. Due to the lack of an effective pre-positioning mechanism, the relative positions between the main body and the rear cover often need to be repeatedly adjusted during assembly to ensure the accuracy of the installation angle. This not only increases the difficulty and time cost of assembly but may also lead to installation errors due to improper operation, affecting the overall performance and reliability of the gearbox.

[0003] Furthermore, traditional assembly methods typically use sealant to enhance the sealing and stability of the connection when connecting the main body of the transmission housing to the rear cover. However, once cured, the sealant often exhibits strong adhesive force, making disassembly difficult when the transmission housing structure needs to be disassembled for maintenance or component replacement. Traditional disassembly methods often require specialized tools or the application of significant external force, which not only increases disassembly costs but may also damage the transmission housing structure, affecting its performance for future use. Utility Model Content

[0004] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a gearbox housing structure that facilitates assembly, achieving precise pre-positioning of the installation angle between the main body of the housing and the rear cover. This simplifies the assembly process and improves assembly accuracy and efficiency.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a gearbox housing structure that is easy to assemble, comprising:

[0006] The outer shell body has a first connecting ring connected to its rear end;

[0007] The rear cover has a second connecting ring that is adapted to the first connecting ring connected to it.

[0008] The second connecting ring has two symmetrically arranged positioning rods on both sides, and the first connecting ring has two symmetrically arranged positioning grooves on both sides.

[0009] When the two positioning rods are inserted into the positioning slots, the installation angle between the outer shell and the back cover is determined.

[0010] Preferably, a partition is fixedly connected inside the positioning groove, and a space for inserting a positioning rod is provided between the partition and the positioning groove.

[0011] Preferably, the partition plate is provided with a threaded hole, and a locking bolt is engaged inside the threaded hole. The threaded end of the locking bolt passes through the side wall of the positioning rod and is engaged with the positioning groove.

[0012] Preferably, a through hole is provided on the side wall of the positioning rod;

[0013] When the positioning rod is inserted into the positioning groove, the through hole aligns with the threaded hole.

[0014] Preferably, the diameter of the through hole is larger than the diameter of the threaded end of the locking bolt.

[0015] Preferably, the positioning groove is provided with an ejection assembly for ejecting the positioning rod out of the positioning groove.

[0016] Preferably, the ejection assembly includes:

[0017] A rotary rod, wherein the rotary rod is disposed inside the positioning groove;

[0018] Top block, which is connected to one end of the rotary rod;

[0019] The connection between the rotary rod and the top block is rotatably connected to the positioning groove;

[0020] When the positioning rod is inserted into the positioning slot, the top block abuts against the end of the positioning rod, and the rotating rod is attached to the side wall of the partition.

[0021] Preferably, the locking bolt is engaged at the end of the rotary rod away from the top block;

[0022] When the slewing rod is attached to the side wall of the partition, the locking bolts engaged on the slewing rod are aligned with the threaded holes.

[0023] Preferably, the positioning rod is fixed to the second connecting ring by a plurality of connecting bolts.

[0024] Preferably, the first connecting ring and the second connecting ring are fixedly connected by a plurality of locking bolts.

[0025] Compared with existing technologies:

[0026] 1. This utility model achieves precise pre-positioning of the installation angle between the outer shell body and the back cover by pre-fixing the positioning rod on the second connecting ring and aligning it with the positioning groove on the first connecting ring. This not only simplifies the assembly process but also greatly improves the accuracy and efficiency of assembly.

[0027] 2. This utility model achieves double locking of the positioning rod and the rotating rod by first screwing the locking bolt onto the rotating rod, and then, after the positioning rod and positioning groove are accurately aligned, by utilizing the cooperation of the top block and the rotating rod, as well as the engagement of the locking bolt with the threaded hole and the side wall of the positioning groove. This ensures a stable connection between the outer shell and the rear cover. This design not only improves the accuracy and reliability of installation but also effectively prevents disassembly difficulties caused by sealant adhesion.

[0028] During disassembly, by unscrewing the locking bolts, which engage only with the rotating rod, and using the protruding part of the locking bolts as a handle, the rotating rod can be easily rotated upwards. This operation not only simplifies the disassembly process but also uses the rotating rod to drive the top block to press against the positioning rod, effectively breaking the adhesive force of the sealant. This allows the outer shell to be easily separated from the back cover, greatly improving the convenience and efficiency of disassembly. Attached Figure Description

[0042] The present invention is illustrated below with specific embodiments, but these are not intended to limit the scope of the invention.

[0043] Example 1

[0044] like Figures 1-6 As shown, in this embodiment, a gearbox housing structure that is easy to assemble is provided, including a housing body 1, and a first connecting ring 101 is connected to the rear end of the housing body 1;

[0045] The rear cover 2 and the outer shell body 1 are connected to a second connecting ring 201 that is adapted to the first connecting ring 101;

[0046] Among them, two positioning rods 3 are symmetrically arranged on both sides of the second connecting ring 201, and two positioning grooves 4 are symmetrically arranged on both sides of the first connecting ring 101.

[0047] When the two positioning rods 3 are inserted into the positioning grooves 4, the installation angle between the outer shell body 1 and the rear cover 2 is positioned.

[0048] The positioning rod 3 is fixed to the second connecting ring 201 by multiple connecting bolts 7.

[0049] The first connecting ring 101 and the second connecting ring 201 are fixedly connected by multiple locking bolts 8.

[0050] Work process:

[0051] When assembling the gearbox housing structure, firstly, align the second connecting ring 201 on the rear cover 2 with the first connecting ring 101 on the outer shell body 1, and pre-fix the positioning rod 3 in the predetermined position of the second connecting ring 201 using the connecting bolt 7. Next, slowly move the rear cover 2 closer to the outer shell body 1, gradually aligning and inserting the positioning rod 3 into the positioning groove 4 on the first connecting ring 101. Once the positioning rod 3 is fully inserted into the positioning groove 4, the installation angle between the outer shell body 1 and the rear cover 2 is accurately positioned. At this point, the first connecting ring 101 and the second connecting ring 201 can be tightly connected together by rotating the locking bolt 8, thus completing the assembly of the gearbox housing structure. The entire assembly process is simple and quick, and the cooperation between the positioning rod and the positioning groove ensures the accuracy of the assembly angle.

[0052] Example 2

[0053] As shown in the figure, in this embodiment, in order to fix the positioning rod 3 inside the positioning groove 4, a partition 401 is fixedly connected inside the positioning groove 4, and a space for inserting the positioning rod 3 is provided between the partition 401 and the positioning groove 4.

[0054] The partition plate 401 is provided with a threaded hole 402, and a locking bolt 5 is engaged inside the threaded hole 402. The threaded end of the locking bolt 5 passes through the side wall of the positioning rod 3 and is engaged with the positioning groove 4.

[0055] A through hole 301 is provided on the side wall of the positioning rod 3. The diameter of the through hole 301 is larger than the diameter of the thread end of the locking bolt 5.

[0056] When the positioning rod 3 is inserted into the positioning groove 4, the through hole 301 is aligned with the threaded hole 402.

[0057] Example 3

[0058] As shown in the figure, based on Embodiment 2, in order to enable the outer shell body 1 and the back cover 2 to be quickly separated, the positioning groove 4 is provided with an ejection assembly 6 for ejecting the positioning rod 3 out of the positioning groove 4. The ejection assembly 6 includes a rotating rod 601 and a top block 602. The rotating rod 601 is disposed inside the positioning groove 4; the top block 602 is connected to one end of the rotating rod 601; wherein, the connection between the rotating rod 601 and the top block 602 is rotatably connected to the positioning groove 4.

[0059] When the positioning rod 3 is inserted into the positioning groove 4, the top block 602 abuts against the end of the positioning rod 3, and the rotating rod 601 is attached to the side wall of the partition 401.

[0060] When disassembling the outer shell body 1 and the rear cover 2, rotate the rotary rod 601 upward. As the rotary rod 601 rotates upward, it also rotates the top block 602. During the rotation, the top block 602 presses against the positioning rod 3, causing the positioning rod 3 to slide out of the positioning groove 4. At this time, the outer shell body 1 and the rear cover 2, which are stuck together by the sealant, can make a separation movement, effectively solving the problem that the sealant sticks the connection between the outer shell body 1 and the rear cover 2 and makes them difficult to separate.

[0061] The locking bolt 5 is engaged with the end of the rotary rod 601 away from the top block 602. When the rotary rod 601 is attached to the side wall of the partition plate 401, the locking bolt 5 engaged with the rotary rod 601 is directly opposite the threaded hole 402.

[0062] During installation, first screw the locking bolt 5 onto the rotating rod 601. When the positioning rod 3 is inserted into the positioning groove 4, that is, after the outer shell 1 and the rear cover 2 are installed in place, the top block 602 abuts against the end of the positioning rod 3, and the rotating rod 601 is attached to the side wall of the partition 401. At this time, screw the locking bolt 5. At this time, the threaded end of the locking bolt 5 engages with the threaded hole 402 and the side wall of the positioning groove 4 in sequence. The locking bolt 5 simultaneously locks the positioning rod 3 and the rotating rod 601 (e.g., Figure 5 (as shown);

[0063] During disassembly, unscrew the locking bolt 5 so that it only engages with the rotating rod 601. At this time, the protruding part of the locking bolt 5 can act as a handle to pull the rotating rod 601 upward. By pulling the locking bolt 5, the rotating rod 601 is driven to rotate upward, causing the rotating rod 601 to rotate with the top block 602. The top block 602 presses against the positioning rod 3, effectively solving the problem that the sealant sticks the connection between the outer shell body 1 and the rear cover 2 and makes it difficult to separate.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate and not limit the technical solutions of this utility model. Although this utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model without departing from the spirit and scope of this utility model. Any modifications or partial substitutions should be covered within the scope of the claims of this utility model.
