Description

Technical Field

[0001] This utility model relates to a split-type gearbox housing structure, belonging to the field of gearbox technology. Background Technology

[0002] The housing structure of a transmission is typically designed as a single unit, which presents numerous inconveniences in manufacturing and maintenance. A single housing structure not only makes maintenance and replacement of internal transmission components difficult, but it can also deform or crack after bearing heavy loads or prolonged operation, leading to reduced stability and reliability of the transmission. Furthermore, securing the bearing housings is often a complex and cumbersome process, relying on numerous fasteners and intricate assembly techniques to ensure their stability within the housing. Traditional fixing methods not only increase installation costs and time, but can also cause the bearing housings to wobble or shift during operation due to loose fasteners or improper assembly, thus affecting the overall performance and durability of the transmission. Utility Model Content

[0039] The present invention is illustrated below with specific embodiments, but these are not intended to limit the scope of the invention.

[0040] Example 1

[0041] like Figures 1-8As shown in the figure, this embodiment provides a split gearbox housing structure, including a first housing 1, a second housing 2, and a bearing seat 3. The first housing 1 is provided with a first flange 101 at its end, the second housing 2 is provided with a second flange 201 at its end, and the bearing seat 3 is provided with a connecting ring 301 on its side. The first flange 101 and the second flange 201 are provided with multiple threaded holes, and the first flange 101 and the second flange 201 are fixed by bolts through the threaded holes. The first housing 1 and the second housing 2 are connected by the first flange 101 and the second flange 201. The connecting ring 301 is clamped at the connection between the first housing 1 and the second housing 2, thereby fixing the bearing seat 3.

[0042] Both the first shell 1 and the second shell 2 have multiple circumferentially distributed protruding ribs 8 on their outer walls.

[0043] The bearing housing 3 has a bearing support hole 303 at its center.

[0044] During the assembly of the gearbox, firstly, the first housing 1 and the second housing 2 are prepared, ensuring that the transmission components inside each are correctly installed. Then, the bearing housing 3 is placed in the predetermined position, so that the connecting ring 301 on its side can be clamped at the connection between the first housing 1 and the second housing 2. Next, the first flange 101 and the second flange 201 are aligned, and bolts are screwed in one by one through the threaded holes until the two flanges are tightly fitted, thus fixing the bearing housing 3 at the connection between the first housing 1 and the second housing 2. At this point, the assembly of the gearbox's split housing structure is complete. During gearbox operation, the first housing 1 and the second housing 2 jointly support the internal transmission components, and the tight connection ensures the stability and reliability of the gearbox. Simultaneously, the bearing housing 3 supports the bearings inside the gearbox, ensuring the smooth operation of the shafts and the normal operation of the gearbox.

[0045] Example 2

[0046] like Figures 1-8 As shown, based on Embodiment 1, in order to stably fix the bearing seat 3 inside the first housing 1 and the second housing 2, a fixing ring 4 is provided at the end of the first housing 1 near the first flange 101 and the end of the second housing 2 near the second flange 201. A pressure groove 401 for clamping the connecting ring 301 is provided on the opposite sidewall of the two fixing rings 4.

[0047] Multiple positioning protrusions 402 are evenly distributed inside the pressure groove 401, and multiple positioning grooves 302 are evenly distributed on the side wall of the connecting ring 301.

[0048] When the connecting ring 301 is pressed into the inside of the pressure groove 401, the positioning protrusion 402 is inserted into the inside of the positioning groove 302.

[0049] The first housing 1, near the first flange 101, and the second housing 2, near the second flange 201, are both provided with mounting grooves 5 for mounting the fixing ring 4.

[0050] The fixing ring 4 is fixedly installed inside the mounting groove 5 by multiple bolts. The bolts are countersunk bolts. The positioning protrusion 402 on the fixing ring 4 has a countersunk bolt hole. The mounting groove 5 has a threaded hole corresponding to the countersunk bolt hole. After the countersunk bolt is inserted into the countersunk bolt hole, its threaded end is tightened in the threaded hole, thereby fixing the fixing ring 4 inside the mounting groove 5.

[0051] First, a retaining ring 4 is installed at one end of each housing near the flange, and the retaining ring 4 is fixed inside the mounting groove 5 using countersunk bolts. Then, the connecting ring 301 is pressed into the groove 401 of the retaining ring 4, ensuring that the positioning protrusion 402 and the positioning groove 302 are correctly inserted, thereby achieving stable fixation of the bearing seat 3 inside the first housing 1 and the second housing 2.

[0052] Example 3

[0053] like Figures 1-7 As shown, based on the above embodiments, in order to stably fix the bearing seat 3 inside the first housing 1 and the second housing 2, multiple inner protruding ribs 6 are circumferentially distributed on the inner walls of the first housing 1 and the second housing 2.

[0054] When the bearing housing 3 is installed inside the first housing 1 and the second housing 2, the ends of the inner convex ribs 6 on the first housing 1 and the ends of the inner convex ribs 6 on the second housing 2 respectively abut against the two side walls of the bearing housing 3.

[0055] Multiple support blocks 7 are circumferentially distributed on both sides of the bearing housing 3. The multiple support blocks 7 are fixed by bolts, and the outer walls of the multiple support blocks 7 are provided with abutment grooves 701.

[0056] When the bearing housing 3 is installed inside the first housing 1 and the second housing 2, multiple support blocks 7 are pressed against the corresponding inner convex ribs 6 through the abutment grooves 701.

[0057] The support block 7 is fixedly connected to the side wall of the bearing housing 3 by bolts. Then, the bearing housing 3 together with the support block 7 is placed between the first housing 1 and the second housing 2. At this time, the ends of the inner protruding ribs 6 on the first housing 1 and the second housing 2 respectively abut against the two side walls of the bearing housing 3, and the abutting groove 701 of the support block 7 is in close contact with the inner protruding ribs 6, forming a stable fixing structure.

[0058] Thus, the bearing housing 3 is stably fixed inside the gearbox housing through the tight fit between the support block 7 and the inner protruding rib 6, as well as the clamping action of the first housing 1 and the second housing 2. This improves the fixing stability of the bearing housing 3 and enhances the overall performance of the gearbox.

[0059] 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.
