[0002] Gearboxes, as mechanical transmission devices, are widely used in daily production and life, particularly in applications requiring acceleration and deceleration, changing transmission direction, altering torque, implementing clutch functions, or distributing power. Combined gearboxes, which integrate a reduction gearbox and a distribution box, can be used as the main drive gearbox for rolling mills in bar and wire production lines, as the main drive gearbox for the pinch-feed mechanism in plate and pipe production lines, and in other applications requiring a single-input, multi-output gearbox.

[0003] At present, if two combined gearboxes are required in actual scenarios, the corresponding installation methods are as follows: Figure 1 and Figure 2 As shown, the structure of the corresponding combined gearbox includes a box body 100, an input shaft 200, an intermediate shaft 300, an upper output shaft 400 and a lower output shaft 500. It can be seen that the distance Y between the two output shafts of the two combined gearboxes is the minimum installation distance, which has obvious requirements for the space of the factory and greatly limits the space.

[0024] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments. The present invention is not limited to this embodiment, and other embodiments may also fall within the scope of the present invention as long as they conform to the main purpose of the present invention.

[0025] In a preferred embodiment of the present invention, based on the above problems existing in the prior art, a two-in-one combined gearbox is provided. Figures 3 and 4 As shown, including:

[0026] Box body 1, an input shaft 2 is installed on one side of the box body 1;

[0027] The left intermediate shaft 3 is installed on one side of the housing 1 and is located on the left side of the input shaft 2. The upper left output shaft 4 is installed on the left side of the left intermediate shaft 3, and the lower left output shaft 5 is installed below the upper left output shaft 4.

[0028] The right intermediate shaft 6 is installed on one side of the housing 1 and is located on the right side of the input shaft 2 . The right upper output shaft 7 is installed on the right side of the right intermediate shaft 6 , and the lower right output shaft 8 is installed below the upper right output shaft 7 .

[0029] Specifically, if Figure 3 and Figure 4 As shown, the two-in-one combined gearbox of the present invention includes two combined gearbox mechanisms. One combined gearbox mechanism includes an input shaft 2, a left intermediate shaft 3, an upper left output shaft 4, and a lower left output shaft 5. The other combined gearbox mechanism includes an input shaft 2, a right intermediate shaft 6, an upper right output shaft 7, and a lower right output shaft 8. It can be seen that the two combined gearbox mechanisms share the same input shaft 2 and are symmetrical about it. Furthermore, the input end of the input shaft 2 is located in the center of the housing 1, the output ends of the upper left output shaft 4 and the lower left output shaft 5 are located on the housing 1 on one side of the input shaft 2, and the output ends of the upper right output shaft 7 and the lower right output shaft 8 are located on the housing 1 on the other side of the input shaft 2. Integrating the two independent combined gearboxes into a single two-in-one combined gearbox, with a single motor driving the input shaft 2 and the reducers installed sequentially, effectively saves space and simplifies operation. Furthermore, the two-in-one combined gearbox, with two sets of output shafts on the left and right sides, can simultaneously meet different power output requirements.

[0030] Furthermore, if Figure 3 As shown, it can be seen that the distance X between the two sets of output shafts of the two-in-one combined gearbox of the present invention is the minimum installation distance. Figure 1 It can save about 2 meters of installation space, thereby reducing the footprint of the combined gearbox, effectively utilizing the factory area and reducing the factory cost.

[0031] In a preferred embodiment of the present invention, the input shaft 2 and the left intermediate shaft 3 are connected via a first gear pair, the left intermediate shaft 3 and the upper left output shaft 4 are connected via a second gear pair, and the upper left output shaft 4 and the lower left output shaft 5 are connected via a third gear pair.

[0032] In a preferred embodiment of the present invention, the second gear pair and / or the third gear pair are herringbone gears.

[0033] In a preferred embodiment of the present invention, the input shaft 2 and the right intermediate shaft 6 are connected via a fourth gear pair, the right intermediate shaft 6 and the upper right output shaft 7 are connected via a fifth gear pair, and the upper right output shaft 7 and the lower right output shaft 8 are connected via a sixth gear pair.

[0034] In a preferred embodiment of the present invention, the fifth gear pair and / or the sixth gear pair are herringbone gears.

[0035] Specifically, in this embodiment, by designing the connection method of the gear pairs, the transmission ratio can be flexibly adjusted by adjusting the size and number of teeth of the gear pairs, thereby meeting the needs of different application scenarios. Furthermore, the number and type of gear pairs or the size and shape of the gearbox can be adjusted to flexibly adapt to different application scenarios and needs.

[0036] In a preferred embodiment of the present invention, the left intermediate shaft 3 and the right intermediate shaft 6 , the upper left output shaft 4 and the upper right output shaft 7 , and the lower left output shaft 5 and the lower right output shaft 8 are all symmetrically arranged about the input shaft 2 .

[0037] In a preferred embodiment of the present invention, the axes of the input shaft 2, the left intermediate shaft 3, the upper left output shaft 4, the right intermediate shaft 6 and the upper right output shaft 7 are collinear.

[0038] In a preferred embodiment of the present invention, the axes of the upper left output shaft 4 and the lower left output shaft 5 are collinear, and the axes of the upper right output shaft 7 and the lower right output shaft 8 are collinear.

[0039] The above description is only a preferred embodiment of the present invention and does not limit the implementation method and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the content of this specification and illustrations should be included in the protection scope of the present invention.
