[0016] The technical solutions in the embodiments of the present invention will be described in detail below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.
[0017] Refer Figures 1 to 4As shown in the figure, the compact main rolling gearbox in this embodiment includes a box body 1. Rotatably connected inside the box body 1 are an input shaft 2, a first output shaft 3, a second output shaft 4, a third output shaft 5, and a fourth output shaft 6. The input end of the input shaft 2 extends outside the box body 1, and the output ends of the first output shaft 3, the second output shaft 4, the third output shaft 5, and the fourth output shaft 6 all extend outside the box body 1. A first gear 7 and a second gear 8 are fixedly sleeved side by side on the input shaft 2. A third gear 9 and a fourth gear 10 are fixedly sleeved side by side on the first output shaft 3. A fifth gear 11 is fixedly sleeved on the second output shaft 4. A sixth gear 12 and a seventh gear 13 are fixedly sleeved side by side on the third output shaft 5. An eighth gear 14 is fixedly sleeved on the fourth output shaft 6. The first gear 7 is meshed with the third gear 9. The fourth gear 10 is meshed with the fifth gear 11. The second gear 8 is meshed with the sixth gear 12. The seventh gear 13 is meshed with the eighth gear 14.
[0018] Further, the first output shaft 3 and the third output shaft 5 are arranged side by side and symmetrically arranged on both sides of the input shaft 2. The second output shaft 4 and the fourth output shaft 6 are respectively arranged directly above the first output shaft 3 and the third output shaft 5.
[0019] Further, the second output shaft 4 and the fourth output shaft 6 are symmetrically arranged on both sides of the input shaft 2.
[0020] Further, the first gear 7, the second gear 8 and the input shaft 2 are integrally formed.
[0021] In this technical solution, through the way of misaligned meshing of each gear, single input and four outputs are realized in one box body. The overall mechanism is more compact, the cost is reduced, the occupied area is small, and the equipment is lighter.
[0022] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the element.
[0023] The above are only specific implementation manners of the present application. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
