[0041] It should be noted that like reference numerals and letters denote like items in the following figures, and thus, once an item is defined in one figure, further definition and explanation thereof is not required in subsequent figures.

[0042] The following describes in detail some embodiments of the present invention in conjunction with the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0043] Reference Figures 1 to 3 , at least one embodiment provides a transmission speed reducer device applicable to a heavy-duty industrial environment, including: a speed reduction mechanism 1, which includes a first gear 11, a second gear 12, a third gear 13, and a connecting component 14. The first gear 11, the second gear 12, and the third gear 13 are sequentially meshed together to change the input high speed and low torque into the output low speed and high torque. The connecting component 14 is adapted to push the second gear 12 away from the first gear 11 and the third gear 13 when the speed reduction mechanism 1 jams, and is used to separate the three when the first gear 11, the second gear 12, and the third gear 13 are meshed and the force is too large, avoiding damage to the first gear 11, the second gear 12, and the third gear 13, and being beneficial to improving the service life of the speed reducer; a power generation mechanism 2, which meshes with the speed reduction mechanism 1 to generate electric energy; a support mechanism 3, which is electrically connected to the power generation mechanism 2 and is used to control the support mechanism 3 to separate from the speed reduction mechanism 1 when the speed reduction mechanism 1 jams, that is, after the speed reduction mechanism 1 jams, the support mechanism 3 stops supporting the speed reduction mechanism 1, so that the gears on the speed reduction mechanism 1 are separated and no longer continue to mesh, thereby achieving the purpose of protecting the gears; the support mechanism 3 is connected to the oil pressure system of the external control system and is used to supply oil pressure to the support mechanism 3 before the speed reducer is used to make it provide a supporting force for the speed reduction mechanism 1.

[0044] In some embodiments, the horizontally placed second gear 12 meshes with the vertically placed first gear 11 and third gear 13 on both sides. The second gear 12 is movably connected to the connecting circular shaft on the first gear 11 or the third gear 13 through a connecting component 14 to form a structure for reducing speed and increasing torque. The support mechanism 3 is adapted to support the second gear 12 and generate a supporting force for it.

[0045] In some embodiments, the connecting component 14 is inserted into the connecting hole in the middle of the second gear 12. The support mechanism 3 includes an oil cylinder 31, a support disk 32, and a switch 33. The push rod of the oil cylinder 31 is connected to the support disk 32. The support disk 32 is adapted to support the second gear 12 and generate a supporting force for it. The switch 33 is connected to the oil cylinder 31 through a pipeline to control the pressure of the oil cylinder 31.

[0046] In some embodiments, the connecting component 14 includes a sleeve 15, a connecting shaft 16, and a tensioning member 17. One end of the connecting shaft 16 is connected to the sleeve 15, and the other end is inserted into the connecting hole of the second gear 12. The sleeve 15 is sleeved on the end of the connecting circular shaft of the first gear 11 or the second gear 12. One end of the tensioning member 17 is connected to the second gear 12, and the other end is connected to the sleeve 15 to provide a pulling force for the second gear 12 to keep it meshed with the first gear 11 and the third gear 13. When the force among the three is too large, it ensures that the first gear 11 and the third gear 13 drive the second gear 12 to separate from them to avoid damage to the three.

[0047] In some embodiments, the tensioning member 17 is located outside the connecting shaft 16. The connecting shaft 16 is rotatably connected to both the sleeve 15 and the second gear 12.

[0048] In some embodiments, the tensioning member 17 is a spring. Circular retaining disks are provided at both ends of the connecting shaft 16 to prevent the connecting shaft 16 from separating from the sleeve 15 and the second gear 12.

[0049] In some embodiments, the power generation mechanism 2 includes a driven gear 21 and a generator 22. One end of the driven gear 21 meshes with the first gear 11 or the third gear 13, and at the same time, the other end is connected to the rotating shaft of the generator 22 through a coupling to ensure that the generator 22 can generate electricity driven by the driven gear 21. The generator 22 is electrically connected to the switch 33 to control the opening and closing of the switch 33.

[0050] In some embodiments, the generator 22 is a DC generator. The switch 33 is an electromagnetic switch for easy control. When the generator 22 supplies power to the switch 33, the switch 33 closes, and the oil cylinder 31 maintains the supporting force.

[0051] In some embodiments, the power generation mechanism 2 is arranged above the connecting component 14 through a connecting plate; the supporting mechanism 3 is arranged on the base below the second gear 12 to provide a position for its installation.

[0052] Working principle: Before starting to use a transmission reduction gear device applicable to a heavy-duty industrial environment, an external control system provides hydraulic oil with a certain pressure to the oil cylinder 31, so that the supporting mechanism 3 provides sufficient supporting force to the second gear 12. Then the switch 33 remains closed, and the hydraulic oil system of the external control system reduces the hydraulic oil pressure so that when the switch 33 is closed, it can accept high-pressure oil; at the same time, the input shaft of the reduction mechanism is connected to the power mechanism, and the output shaft is connected to the transmission mechanism; When starting to use a transmission reduction gear device applicable to a heavy-duty industrial environment: the power mechanism works to drive the reduction mechanism 1 to work. During this process, the first gear 11, the second gear 12, and the third gear 13 of the reduction mechanism 1 are engaged in sequence. When the engagement of the first gear 11, the second gear 12, and the third gear 13 is too large, that is, the actuator connected to the transmission mechanism cannot drive the heavy object to move, which is also called jamming; the reduction mechanism 1 cannot drive the driven gear 21 to rotate, so it cannot drive the generator 22 to work, thus causing the switch to open, and the high-pressure oil in the oil cylinder 31 returns to the external control system through the switch 33, that is, only when the external control system detects that the reduction gear is in normal use and the switch 33 is de-energized, the high-pressure oil in the oil cylinder 31 returns to the external control system; at the same time, the first gear 11 or the third gear 13 drives the second gear 12 to separate from the first gear 11 and the third gear 13, and at the same time stretches the tension member 17 and pulls the connecting shaft 16 to move; at this time, the reduction gear stops working. After a short period of time, the external control system provides high-pressure oil to the oil cylinder 31 again, and then the oil cylinder pushes the second gear 12 to reset; repeat the above process until the work is completed.
