All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-4, in the embodiment of the present invention, the reducer includes a reducer body 1, a water cooling mechanism 2, an oil circulation mechanism 3, and a cooling water jacket 4, an accommodating cavity 11 is formed between a housing of the reducer body 1 and a tubular bearing seat at the center, a partition plate 12 is disposed inside the accommodating cavity 11 to form a circulation water cavity 111 and a circulation oil cavity 112, the circulation oil cavity 112 is located at an input end of the reducer body 1, the water cooling mechanism 2 includes a first water inlet 21, a first water outlet 22, and a spiral plate 23 disposed between the first water inlet 21 and the first water outlet 22, the water cooling mechanism 2 is disposed inside the circulation water cavity 111, the first water inlet 21 and the first water outlet 22 are communicated with an outside of the reducer body 1, the oil circulation mechanism 3 includes a plurality of oil inlet cylinders 31 uniformly arranged around the tubular bearing seat of the reducer body 1 in the circumferential direction, the plurality of oil inlet cylinders 31 all penetrate through all spiral surfaces of the spiral plate 23 and communicate an internal box body of the reducer body 1 with the circulation oil cavity 112, the cooling water jacket 4 is sleeved on a periphery of an output end of the reducer body 1, and the cooling water jacket 4 is communicated with an inside of the circulation water cavity 111.
The accommodating cavity 11 is a closed accommodating cavity formed by the whole set of cooling system by means of the structure of the accommodating cavity, and has no additional external communication port except for a plurality of water inlets and water outlets, so that static sealing treatment is not required to be carried out by using a sealing ring. The surface of the partition plate 12 is provided with a plurality of mounting holes for assembling the oil inlet cylinder 31, and the oil inlet cylinder 31 penetrates through the spiral plate 23 and then communicates the circulating oil cavity 112 with the internal box body of the speed reducer body 1 for circulating lubricating oil. When the oil inlet cylinder 31 is installed, the side wall of the oil inlet cylinder 31 is spaced from the inner wall of the circulating water chamber 111 by a certain distance so that the cooling liquid is sufficiently in contact with the oil inlet cylinder 31. After entering the circulating water chamber 111 from the first water inlet 21, the cooling liquid passes through all the spiral flow paths formed by the spiral plates 23 and is finally discharged from the first water outlet 22. When the lubricating oil enters the circulating oil cavity 112 through the oil inlet cylinder 31, the highest point of the lubricating oil is 1/3-2/3 of the circulating oil cavity 112, and the oil inlet cylinder 31 at the upper part enables the pressure balance between the circulating oil cavity 112 and the internal box body of the speed reducer body 1 to be kept, so that the dynamic circulating backflow of the lubricating oil is ensured.
The oil circulation mechanism 3 further includes an oil outlet 32, and the oil outlet 32 communicates the circulation oil chamber 112 with the outside of the speed reducer body 1. When the speed reducer normally works, the oil outlet 32 is closed, the lubricating oil participates in normal circulation, and if the lubricating oil needs to be replaced, the lubricating oil can be directly discharged through the oil outlet 32.
Referring to fig. 3, the spiral plate 23 includes N spiral surfaces, N is greater than or equal to 2, and the spiral plate 23 needs to have a certain number of spiral surfaces to ensure a sufficiently long spiral flow path for the cooling fluid to flow through, so as to increase the contact time between the cooling fluid and the oil inlet cylinder 31, and make the dynamic heat exchange between the cooling fluid and the oil inlet cylinder 31 more sufficient.
Referring to fig. 1 and fig. 2, the water cooling mechanism 2 further includes a second water outlet 24, and the second water outlet 24 is disposed at one end of the circulating water cavity 111 close to the first water outlet 22 and is opposite to the first water outlet 22. The second water outlet 24 may be disposed at the terminal end of the spiral flow path, further than the first water outlet 22. The second water outlet 24 is communicated with the second water inlet 41 of the cooling water jacket 4, so that the cooling water jacket 4 and the water cooling mechanism 2 share one set of cooling system, the cooling liquid conveying flow is reduced, and the structure is simplified.
In order to complete the whole circulation of the cooling water jacket 4, the cooling water jacket 4 further includes a third water outlet 42 and a water outlet 43, the second water inlet 41 and the third water outlet 42 are respectively disposed on the side walls of the two ends of the cooling water jacket 4, so that the path between the third water outlet 42 and the first water outlet 22 is shortest, the path between the second water outlet 24 and the second water inlet 41 is shortest, and the path of the circulation of the cooling liquid is shortened.

In addition, the cooling water jacket 4 further comprises a hose assembly 44, and the second water inlet 41 is communicated with the second water outlet 24 through the hose assembly 44, so that when the cooling water jacket 4 is installed at a certain deviation in position and angle with the speed reducer body 1, the second water inlet 41 can still be normally assembled with the second water outlet 24.
Referring to fig. 4, the cooling water jacket 4 is in interference fit with the gear ring of the reducer body 1, so as to enhance the firmness of connection. The inner diameter of the cooling water jacket 4 is slightly larger than the outer diameter of the water box shell 13 of the reducer body 1, and the output end of the reducer body 1 is connected with the shield machine and is not convenient to detach, so that the cooling water jacket 4 can be conveniently taken out from the direction of the input end of the reducer body 1 when needing to be replaced through the arrangement.
In order to ensure the strength of the cooling water jacket 4, the main body of the cooling water jacket 4 is formed by welding steel plates, but the heat conductivity of the steel plates is low, so that the heat exchange is not facilitated. Therefore, the copper plate 45 is arranged on the side, in contact with the gear ring of the reducer body 1, of the cooling water jacket 4, the copper plate 45 is welded with the steel plate main body of the cooling water jacket 4, the thickness of the copper plate 45 is smaller than that of the surrounding steel plates, the copper plate 45 has high ductility and heat conductivity, interference connection between the cooling water jacket 4 and the reducer body 1 is facilitated, heat exchange between cooling liquid and the reducer body 1 is enhanced, the steel plate is arranged on the outer main body of the cooling water jacket 4, the steel plate has high strength, and the service life of the cooling water jacket 4 is prolonged.
