Description
Technical Field
The utility model relates to a planetary reducer, in particular to a liquid cooling planetary reducer.
Background
The existing liquid cooling planetary reducer mainly comprises a reduction gearbox, a main reducer body structure, a liquid cooling mechanism and an output flange, wherein the main reducer body structure and the liquid cooling mechanism are arranged inside the reduction gearbox, lubricating oil used for lubricating the main reducer body structure is stored inside the reduction gearbox, so that the service life of each part in the main reducer body structure is guaranteed, the liquid cooling mechanism is used for cooling the lubricating oil, the lubricating effect is reduced due to the fact that the temperature of the lubricating oil is too high, the output flange is arranged at the tail end of the reduction gearbox, and the inner side face of the output flange is in contact with the lubricating oil.
The existing liquid cooling mechanism mainly comprises a cooling pipe, wherein the cooling pipe is arranged in a reduction gearbox along the axial direction of the reduction gearbox and is soaked in lubricating oil. When the lubricating oil is cooled, the cooling liquid is filled into the cooling pipe, and the larger the contact area between the lubricating oil and the cooling pipe is, the better the cooling effect is.
In order to increase the contact area between the lubricating oil and the cooling pipes, the cooling effect of the lubricating oil is ensured, or the number of the cooling pipes is increased, or the length of the cooling pipes is increased. However, the internal size of the reduction gearbox is increased, so that the overall size of the liquid cooling planetary reducer is increased, and the structure is not compact enough.
Disclosure of Invention
The utility model aims to solve the technical problem of providing the liquid cooling planetary reducer which has the advantages of ensuring the cooling effect on lubricating oil, along with smaller overall size and high structural compactness.
The technical scheme adopted for solving the technical problems is as follows: the utility model provides a liquid cooling planetary reducer, includes reducing gear box, reducing gear box body structure, liquid cooling mechanism and output flange, reducing gear box body structure with liquid cooling mechanism all set up the reducing gear box inside, the reducing gear box inside store lubricating oil, output flange install the terminal of reducing gear box, output flange's medial surface with lubricating oil contact, liquid cooling mechanism including soak the fin heating panel in lubricating oil and set up the annular channel that is in the outside sunken on the output flange inside wall, the fin heating panel with annular channel seal, output flange on be provided with the communicating liquid cooling import of annular channel and liquid cooling export.
The fin heat dissipation plate is fixed on the output flange through a plurality of bolts, and the fin heat dissipation plate and the output flange are sealed.
Compared with the prior art, the lubricating oil cooling device has the advantages that the fin cooling plate immersed in lubricating oil and the annular channel which is formed on the inner side wall of the output flange and is recessed outwards are arranged, the annular channel is sealed by the fin cooling plate, a sealed flow channel is formed between the fin cooling plate and the annular channel, when the lubricating oil is cooled, heat in the lubricating oil is transferred to a cooling liquid position in the sealed flow channel through the fin cooling plate and is taken away by the cooling liquid, because the fin cooling plate has larger surface area in a smaller space, the contact area between the lubricating oil and the fin cooling plate is larger, the reduction gearbox size does not need to be increased additionally, and even the reduction gearbox size can be reduced, so that the lubricating oil cooling effect is ensured, meanwhile, the whole size is smaller, and the structure compactness is high.

Detailed Description
The utility model is described in further detail below with reference to the embodiments of the drawings.
Embodiment one: as shown in fig. 1, a liquid cooling planetary reducer comprises a reduction gearbox 1, a main reducer body structure 2, a liquid cooling mechanism and an output flange 3, wherein the main reducer body structure 2 and the liquid cooling mechanism are arranged inside the reduction gearbox 1, lubricating oil is stored inside the reduction gearbox 1, the output flange 3 is arranged at the tail end of the reduction gearbox 1, the inner side surface of the output flange 3 is in contact with the lubricating oil, the liquid cooling mechanism comprises a fin 4 immersed in the lubricating oil and an annular groove 5 formed in the inner side wall of the output flange 3 and recessed outwards, the fin 4 seals the annular groove 5, and a liquid cooling inlet 6 and a liquid cooling outlet 7 which are communicated with the annular groove 5 are arranged on the output flange 3.
When the liquid cooling planetary reducer of the embodiment is used, the reducer main body structure 2 is connected with a driving source (namely a driving motor) and is connected with a load through the output flange 3, the liquid cooling inlet 6 is connected with cooling liquid through a pipeline, and the liquid cooling outlet 7 is connected with a liquid discharge pipe. The driving source works to transmit power to the position of the main body structure 2 of the speed reducer, and the main body structure 2 of the speed reducer converts the power transmitted to the position and outputs the converted power to the load to drive the load to work. In the process, cooling liquid continuously flows into the annular groove 5 through the liquid cooling inlet 6 to be in contact with the fin cooling plate 4, heat of lubricating oil transferred to the fin cooling plate 4 is taken away, and cooling of the lubricating oil is achieved. Because the fin cooling plate 4 has a larger surface area in a smaller space, and the fin cooling plate 4 is completely soaked in the lubricating oil, the contact area between the fin cooling plate 4 and the lubricating oil is also large, and thus the cooling effect of the lubricating oil can be ensured.
Embodiment two: this embodiment is substantially the same as embodiment one, except that: in this embodiment, the fin heat dissipation plate 4 is fixed to the output flange 3 by a plurality of bolts 8, and is sealed therebetween. By sealing the fin heat sink 4 and the output flange 3, lubrication oil can be prevented from entering the annular channel 5.
