Description

Technical Field

[0001] The utility model mainly relates to the technical field of metallurgical steel rolling equipment, in particular to a lubrication structure of a low-speed reducer. Background Art

[0002] In the metallurgical industry, the lubrication method for reducers on steel rolling equipment lines and nonferrous equipment lines is generally thin oil lubrication, and the lubricating oil often has the risk of leakage.

[0003] At present, there are two types of reducer lubrication methods. One is forced lubrication by a thin oil station, and the other is lubrication by splashing a certain amount of thin oil stored inside the gear box itself.

[0004] The inventor discovered the following defects during the operation of the specific embodiment:

[0005] The splash lubrication of the gearbox is closely related to the amount of oil stored inside. If the amount of oil stored is higher than the input shaft system, the oil seal is mainly used to ensure that the seal does not leak oil. The oil seal is also a rubber product that is vulnerable to wear. This will lead to the leakage of lubricating oil and cause secondary pollution. After the lubricating oil leaks, the gears and bearings of the gearbox will not be well lubricated, and eventually the reducer cannot be used normally, causing huge losses to actual production.

[0006] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Utility Model Content

[0026] See attached Figure 1-2A lubrication structure of a low-speed reducer comprises a reducer housing 1, wherein a plurality of input shaft bearings 2 are installed inside the reducer housing 1, the input shaft bearings 2 are rotatably connected to the inside of the reducer housing 1, a working gear 4 is installed outside the input shaft bearings 2, and the plurality of working gears 4 are meshed and transmitted with each other, wherein an oil-slinging idler wheel 3 is rotatably connected below two working gears 4 on the right side, the oil-slinging idler wheel 3 is meshed and transmitted with the working gear 4 on the left side, and a lubricating oil storage level gauge 5 is installed below the working gear 4 and the oil-slinging idler wheel 3, and when the oil-slinging idler wheel 3 and the working gear 4 rotate, the lubricating oil is splashed onto other working gears 4, ensuring the meshing between the working gears 4 and the lubrication of the input shaft bearings 2 themselves, thereby avoiding leakage of the gearbox lubricating oil and causing secondary pollution to the environment.

[0027] In this embodiment, five working gears 4 are provided, and four working gears 4 are horizontally installed inside the reducer housing 1 , and one working gear 4 is meshed with the lower parts of two of the working gears 4 for transmission.

[0028] It should be noted that the transmission between the multiple working gears 4 is realized, and the lubricating oil is splashed onto other working gears 4 during the transmission process to maintain the meshing effect between the multiple working gears 4.

[0029] In this embodiment, a sealed box door 6 is detachably mounted on the top of the reducer housing 1 by means of a plurality of bolts, and a handle 7 is symmetrically connected to the top surface of the sealed box door 6 .

[0030] It should be noted that by removing a plurality of bolts and removing the sealed box door 6 from the top of the reducer housing 1 using the handle 7 , the lubricating oil can be introduced to the position of the lubricating oil storage level gauge 5 .

[0031] In this embodiment, a heat dissipation pipe 8 is connected to the middle of the top surface of the sealed box door 6 , the bottom of the heat dissipation pipe 8 is connected to the interior of the reducer housing 1 , and a breathable cap 9 is installed on the top of the heat dissipation pipe 8 .

[0033] The working principle of the utility model is as follows: the rotation of multiple input shaft system bearings 2 is driven by power, so that multiple working gears 4 are meshed with each other and transmit to each other. When the rotation speed becomes lower and lower, the lubricating oil is splashed onto the multiple working gears 4 above under the action of the lower working gear 4 and the oil-slinging idler wheel 3, so that the lubrication between the working gear 4 and the input shaft system bearings 2 is maintained, and the meshing transmission between the multiple working gears 4 is ensured. By splashing the lubricating oil, the leakage of the gear box lubricating oil is avoided, which causes secondary pollution to the environment.
