[0002] In the existing metallurgical industry open, winding machine technical field, the connection mode between reduction gearbox and reel usually adopts precision bearing and sealing device to ensure the relative motion and sealing between the two. However, in the actual operation process, due to the complex and changeable working environment, such as high temperature, high pressure, heavy load and other adverse conditions, and the long-time running causes the sealing element of the bearing box both ends to wear and age, the on-site equipment oil return is not beneficial, the lubricating oil is viscous, and the oiling is too much to exceed the oil level display agent phenomenon, the reduction gearbox and reel end sealing lubrication position are prone to oil leakage problems.

[0003] The existing metallurgical industry open, winding machine reduction gearbox and reel connection mode, although perfect in design, but still difficult to completely avoid the leakage of lubricating oil in actual application. Such leakage not only leads to the waste of lubricating oil, increases the operation cost of equipment, but also may have adverse effects on the overall performance and safety of equipment. At the same time, the leaked lubricating oil may also pollute the surrounding environment, which does not conform to the current green and environmentally friendly production concept.

[0027] The present application will be further described below in conjunction with the drawings: Example 1

[0028] The present application provides a kind of steel coil reel machine's reduction gearbox, and the unwinding and winding reduction gearbox thin oil lubrication oil groove, as shown in Figures 1-3 The flow guide groove 3 is communicated with the inside of the reduction gearbox 1, and the depth of the flow guide groove 3 is deeper as it is closer to the reduction gearbox 1, when the lubricating oil leaks from the sealed lubrication position of the reel end, the lubricating oil will flow to the inside of the reduction gearbox 1 along the inclined bottom of the flow guide groove 3, thereby realizing the effect of preventing oil leakage.

[0029] In the specific implementation, according to the leakage amount and flow rate of lubricating oil, the width and depth of the flow guide groove 3 are accurately designed through test, and the optimal size of the flow guide groove 3 is determined according to the equipment requirement, to ensure that it can effectively collect and guide the leaked lubricating oil to flow back to the inside of the reduction gearbox 1, the size of the flow guide groove 3 is preferably 20~30mm in width and about 5mm in depth.

[0030] In addition, as shown in Figure 4 In order to further enhance the sealing effect, a sealing device is arranged between the reduction gearbox 1 and the reel, which includes a sealing end cover 2 designed with existing materials and structures to prevent lubricating oil from leaking out of the gap between the reel end and the reduction gearbox 1, thereby enhancing the oil leakage prevention effect. Example 2

[0031] The basic structure of this embodiment is similar to that of Example 1, but the design of the flow guide groove 3 is different. In this embodiment, the flow guide groove 3 extends along the axial direction of the reel, and its width and depth are also precisely designed according to the amount and flow rate of the leaked lubricating oil. This design allows the flow guide groove 3 to better adapt to the motion trajectory of the reel, thereby more effectively collecting and guiding the leaked lubricating oil back to the inside of the reduction gearbox 1.

[0032] At the same time, this embodiment also uses the same sealing device as Example 1 to ensure the sealing between the reduction gearbox 1 and the reel. Example 3

[0033] This embodiment provides a more complex design of the flow guide groove 3. The difference between this embodiment and Example 2 is that in this embodiment, the flow guide groove 3 is spirally arranged on the inner wall of the rotating hole 4, with the spiral direction extending in the positive rotation direction of the reel. This design allows the flow guide groove 3 to better adapt to the motion trajectory of the reel when the unwinding / reeling machine is positively rotating the reel, and the inertia of the lubricating oil being driven by the rotation of the reel makes it easier for the lubricating oil to flow back to the inside of the reduction gearbox 1.

[0034] In specific implementation, we precisely design the width, depth and spiral angle of the spiral flow guide groove 3 through experiments according to the amount and flow rate of the leaked lubricating oil, to determine the optimal parameters of the spiral flow guide groove 3, so as to ensure that it can effectively collect and guide the leaked lubricating oil back to the inside of the reduction gearbox 1.

[0035] At the same time, this embodiment also uses the same sealing device as Example 1 and Example 2 to ensure the sealing between the reduction gearbox 1 and the reel. Example 4

[0036] The difference between the embodiment and embodiment 2 is that, in the embodiment, the guide groove 3 is spirally arranged on the inner wall of the rotating hole 4, and the spiral direction is extended in the reverse direction of the winding shaft. This design makes the guide groove 3 better adapt to the motion trajectory of the winding shaft when the unwinding and winding machine of the metallurgical industry rotates the winding shaft in the forward direction. The inertia of the lubricating oil driven by the rotation of the winding shaft makes the lubricating oil have a tendency to flow away from the inside of the speed reducer 1. However, the guide groove 3 is open at the end close to the inside of the speed reducer 1, so although it still has a backflow effect, it has a certain oil retention effect compared to embodiment 2, avoiding the problem of insufficient lubricating oil due to too good oil guiding effect, which affects the lubricating effect.

[0037] In specific implementation, we accurately design the width, depth and spiral angle of the spiral guide groove 3 through experiments according to the leakage amount and flow rate of the lubricating oil, and determine the optimal parameters of the spiral guide groove 3 to ensure that it can effectively collect and guide the leaked lubricating oil to flow back to the inside of the speed reducer 1.

[0038] At the same time, the embodiment also adopts the same sealing device as embodiment 1 and embodiment 2 to ensure the sealing between the speed reducer 1 and the winding shaft.

[0039] The above shows and describes the basic principles, main features and advantages of the utility model, and those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model can also have various changes and improvements, and these changes and improvements all fall within the scope of the utility model claimed.
