Description

Technical Field

[0001] This utility model relates to the field of papermaking equipment technology, specifically to a bearing oil spraying structure and a high-temperature silkening machine that can improve lubrication performance. Background Technology

[0002] The paper industry is an important basic raw material industry, and the high-temperature fiberizing machine is a commonly used piece of equipment in the paper industry. The high-temperature fiberizing machine operates at high speed and under heavy load. Due to the high pressure in the grinding chamber, the bearings also need to withstand a large axial load. Therefore, most high-temperature fiberizing machines use spherical roller thrust bearings.

[0003] Due to the operating conditions of high-temperature silk-forming machines, bearings require a good, stable, and reliable lubrication environment. Conventional bearing lubrication cannot achieve relatively uniform lubrication, or when uniform lubrication is achieved, it cannot meet the bearing's cooling requirements, or it requires a large amount of lubricating oil, which cannot meet the increasingly demanding requirements of high-temperature silk-forming machines. Utility Model Content

[0004] The purpose of this invention is to provide a bearing oil spraying structure and a high-temperature silkening machine that can improve lubrication performance, thereby solving the aforementioned problems of bearings used in current high-temperature silkening machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bearing oil injection structure that improves lubrication performance includes a bearing housing, a bearing, a bearing sleeve, and a spindle. The bearing includes an inner ring and an outer ring. The outer ring is mounted on the bearing housing, and the inner ring is mounted on the bearing sleeve. An oil injection ring is disposed in the bearing housing, and an oil slinger sleeve is fitted on the spindle. The side wall of the oil injection ring is circumferentially provided with an oil reservoir, and the end face of the oil injection ring corresponding to the bearing is circumferentially provided with multiple oil injection holes, each of which communicates with the oil reservoir. The oil slinger sleeve is disposed inside the oil injection ring, and the oil injection holes are used to spray lubricating oil onto the outer wall of the oil slinger sleeve. The rotation of the spindle drives the oil slinger sleeve to rotate, thereby slinging lubricating oil onto the bearing.

[0007] Furthermore, the oil injection hole is inclined towards the axis of the oil injection ring to spray lubricating oil onto the outer wall of the oil slinger sleeve.

[0008] Furthermore, the outer wall of the oil-throwing sleeve is recessed to form an arc-shaped groove for throwing out lubricating oil.

[0009] Furthermore, one end of the oil-slinging sleeve abuts against the inner ring, and the other end is provided with a locking nut, which is sleeved on the main shaft to press the oil-slinging sleeve.

[0010] Furthermore, a first sealing groove is provided on the side wall of the fuel injection ring, the first sealing groove is located on one side of the oil reservoir, and a second sealing groove is provided on the end face of the fuel injection ring away from the fuel injection hole.

[0011] Furthermore, the bearing housing has multiple circular holes circumferentially, and the oil injection ring has multiple threaded holes correspondingly.

[0012] Furthermore, the threaded hole is located inside the first sealing groove.

[0013] The beneficial effects of this utility model are:

[0014] This invention relates to a bearing oil spraying structure that improves lubrication performance. An oil spraying ring is installed in the bearing chamber, and an oil slinger is fitted onto the main shaft. The side wall of the oil spraying ring has a circumferentially oriented oil reservoir, and the end face of the oil spraying ring corresponding to the bearing has multiple circumferentially oriented oil spray holes, each connected to the oil reservoir. The oil slinger is located inside the oil spraying ring. In actual use, after lubricating oil is injected into the oil reservoir, the lubricating oil is output through the oil spray holes, thus spraying lubricating oil onto the outer wall of the oil slinger. The rotation of the main shaft drives the oil slinger to rotate at high speed, and the lubricating oil evenly sprayed onto the outer wall of the oil slinger is quickly flung out, thereby evenly distributing the lubricating oil onto the bearing, achieving both lubrication and cooling effects.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] The bearing oil spraying structure in this embodiment of the invention, which improves lubrication performance, is achieved by adding an oil spraying structure to the bearing chamber. This allows for oil spraying lubrication and cooling of the bearing during the operation of the high-temperature silk-forming machine, meeting the requirements of the high-temperature silk-forming machine with high lubrication performance.

[0022] like Figure 1 and Figure 2 As shown, the bearing oil spraying structure, which improves lubrication performance, includes a bearing housing 1, a bearing 2, a bearing sleeve 3, and a main shaft 4. The bearing 2 includes an inner ring 6 and an outer ring 5. The outer ring 5 is mounted on the bearing housing 1, and the inner ring 6 is mounted on the bearing sleeve 3. The bearing housing 1 and the bearing sleeve 3 provide support for the bearing 2. The bearing housing 1 is fixed and does not rotate with the main shaft 4. An oil spraying ring 7 is installed in the bearing housing 1, and an oil slinger sleeve 8 is fitted onto the main shaft 4. An oil reservoir 10 is circumferentially arranged on the side wall of the oil spraying ring 7. The oil spraying ring 7 and the shaft... Multiple oil injection holes 11 are circumferentially arranged on the end face corresponding to bearing 2. Each oil injection hole 11 is connected to the oil reservoir 10. The oil slinger sleeve 8 is arranged inside the oil injection ring 7. In actual use, lubricating oil is injected into the oil reservoir 10, and the lubricating oil is output through the oil injection holes 11, so that lubricating oil can be sprayed onto the outer wall of the oil slinger sleeve 8. The rotation of the main shaft 4 can drive the oil slinger sleeve 8 to rotate at high speed. The lubricating oil that is evenly sprayed into the outer wall of the oil slinger sleeve 8 will be quickly thrown out, so that the lubricating oil is evenly thrown onto the bearing 2, achieving the effect of lubrication and cooling.

[0023] It should be noted that since the bearing chamber 1 and the oil injection ring 7 are fixed and do not rotate, after the lubricating oil is injected into the oil reservoir 10, since other parts cannot discharge oil, the lubricating oil can only be sprayed out from the oil injection hole 11. The diameter of the oil injection hole 11 is smaller than the oil hole entering the oil reservoir 10. Therefore, the amount of lubricating oil entering the oil reservoir 10 at the beginning is less than the amount flowing out from the oil injection hole 11. When the oil reservoir 10 is full of lubricating oil, the amount entering the oil reservoir 10 and the amount flowing out per unit time are equal. Therefore, the lubricating oil will be pressurized and sprayed out, almost in a straight line into the oil slinger 8.

[0024] In some embodiments, to improve the oil-throwing effect, the oil injection hole 11 is gradually tilted closer to the axis of the oil injection ring 7, so that the lubricating oil sprayed through the oil injection hole 11 can fall smoothly onto the outer wall of the oil-throwing sleeve 8.

[0025] In other embodiments, the outer wall of the oil-throwing sleeve 8 is recessed to form an arc-shaped groove 14, which guides the direction of the lubricating oil being thrown out. The lubricating oil sprayed from the oil injection hole 11 falls into the arc-shaped groove 14, ensuring that most of the lubricating oil is thrown onto the bearing.

[0026] like Figure 2As shown, one end of the oil slinger 8 abuts against the inner ring 6, so that the inner ring 6 of the bearing is pre-tightened, while the other end of the oil slinger 8 is provided with a locking nut 9, which is sleeved on the main shaft 4, thereby pressing the oil slinger 8.

[0027] In other embodiments, the side wall of the oil injection ring 7 is provided with a first sealing groove 12, which is located on one side of the oil reservoir 10. At the same time, the oil injection ring 7 is provided with a second sealing groove 13 on the end face away from the oil injection hole 11. Both the first sealing groove 12 and the second sealing groove 13 are provided with sealing elements, which can enclose the oil reservoir 10, enhance the sealing performance of the oil reservoir 10, and ensure that the lubricating oil can always be sprayed out smoothly from the oil injection hole 11 to avoid lubricating oil leakage.

[0028] like Figure 2 As shown, the bearing housing 1 has multiple circular holes 15 arranged circumferentially, and the oil injection ring 7 has multiple threaded holes 16 correspondingly arranged, so that the oil injection ring 7 can be fixed to the bearing housing 1 by bolts, and the mating end face of the oil injection ring 7 and the bearing housing 1 can be tightened.

[0029] Meanwhile, the threaded hole 16 is located inside the first sealing groove 12, which can prevent lubricating oil from seeping out from the threaded hole 16.

[0030] Working principle:

[0031] In actual operation, lubricating oil is injected into the oil storage tank 10 and output through the oil spray hole 11, thereby spraying lubricating oil onto the outer wall of the oil slinger 8. The rotation of the main shaft 4 can drive the oil slinger 8 to rotate at high speed. The lubricating oil that is evenly sprayed into the outer wall of the oil slinger 8 will be quickly thrown out, thereby evenly throwing the lubricating oil onto the bearing to achieve the effects of lubrication and cooling.

[0032] like Figure 3 The diagram shown is a schematic of a high-temperature silkening machine using the above-mentioned bearing oil spraying structure. The moving grinding disc of the silkening unit 17 is connected to one end of the main shaft 4.

[0033] Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model are within the protection scope of this utility model.
