Bearing lubrication structure and rotating equipment

Abstract

This application provides a bearing lubrication structure and a rotating device. The bearing lubrication structure includes a rotating component; multiple bearing bushes arranged in a ring array around the rotating component; and multiple heat-insulating oil supply assemblies located between adjacent bearing bushes. Each heat-insulating oil supply assembly includes an oil spray pipe and an oil separator plate. The oil separator plate contacts the rotating component, and the oil spray pipe supplies oil to at least one side of the oil separator plate. By arranging the heat-insulating oil supply assemblies between adjacent bearing bushes and separating them with oil separator plates, this application avoids the transfer of hot oil between adjacent bearing bushes. This reduces the amount of hot oil entering the bearing bushes while increasing the amount of cold oil entering, which helps lower the operating temperature of the bearing bushes. Simultaneously, the oil spray pipe provides oil lubrication to the bearing bushes via spraying, eliminating the need to immerse both the rotating component and the bearing in the lubricating medium, thus avoiding foaming and oil mist caused by the agitation of the rotating component.

Description

Technical Field

[0001] This application relates to the field of bearing lubrication technology, specifically to a bearing lubrication structure and a rotating device. Background Technology

[0002] Currently, for large rotating equipment, the rotation process generates a lot of heat, so the bearings need to be immersed in an oil tank to reduce the bearing temperature.

[0003] Taking the generator motor of a large rotating pumped storage device as an example, the generator motor has a rotating component, and a sliding rotor extends outward from the surface of the rotating component. A guide bearing and a thrust bearing are in contact with the sliding rotor. The guide bearing contacts the side of the sliding rotor to limit the radial movement of the shaft, and the thrust bearing contacts the bottom surface of the sliding rotor to limit the axial movement of the sliding rotor. The guide bearing, the sliding rotor, and the thrust bearing are all immersed in an oil tank to reduce the temperature of the guide bearing, the sliding rotor, and the thrust bearing.

[0004] However, since the bearing is immersed in the oil tank, the rotation of the sliding rotor relative to the bearing simultaneously agitates the lubricating medium in the oil tank, resulting in foaming and oil mist. Oil mist overflowing from the oil tank and adhering to the generator may cause short circuits, affecting the safe and stable operation of the generator motor. In addition, during the rotation of the rotating parts, hot oil flowing out of the upstream bearing in the opposite direction of rotation will enter the downstream bearing in the direction of rotation, which reduces the lubrication and cooling effect of the bearing. Summary of the Invention

[0005] This application provides a bearing lubrication structure and a rotating device, aiming to solve the technical problems of oil mist and poor lubrication and cooling effect in the bearing lubrication of large rotating equipment.

[0006] In a first aspect, this application provides a bearing lubrication structure, comprising:

[0007] Rotating component;

[0008] Multiple bearing bushes are arranged in a ring array around the rotating component;

[0009] Multiple heat-insulated oil supply components are located between adjacent bearing bushes;

[0010] The heat-insulating oil supply assembly includes an oil injection pipe and an oil separator plate. The oil separator plate is in contact with the rotating part, and the oil injection pipe supplies oil to at least one side of the oil separator plate.

[0011] In some embodiments, the fuel injection pipe has an opening extending along its axial direction;

[0012] An oil separator is installed inside the opening, and the width of the oil separator is smaller than the width of the opening.

[0013] In some embodiments, the oil separator divides the opening into a first fuel injector and a second fuel injector, with the first fuel injector and the second fuel injector located on opposite sides of the oil separator.

[0014] In some embodiments, the first and second fuel injectors are arranged symmetrically with respect to the oil separator.

[0015] In some embodiments, the heat-insulating oil supply assembly further includes a fixed base and a sliding base;

[0016] The sliding seat is slidably mounted on the fixed seat, and the fuel injection pipe is mounted on the sliding seat.

[0017] In some embodiments, the sliding seat has an arcuate groove for receiving the fuel injection pipe, the fuel injection pipe being embedded in the arcuate groove;

[0018] The sliding seat has a mounting surface flush with the opening on the side opposite to the fixed seat. An adjustment plate is mounted on the mounting surface, and the adjustment plate is connected to the oil separator plate.

[0019] In some embodiments, the adjustment plate is provided with a through hole opposite to the opening;

[0020] The cross-sectional area of ​​the through hole gradually increases in the direction away from the opening.

[0021] In some embodiments, the heat-insulating oil supply assembly further includes a first bracket and a second bracket, wherein the second bracket is detachably mounted on the first bracket and the fixing seat is fixedly mounted on the second bracket.

[0022] In some embodiments, the oil separator includes a fixed plate and a lifting plate;

[0023] A first strip groove is provided on the side of the fixed plate adjacent to the rotating part, and the lifting plate is installed in the first strip groove.

[0024] In some embodiments, a spring is installed in the first strip groove;

[0025] One end of the spring is fixed to the bottom of the first groove, and the other end is in contact with the lifting plate.

[0026] In some embodiments, the lifting plate is provided with a limiting hole along the depth direction of the first strip groove;

[0027] A limiting component is installed on the fixed plate. The limiting component is embedded in the limiting hole, and the length of the limiting hole along the depth direction of the first strip groove is greater than the diameter of the limiting component.

[0028] In some embodiments, the side of the lifting plate adjacent to the rotating member is provided with a second strip-shaped groove;

[0029] The lifting plate has a first oil scraping part and a second oil scraping part located on both sides of the second strip groove, and the first oil scraping part and the second oil scraping part are in contact with the rotating part.

[0030] In some embodiments, the side of the fixing plate is provided with a threaded hole that extends through the first strip groove, and a locking screw is installed in the threaded hole. The locking screw extends into the first strip groove and presses against the lifting plate.

[0031] In some embodiments, the lifting plate is made of polyetheretherketone or polytetrafluoroethylene.

[0032] In a second aspect, this application provides a rotating device including a bearing lubrication structure as described in the first aspect.

[0033] This application arranges a heat-insulating oil supply assembly between adjacent bearing bushes. Since the oil baffle plate is in contact with the rotating parts, the oil baffle plate of the heat-insulating oil supply assembly separates the adjacent bearing bushes, which can prevent the transfer of hot oil between the two adjacent bearing bushes. While reducing the amount of hot oil entering the bearing bushes, it can increase the amount of cold oil entering the bearing bushes, which is beneficial to reducing the operating temperature of the bearing bushes. At the same time, since the oil injection pipe can supply oil to at least one side of the oil baffle plate, the oil injection pipe supplies oil lubrication to the bearing bushes in a spray manner, without immersing the rotating parts and bearings in the lubricating medium, thereby avoiding foam and oil mist phenomena generated by the agitation of the rotating parts.

Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0051] This application provides a bearing lubrication structure and a rotating device, which will be described in detail below.

[0052] First, refer to Figure 1 as well as Figure 2 , Figure 1 This paper shows a front view of a bearing lubrication structure according to an embodiment of the present application. Figure 2 A left view of a bearing lubrication structure according to an embodiment of this application is shown, wherein the bearing lubrication structure includes:

[0053] Rotating component 10;

[0054] Multiple bearing bushes 20 are arranged in a ring array around the rotating component 10;

[0055] Multiple heat-insulating oil supply components 30 are located between adjacent bearing bushes 20;

[0056] The heat-insulating oil supply assembly 30 includes an oil injection pipe 31 and an oil separator 32. The oil separator 32 is in contact with the rotating member 10, and the oil injection pipe 31 supplies oil to at least one side of the oil separator 32.

[0057] Specifically, the rotating component 10 refers to the rotating object of any large rotating equipment, such as the shaft of a generator motor, water pump turbine, wind turbine, etc., or a sliding rotor or mirror plate connected to the rotating shaft of a generator motor and rotating with it. Generally, the rotating component 10 carries some rotating parts. Taking a generator motor as an example, a rotor is installed on the rotating shaft of the generator motor, and a stator is arranged around the rotor. Electricity is generated by the rotor cutting the magnetic field lines of the stator.

[0058] In some embodiments of this application, see Figure 3 , Figure 3 This diagram illustrates a structural embodiment of the rotating component 10 and the bearing bush 20 cooperating. The rotating shaft of the generator includes a shaft body 11, with a sliding rotor 12 connected to the shaft body 11. A mirror plate 13 is arranged on the sliding rotor 12 in a direction perpendicular to the axis of the shaft body 11. The bearing bush 20 contacts the lower surface of the mirror plate 13, thereby achieving the purpose of supporting the rotating shaft of the generator in the axial direction. At the same time, the oil tank 50 encloses the sliding rotor 12 and the bearing bush 20 to prevent lubricating oil leakage. It can be understood that the bearing bush 20 in contact with the mirror plate 13 is a thrust bearing bush 21. In fact, the bearing bush 20 can also be a guide bearing bush 22, such as a guide bearing bush 22 installed on the side of the sliding rotor 12, to limit the radial movement of the rotating shaft of the generator.

[0059] In some embodiments of this application, the rotating shaft of the generator can be arranged vertically or horizontally, such as the rotating shaft of a horizontal or vertical generator. It is understood that the rotating shaft of the generator can also be arranged at an angle.

[0060] The bearing bushes 20 are arranged in a ring array around the rotating member 10 to limit the radial and / or axial movement of the rotating member 10. In some embodiments of this application, such as embodiments where the rotating member 10 includes a sliding rotor 12 and / or a mirror plate 13, see [reference needed]. Figure 3 The bearing bush 20 includes multiple guide bearing bushes 22, which are arranged in a ring array at intervals and contact the surface of the sliding rotor 12 opposite to the shaft body 11; and / or the bearing bush 20 includes multiple thrust bearing bushes 21, which are arranged in a ring array at intervals and contact the mirror plate 13. The guide bearing bushes 22 restrict the radial movement of the rotating component 10, and the thrust bearing bushes 21 restrict the axial movement of the rotating component 10, thereby achieving the purpose of the bearing bush 20 restricting the radial and axial movement of the rotating component 10. Understandably, the bearing bush 20 can form a bearing structure with other structures, such as a bearing housing, an insulating plate, etc.

[0061] The heat-insulating oil supply assembly 30 is used to isolate the hot oil between two adjacent bearing shells 20, while providing spray-type lubrication to achieve the purpose of oil transfer between bearing shells and oil supply between bearing shells. The heat-insulating oil supply assembly 30 includes an oil spray pipe 31 and an oil separator plate 32. The oil separator plate 32 contacts the rotating member 10, and the oil spray pipe 31 supplies oil to at least one side of the oil separator plate 32. In some embodiments of this application, the end of the oil spray pipe 31 facing away from the rotating member 10 is connected to the oil supply pipe 40 to achieve the purpose of supplying oil to the oil spray pipe 31. In some embodiments of this application, for example, for embodiments where the bearing shell 20 includes multiple thrust bearing shells 21, the oil separator plate 32 and the oil spray pipe 31 are arranged along the radial direction of the rotating member 10, thereby blocking the heat oil transfer process between adjacent thrust bearing shells 21 in the radial direction. In other embodiments of this application, such as for an embodiment where the bearing 20 includes a plurality of guide bearing bearings 22, the oil baffle 32 and the oil injection pipe 31 are arranged along the axial direction of the rotating member 10, while the oil baffle 32 is in contact with the surface of the sliding rotor 12 to avoid the hot oil transfer process between adjacent guide bearing bearings 22.

[0062] In this embodiment, by arranging a heat-insulating oil supply assembly 30 between adjacent bearing bushes 20, since the oil baffle 32 is in contact with the rotating component 10, the oil baffle 32 of the heat-insulating oil supply assembly 30 separates the adjacent bearing bushes 20, which can prevent the phenomenon of hot oil being transferred between the two adjacent bearing bushes 20. While reducing the amount of hot oil entering the bearing bushes 20, it can increase the amount of cold oil entering the bearing bushes 20, which is beneficial to reducing the working temperature of the bearing bushes 20. At the same time, since the oil spray pipe 31 can supply oil to at least one side of the oil baffle 32, the oil spray pipe 31 supplies oil lubrication to the bearing bushes 20 by spraying, without immersing the rotating component 10 and the bearing in the lubricating medium, thereby avoiding the foam and oil mist phenomenon generated by the agitation of the rotating component 10.

[0063] Furthermore, in some embodiments of this application, see [reference]. Figure 4 as well as Figure 5 , Figure 4 This application shows Figure 1 An enlarged schematic diagram of point A in the middle. Figure 5A schematic diagram of an embodiment of the present application shows a fuel injection pipe 31, wherein the fuel injection pipe 31 has an opening 311 extending along its axial direction, and an oil separator 32 is installed inside the opening 311, with the width of the oil separator 32 being smaller than the width of the opening 311. Because the oil separator 32 is installed inside the opening 311, the space occupied by the fuel injection pipe 31 and the oil separator 32 can be reduced, which not only facilitates the installation of the heat-insulating oil supply assembly 30, but also increases the diameter of the fuel injection pipe 31 to improve the lubricating oil supply. Simultaneously, since the width of the oil separator 32 is smaller than the width of the opening 311, meaning the oil separator 32 does not completely block the opening 311, the lubricating oil in the fuel injection pipe 31 can be sprayed out through the gap in the opening 311 at the oil separator 32. This not only ensures lubricating oil supply, but also increases the spray speed of the lubricating oil through the gap in the opening 311 at the oil separator 32, thereby achieving a better spray lubrication effect. It is understood that the fuel injection pipe 31 and the oil separator 32 can also be installed side by side.

[0064] In some embodiments of this application, see further reference. Figure 4 The oil separator 32 divides the opening 311 into a first oil injection port 312 and a second oil injection port 313, with the first and second oil injection ports 312 and 313 located on opposite sides of the oil separator 32. For the pumped-storage generator motor, the rotation direction is different when the motor is used as a generator and when it is used as a motor; therefore, the direction of hot oil transfer between the bearings 20 is different, and the direction of the required lubricating oil supply is also different. (See reference...) Figure 6 as well as Figure 7 , Figure 6 This illustration shows a lubrication diagram of the rotating component 10 rotating in a first direction according to an embodiment of this application. Figure 7 This illustration shows a lubrication diagram of the rotating component 10 rotating in the second direction in an embodiment of this application. Since the first oil injection port 312 and the second oil injection port 313 are located on opposite sides of the oil separator 32, the first oil injection port 312 and the second oil injection port 313 can provide lubricating oil to the bearing 20 downstream in the rotation direction, regardless of whether the generator motor rotates forward or backward, thereby achieving the purpose of bidirectional rotational oil supply to the generator motor.

[0065] In some embodiments of this application, the first oil injection port 312 and the second oil injection port 313 are symmetrically arranged relative to the oil baffle plate 32. That is, the first oil injection port 312 and the second oil injection port 313 can provide lubricating medium with equivalent flow rates, which can ensure the lubrication effect of the bearing 20 regardless of whether the generator motor rotates forward or backward.

[0066] In some embodiments of this application, see further reference. Figure 4The heat-insulating oil supply assembly 30 also includes a fixed base 33 and a sliding base 34; the sliding base 34 is slidably mounted on the fixed base 33, and the oil injection pipe 31 is mounted on the sliding base 34. When installing or maintaining the heat-insulating oil supply assembly 30, the oil injection pipe 31 and the oil separator 32 can be installed between the bearing bushes 20 or removed by moving the sliding base 34, thereby reducing the difficulty of installing and maintaining the heat-insulating oil supply assembly 30.

[0067] In some embodiments of this application, such as in an embodiment where the bearing bush 20 includes a plurality of thrust bearing bushes 21, the sliding direction of the sliding seat 34 relative to the fixed seat 33 is along the radial direction of the rotating member 10. In other embodiments of this application, such as in an embodiment where the bearing bush 20 includes a plurality of guide bearing bushes 22, the sliding direction of the sliding seat 34 relative to the fixed seat 33 is along the axial direction of the rotating member 10.

[0068] It is understandable that the sliding seat 34 can be fixed relative to the fixed seat 33 by screws, pins or blocks to prevent the sliding seat 34 from sliding during the operation of the fuel injection pipe 31.

[0069] For further information, please refer to [link / reference]. Figure 4 In some embodiments of this application, the sliding seat 34 has an arc-shaped groove 341 for accommodating the oil injection pipe 31, and the oil injection pipe 31 is embedded in the arc-shaped groove 341. The side of the sliding seat 34 opposite to the fixed seat 33 has a mounting surface 342 flush with the opening 311, and an adjusting plate 35 is mounted on the mounting surface 342, which is connected to the oil separator plate 32. Since the oil injection pipe 31 is fixed in the arc-shaped groove 341 of the sliding seat 34, the arc-shaped groove 341 can wrap around the oil injection pipe 31, thereby better fixing the oil injection pipe 31 and avoiding the phenomenon of the oil injection pipe 31 shaking due to excessive pressure of the lubricating medium sprayed out; at the same time, by installing the oil separator plate 32 through the adjusting plate 35, the stability of the oil separator plate 32 can also be improved, and the oil separator plate 32 in contact with the rotating part 10 can be prevented from shaking during the rotation process, which would lead to a decrease in the hot oil isolation performance of the oil separator plate 32.

[0070] For example, the adjusting plate 35 can be directly welded to the side of the oil separator 32 to facilitate the mounting of the oil separator 32 onto the sliding seat 34. Understandably, the adjusting plate 35 can also be connected to the oil separator 32 by bolts or rivets.

[0071] In some embodiments of this application, see Figure 8 , Figure 8This paper illustrates another structural schematic diagram of the heat-insulating oil supply assembly 30 in an embodiment of this application. The heat-insulating oil supply assembly 30 further includes a first bracket 36 and a second bracket 37. The second bracket 37 is detachably mounted on the first bracket 36, and a fixed seat 33 is fixedly mounted on the second bracket 37. The first bracket 36 and the second bracket 37 provide support for the fixed seat 33, allowing the oil injection pipe 31 and the oil separator 32 to be close to the rotating component 10 (e.g., the sliding rotor 12 or the mirror plate 13). During installation within the unit, the heat-insulating oil supply assembly 30 can be installed simultaneously with the thrust bearing and the bearing bush 20. Later, during maintenance of the pumped storage power station, the parts of the heat-insulating oil supply assembly 30 requiring maintenance (e.g., the sliding seat 34, the oil injection pipe 31, and the oil separator 32) can be removed by disassembling the second bracket 37, without needing to remove the entire thrust bearing or bearing bush 20, thus reducing the maintenance difficulty of the heat-insulating oil supply assembly 30.

[0072] For further information, please refer to [link / reference]. Figure 4 , Figure 9 as well as Figure 10 , Figure 9 This shows a schematic diagram of one structure of the oil separator 32 and the adjustment plate 35 in an embodiment of this application. Figure 10 This paper shows a top view of the oil separator plate 32 and the adjustment plate 35 in an embodiment of this application. In some embodiments of this application, the adjustment plate 35 is provided with a through hole 351 opposite to the opening 311. The cross-sectional area of ​​the through hole 351 gradually increases in the direction away from the opening 311. When the fluid flows to the through hole 351, the cross-section of the through hole 351 gradually increases. The narrower part of the through hole 351 can accelerate the spraying speed of the lubricating medium, while the wider part can increase the area of ​​lubricating medium spraying. Thus, the spraying lubrication effect of the heat insulation oil supply assembly 30 is improved through the through hole 351 at the adjustment plate 35.

[0073] In some embodiments of this application, see Figure 9 The oil separator 32 includes a fixed plate 321 and a lifting plate 322. The fixed plate 321 has a first strip-shaped groove 3211 on its side adjacent to the rotating component 10, and the lifting plate 322 is installed within the first strip-shaped groove 3211. After the heat-insulating oil supply assembly 30 is installed between adjacent bearing bushes 20, the lifting plate 322 of the oil separator 32 contacts the rotating component 10. Since the lifting plate 322 is installed within the first strip-shaped groove 3211, during maintenance of the heat-insulating oil supply assembly 30, only the lifting plate 322 needs to be replaced, without replacing the entire oil separator 32. This reduces both maintenance difficulty and cost. For example, the lifting plate 322 is made of polyetheretherketone (PEEK) or polytetrafluoroethylene (PTFE) wear-resistant lubricating material. The excellent high-temperature resistance, mechanical properties, and self-lubricating properties of PEEK or PTFE enhance the hot oil isolation performance of the oil separator 32.

[0074] In some embodiments of this application, see further reference. Figure 9 A spring 323 is installed in the first groove 3211; one end of the spring 323 is fixed to the bottom of the first groove 3211, and the other end is in contact with the lifting plate 322. During the operation of the heat insulation oil supply assembly 30, the spring 323 is in a compressed state, thereby generating elastic force. The spring 323 keeps the lifting plate 322 in contact with the rotating part 10, thereby ensuring the hot oil isolation performance of the oil separator 32.

[0075] Understandably, spring 323 can also be replaced by other elastic elements, such as rubber elastic elements.

[0076] Furthermore, in some embodiments of this application, see [reference]. Figure 11 as well as Figure 12 , Figure 11 This paper shows a front view of the oil separator 32 and the adjustment plate 35 in an embodiment of this application. Figure 12 This application shows Figure 11 An enlarged schematic diagram at point B shows that the lifting plate has a limiting hole 3221 along the depth direction of the first strip groove 3211; a limiting member 3212 is installed on the fixing plate 321, the limiting member 3212 is embedded in the limiting hole 3221, and the length of the limiting hole 3221 along the depth direction of the first strip groove 3211 is greater than the diameter of the limiting member 3212. Due to the cooperation of the limiting member 3212 and the limiting hole 3221, the vertical movement distance of the lifting plate is the length of the limiting hole 3221 along the depth direction of the first strip groove 3211, thus avoiding the phenomenon of the lifting plate and the rotating member 10 being too tight or too loose. For example, the limiting member 3212 can be a pin or a screw.

[0077] For further information, please refer to [link / reference]. Figure 9 In some embodiments of this application, the lifting plate 322 has a second strip groove 3222 on the side adjacent to the rotating member 10; the lifting plate 322 has a first oil scraping part 3223 and a second oil scraping part 3224 located on both sides of the second strip groove 3222. The first oil scraping part 3223 and the second oil scraping part 3224 are in contact with the rotating member 10. Since the lifting plate 322 and the rotating member 10 are in contact at two places at the same time, the purpose of two-stage oil separation and oil scraping can be achieved.

[0078] Understandably, a greater number of second strip grooves 3222 can be provided on the side of the lifting plate 322 adjacent to the rotating member 10, so that the lifting plate 322 has a greater number of oil scraping parts, further improving the oil separation and oil scraping performance of the oil separator 32.

[0079] Furthermore, in some embodiments of this application, see [reference]. Figure 11The side of the fixing plate 321 is provided with a threaded hole 3213 that extends through to the first strip groove 3211. A locking screw 3214 is installed in the threaded hole 3213. The locking screw 3214 extends into the first strip groove 3211 and presses against the lifting plate 322. The locking screw 3214 can limit the shaking of the lifting plate 322 in the first strip groove 3211, so as to avoid the phenomenon that the shaking of the lifting plate 322 will cause the hot oil isolation performance of the oil separator 32 to decrease.

[0080] It is worth noting that the above description of the bearing lubrication structure and rotating equipment is intended to clearly illustrate the implementation and verification process of this application. Under the guidance of this application, those skilled in the art can also make equivalent design modifications, such as setting the oil injection pipe 31 on the oil separator 32, or setting the oil injection pipe 31 on the opposite sides of the oil separator 32, so as to achieve the purpose of isolating hot oil and spraying lubricating oil.
