Description
Technical Field
[0001] The invention relates to the technical field of bearing lubrication, in particular to a bearing lubrication structure. Background Art
[0002] Bearings are one of the key components of mechanical equipment. Any defect in a bearing can cause equipment failure or even serious accidents. One of the important factors to ensure the normal operation and long service life of bearings is to ensure that the bearings are well lubricated. When the bearing lubricant is insufficient, the most primitive method is to use an oiler to add oil in time. However, this method makes it difficult to maintain a constant amount of oil, and there is a greater risk of forgetting to add oil due to negligence. Therefore, bearing lubrication mechanisms such as oil bath lubrication, splash lubrication and circulating oil lubrication have replaced manual oil supply.
[0003] In the prior art, the circulating oil lubrication mechanism of the bearing is to suck the lubricating oil from the oil tank through an oil pump and then transport it to the part of the bearing that needs lubrication, and then return it to the oil tank from the oil return port; the circulating oil lubrication mechanism is composed of an oil pump, a filter, an oil tank, an oil pipeline, etc.; during the long-term operation of the bearing, the rolling elements, outer rings and inner rings in the bearing are prone to produce iron debris during long-term operation. The filter in the circulating oil lubrication mechanism will filter the debris mixed in the lubricating oil during the circulation of the lubricating oil. As a result, the filter in the circulating oil lubrication mechanism needs to be removed and cleaned frequently to ensure the smooth flow of the oil circuit. However, in the process of disassembling and cleaning the filter, the staff needs to spend a lot of time to disassemble, clean and reinstall it. Moreover, when the bearing is running at high speed for a long time, if the filter is forgotten to be cleaned due to negligence, etc., it is easy to cause the filter to be blocked and the oil circuit to be blocked. During the operation of the bearing, a large amount of debris is retained inside and is not well lubricated, which is very likely to cause bearing damage or dangerous operation.

The clockwise rotation of the fan blades is limited by the speed of the driving gear, and the clockwise rotation is slow. The counterclockwise rotation of the fan blades is not limited by the speed, and the counterclockwise rotation is fast, so that when the fan blades rotate counterclockwise, the air flow on the surface of the outer casing is further accelerated, the temperature of the outer casing is reduced, thereby reducing the temperature of the lubricating oil in the outer casing, and thus improving the operating stability of the bearing.

DETAILED DESCRIPTION
[0040] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0041] Example 1:
[0042] A bearing lubrication structure, such as Figures 1-9As shown, it includes a main body 1, which is a common shell component with heat dissipation holes in this field; an oil pump 11 is installed near the inner wall of the main body 1, and the oil pump 11 draws oil from an external oil tank and transports it to the oil circuit, and realizes the function of keeping the lubricating oil in the entire oil circuit flowing. A filter device 2 is installed at a position on one side of the oil pump 11 in the main body 1, and the filter device 2 is used to filter the bearing lubricating oil; a distributor assembly 12 is installed on one side of the filter device 2 in the main body 1, and a control assembly 13 is installed between the distributor assembly 12 and the oil pump 11 in the main body 1, and the control assembly 13 is used to control the oil pump 11 and the distributor assembly 12; the filter device 2 includes: the distributor assembly 12 is a conventional bearing circulation lubrication system component, which is composed of an oil-gas distributor and a flow meter. The oil-gas distributor distributes the lubricating oil to each bearing, and the flow meter monitors the flow of the lubricating oil entering the oil-gas distributor. If the flow meter monitors that the flow of the lubricating oil entering the oil-gas distributor is low, the controller controls the oil pump 11 to increase the flow pressure of the lubricating oil;
[0043] The housing 21 is installed in the main body 1, and the housing 21 is connected to the oil pump 11 and the distributor assembly 12 through the oil pipe; the housing 21 is L-shaped;
[0044] A filter screen 22 is fixedly connected to the housing 21 near the distributor assembly 12;
[0045] The rotating shaft 23 is rotatably connected to the housing 21 near the filter 22, and both ends of the rotating shaft 23 are located outside the housing 21; the rotating connection between the rotating shaft 23 and the housing 21 is sealed, and the rotating shaft 23 is close to the distributor assembly 12;
[0046] The arc-shaped plate 24 is evenly fixed on the rotating shaft 23. The surface of one side corresponding to the area surrounded by the arc-shaped plate 24 is the inner wall of the arc-shaped plate 24, and the other side is the outer wall. The cleaning plate 241 is fixed on the side of the arc-shaped plate 24 close to the filter screen 22;
[0047] The collecting plate 25 is fixedly connected to the inner wall of the housing 21. A cleaning hole 211 is opened on one side of the housing 21 at a position corresponding to the collecting plate 25. A sealing block 212 is installed in the cleaning hole 211.
[0048] Cooling components 3 are installed on both sides of the housing 21, and the cooling components 3 realize the function of cooling the lubricating oil;
[0049] In the prior art, the circulating oil lubrication mechanism of the bearing draws the lubricating oil from the oil tank through an oil pump 11 and delivers it to the part of the bearing that needs lubrication, and then returns it to the oil tank through the oil return port; the circulating oil lubrication mechanism is composed of an oil pump 11, a filter, an oil tank, an oil pipeline, etc.; during the long-term operation of the bearing, the rolling elements, outer rings and inner rings in the bearing are prone to produce iron debris during the long-term operation, and the filter in the circulating oil lubrication mechanism filters the debris mixed in the lubricating oil during the lubricating oil circulation process. As a result, the filter in the circulating oil lubrication mechanism needs to be frequently disassembled and cleaned to ensure the smooth flow of the oil circuit. However, during the process of disassembling and cleaning the filter, the staff needs to spend a lot of time to disassemble, clean and reinstall it. Moreover, if the filter is forgotten to be cleaned due to negligence, it is easy to cause the filter to be clogged and the oil circuit to be blocked. During the operation of the bearing, a large amount of debris is retained inside and is not well lubricated, which is very likely to cause bearing damage or dangerous operation.
[0050] Specifically, after the installation is completed, the staff starts the lubrication mechanism through the control component 13. When the bearing is running at high speed, the oil pump 11 draws lubricating oil from the external oil tank and conveys the lubricating oil to the filter device 2 through the oil pipe by means of supercharging. After the lubricating oil enters the housing 21, it flows along the L-shaped inner wall of the housing 21. By increasing the flow path of the lubricating oil in the housing 21 within the limited space, the time for the lubricating oil to dissipate heat through the housing 21 is prolonged, thereby reducing the temperature of the lubricating oil. After the cooled lubricating oil flows into the bearing, it cools the bearing that has been running for a long time and generates high temperature, thereby reducing the operating temperature of the bearing and improving the operating stability of the bearing.
[0051] The lubricating oil flows in the housing 21 until it contacts the curved plate 24. The lubricating oil is pressurized by the oil pump 11, pushing the curved plate 24 to rotate. After pushing the curved plate 24 to rotate and passing over the curved plate 24, the lubricating oil contacts the filter 22. Iron debris on the bearing mixed with the lubricating oil is blocked by the filter 22 on the side close to the rotating shaft 23, while the lubricating oil passes through the filter 22 and flows into the distributor assembly 12 through the oil pipe. The controller controls the distributor assembly 12 to operate, thereby transporting the lubricating oil from the oil filling hole on the bearing to the inside of the bearing for lubrication. The lubricating oil inside the bearing then flows back into the oil tank through the oil outlet and the oil pipe and is again pumped out by the oil pump 11.
[0052] When the lubricating oil pushes the curved plate 24 to rotate, the curved plate 24 drives the cleaning plate 241 to rotate around the rotating shaft 23. During the rotation of the cleaning plate 241, the end of the cleaning plate 241 away from the curved plate 24 contacts and scrapes the side of the filter 22 close to the rotating shaft 23. The cleaning plate 241 scrapes the debris along the surface of the filter 22 close to the rotating shaft 23 to the collecting plate 25, thereby preventing the debris from accumulating on the side of the filter 22, which would reduce the fluidity of the lubricating oil and cause the bearing to be poorly lubricated. This improves the fluidity of the lubricating oil in the lubrication mechanism, increases the circulation effect of the lubricating oil, and further improves the stability of the bearing under long-term high-speed operation.
[0053] After the lubricating oil pushes the arc plate 24 to rotate, the arc plate 24 drives the rotating shaft 23 to rotate, and the rotation of the rotating shaft 23 drives the cooling component 3 to work. The cooling component 3 cools the lubricating oil in the shell 21, so that after the lubricating oil flows into the inside of the bearing, it cools the bearing that has generated high temperature due to long-term operation, reduces the operating temperature of the bearing, and thereby improves the operating stability of the bearing.
[0054] Example 2:
[0055] Example 2 is based on Example 1. Figure 5 and Figure 9 As shown, the portion of the collecting plate 25 close to the rotating shaft 23 is a permanent magnet; the arc-shaped plate 24 is made of hard plastic, and the cleaning plate 241 is made of elastic material;
[0056] The collecting plate 25 is fixedly connected to a guide plate 26 at a position away from the inner wall of the housing 21;
[0057] Specifically, during the rotation of the cleaning plate 241, the end of the cleaning plate 241 away from the curved plate 24 contacts and scrapes the side of the filter 22 close to the rotating shaft 23, and the cleaning plate 241 scrapes the debris along the surface of the filter 22 close to the rotating shaft 23 until the cleaning plate 241 drives the debris to contact the end of the collecting plate 25 farthest from the rotating shaft 23. Moreover, since the portion of the collecting plate 25 close to the rotating shaft 23 is a permanent magnet, and the curved plate 24 is made of hard plastic, when the curved plate 24 is close to the permanent magnet portion of the collecting plate 25, the rotation of the curved plate 24 will not be hindered by the magnetic influence, thereby affecting the flow of lubricating oil, thereby increasing the smoothness of the rotation of the curved plate 24, improving the cleaning efficiency of the cleaning plate 241 on the filter 22, and increasing the circulation effect of the lubricating oil, thereby improving the stability of the bearing under long-term high-speed operation;
[0058] By setting the cleaning plate 241 to be made of an elastic material, when the cleaning plate 241 drives the debris to contact the collecting plate 25, the debris is affected by the magnetism of the permanent magnet part of the collecting plate 25, so that the debris is adsorbed on the side of the collecting plate 25 close to the inner wall of the shell 21, thereby completing the cleaning work of the cleaning plate 241 on the filter 22; because the cleaning plate 241 is made of an elastic material, the curved plate 24 continues to rotate under the influence of the flow of lubricating oil, so that the curved plate 24 drives the cleaning plate 241 to rotate, and the cleaning plate 241 is squeezed by the collecting plate 25 and elastically deformed until the cleaning plate 241 rotates over the collecting plate 25, and then the cleaning plate 241 elastically recovers under the influence of its own elasticity and performs the next cleaning work, thereby increasing the smoothness of the rotation of the cleaning plate 241 and further improving the cleaning efficiency of the cleaning plate 241 on the filter 22;
[0059] When the lubricating fluid flows in the direction of the curved plate 24 in the housing 21, it first contacts the guide plate 26. The lubricating fluid is guided by the guide plate 26 to flow toward the curved plate 24 away from the oil pump 11, so that the lubricating fluid flows toward the inner wall of the curved plate 24, thereby better promoting the rotation of the curved plate 24, increasing the smoothness of the rotation of the curved plate 24, and further improving the cleaning efficiency of the cleaning plate 241 on the filter 22. In addition, when the lubricating oil flows through the guide plate 26, the narrow area formed by the guide plate 26 and the inner wall of the housing 21 increases the flow pressure of the lubricating fluid flowing therethrough, which is conducive to the lubricating fluid promoting the rotation of the curved plate 24, thereby increasing the smoothness of the rotation of the curved plate 24 and improving the cleaning efficiency of the cleaning plate 241 on the filter 22.
[0060] After the lubrication mechanism is finished, the staff will pull out the sealing block 212 from the cleaning hole 211, and use a tool to remove the debris on the collection plate 25, and finally plug the sealing block 212 back into the cleaning hole 211, eliminating the need for staff to disassemble and clean the filter, and improving the convenience of using the lubrication mechanism.
[0061] Example 3:
[0062] Example 3 is based on Example 2. Figure 5-Figure 6 As shown, the corners of the housing 21 are arranged in an arc shape, and the cross section of the filter 22 is an arc;
[0063] The filter holes in the filter screen 22 are long strips. A first piece 242 is fixedly connected to the end of the cleaning plate 241 away from the curved plate 24, and the position of the first piece 242 corresponds to the filter holes in the filter screen 22. The first piece 242 is made of elastic material and is curved.
[0064] Specifically, when the lubricating oil flows in the housing 21, the lubricating oil flows and contacts the corners of the housing 21. If the flow direction of the lubricating oil is suddenly changed by the corners of the housing 21, the lubricating oil flowing there will impact the corners of the housing 21. Under the long-term impact, the housing 21 will be deformed or even leak oil. Therefore, the corners of the housing 21 are set in an arc shape, so that the lubricating oil is guided by the arc at the corners of the housing 21 and flows toward the arc plate 24, reducing the impact of the lubricating oil on the corners of the housing 21, thereby protecting the housing 21 and preventing oil leakage.
[0065] Since the filter screen 22 has an arc-shaped cross section, and the end of the filter screen 22 close to the collecting plate 25 is located between the collecting plate 25 and the inner wall of the housing 21, the lubricating oil continuously washes away the debris on one side of the filter screen 22 when it contacts and flows through the filter screen 22. The debris is guided by the filter screen 22 and moves along the surface of one side of the filter screen 22, so that debris is not easily accumulated at the angle between the end of the filter screen 22 away from the collecting plate 25 and the inner wall of the housing 21, thereby maintaining smooth rotation of the cleaning plate 241. In addition, the arc-shaped guiding effect of the filter screen 22 cooperates with the cleaning plate 241 to scrape the debris on the filter screen 22, thereby improving the cleaning efficiency of the cleaning plate 241 on the filter screen 22, increasing the circulation effect of the lubricating oil, and thereby improving the stability of the bearing under long-term high-speed operation.
[0066] During the rotation of the cleaning plate 241, the first plate 242 is driven to rotate around the rotating shaft 23. The first plate 242 rotates and contacts the filter screen 22. The end of the first plate away from the cleaning plate 241 extends into the filter holes in the filter screen 22 to scrape and clean the debris stuck on the filter screen 22, thereby preventing the debris from being washed away by the lubricating oil and stuck in the filter holes in the filter screen 22, resulting in insufficient cleaning effect of the cleaning plate 241 on the filter screen 22. The cleaning efficiency of the cleaning plate 241 on the filter screen 22 is improved, the circulation effect of the lubricating oil is increased, and the stability of the bearing under long-term high-speed operation is improved. As the cleaning plate 241 rotates, the first piece 242 continues to scrape and clean the filter holes in the filter screen 22 until the first piece 242 contacts the inner wall of the shell 21. The first piece 242 is squeezed by the inner wall of the shell 21 and elastically deformed. The debris on the first piece 242 is affected by the centrifugal force of the cleaning plate 241 and is retained on the cleaning plate 241 and the first piece 242 until the cleaning plate 241 and the first piece 242 contact the collecting plate 25. The collecting plate 25 scrapes and collects the debris on the cleaning plate 241 and the first piece 242. The debris is magnetically affected by the collecting plate 25 and remains on the collecting plate 25.
[0067] Example 4:
[0068] Example 4 is based on Example 1. Figure 2-Figure 4 As shown, the cooling component 3 includes:
[0069] The driving gear 31 is fixedly connected to one end of the rotating shaft 23 outside the housing 21. The driving gear 31 is a common driving gear 31 and an incomplete gear, that is, half of the driving gear 31 has gear teeth and the other half has a smooth surface.
[0070] A driven shaft 32 is rotatably connected to the inner wall of the main body 1 near the driving gear 31, and the driven shaft 32 is close to the distributor assembly 12; a torsion spring is provided between the driven shaft 32 and the main body 1;
[0071] The driven gear 33 is fixedly connected to the end of the driven shaft 32 close to the driving gear 31, and the driven gear 33 is meshed with the driving gear 31; when the driving gear 31 drives the driven gear 33 to rotate to the smooth surface of the driving gear 31, the smooth surface of the driving gear 31 does not contact the driven gear 33; the oil pump 11 increases the pressure so that the force of the lubricating oil pushing the curved plate 24 and the rotating shaft 23 to rotate is greater than the force generated by the torsion spring on the driven shaft 32, and the force released after the torsion spring accumulates force can drive the driven shaft 32, the driven gear 33 and the fan blades 34 to rotate;
[0072] The fan blades 34 are evenly mounted on the driven shaft 32 between the driven gear 33 and the inner wall of the main body 1; when the fan blades 34 rotate counterclockwise, the fan blades 34 blow air toward the surface of the housing 21;
[0073] The housing 21 is evenly provided with heat sinks 35, and one end of the heat sink 35 faces the driven shaft 32; the heat sink 35 is evenly provided on the surface of the housing 21;
[0074] Specifically, the rotation of the rotating shaft 23 drives the driving gear 31 to rotate, and the toothed portion of the driving gear 31 drives the driven gear 33 to rotate clockwise, and the driven gear 33 drives the driven shaft 32 to rotate, and the driven shaft 32 drives the fan blades 34 to rotate clockwise, and the torsion spring between the driven shaft 32 and the main body 1 begins to accumulate force due to the rotation of the driven shaft 32, and the fan blades 34 rotate to accelerate the air flow on the surface of the housing 21, and cooperate with the heat dissipation holes in the main body 1 to cool the housing 21, thereby reducing the temperature of the lubricating oil in the housing 21, so that the cooled lubricating oil can cool the bearings that have generated high temperature due to long-term operation, reduce the operating temperature of the bearings, and thus improve the operating stability of the bearings;
[0075] When the driven gear 33 rotates to a position close to the smooth surface of the driving gear 31, the smooth surface of the driving gear 31 does not contact the driven gear 33, so that the driving gear 31 no longer drives the driven gear 33 to rotate. At this time, the torsion spring in the stored force state on the driven shaft 32 resets and drives the driven shaft 32 to quickly rotate counterclockwise to restore. The driven shaft 32 drives the fan blades 34 to rotate counterclockwise quickly. The clockwise rotation of the fan blades 34 is limited by the speed of the driving gear 31, and the clockwise rotation is slow. The counterclockwise rotation of the fan blades 34 is not limited by the speed and rotates counterclockwise quickly. When the fan blades 34 rotate counterclockwise, the air flow on the surface of the housing 21 is further accelerated, thereby reducing the temperature of the housing 21, thereby reducing the temperature of the lubricating oil in the housing 21, and thus improving the operating stability of the bearing.
[0076] When the fan blades 34 accelerate the air flow on the surface of the shell 21, since the heat sink 35 is provided on the surface of the shell 21, in the process of the heat sink 35 dissipating heat to the shell 21, the fan blades 34 accelerate the air flow on the surface of the shell 21 while reducing the temperature of the heat sink 35 itself, thereby improving the heat dissipation effect of the heat sink 35 on the shell 21; if the side of the heat sink 35 faces the fan blades 34, the air blown toward the shell 21 will be blocked by the side of the heat sink 35 close to the fan blades 34 when it contacts the surface of the shell 21, thereby narrowing the flow range of the air and affecting the heat dissipation of the shell 21. By setting one end of the heat sink 35 toward the driven shaft 32, the air blown toward the shell 21 will not be blocked by the heat sink 35 when the one end of the heat sink 35 faces the fan blades 34, thereby reducing the temperature of the shell 21 and the temperature of the lubricating oil in the shell 21, thereby improving the operating stability of the bearing.

[0078] Example 5 is based on Example 4. Figure 7-Figure 8 As shown, an annular groove 36 is provided on the driven shaft 32 between the driven gear 33 and the inner wall of the main body 1, and a sleeve 37 is rotatably connected in the annular groove 36; the fan blades 34 are mounted on the outer surface of the sleeve 37, and the inner surface of the sleeve 37 is evenly provided with grooves 371; a groove 321 is provided in the annular groove 36 at a position corresponding to the groove 371, and a rotating plate 322 is hinged in the groove 321, and a coil spring is provided between the rotating plate 322 and the groove 321; the end of the rotating plate 322 closest to the annular groove 36 is located in the groove 321, and the end of the rotating plate 322 closest to the sleeve 37 is located in the groove 371; the driving gear 31, the driven wheel, the driven gear 33, the sleeve 37 and the fan blades 34 are all made of lightweight materials, such as hard plastic;
[0079] A ball 361 is disposed in the annular groove 36 , and the ball 361 is located between the sleeve 37 and the annular groove 36 ;
[0080] Specifically, when the driven gear 33 rotates and contacts the toothed portion of the driving gear 31, the driven shaft 32 rotates clockwise, driving the rotating plate 322. The rotating plate 322 is squeezed and compressed by the inner surface of the sleeve 37 into the No. 1 groove 321 and continuously passes over the groove 371. At this time, the sleeve 37 and the fan blades 34 do not rotate. When the driven gear 33 rotates to approach the smooth surface of the driving gear 31, the driven shaft 32 rotates counterclockwise, driving the rotating plate 322 to rotate. The rotating plate 322 is affected by the coil spring and extends from the No. 1 groove 321 and abuts against the inner wall of the groove 371, so that the rotating plate 322 drives the sleeve 37 to rotate in the annular groove 36. The sleeve 37 drives the fan blades 34 to rotate counterclockwise, and the fan blades 34 blow air toward the surface of the housing 21.
[0081] The rotation of the driven gear 33 is slowed down by the rotation of the driven shaft 32, and the sleeve 37 drives the blade 34 to rotate slowly until the driven gear 33 rotates close to the smooth surface of the driving gear 31. The driven shaft 32 rotates counterclockwise again and drives the sleeve 37 and the blade 34 to rotate through the rotating plate 322. Because the clockwise rotation of the blade 34 is limited by the speed of the driving gear 31, the clockwise rotation is slow, and the counterclockwise rotation of the blade 34 is not limited by the speed and the counterclockwise rotation is fast, so that the amount of air blown toward the housing 21 by the blade 34 during the counterclockwise rotation increases, and the blade 34 keeps rotating counterclockwise for a long time, which improves the heat dissipation effect on the surface of the housing 21, further reduces the temperature of the housing 21, thereby reducing the temperature of the lubricating oil in the housing 21, and thus improving the operation stability of the bearing.
[0082] When the sleeve 37 rotates in the annular groove 36, a ball 361 is arranged in the annular groove 36, and the ball 361 is located between the sleeve 37 and the annular groove 36, so that the friction force generated by the rotation between the sleeve 37 and the annular groove 36 is reduced by the intervention of the ball 361, thereby increasing the smoothness of the rotation of the sleeve 37, avoiding the possibility that the sleeve 37 is affected by the friction force to slow down the rotation speed of the fan blade 34 and reduce the heat dissipation of the outer shell 21, thereby reducing the temperature of the outer shell 21, so that the lubricating oil in the outer shell 21 can obtain a good cooling effect, and improve the operating stability of the bearing.
[0083] Example 6:
[0084] Example 6 is based on Example 2. Figure 10 As shown, the difference from the above embodiment is that the surface of the collecting plate 25 is wrapped with cotton thread, and the collecting plate 25 is made of ordinary non-magnetic material, such as hard plastic;
[0085] Specifically, when installing the collecting plate 25, it can be divided into two parts. The collecting plate 25 close to the inner wall of the shell 21 is the collecting plate 25 part 1, and the collecting plate 25 away from the inner wall of the shell 21 is the collecting plate 25 part 2. Cotton thread is wrapped around the collecting plate 25 part 2. The collecting plate 25 part 1 is fixedly connected to the inner wall of the shell 21, and the collecting plate 25 part 2 is slidably installed with the collecting plate 25 part 1. When cleaning the collecting plate 25, the sealing block 212 is taken out, and then the collecting plate 25 part 2 is replaced, and finally the sealing block 212 is plugged in. This method is the same as that in the second embodiment. The difference between the cleaning method of the collection plate 25 and the cleaning method of the collection plate 25 is that the step of cleaning the collection plate 25 is omitted by replacing the collection plate 25, which increases the convenience of use, but the cost of replacing the collection plate 25 is higher than cleaning the collection plate 25; when the collection plate 25 collects debris, the cleaning plate 241 and the No. 1 plate 242 rotate to contact the collection plate 25, and the collection plate 25 scrapes the debris on the cleaning plate 241 and the No. 1 plate 242. The scraped debris is adhered to the cotton thread wrapped around the collection plate 25, thereby collecting the debris on the cleaning plate 241 and the No. 1 plate 242.
