Description

Technical Field

[0001] The present application relates to the field of bearings, and in particular to a cage and a rolling bearing having the cage. Background Art

[0002] Ball bearings are a type of rolling bearings. The ball is installed between the inner and outer steel rings. It can withstand large loads, and the ball is positioned and retained by a cage.

[0003] At present, when the bearing is in operation, the cage will bear the impact and vibration of the ball. When the bearing is used in a scene with a constantly changing speed, the cage needs to bear greater impact and vibration, resulting in a decrease in the service life of the bearing. In this process, the friction between the cage and the ball will also increase, which will also reduce the service life of the bearing. Summary of the invention

[0004] In order to increase the service life of a bearing, the present application provides a retaining frame and a rolling bearing having the retaining frame.

[0005] The present application provides a cage and a rolling bearing having the cage, which adopts the following technical solution: A retaining frame comprises two relatively arranged annular frames, wherein an arc-shaped retaining portion is formed on the annular frames, and when the two annular frames are connected, the corresponding retaining portions are surrounded to form an annular constraint groove, anti-vibration spring plates are arranged at both ends of the retaining portion of the annular frame, and an oil storage chamber is formed between the anti-vibration spring plates and the retaining portion, an oil inlet connected to the oil storage chamber is provided on the outer wall of the retaining portion of the annular frame, and a plurality of oil outlets connected to the oil storage chamber are provided on the anti-vibration spring plates; sealing baffles are arranged on the upper and lower edges of the anti-vibration spring plates, which together with the retaining portion form a closed oil storage space.

[0006] By adopting the above technical solution, the ball is located between the two annular bracket retaining parts and between the anti-vibration springs. When the rotation speed of the bearing changes, the rotation speed of the ball will also change. Therefore, the impact force between the ball and the retaining frame will increase, and the impact force will act on the anti-vibration spring, which will cause a certain deformation of the anti-vibration spring, thereby unloading the impact force, that is, buffering and reducing vibration of the ball and the retaining frame, which helps to increase the service life of the bearing; in addition, lubricating grease can be timely added to the oil storage chamber from the oil inlet, and the lubricating grease can be discharged from the oil outlet and lubricated on the outer wall of the ball, and the oil inlet This can ensure that the ball is lubricated without dead angles and prevent excessive friction between the ball and the inner wall of the retaining part; when the ball hits the anti-vibration spring and drives the anti-vibration spring to deform, the anti-vibration spring will squeeze the grease in the oil storage chamber to produce a pumping effect. At this time, the grease will be discharged from the oil outlet and the grease will quickly adhere to the surrounding side of the ball. When the ball hits the anti-vibration spring, the friction between the two will increase. The discharge of grease can reduce the friction between the ball and the anti-vibration spring, preventing excessive friction from causing wear on the ball or generating a lot of heat, thereby further improving the service life of the bearing.

[0007] Preferably, the annular frame is located in the oil storage chamber and has V-shaped folding springs arranged opposite to each other, the openings of the two folding springs are arranged facing each other, one end of the folding spring is connected to the anti-vibration spring, and the other end of the folding spring is connected to the inner wall of the retaining part.

[0008] By adopting the above technical scheme, the folding spring sheet supports the anti-vibration spring sheet. When the bearing rotates, the ball will always generate a certain impact force on the cage, thereby driving the cage to rotate synchronously. If the anti-vibration spring sheet is easily deformed, the ball will vibrate back and forth in the cage, which will affect the use of the bearing. Therefore, the anti-vibration spring sheet is supported by the folding spring sheet so that the anti-vibration spring sheet will only deform to reduce the impact when it is impacted by a larger impact force. When the anti-vibration spring sheet is deformed, the folding spring sheet will also be deformed. Since the oil storage chamber contains lubricating grease, the two folding spring sheets will squeeze and transport the lubricating grease to the middle, and then the squeezing of the grease by the bending of the anti-vibration spring sheet can ensure that the lubricating grease can be discharged smoothly and quickly from the oil outlet.

[0009] Preferably, a disturbance wing is extended from the bottom of the anti-vibration spring, and a smoothing sheet is bent at the bottom of the disturbance wing.

[0010] By adopting the above technical solution, when the bearing rotates, the disturbance wing will rotate synchronously with the retaining frame, and the spreading piece of the disturbance wing will spread the grease in the inner ring raceway of the bearing evenly, thereby ensuring that the ball rolls more smoothly; and when the retaining frame rotates, the disturbance wing can also stir the grease to improve the fluidity of the grease.

[0011] Preferably, a receiving piece is formed on the side close to the spreading piece of the two disturbance wings on the same side, and the receiving piece and the spreading piece are both inclined, and the spreading piece and the receiving piece are triangular.

[0012] By adopting the above technical solution, the smearing sheet and the receiving sheet are arranged in a triangular shape. When the bearing rotates, the smearing sheet and the receiving sheet rotate with the retaining frame, and the rotation speed of the bearing is different from the rotation speed of the retaining frame. Therefore, when the smearing sheet and the receiving sheet rotate, the grease in the inner ring raceway will be evenly stirred and the shape of the grease will be corrected. The shape of the grease will adapt to the triangular shape arranged by the smearing sheet and the receiving sheet, and then the bottom sides of the ball bearings can contact with the grease, thereby improving the lubrication effect on the ball bearings.

[0013] Preferably, the lower side of the anti-vibration spring is connected to the disturbance wing through a flexible deformation sheet, and the two disturbance wing sheets on the same side are connected through a positioning pin. The disturbance wing is provided with a plug-in hole for plugging with the positioning pin, and the aperture of the plug-in hole is larger than the diameter of the positioning pin.

[0014] By adopting the above technical scheme, when the anti-vibration spring piece expands outward due to the impact, the two disturbance wings cannot expand outward because they are connected by the positioning pin. Therefore, under the action of the flexible deformation piece, the two disturbance wings will bend inward, and the aperture of the plug-in hole is larger than the diameter of the positioning pin. The existence of the pore can ensure the rotation of the disturbance wing; when the disturbance wing bends, it will drive the receiving plate to rotate, and the ends of the two receiving plates close to each other will be displaced in the vertical direction to a certain extent, and the smoothing plate will rotate, which will move the lubricating grease toward the receiving plate, so that the lubricating grease will accumulate partially between the two receiving plates; that is, when an impact occurs, the lubricating grease will gather in the middle of the inner ring raceway, and the lubricating grease will subsequently cushion the ball, and more lubricating grease will adhere to the ball, which can timely and effectively reduce the friction between the ball and the anti-vibration spring piece.

[0015] A rolling bearing comprises an inner ring, an outer ring, a cage and balls, wherein the cage is the cage mentioned above.

[0016] Preferably, a sealing ring is arranged between the inner ring and the outer ring, an arc-shaped spring piece is arranged inside the sealing ring, and the center of curvature of the arc-shaped spring piece is located on the side away from the bearing, a first abutment groove is formed on the inner side of the outer ring, and a second abutment groove is formed on the outer side of the inner ring, and both ends of the sealing ring are plugged into the first abutment groove and the second abutment groove.

[0017] By adopting the above technical solution, when installing the sealing ring, the sealing ring is further bent along its bending direction, and then embedded between the inner ring and the outer ring until the upper and lower ends of the sealing ring enter the first abutment groove and the second abutment groove, thereby achieving the installation and fixation of the sealing ring.

[0018] Preferably, a first guide portion is formed on the outer edge of the outer ring, an annular spring sheet is formed on the outer edge of the inner ring, a second guide portion is formed on the annular spring sheet, the first guide portion and the second guide portion are arranged opposite to each other, an abutment portion is formed on the annular spring sheet, and the abutment portion serves as an inner wall of one side of the second abutment groove.

[0019] By adopting the above technical solution, during the actual installation process of the sealing ring, the sealing ring moves inward along the first guide part and the second guide part, and the annular spring sheet will be deformed under the action of the arc-shaped spring sheet, so that the sealing ring can quickly enter the first abutment groove and the second abutment groove, and then the annular spring sheet is reset to limit the sealing ring; during disassembly, the annular spring sheet is pressed down by a flat sheet-like tool. When the annular spring sheet is pressed down to the bottom of the sealing ring, the sheet tool contacts the sealing ring and the sealing ring moves outward a certain distance. At this time, the sheet-like tool can be inserted into the sealing ring, and then the tool rotates around the annular spring sheet for one circle to make the sealing ring smoothly come out; this sealing ring installation structure can make the disassembly and assembly of the sealing ring faster and more convenient.

[0020] In summary, the present application includes at least one of the following beneficial technical effects: 1. The ball is constrained between the anti-vibration springs. When the speed changes suddenly, the impact kinetic energy generated by the ball acts on the anti-vibration springs, and energy absorption is achieved through elastic deformation, effectively reducing vibration transmission. The oil storage chamber is replenished with lubricating grease through the oil inlet, and the porous oil outlet ensures that the lubricating grease evenly covers the surface of the ball, eliminating the lubrication blind area. When the impact force causes the anti-vibration spring to deform, the volume change of the oil storage chamber produces a pumping effect, which prompts the lubricating grease to quickly seep out to form a dynamic oil film, forming effective isolation at the friction interface, and realizing impact buffering and friction optimization simultaneously; 2. During the rotation of the bearing, the disturbance wing produces a shearing effect on the lubricating grease in the bearing raceway, and the smearing blade simultaneously adjusts the oil film thickness. The dynamic disturbance effect not only improves the uniformity of the lubricating grease distribution, but also enhances the heat dissipation efficiency through the conversion of fluid kinetic energy, forming active lubrication; 3. When the anti-vibration spring is deformed under the impact load, the flexible deformation sheet allows the disturbance wing to produce adaptive deflection, thereby changing the distribution pattern of lubricating grease. This dynamic adjustment mechanism can cause the lubricating grease to be enriched in the contact area when the impact occurs, forming a transient pressurized lubrication effect, and can buffer the movement of the ball; 4. Under the action of the first guide part and the second guide part, the installation efficiency of the sealing ring is significantly improved. When disassembling, the sealing ring can be quickly disassembled by pressing down the annular spring piece with a special tool, which greatly simplifies the maintenance operation process.

DETAILED DESCRIPTION

[0023] The following is combined with Figure 1 -Attached Figure 8 This application is described in further detail.

[0024] The embodiment of the present application discloses a retaining frame.

[0025] Example 1 Reference Figure 1 The retaining frame includes two ring frames 1 arranged opposite to each other, and the two ring frames 1 are fixedly connected by a bolt. The ring frames 1 are formed with an arc-shaped retaining portion 2. After the two ring frames 1 are connected, the corresponding retaining portion 2 is surrounded by an annular constraint groove 3 to position and retain the ball 60. The ring frame 1 is integrated with anti-vibration springs 4 at both ends of the retaining portion 2, and an oil storage chamber 5 is formed between the anti-vibration springs 4 and the retaining portion 2. The outer wall of the ring frame 1 located on the retaining portion 2 is provided with an oil inlet 21 connected to the oil storage chamber 5, and the anti-vibration springs 4 are provided with a plurality of oil outlets 41, which are connected to the oil storage chamber 5. The upper and lower edges of the anti-vibration springs 4 are provided with sealing baffles 42, which together with the retaining portion 2 form a closed oil storage space.

[0026] When the bearing speed changes, the impact force generated by the ball 60 acts on the anti-vibration spring 4, and the energy is absorbed by the deformation of the spring, effectively reducing the vibration transmission. The oil storage chamber 5 replenishes the lubricating grease through the oil inlet 21, and the oil outlet 41 ensures that the lubricating grease evenly covers the surface of the ball 60, eliminating the lubrication blind area. The anti-vibration spring 4 produces a pumping effect when it is deformed, which prompts the lubricating grease to quickly seep out to form a dynamic oil film, reducing friction and wear.

[0027] Reference Figure 1 and Figure 2 The annular frame 1 is located in the oil storage chamber 5 and is relatively provided with V-shaped folding spring pieces 6. The openings of the two folding spring pieces 6 are arranged facing each other. One end of the folding spring piece 6 is connected to the anti-vibration spring piece 4, and the other end is connected to the inner wall of the retaining portion 2. The oil inlet 21 and the oil outlet 41 are both located in the enclosed area of ​​the two folding spring pieces 6. The two folding spring pieces 6 and the upper and lower sealing baffles 42 are arranged to enclose the above-mentioned oil storage chamber 5.

[0028] The folding spring piece 6 provides secondary buffer support, maintains structural stability under normal loads, and achieves energy dissipation by cooperative deformation under impact loads. During the deformation process, the folding spring piece 6 generates an extrusion movement, which cooperates with the bending of the anti-vibration spring piece 4 to form a composite oil pumping effect, thereby improving the efficiency of lubricating grease delivery. Under normal circumstances, the folding spring piece 6 supports the anti-vibration spring piece 4. When the bearing rotates, the ball 60 will always generate a certain impact force on the cage, thereby driving the cage to rotate synchronously. If the anti-vibration spring piece 4 is easily deformed, the ball 60 will vibrate back and forth in the cage, which will affect the use of the bearing. Therefore, the anti-vibration spring piece 4 is supported by the folding spring piece 6, so that the anti-vibration spring piece 4 will only deform to reduce the impact when it is impacted by a large impact force.

[0029] The implementation principle of a retaining frame in an embodiment of the present application is as follows: the bearing in the present application is relatively large in size and is mainly used in the field of wind power generation; the ball 60 is constrained between the anti-vibration springs 4, and the impact kinetic energy generated by the ball 60 acts on the anti-vibration springs 4 when the rotation speed suddenly changes, and energy absorption is achieved through elastic deformation, thereby effectively reducing vibration transmission; the oil storage chamber 5 is replenished with lubricating grease through the oil inlet 21, and the porous oil outlet 41 ensures that the lubricating grease evenly covers the surface of the ball 60, eliminating lubrication blind spots; when the impact force causes the anti-vibration spring 4 to deform, the volume change of the oil storage chamber 5 produces a pumping effect, which prompts the lubricating grease to quickly seep out to form a dynamic oil film, thereby forming effective isolation at the friction interface, and simultaneously achieving impact buffering and friction optimization, thereby helping to increase the service life of the bearing.

[0030] Example 2 Reference Figure 3The difference between this embodiment and embodiment 1 is that the bottom of the anti-vibration spring sheet 4 extends to form a fluid disturbance wing sheet 7, and the end of the disturbance wing sheet 7 is bent to form a smoothing sheet 9. Figure 4 , and the smearing sheet 9 is arranged at an angle, which can better guide the lubricating grease to enter under the smearing sheet 9.

[0031] The technical effect of this optimization scheme is that during the rotation of the bearing, the disturbance wing 7 produces a shearing effect on the lubricating grease in the bearing raceway, and the smearing blade 9 simultaneously adjusts the thickness of the lubricating grease. The dynamic disturbance effect not only improves the uniformity of the lubricating grease distribution, but also enhances the heat dissipation efficiency through the conversion of fluid kinetic energy, forming active lubrication.

[0032] Example 3 Reference Figure 5 The difference between this embodiment and the second embodiment is that the smearing pieces 9 of the two same-side disturbance wings 7 are both formed with a receiving piece 10 on the side close to each other, and the receiving piece 10 and the smearing piece 9 are arranged obliquely and are arranged in a triangular shape. The smearing piece 9 and the receiving piece 10 are arranged in a triangular shape. When the bearing rotates, the smearing piece 9 and the receiving piece 10 rotate with the cage, and the rotation speed of the bearing and the cage are not the same. Therefore, when the smearing piece 9 and the receiving piece 10 rotate, the lubricating grease in the raceway of the inner ring 40 will be evenly stirred, and the shape of the lubricating grease will be modified. The shape of the lubricating grease will be adapted to the triangular shape surrounded by the smearing piece 9 and the receiving piece 10, and then the bottom sides of the ball 60 can contact with the lubricating grease, thereby improving the lubrication effect on the ball 60.

[0033] The triangular guide structure generates a pressure gradient during the rotation process, guiding the grease to flow in a directional manner and forming a stable oil wedge. It has both oil storage and flow diversion functions, forming a double lubrication guarantee in the ball 60 contact area, reducing the risk of boundary friction.

[0034] Example 4 Reference Figure 6 The difference between this embodiment and embodiment 3 is that the lower side of the anti-vibration spring piece 4 is connected to the disturbance wing 7 through the flexible deformation piece 20, and the two disturbance wing pieces 7 on the same side are connected through the positioning pin 30. The disturbance wing 7 is provided with a plug-in hole 71 for plugging with the positioning pin 30, and the aperture of the plug-in hole 71 is larger than the diameter of the positioning pin 30.

[0035] When the anti-vibration spring sheet 4 is deformed under the impact load, the flexible deformation sheet 20 allows the disturbance wing 7 to produce adaptive deflection, and the clearance fit design of the positioning pin 30 and the plug hole 71 forms a controllable kinematic pair, so that the disturbance wing 7 produces coordinated deformation and changes the distribution pattern of the lubricant. Specifically, when the disturbance wing 7 is bent, it will drive the receiving sheet 10 to rotate, and the ends of the two receiving sheets 10 that are close to each other will have a certain displacement in the vertical direction, and the smoothing sheet 9 will rotate, which will cause the lubricating grease to move toward the receiving sheet 10, so that the lubricating grease will accumulate partially between the two receiving sheets 10. The dynamic adjustment mechanism promotes the lubricant to enrich the contact area when the impact occurs, forming a transient supercharged lubrication effect, and the lubricating grease can also buffer the ball 60, which can timely and effectively reduce the friction between the ball 60 and the anti-vibration spring sheet 4.

[0036] Reference Figure 7 and Figure 8 The embodiment of the present application discloses a rolling bearing, including an inner ring 40, an outer ring 50, a cage and a ball 60, wherein the cage is the cage in any of the above embodiments.

[0037] A sealing ring 70 is arranged between the inner ring 40 and the outer ring 50, and an arc-shaped spring piece 80 is arranged inside the sealing ring 70. The sealing ring 70 and the arc-shaped spring piece 80 are compounded by a packaging process; the center of curvature of the arc-shaped spring piece 80 is located on the side away from the bearing, a first abutment groove 501 is formed on the inner side of the outer ring 50, and a second abutment groove 401 is formed on the outer side of the inner ring 40, and both ends of the sealing ring 70 are plugged into the first abutment groove 501 and the second abutment groove 401.

[0038] When installing the sealing ring 70, firstly, apply appropriate bending force to the sealing ring 70 along its natural bending direction to increase its curvature, and then accurately embed it into the gap between the inner ring 40 and the outer ring 50. By gradually advancing, ensure that the upper and lower ends of the sealing ring 70 are accurately inserted into the first abutting groove 501 of the outer ring 50 and the second abutting groove 401 of the inner ring 40, respectively, so that the sealing ring 70 is firmly installed and fixed.

[0039] The outer edge of the outer ring 50 is formed with a first guide portion 502, the outer edge of the inner ring 40 is formed with an annular spring sheet 90, a second guide portion 901 is formed on the annular spring sheet 90, the first guide portion 502 and the second guide portion 901 are arranged opposite to each other, an abutment portion 902 is formed on the annular spring sheet 90, and the abutment portion 902 serves as an inner wall of one side of the second abutment groove 401. In addition, the inner ring 40 is provided with an avoidance groove 402 on the bottom wall of the second abutment groove 401 to avoid the movement of the abutment portion 902.

[0040] During the actual installation of the sealing ring 70, the sealing ring 70 is guided by the first guide portion 502 of the outer ring 50 and the second guide portion 901 of the inner ring 40 to move inward. During this process, the arc-shaped spring piece 80 compresses the annular spring piece 90, thereby providing sufficient installation space for the sealing ring 70, so that it can quickly slide into the first abutment groove 501 and the second abutment groove 401. After the installation is completed, the annular spring piece 90 returns to its original state, forming a limiting effect on the sealing ring 70 to ensure its stability.

[0041] When removing the sealing ring 70, a flat sheet tool is used to press down the annular spring sheet 90 to deform it to the bottom of the sealing ring 70. At this time, the tool is in contact with the sealing ring 70, and because the sealing ring 70 loses the contact of the abutment portion 902 of the annular spring sheet 90, the sealing ring 70 tends to move outward, which facilitates the insertion of the tool into the sealing ring 70. By rotating the tool around the annular spring sheet 90 for one circle, the sealing ring 70 can be separated from the abutment portion 902 of the annular spring sheet 90, and the removal is completed. This design makes the installation and removal operations of the sealing ring 70 more efficient and convenient, and significantly improves the maintenance efficiency.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
