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] A ball bearing is a type of rolling bearing. The ball is installed between the inner steel ring and the outer steel ring, can bear a large load, and the ball is positioned and held by a cage.

[0003] Currently, when the bearing is in use, the cage will bear the impact and vibration of the ball. When the bearing is applied to a scenario where the rotational speed is constantly changing, the cage needs to bear greater impact and vibration, resulting in a decrease in the service life of the bearing. Moreover, during this process, the friction between the cage and the ball will also increase, which will also lead to a decrease in the service life of the bearing. Summary of the Invention

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

[0005] The cage and the rolling bearing having the cage provided by the present application adopt the following technical solutions:

[0006] A cage includes two oppositely arranged annular frames. An arc-shaped holding part is formed on the annular frame. After the two annular frames are connected, the corresponding holding parts enclose to form an annular constraint groove. Anti-vibration elastic sheets are arranged at both ends of the annular frame where the holding part is located. An oil storage chamber is formed between the anti-vibration elastic sheet and the holding part. An oil inlet communicating with the oil storage chamber is opened on the outer wall of the annular frame where the holding part is located. A plurality of oil outlets communicating with the oil storage chamber are opened on the anti-vibration elastic sheet; Sealing gaskets are arranged at the upper and lower edges of the anti-vibration elastic sheet, and together with the holding part, they form a closed oil storage space.

[0007] By adopting the above technical solution, the ball is located between the two annular bracket holding parts and between the anti-vibration elastic sheets. When the rotation speed of the bearing changes, the rotation speed of the ball also changes. Therefore, the impact force between the ball and the cage will increase, and the impact force will act on the anti-vibration elastic sheet, causing the anti-vibration elastic sheet to deform to a certain extent, thereby unloading the impact force, that is, buffering and damping the ball and the cage, which helps to improve the service life of the bearing; in addition, lubricating grease can be timely supplemented into the oil storage chamber from the oil inlet, and the lubricating grease can be discharged from the oil outlet and lubricate the outer wall of the ball, so as to ensure that there is no dead angle in the lubrication of the ball and prevent excessive friction between the ball and the inner wall of the holding part; when the ball impacts the anti-vibration elastic sheet and drives the anti-vibration elastic sheet to deform, the anti-vibration elastic sheet will squeeze the grease in the oil storage chamber, generating a pumping effect. At this time, the grease will be discharged from the oil outlet, and the grease will quickly adhere to the periphery of the ball. When the ball impacts the anti-vibration elastic sheet, the friction force between the two will increase. By discharging the grease, the friction force between the ball and the anti-vibration elastic sheet can be reduced, preventing excessive friction force from causing wear or generating excessive heat on the ball, thereby further improving the service life of the bearing.

[0008] Preferably, the annular frame is provided with V-shaped folded elastic sheets oppositely arranged in the oil storage chamber. The openings of the two folded elastic sheets face each other. One end of the folded elastic sheet is connected to the anti-vibration elastic sheet, and the other end of the folded elastic sheet is connected to the inner wall of the holding part.

[0009] By adopting the above technical solution, the folded elastic sheet plays a supporting role for the anti-vibration elastic sheet. Since the ball will always generate a certain impact force on the cage when the bearing rotates, driving the cage to rotate synchronously. If the anti-vibration elastic sheet deforms easily, the ball will vibrate reciprocally in the cage, which will instead affect the use of the bearing. Therefore, the folded elastic sheet supports the anti-vibration elastic sheet, so that the anti-vibration elastic sheet will deform to reduce the impact only when it is impacted by a large impact force; when the anti-vibration elastic sheet deforms, the folded elastic sheet will also deform. Since the oil storage chamber contains lubricating grease, the two folded elastic sheets will squeeze and convey the lubricating grease towards the middle, and then cooperate with the bending of the anti-vibration elastic sheet to squeeze the grease, which can ensure that the lubricating grease can be discharged smoothly and quickly from the oil outlet.

[0010] Preferably, a disturbance wing is extended at the bottom of the anti-vibration elastic sheet, and a smoothing sheet is bent at the bottom of the disturbance wing.

[0011] By adopting the above technical solution, when the bearing rotates, the disturbance wing will rotate synchronously with the cage. The smoothing sheet of the disturbance wing will smooth the lubricating grease in the inner ring raceway of the bearing, thereby ensuring that the rolling of the ball is smoother and more fluent; and when the cage rotates, the disturbance wing can also stir the lubricating grease to improve the fluidity of the lubricating grease.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] 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.

[0016] A rolling bearing comprises an inner ring, an outer ring, a cage and balls, wherein the cage is the cage mentioned above.

[0017] 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.

[0018] 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.

[0019] Preferably, a first guiding portion is formed on the outer edge of the outer ring, an annular elastic piece is formed on the outer edge of the inner ring, a second guiding portion is formed on the annular elastic piece, the first guiding portion and the second guiding portion are arranged oppositely, and an abutting portion is formed on the annular elastic piece, and the abutting portion serves as an inner wall on one side of the second abutting groove.

[0020] By adopting the above technical solution, during the actual installation process of the sealing ring, the sealing ring moves inward along the first guiding portion and the second guiding portion, and under the action of the arc-shaped elastic piece, the annular elastic piece will deform, thereby facilitating the sealing ring to quickly enter the first abutting groove and the second abutting groove. Then, the annular elastic piece resets to limit the sealing ring; during disassembly, a flat sheet-like tool is used to press down the annular elastic piece. When the annular elastic piece is pressed down to the bottom of the sealing ring, at this time, the sheet-like tool contacts the sealing ring, and the sealing ring will move 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 elastic piece for one week to smoothly remove the sealing ring; the installation structure of this sealing ring can make the disassembly and assembly of the sealing ring more rapid and convenient.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. The ball bearings are constrained between the anti-vibration elastic pieces. When the rotational speed suddenly changes, the impact kinetic energy generated by the ball bearings acts on the anti-vibration elastic pieces, and energy absorption is achieved through elastic deformation, effectively reducing vibration transmission. The oil storage chamber replenishes lubricating grease through the oil inlet, and the porous oil outlet ensures that the lubricating grease evenly covers the surface of the ball bearings, eliminating lubrication blind spots. When the impact force causes the anti-vibration elastic pieces to deform, the volume change of the oil storage chamber generates a pumping effect, prompting the lubricating grease to quickly seep out to form a dynamic oil film, forming an effective isolation at the friction interface, and simultaneously achieving impact buffering and friction optimization;

[0023] 2. During the rotation of the bearing, the disturbing fins shear the lubricating grease in the bearing raceway, and the spreading fins simultaneously adjust the oil film thickness. The dynamic disturbing effect not only improves the uniformity of the lubricating grease distribution, but also enhances the heat dissipation efficiency by converting the fluid kinetic energy, forming an active lubrication;

[0024] 3. When the anti-vibration elastic pieces deform under the action of an impact load, the flexible deformation piece allows the disturbing fins to generate an adaptive deflection, thereby changing the distribution form of the lubricating grease. This dynamic adjustment mechanism can prompt the lubricating grease to concentrate towards the contact area when an impact occurs, forming a transient pressurized lubrication effect, and can also buffer the movement of the ball bearings;

[0025] 4. Under the action of the first guiding portion and the second guiding portion, the installation efficiency of the sealing ring is significantly improved. During disassembly, the sealing ring can be quickly disassembled by pressing down the annular elastic piece with a special tool, greatly simplifying the maintenance operation process.

Detailed implementation manners

[0035] The following further describes this application in detail with reference to the attached Figure 1 - attached Figure 8 drawings.

[0036] The embodiments of this application disclose a cage.

[0037] Embodiment 1

[0038] Referring to Figure 1, the cage includes two oppositely arranged annular frames 1, which are fixedly connected by pins. An arc-shaped holding part 2 is formed on the annular frame 1. After the two annular frames 1 are connected, the corresponding holding parts 2 enclose a ring-shaped constraint groove 3 to position and hold the ball bearings 60. Anti-vibration elastic sheets 4 are integrated at both ends of the holding part 2 of the annular frame 1. An oil storage chamber 5 is formed between the anti-vibration elastic sheet 4 and the holding part 2. An oil inlet 21 communicating with the oil storage chamber 5 is provided on the outer wall of the annular frame 1 at the holding part 2. A plurality of oil outlets 41 are provided on the anti-vibration elastic sheet 4, and the oil outlets 41 communicate with the oil storage chamber 5. Sealing gaskets 42 are provided at the upper and lower edges of the anti-vibration elastic sheet 4, and together with the holding part 2, they form a closed oil storage space.

[0039] When the rotational speed of the bearing changes, the impact force generated by the ball bearings 60 acts on the anti-vibration elastic sheet 4, and energy absorption is achieved through the deformation of the elastic sheet, effectively reducing vibration transmission. The oil storage chamber 5 is replenished with lubricating grease through the oil inlet 21, and the oil outlets 41 ensure that the lubricating grease evenly covers the surface of the ball bearings 60, eliminating lubrication blind spots. When the anti-vibration elastic sheet 4 deforms, a pumping effect is generated, prompting the lubricating grease to quickly seep out to form a dynamic oil film, reducing friction and wear.

[0040] Refer to Figure 1 and Figure 2 , V-shaped folded elastic sheets 6 are oppositely arranged in the oil storage chamber 5 of the annular frame 1. The openings of the two folded elastic sheets 6 face each other. One end of the folded elastic sheet 6 is connected to the anti-vibration elastic sheet 4, and the other end is connected to the inner wall of the holding part 2. The oil inlet 21 and the oil outlets 41 are both located within the enclosed area of the two folded elastic sheets 6. The two folded elastic sheets 6 and the upper and lower sealing gaskets 42 enclose and form the above-mentioned oil storage chamber 5.

[0041] The folded elastic sheets 6 provide secondary buffer support, maintaining structural stability under normal loads and dissipating energy through coordinated deformation under impact loads. During the deformation process, the folded elastic sheets 6 generate extrusion movements, cooperating with the bending of the anti-vibration elastic sheet 4 to form a composite oil pumping effect, improving the conveying efficiency of the lubricating grease. Under normal circumstances, the folded elastic sheets 6 support the anti-vibration elastic sheet 4. Since the ball bearings 60 will always generate a certain impact force on the cage during the rotation of the bearing, which will drive the cage to rotate synchronously. If the anti-vibration elastic sheet 4 deforms easily, the ball bearings 60 will vibrate reciprocally within the cage, which will instead affect the use of the bearing. Therefore, the folded elastic sheets 6 support the anti-vibration elastic sheet 4, so that the anti-vibration elastic sheet 4 will only deform to reduce the impact when it is impacted by a relatively large impact force.

[0042] 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.

[0043] Example 2

[0044] Reference Figure 3 The 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.

[0045] 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.

[0046] Example 3

[0047] 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.

[0048] 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.

[0049] Example 4

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] The outer edge of the outer ring 50 is formed with a first guiding portion 502, the outer edge of the inner ring 40 is formed with an annular elastic piece 90, a second guiding portion 901 is formed on the annular elastic piece 90, the first guiding portion 502 and the second guiding portion 901 are arranged oppositely, a butting portion 902 is formed on the annular elastic piece 90, and the butting portion 902 serves as an inner wall on one side of the second butting groove 401. And an avoidance groove 402 is further formed on the bottom wall of the second butting groove 401 where the inner ring 40 is located for avoiding the movement of the butting portion 902.

[0056] During the actual installation process of the sealing ring 70, the sealing ring 70 is guided by the first guiding portion 502 of the outer ring 50 and the second guiding portion 901 of the inner ring 40 and moves inward. During this process, the arc-shaped elastic piece 80 compresses the annular elastic piece 90, thereby providing sufficient installation space for the sealing ring 70 to enable it to quickly slide into the first butting groove 501 and the second butting groove 401. After the installation is completed, the annular elastic piece 90 returns to its original state and forms a limiting effect on the sealing ring 70 to ensure its stability.

[0057] When disassembling the sealing ring 70, a flat sheet-like tool is used to press down the annular elastic piece 90 to deform it to the bottom position of the sealing ring 70. At this time, the tool contacts the sealing ring 70, and since the sealing ring 70 loses the butting of the butting portion 902 of the annular elastic piece 90, the sealing ring 70 has a tendency to move outward, facilitating the insertion of the tool into the sealing ring 70. By rotating the tool around the annular elastic piece 90 for one week, the sealing ring 70 can be separated from the butting portion 902 of the annular elastic piece 90 to complete the disassembly. This design makes the installation and disassembly operations of the sealing ring 70 more efficient and convenient, significantly improving the maintenance efficiency.

[0058] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
