Description

Technical Field

[0001] This invention relates to the field of bearing processing technology, specifically to a self-aligning roller bearing, assembly equipment, and assembly method. Background Technology

[0002] Self-aligning roller bearings are typically used in equipment with heavy loads, such as continuous casting machines or presses. These bearings must withstand both lateral and longitudinal loads. Therefore, the inner surface of the outer ring of a self-aligning roller bearing is usually arc-shaped. When the bearing rollers are under both longitudinal and lateral loads and tilt, they can roll normally on the arc surface. Due to the large load and slow rolling speed of the equipment, these bearings are much larger and heavier than ordinary bearings. Because of their large size, weight, and low usage, self-aligning roller bearings are usually installed manually, and in some cases, even by hammering. Manual installation is extremely slow and has a high failure rate. Summary of the Invention

A bracket is mounted on the slide seat of the first slide rail. Fixing members are symmetrically arranged at the ends of the brackets. An outer ring is mounted on the fixing member, and an inner ring and a retainer are vertically arranged inside the outer ring. A hollow groove is formed in the middle of the limiting frame, and a roller is rotatably connected within the groove. The roller and the outer central ring of the retainer are tangentially frictional. The two slide seats of the second slide rails... Each housing is fixed with a circular shell, and a material tray is rotatably connected inside each shell. Multiple first material holes are provided at the edge of each material tray. A first motor is fixed to the outside of each shell, and the first motor is connected to the corresponding material tray. A feeding hole is opened on the side of each shell away from each other. The feeding hole and one of the first material holes are coaxial. The projections of the circles containing the shell and the circles containing the retainer intersect. A feeding gun head is fixed to the side of each shell close to each other. One end of the feeding gun head is directly opposite one of the mounting slots on the retainer. A distance sensor is fixed to the side of each shell close to each other. The distance sensor is directly opposite the positioning hole in one of the mounting slots on the side of the feeding gun head.

[0007] The feeding gun head is directly opposite one of the first material holes. An electric push rod is fixed to the outside of the housing. A push plate is fixed to the electric push rod. The push plate is used to insert into any one of the first material holes. The push plate and the feeding gun head are coaxial. Rollers are provided in each of the first material holes.

[0008] The outer side of the center of the material tray is provided with a ring of holes. The outer side of the housing is provided with an arc-shaped groove. A slider slides in each groove. A lever is fixed on each slider. One end of the lever is connected to a ratchet by a torsion spring. The ratchet engages in one of the holes of the corresponding material tray.

[0009] The limiting frame is provided with a positioning pin, which engages with the positioning groove. The middle part of the arc surface of the mounting position and the inner edge of the feeding gun head are tangent at the same point.

[0010] Preferably, each of the fixing members has a limit rod fixed to its inner side, a limit sleeve slidably disposed on each limit rod, a fixing plate fixed to the inner side of each limit sleeve, the fixing plate being slidably disposed in a sealed manner on the inner side of the fixing member, a spring fixed inside each limit sleeve, and the other end of the spring being fixed to the limit rod.

[0011] Preferably, the sides of the fasteners that are far apart from each other are all attached to the inner side of the outer ring, and the fixing plates on the inner side of the fasteners are all used to fix the inner ring.

[0012] Preferably, the interior of the fixing member and the bracket are hollow and interconnected, and the bracket is equipped with a bidirectional air pump, which is fixed on the slide of the first slide rail.

[0013] Preferably, a rubber ring for increasing friction is provided on the outer side of the roller, a sprocket is fixed on one side of the roller, a second motor is fixed at the bottom of the frame, a sprocket is fixed at the drive end of the second motor, and the sprocket on the second motor and the sprocket on the roller are connected by a chain.

[0014] Preferably, the feeding gun head has multiple grooves at one end near the mounting groove.

[0015] Preferably, a method for assembling a self-aligning roller bearing includes the following steps:

[0016] Step S1, Bearing Installation: Place the cage on the inner ring, then insert the inner ring vertically into the outer ring. Next, place the outer ring on the fixing piece. The first slide rail moves the bracket through the fixing piece to move the outer ring to the end of the limit frame. Then, manually rotate the inner ring to engage the positioning pin and the positioning groove. At this point, the installation position and the corresponding feeding gun head position are completed. The roller and the center ring are tangentially abutting. The air pump inflates the fixing piece through the bracket to fix the inner ring with the fixing plate. The bearing installation is complete.

[0017] Step S2, Roller Installation: Install the roller body through the feeding hole into each corresponding first material hole. When the lever is turned, the ratchet is engaged in the turning hole, which pushes the material tray to rotate in the housing. When the lever is reset, the ratchet does not move the material tray because of the rotation of the torsion spring, so that the material tray rotates in one direction. One roller body is installed from the feeding hole into the first material hole with each turn of the lever until each first material hole is equipped with a roller body.

[0018] Step S3, Position Adjustment: The second motor drives the roller to rotate the center ring on the inner ring via the chain and sprocket. The distance sensor always measures the distance to the side of the cage. The positioning hole is furthest from the distance sensor. When the distance sensor measures the maximum value of the cage, the second motor stops working.

[0019] Step S4, Assembly Installation: The slide block of the second slide rail brings the feeding gun head close to the mounting groove through the housing. Then, the electric push rod pushes the roller in the corresponding first material hole into the mounting groove through the push plate. After completing one roller installation, the first motor drives the material tray to rotate in the housing so that the roller in the next first material hole is aligned with the feeding gun head. At the same time, the second motor drives the roller to rotate the cage through the chain and sprocket. After the distance sensor displays the maximum distance, it stops. Repeat the installation of rollers until the cage roller installation is completed. Then remove the bearing and rotate the inner ring to complete the bearing assembly.

[0020] This invention provides a self-aligning roller bearing, a bushing assembly device, and a bushing assembly method. It has the following beneficial effects:

[0021] This invention utilizes a self-aligning roller bearing with a central ring and positioning groove in conjunction with a fitting device. By combining the fitting device with the self-aligning roller bearing, the roller body can be mechanically and automatically installed during bearing assembly, resulting in high efficiency, high yield, rapid bearing assembly, and reduced labor costs.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1:

[0036] like Figures 1-11 As shown, this embodiment of the invention provides a assemblies for self-aligning roller bearings.

[0037] The self-aligning roller bearing includes an inner ring 2, an outer ring 1, and a cage 4. The inner ring 2 is located inside the outer ring 1. The cage 4 is assembled between the inner ring 2 and the outer ring 1. A center ring 7 is provided in the middle of the cage 4. Alternating mounting grooves 5 are provided on both sides of the cage 4. A positioning hole 6 is provided in the middle of the side where the mounting grooves 5 are close to each other. A mounting position 8 is provided on the side of the inner ring 2. A positioning groove 40 is provided on the inner ring 2. Two sets of raceways are provided on the outer side of the inner ring 2 for the rolling of the rollers 3. A complete circular arc raceway is provided inside the outer ring 1. When the bearing is subjected to pressure perpendicular to the bearing… When the roller 3 rolls in the arc raceway, it will not damage the bearing housing, ensuring the high load and life of the bearing housing. The positioning hole 6 is used for distance measurement and positioning when installing the roller 3, so as to achieve the accuracy of the roller 3 installation and ensure that the roller 3 and the mounting groove 5 have a strong and efficient fit, and will not interfere with each other, which would make it difficult to install the roller 3 using a set of equipment, thus achieving stable bearing installation quality. The positioning groove 40 is used for the fixed fit between the inner ring 2 and the limit bracket 21. When installing the roller 3, the mounting position 8 gives the roller 3 some room, so that the roller can fully enter the cage 4.

[0038] The assembly of self-aligning roller bearings includes a frame 9 and a limiting frame 21 mounted on the top of the frame 9. A second slide rail 14 is symmetrically arranged on the top of the frame 9, and a first slide rail 10 is also mounted on the top of the frame 9. The first slide rail 10 is located at one end of the limiting frame 21 along the same straight line. The second slide rails 14 are located on both sides of the limiting frame 21 away from the first slide rail 10. A bracket 12 is mounted on the slide seat of the first slide rail 10. Fixing members 13 are symmetrically arranged at the ends of the brackets 12. An outer ring 1 is mounted on the fixing member 13. An inner ring 2 and a retainer 4 are vertically arranged inside the outer ring 1. The second slide rails 14 provide housings 19 on both sides to accommodate the retainer 4. The bearing rollers 3 on the upper can be installed simultaneously, achieving efficient and mechanized automatic installation. This results in good bearing assembly and fast speed. The center of the limiting frame 21 has a hollow groove with a roller 23 rotatably connected inside. The roller 23 and the center ring 7 on the outer side of the retainer 4 are tangentially frictional. Circular housings 19 are fixed on the slides of the two second slide rails 14. Material trays 28 are rotatably connected inside each housing 19. Multiple first material holes 29 are provided at the edge of the material trays 28. First motors 16 are fixed on the outer side of each housing 19, and each first motor 16 is connected to the corresponding material tray 28. The housings 19 have openings on the side furthest from each other. There is a feeding hole 18, which is coaxial with one of the first feeding holes 29. The projections of the circles containing the housing 19 and the circles containing the cage 4 intersect. Feeding gun heads 22 are fixed on the adjacent sides of the housing 19. One end of the feeding gun head 22 is directly opposite one of the mounting slots 5 on the cage 4. Distance sensors 27 are fixed on the adjacent sides of the housing 19. The distance sensors 27 are directly opposite the positioning hole 6 in one of the mounting slots 5 on the side of the feeding gun head 22. The distance sensors 27 and the motor are connected by a microcontroller to realize the overall operation of the equipment. Here, the distance sensors 27 will measure three distances, one of which is the distance sensor 29. The distance between 7 and the outer side of the cage 4 is: 2. The distance between the distance sensor 27 and the mounting groove 5 is: 3. The distance between the distance sensor 27 and the positioning hole 6 is the longest, indicating that the distance sensor 27 is located at the center of the positioning hole 6. At this time, the distance sensor 27 is set on one side of the feeding gun head 22, corresponding to the adjacent mounting groove 5. Therefore, the end of the feeding gun head 22 is directly facing the mounting position 8 and the mounting groove 5. At this time, when the roller body 3 is discharged, it can directly enter the mounting groove 5. The two ends of the roller body 3 are arc-shaped, so the two ends of the roller body 3 enter the mounting groove 5 relatively smoothly.

[0039] Limiting rods 33 are fixed to the inner side of the fixing member 13. Limiting sleeves 35 are slidably provided on the limiting rods 33. Fixing plates 36 are fixed to the inner side of the limiting sleeves 35. The fixing plates 36 are slidably and sealed on the inner side of the fixing member 13. Springs 34 are fixed inside the limiting sleeves 35. The other end of the springs 34 is fixed to the limiting rods 33. The fixing plates 36 are used to fix the inner ring 2 so that the outer ring 1 and the inner ring 2 are stationary. When the roller body 3 is installed later, it can be ensured that the cage 4 can rotate on the inner ring 2 without restriction.

[0040] The sides of the fasteners 13 that are far apart from each other are attached to the inner side of the outer ring 1, and the fixing plates 36 on the inner side of the fasteners 13 are used to fix the inner ring 2.

[0041] Both the fixing member 13 and the bracket 12 are hollow and interconnected. The bracket 12 is equipped with a bidirectional air pump 11. The air pump 11 is fixed on the slide of the first slide rail 10. The air pump 11 is used to push the fixing plate 36 to fix the inner ring, so as to release the inner ring 2 or fix the inner ring 2.

[0042] A rubber ring for increasing friction is provided on the outer side of the roller 23. A sprocket 24 is fixed on one side of the roller 23. A second motor 26 is fixed at the bottom of the frame 9. The drive end of the second motor 26 is fixed with a sprocket 24, and the sprocket 24 on the second motor 26 and the sprocket 24 on the roller 23 are connected by a chain 25.

[0043] The feeding gun head 22 has multiple grooves 32 at one end near the mounting groove 5. When the roller body 3 is pushed out by the push plate 31, it can be unrestricted. When the feeding gun head 22 is smaller than the mounting groove 5, there will be no movement interference, which facilitates material discharge.

[0044] The feeding gun head 22 is directly opposite one of the first material holes 29. An electric push rod 15 is fixed on the outside of the housing 19. The electric push rod 15 is fixed with a push plate 31. The push plate 31 is used to insert into any one of the first material holes 29. The push plate 31 and the feeding gun head 22 are coaxial. Roller bodies 3 are provided in each of the first material holes 29.

[0045] The outer side of the center of the tray 28 is provided with a ring of holes 30. The outer side of the housing 19 is provided with an arc-shaped groove 17. The slider 37 slides in the groove 17. The slider 37 is fixed with a lever 20. One end of the lever 20 is connected to a ratchet 38 through a torsion spring. The ratchet 38 is engaged in one of the holes 30 of the corresponding tray 28. One side of the ratchet 38 is limited by the lever 21, and the other side can be pushed by the tray 28. Therefore, the lever 20 can rotate the tray 28 in one direction. When the tray 28 is driven to rotate by the first motor 16, it will not interfere with the ratchet 38, which is similar to the same principle as the ratchet of an automatic car.

[0046] The limiting frame 21 is equipped with a positioning pin 39, which engages with the positioning groove 40. The middle part of the arc surface of the mounting position 8 and the inner edge of the feeding gun head 22 are tangent to the same point, which facilitates material discharge.

[0047] Example 2:

[0048] Reference Figures 1-11 As shown, this embodiment of the invention provides a method for assembling a self-aligning roller bearing. The equipment used for assembling the self-aligning roller bearing is the assembly equipment described above, and the method includes the following steps:

[0049] Step S1, Bearing Installation: Place the retainer 4 on the inner ring 2, then insert the inner ring 2 vertically into the outer ring 1. Next, place the outer ring 1 on the fixing member 13. The first slide rail 10 moves the bracket 12 through the fixing member 13 to move the outer ring 1 to the end of the limiting bracket 21. Then, manually rotate the inner ring 2 to make the positioning pin 39 and the positioning groove 40 engage. At this time, the installation position 8 and the corresponding feeding gun head 22 are installed. At this time, the roller 23 and the center ring 7 are tangentially abutted. The air pump 11 inflates the fixing member 13 through the bracket 12 to fix the inner ring 2 with the fixing plate 36. The bearing installation is complete.

[0050] Step S2, Roller Installation: Install the roller body 3 into each corresponding first material hole 29 through the feeding hole 18. When the lever 20 is turned so that the ratchet 38 is engaged in the turning hole 30, it pushes the material tray 28 to rotate in the housing 19. When the lever 20 is reset, the ratchet 38 does not turn the material tray 28 because the torsion spring rotates, so that the material tray 28 rotates in one direction. Each turn of the lever 20 installs one roller body 3 from the feeding hole 18 into the first material hole 29 until each first material hole 29 is equipped with a roller body 3.

[0051] Step S3, Position Adjustment: The second motor 26 drives the roller 23 to drive the central ring 7 through the chain 25 and sprocket 24, causing the cage 4 to rotate on the inner ring 2. The distance sensor 27 always measures the side distance of the cage 4. The positioning hole 6 is furthest from the distance sensor 27. When the distance sensor 27 measures the maximum value of the cage 4, the second motor 26 stops working.

[0052] Step S4, Assembly Installation: The slide block of the second slide rail 14 moves the feeding gun head 22 close to the mounting groove 5 through the housing 19. Then, the electric push rod 15 pushes the roller 3 in the corresponding first material hole 29 into the mounting groove 5 through the push plate 31. After completing one installation of the roller 3, the first motor 16 drives the material tray 28 to rotate in the housing 19 so that the roller 3 in the next first material hole 29 is aligned with the feeding gun head 22. At the same time, the second motor 26 drives the roller 23 to rotate the cage 4 through the chain 25 and sprocket 24. After the distance sensor 27 displays the maximum distance, it stops. Repeat the installation of the roller 3 until the cage 4 and roller 3 are installed. Then remove the bearing and rotate the inner ring 2 to complete the bearing assembly.

When the lever (20) is reset, the ratchet (38) does not turn the material tray (28) because the torsion spring rotates, thus realizing the unidirectional rotation of the material tray (28). The lever (20) is turned once to install one roller body (3) from the loading hole (18) into the first material hole (29) until each first material hole (29) is equipped with a roller body (3). Step S3, Position Adjustment: The second motor (26) drives the roller (23) to drive the central ring (7) through the chain (25) and sprocket (24) to make the cage (4) rotate on the inner ring (2). The distance sensor (27) always measures the side distance of the cage (4). The positioning hole (6) is furthest from the distance sensor (27). When the distance sensor (27) measures the maximum distance from the cage (4), the second motor (26) stops working. Step S4, Assembly Installation: The slide block of the second slide rail (14) moves the loading gun head (22) close to the mounting groove (5) through the housing (19). Then, the electric push rod (15) pushes the roller (3) in the corresponding first material hole (29) into the mounting groove (5) through the push plate (31). After completing one roller (3) installation, the first motor (16) drives the material tray (28) to rotate in the housing (19) so that the roller (3) in the next first material hole (29) is facing the loading gun head (22). At the same time, the second motor (26) drives the roller (23) to rotate the cage (4) through the chain (25) and sprocket (24). After the distance sensor (27) displays the maximum distance, it stops. Repeat the installation of roller (3) until the cage (4) and roller (3) are installed. Then remove the bearing and rotate the inner ring (2) to complete the bearing assembly.
