Description

Technical Field

[0001] This application relates to the technical field of gear assembly, and in particular to a quick assembly device for gear transmission bearings. Background Technology

[0002] Bearings are a widely used key component, mainly used to support the rotating shafts of machinery, reduce friction, and extend the service life of machinery. Depending on the application, bearings can be divided into various types such as ball bearings, roller bearings, and sliding bearings. When installing bearings, ensuring the accuracy and efficiency of installation is crucial for maintaining the normal operation of mechanical equipment. Rapid assembly technology is a method that greatly improves installation efficiency while maintaining good precision, and it is widely used in automobile manufacturing, aerospace, heavy machinery and other fields.

[0003] For example, patent application CN106321667B discloses a non-destructive bearing rapid assembly device, including a base, a pressing plate, a turntable, a hydraulic cylinder, and a cage; an L-shaped support is mounted on one side of the base, and a turntable is mounted on the other side via a rotating shaft. A support is provided on the base between the two, and a support block is fixedly connected to the bottom of the turntable near the support. The pressing plate is hinged to the top of the support, and an inner ring placement rack is provided in the middle of the plate; a hydraulic cylinder is mounted on the L-shaped support above the pressing plate, and the bottom end of the piston rod 333 in the cylinder passes through the support. An outer ring placement groove is provided on the upper edge of the turntable.

[0004] While the existing technology has multiple installation stations, allowing for simultaneous assembly of bearings and placement of parts at other stations, significantly improving work efficiency through synchronous operation, it still has the following problems: First, the process connection is time-consuming and discontinuous. After assembly, manual or auxiliary mechanisms are required to remove and transfer parts, which cannot be connected with the main assembly process, disrupting the synchronous continuity of multiple stations, extending assembly time, and restricting further improvement in batch assembly efficiency.

[0005] Secondly, the lack of buffer positioning measures between the balls and the inner and outer rings during assembly makes them prone to scratches and dents due to collision and friction, affecting the accuracy and wear resistance of the balls, shortening the bearing life, and potentially causing abnormal noises during operation, thus reducing the pass rate.

[0006] Finally, lubrication is required separately after assembly, which takes up extra time, increases process complexity and cost, and the delayed lubrication cannot compensate for minor wear during assembly, affecting the quality of bearing assembly. Summary of the Invention

[0007] To solve the above-mentioned technical problems, this application provides a quick assembly device for gear transmission bearings, which adopts the following technical solution: A quick assembly device for gear transmission bearings includes a bottom frame, a conveyor belt on the bottom frame, storage slots for placing the inner and outer rings of the bearing on the conveyor belt, and an assembly mechanism installed on the bottom frame.

[0008] Two conveyor rollers that cooperate with the conveyor belt are provided above the bottom frame. The conveyor rollers are symmetrically arranged along the length of the bottom frame. Fixed frames that cooperate with each conveyor roller and are symmetrical along the width of the bottom frame are installed on the bottom frame. The conveyor rollers are rotatably mounted on the corresponding fixed frames through bearings.

[0009] The assembly mechanism includes a ring frame located above the bottom frame. The ring frame is mounted on the bottom frame via a support frame. Multiple evenly distributed movable blocks are slidably mounted on the ring frame, and telescopic columns are rotatably mounted on the movable blocks via bearings.

[0010] Preferably, the storage groove includes an outer groove for placing the outer ring of the bearing and an inner groove that is concentric with the outer groove for placing the inner ring of the bearing. A through section is provided between the outer groove and the inner groove to allow space for the inner ring of the bearing to be placed before the ball is placed, so as to make room for the ball to enter.

[0011] Preferably, the ring frame consists of an inner ring and an outer ring, and the ring frame is provided with a feeding section one, a correction and limiting section, a feeding section two, a bending section, a uniform distribution section, a feeding section and a return section in sequence along the length direction.

[0012] Preferably, a horizontal frame is symmetrically installed on the inner ring of the ring frame along the length direction. A drive shaft is rotatably installed on the horizontal frame via bearings. Pulleys are installed on both drive shafts. The two pulleys are connected by belt drive. An elastic telescopic rod corresponding to a moving block is installed on the belt. The telescopic end of the elastic telescopic rod is connected to the moving block.

[0013] Preferably, the spacing between adjacent moving blocks along the length of the ring frame is equal to the spacing between adjacent storage slots along the length of the conveyor belt, and the elastic telescopic rod can adaptively adjust the spacing between the moving blocks and the belt.

[0014] Preferably, the diameter of the telescopic column's telescopic section is much smaller than the inner diameter of the bearing's inner ring. The telescopic column between the feeding section and the bending section is located directly above the through section. The telescopic column can limit the bearing's inner ring in the correction and limiting section and drive the bearing's inner ring and outer ring to be coaxial in the bending section.

[0015] Preferably, the telescopic column has multiple inner top blocks circumferentially arranged at the bottom of the telescopic section, a through groove is opened inside the telescopic column, and a piston rod that can automatically reset is slidably arranged on the through groove. The piston rod can pump gas into the through groove to make the inner top blocks press against the inner ring of the bearing outward. An elastic element for piston rod reset is provided in the through groove.

[0016] Preferably, a guide plate is installed on the support frame, and a guide slope that cooperates with the piston rod is provided on one side of the guide plate near the feeding section, and the end of the guide plate away from the guide slope is located above the unloading section.

[0017] Preferably, a rack plate is provided at the evenly distributed section of the annular frame, the rack plate is mounted on the support frame by a support protrusion, and a gear that meshes with the rack plate is installed on the part of the telescopic column above the moving block.

[0018] Preferably, the conveyor belt is provided with a plurality of retractable elastic sheets in the gap between the inner and outer grooves. The elastic sheets can support the balls and can be locked by the inner ring of the bearing after being reset.

[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. This invention achieves automatic and continuous conveying and assembly of the inner and outer rings of the bearing by cooperating with the conveyor belt and the moving block on the ring frame. During the assembly process, the telescopic column completes the gripping, limiting and moving of the inner ring of the bearing, so that the ball filling, bearing inner ring resetting, ball even distribution and unloading processes are seamlessly connected without manual or additional driving force transfer. This not only effectively maintains the continuity of multi-station synchronous operation, but also greatly shortens the overall assembly time and significantly improves the batch assembly efficiency.

[0020] 2. During assembly, the telescopic column provides flexible internal support to the inner ring of the bearing through the inner top block, ensuring that the inner ring is stably confined within the through section. This ensures a uniform gap between the inner and outer rings of the bearing, providing buffer positioning space for the ball bearing to fill. At the same time, the elastic sheet provides temporary support for the ball bearing, preventing it from falling or shifting. These measures reduce the collision and friction between the ball bearing and the inner and outer rings, avoiding scratches or dents, ensuring the accuracy of the ball bearing and the service life of the bearing, and improving the product qualification rate.

[0021] 3. This invention directly inserts lubricated balls at the second loading section, integrating lubrication into the main assembly process. The balls, already lubricated, enter the bearing's inner and outer rings during the initial assembly phase, ensuring timely lubrication of the contact surfaces during subsequent distribution and rotation, compensating for minor wear during assembly. This eliminates the need for a separate lubrication step, reducing time and process complexity, improving assembly efficiency while ensuring bearing assembly quality. Attached Figure Description

[0032] The following is in conjunction with the appendix Figures 1 to 9 This application will be described in further detail.

[0033] This application discloses a rapid assembly device for gear transmission bearings. During the assembly process, the device completes the gripping, limiting, and moving of the bearing inner ring, so that the ball filling, bearing inner ring resetting, ball even distribution, and unloading processes are seamlessly connected. No manual or additional driving force is required for transportation. This not only effectively maintains the continuity of multi-station synchronous operation, but also greatly shortens the overall assembly time and significantly improves the efficiency of batch assembly.

[0034] Reference Figure 1 as well as Figure 2 A gear transmission bearing quick assembly device includes a bottom frame 1, a conveyor belt 2 on the bottom frame 1, a storage groove 21 for placing the inner and outer rings of the bearing on the conveyor belt 2, and an assembly mechanism 3 installed on the bottom frame 1.

[0035] Two conveyor rollers 4 that cooperate with the conveyor belt 2 are provided above the bottom frame 1, and the conveyor rollers 4 are symmetrically arranged along the length direction of the bottom frame 1. The bottom frame 1 is also equipped with a fixed frame 11 that cooperates with each conveyor roller 4 and is symmetrically arranged along the width direction of the bottom frame 1. The conveyor rollers 4 are rotatably mounted on the corresponding fixed frame 11 through bearings.

[0036] The storage groove 21 includes an outer groove 211 for placing the outer ring of the bearing and an inner groove 212 that is concentric with the outer groove 211 and is used for placing the inner ring of the bearing. A through section is provided between the outer groove 211 and the corresponding inner groove 212 to make room for the inner ring of the bearing before the ball is placed, so as to ensure that there is enough space between the inner and outer rings of the bearing so that the ball can enter between the inner and outer rings of the bearing.

[0037] The assembly mechanism 3 includes an annular frame 31 located above the bottom frame 1. The annular frame 31 is composed of an inner ring and an outer ring, and is mounted on the bottom frame 1 via a support frame 12. Along its length, the annular frame 31 is sequentially provided with a first feeding section 311, a correction and limiting section 312, a second feeding section 313, a bending section 314, a uniform distribution section 315, a discharge section 316, and a return section 317.

[0038] Multiple evenly distributed movable blocks 32 are slidably arranged on the ring frame 31 along its length direction. A telescopic column 33 is rotatably mounted on the movable block 32 through a bearing. When the telescopic column 33 is in the straightening and limiting section 312, it can limit the inner ring of the bearing inside the through section. When the telescopic column 33 is in the bending section 314, it can move the inner ring of the bearing to the inside of the inner ring and make the inner and outer rings of the bearing coaxial.

[0039] A horizontal frame 34 is symmetrically installed on the inner ring of the ring frame 31 along its length. A drive shaft 35 is rotatably installed on the horizontal frame 34 via bearings. A pulley 36 is installed on each of the two drive shafts 35, and the two pulleys 36 are connected by a belt drive. An elastic telescopic rod 37 corresponding to the moving block 32 is installed on the belt, and the telescopic end of the elastic telescopic rod 37 is connected to the moving block 32.

[0040] It should be noted that the distance between adjacent moving blocks 32 along the length of the ring frame 31 is equal to the distance between adjacent storage troughs 21 along the length of the conveyor belt 2, so as to ensure that the telescopic columns 33 on the moving blocks 32 correspond one-to-one with the storage troughs 21. Since the distance between the moving blocks 32 and the belt is different when they are located in the feeding section and the uniform distribution section 315, the elastic telescopic rod 37 can adaptively adjust the distance between the moving blocks 32 and the belt while moving the moving blocks 32.

[0041] In specific operation, the existing drive motor (not shown in the figure) is started to drive any one drive shaft 35 to rotate via belt drive. During the rotation of the drive shaft 35, it cooperates with another drive shaft 35 to drive the belt to move synchronously via pulley 36. During the belt movement, the moving block 32 is driven to move synchronously via telescopic rod. When the moving block 32 drives the telescopic column 33 to move to the upper material section 311, when the telescopic column 33 moves to the storage slot 21 corresponding to the upper material section 311, the telescopic end of the corresponding telescopic column 33 is quickly moved upward by external force (human push or cylinder push).

[0042] The diameter of the telescopic column 33 is much smaller than the inner diameter of the bearing inner ring. The telescopic column 33 between the loading section 311 and the bending section 314 is located directly above the through section. During this process, the inner and outer rings of the bearing are placed in the inner groove 212 and outer groove 211 of the corresponding storage groove 21, respectively. The telescopic column 33 continues to move along the length of the ring frame 31. When the corresponding telescopic column 33 moves above the inner and outer rings of the bearing, the telescopic section of the telescopic column 33 is released, and the telescopic end of the telescopic column 33 is inserted into the inner ring of the bearing. At this time, the telescopic column 33 limits the inner ring of the bearing to the inside of the through section, and there is a gap between the inner and outer rings of the bearing.

[0043] It should be noted that the moving speed of the moving block 32 is set in advance to ensure that it does not move at an abnormal speed during the above process, thus avoiding the possibility that the inner and outer rings of the bearing will be placed before the loading section 311 is completed.

[0044] Multiple inner top blocks 331 are arranged along the circumference of the bottom of the telescopic section of the telescopic column 33. A through groove 332 is opened inside the telescopic column 33. A piston rod 333 that can automatically reset is slidably arranged on the through groove 332. The piston rod 333 can pump gas into the through groove 332, so that the inner top blocks 331 have the tendency to move outward to apply external force to the inner ring of the bearing.

[0045] A support frame 12 is installed on the bottom frame 1, and a guide plate 13 is installed on the support frame 12. The guide plate 13 has a guide slope that cooperates with the piston rod 333 on the side near the feeding section 311. The end of the guide section away from the guide slope is located above the unloading section 316.

[0046] The through groove 332 is equipped with an elastic element (such as a telescopic spring, which is common knowledge and therefore not shown in the figure) for resetting the piston rod 333. In specific operation, when the corresponding telescopic column 33 is inserted into the corresponding bearing inner ring, the corresponding telescopic column 33 synchronously drives the inner and outer rings of the bearing to move. During this movement, the inner and outer rings of the bearing synchronously drive the conveyor belt 2 to move on the conveyor roller 4. When the inner and outer rings of the bearing move from the feeding section 311 to the correction and limiting section 312, the telescopic column 33 synchronously drives the piston rod 333 to move. When the top of the piston rod 333 abuts against the guide slope, the piston rod 333 moves downward due to the obstruction of the guide slope. During the downward movement of the piston rod 333, the gas inside the through groove 332 is compressed and expanded. The compression and expansion of the gas causes the top of the inner ring to have an outward movement tendency and provides internal support for the bearing inner ring, so that the bearing inner ring and the telescopic end of the telescopic column 33 remain temporarily relatively fixed.

[0047] When the piston rod 333 moves to the bottom of the guide plate 13, the piston rod 333 continues to move horizontally but remains relatively stationary in the vertical direction. At this time, the inner top block 331 continuously applies external force to the inner ring of the bearing, ensuring that the telescopic column 33 and the inner top block 331 cooperate to lock the inner ring of the bearing. The telescopic column 33 and the inner top block 331 cooperate to limit the inner ring of the bearing, ensuring that enough balls are left in the gap between the inner and outer rings of the bearing. When the inner and outer rings of the bearing move to the second feeding section 313, balls with lubricating oil on their surface are filled into the gap between the inner and outer rings of the bearing manually or by existing feeding equipment (not shown in the figure).

[0048] After loading, the moving block 32 synchronously drives the inner and outer rings of the bearing to move towards the bending section 314 via the telescopic column 33. When the moving block 32 passes through the bending section 314 and moves towards the evenly distributed section 315, the moving block 32 drives the inner ring of the bearing to move from the through section to the inner groove 212 via the telescopic column 33. When the moving block 32 leaves the bending section 314, the inner and outer rings of the bearing are coaxial, and the balls are distributed between the inner and outer rings of the bearing.

[0049] A rack plate 14 is provided at the evenly distributed section 315 of the ring frame 31, and the rack plate 14 is mounted on the support frame 12 through the support protrusion. A gear 15 that meshes with the rack plate 14 is installed on the circumferential surface of the telescopic column 33 above the moving block 32.

[0050] At this time, the moving block 32 drives the telescopic column 33 to move towards the evenly distributed section 315. During the movement of the moving block 32, the gear 15 on the corresponding telescopic column 33 meshes with the rack plate 14. The meshing of the rack plate 14 and the gear 15 drives the corresponding telescopic column 33 to rotate. During the rotation of the corresponding telescopic column 33, the inner ring of the corresponding bearing is synchronously driven to rotate through the inner top. During the rotation of the inner ring of the bearing, the balls can be evenly distributed, so that the balls can rotate freely between the inner and outer rings of the bearing. The bearing is now assembled.

[0051] The assembled bearing moves synchronously driven by the telescopic column 33. When the bearing leaves the conveyor belt 2, the telescopic column 33 and the inner top block 331 move downward to the material section 316. When the telescopic column 33 leaves the guide plate 13, the piston rod 333 resets under the action of the elastic element. The gas inside the through groove 332 is no longer compressed. The inner top resets and no longer applies external force to the inner ring of the bearing. The bearing falls due to gravity, and the moving block 32 continues to move towards the return section 317.

[0052] Repeat the above steps to assemble bearings in batches.

[0053] The conveyor belt 2 is provided with multiple retractable elastic sheets 22 in the gap between the inner trough 212 and the outer trough 211.

[0054] There is a gap between the inner and outer rings of the bearing. The elastic sheet 22 can support the loaded balls and prevent them from falling into the storage groove 21 and getting stuck between the inner and outer rings of the bearing. When the balls are loaded, the inner ring of the bearing is reset and coaxial with the outer ring of the bearing, which drives the elastic sheet 22 to lock the part of the conveyor belt 2 located between the inner groove 212 and the outer groove 211.

[0055] Working principle: 1. After the device is started, the drive motor drives the drive shaft 35 to rotate through the belt drive. The pulley 36 drives the belt to move. The belt drives the moving block 32 to move along the ring frame 31 through the elastic telescopic rod 37. The spacing of the moving block 32 matches the spacing of the storage groove 21 to ensure that the telescopic column 33 corresponds to the storage groove 21. When the telescopic column 33 moves to the feeding section 311, the external force causes the telescopic end of the telescopic column 33 to move upward. The inner and outer rings of the bearing are put into the inner groove 212 and the outer groove 211 respectively. Then the telescopic end is inserted into the inner ring of the bearing, limiting the inner ring of the bearing in the through section, so that a gap for ball filling is formed between the inner and outer rings of the bearing.

[0056] 2. The telescopic column 33 moves with the moving block 32 to the correction and limiting section 312, causing the piston rod 333 to abut against the guide slope of the guide plate 13. The piston rod 333 moves down to compress the gas in the through groove 332, pushing the inner top block 331 to move outward and press against the inner ring of the bearing, thereby achieving relative fixation between the inner ring of the bearing and the telescopic column 33. The inner ring of the bearing is continuously limited to ensure the stability of the gap between the inner and outer rings of the bearing, providing conditions for subsequent ball filling. The conveyor belt 2 moves synchronously with the bearing.

[0057] 3. When the bearing is moved to the second feeding section 313, balls coated with lubricating oil are filled into the gap between the inner and outer rings. The elastic sheet 22 on the conveyor belt 2 supports the balls and prevents them from falling into the storage trough 21. After filling, the moving block 32 drives the telescopic column 33 into the bending section 314, moving the inner ring of the bearing from the through section to the inner groove 212, so that the inner and outer rings of the bearing are restored to the coaxial state. The balls are stuck between the inner and outer rings of the bearing, and the elastic sheet 22 is locked inside the part of the conveyor belt 2 located inside the storage trough 21 as the inner ring of the bearing is reset.

[0058] 4. The telescopic column 33 drives the bearing into the uniform distribution section 315. The gear 15 on the telescopic column 33 meshes with the rack plate 14. When the moving block 32 moves, it drives the gear 15 to rotate, thereby making the telescopic column 33 and the inner ring of the bearing rotate synchronously, so as to achieve uniform distribution of the balls between the inner and outer rings of the bearing, and complete the bearing assembly. The assembled bearing is carried to the unloading section 316. The piston rod 333 resets, causing the inner top block 331 to release the inner ring. The bearing falls off by gravity, and the moving block 32 moves to the return section 317. The above process is repeated to realize the batch assembly of bearings.
