Description

Technical Field

[0001] This invention belongs to the field of bearing outer ring creep detection technology, specifically a bearing outer ring creep detection device. Background Technology

[0002] When the outer ring of a bearing rotates relative to its housing, it usually indicates a problem with the bearing's fit. This phenomenon is called "outer ring running" or "outer ring creep." It can lead to wear on the bearing housing, increased vibration, increased noise, and even premature bearing failure. Therefore, after a bearing is manufactured, an outer ring creep test is required.

[0003] Patent CN219551863U discloses a high-precision motor bearing outer ring creep detection device, including a base, a first locking mechanism, and a second locking mechanism. The first locking mechanism includes components such as a lower support ring, an upper support ring, and a temperature detector. The second locking mechanism includes components such as a support column and a clamping column. This solution drives the clamping column to rotate and fit against the bearing inner ring. Then, the sliding base is slid to align the lower support ring with the bearing. The third screw is rotated to fit against the base for locking. Then, the lead screw is rotated to drive the lower support ring to slide along the guide plate to approach the bearing outer ring. Then, the second screw is rotated to bring the upper support ring closer to the lower support ring to clamp the bearing outer ring, thus fixing the inner and outer rings of the bearing. The motor is started to drive the support column to rotate to simulate the daily use of the bearing. At this time, the temperature detector detects the temperature fluctuation of the lower support ring to determine whether there is a creep phenomenon in the bearing outer ring.

[0004] In the above-mentioned scheme, before the bearing is tested, the first locking mechanism and the second locking mechanism need to be operated separately to fix the inner and outer rings of the bearing. This operation is cumbersome and troublesome, which affects the efficiency of the outer ring creep detection. Secondly, there are a small number of substandard bearings in the bearing sample. The clearance error between the inner ball and the inner and outer rings of these bearings is large. When the bearing is tested, the inner ring of the bearing is rotating at high speed, and the ball will repeatedly impact inside the bearing, causing the inner cage of the bearing to break. The broken cage will fly out with the centrifugal force of rotation, causing accidental injury to personnel. Therefore, the present invention provides a bearing outer ring creep detection device. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows: A bearing outer ring creep detection device of this invention includes a base plate, a detection box on the base plate, a feeding groove for placing bearings on the detection box, guide strips symmetrically arranged on both sides of the feeding groove, the guide strips slidably connected to a protective plate, an inner ring fixing mechanism for fixing the inner ring of the bearing is provided inside the detection box, two sets of outer ring fixing fixtures for clamping the bearing are symmetrically and movably installed inside the detection box, a movable rod is inserted into the inner ring fixing mechanism, a cylinder for driving the movable rod is fixedly installed on the base plate, the movable rod drives the two sets of outer ring fixing fixtures to merge through two sets of linkage mechanisms, a creep detection mechanism is provided inside the outer ring fixing fixture, the inner ring fixing mechanism includes a fixing column, the fixing column is rotatably installed inside the detection box, and the movable rod is inserted into the fixing column. A bracket mechanism for supporting the bearing is installed on a fixed column. A movable shaft is set inside the fixed column and fixedly installed on a movable rod. One end of the connecting rod is hinged to the movable shaft, and the other end of the connecting rod is hinged to a positioning block. Three sets of clearance holes are opened at equal angles on the upper end of the fixed column. The positioning block is movably inserted into the clearance holes. The linkage mechanism includes two sets of fixed frames. The movable rod is fixedly connected in the middle of the fixed frame. Two sets of linkage plates are connected to both ends of the fixed frame. The linkage plates are movably inserted into the test box. An inclined groove is opened at the upper end of the linkage plate. A pin is set in the inclined groove. Two sets of support plates are connected to both ends of the pin. An outer ring fixing device is fixedly connected to the upper end of the support plate. A gear sleeve is fixedly installed at the lower end of the fixed column. The gear sleeve meshes with a gear. The gear is rotatably installed at the bottom of the test box. A motor for driving the gear is also fixedly installed on the bottom plate.

[0007] The bearing is sealed in the discharge trough by a protective plate to prevent the bearing cage from breaking and injuring workers. Secondly, by driving the movable rod to move upward, the inner and outer rings of the bearing can be fixed at the same time, which makes it easier for workers to fix the inner and outer rings of the bearing and improves the efficiency of bearing inspection.

[0008] Preferably, sliding sleeves are installed on both sides of the outer ring fixture, the sliding sleeves are slidably connected to the sliding rod, and the sliding rod is fixedly installed inside the testing box;

[0009] The outer ring fixing device drives the sliding sleeve to slide along the sliding rod, which guides the movement of the outer ring fixing device.

[0010] Preferably, the bracket mechanism includes a movable plate, which is movably fitted onto a fixed column. The fixed plate is fixedly installed on the fixed column. A first spring is disposed between the fixed plate and the movable plate and is fitted onto the fixed column. Three sets of guide blocks are fixedly installed on the inner ring of the movable plate. Hooks are fixedly connected to the guide blocks. Two sets of fixed hooks engage with the hooks. A movable hook is movably installed below the two sets of fixed hooks. Three sets of guide grooves are equally spaced on the fixed column. The guide blocks are slidably connected to the guide grooves. The fixed hooks are fixedly installed in the guide grooves. A rectangular slide groove is provided on the movable hook. The rectangular slide groove is slidably connected to a guide rail. Limit plates are provided at both ends of the guide rail. The guide rail is fixedly installed in the guide grooves. A first inclined surface is provided on the fixed hook. A second inclined surface is provided on the movable hook.

[0011] The movable block is blocked by the guide rail end limit plate and cannot move. The lower end of the hook will be offset from the movable block, so that the bearing is pushed to the outside of the discharge chute, making it easier for the staff to remove the bearing.

[0012] Preferably, the peristalsis detection mechanism includes a roller, which is rotatably mounted inside an outer ring fixture. A driven wheel is rotatably connected to the roller and is also rotatably mounted inside the outer ring fixture. One end of a drive rod is hinged to the driven wheel, and the other end of the drive rod is hinged to a slider. A pressure sensor is fixedly mounted inside the outer ring fixture. A second spring is provided between the slider and the pressure sensor. Guide sleeves are installed on both sides of the slider. Both sides of the outer ring fixture have clearance grooves. Guide rods are fixedly installed in the clearance grooves, and the guide sleeves are slidably connected to the guide rods.

[0013] The moving slider further compresses the second spring, increasing the squeezing force exerted by the second spring on the pressure sensor. This causes the pressure sensor's display to show a larger pressure value, thus detecting creep in the bearing's outer ring. Conversely, if the pressure sensor's display shows a constant pressure value, the bearing's outer ring does not creep.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. The bearing is sealed in the discharge trough by a protective plate to prevent the bearing cage from breaking and injuring the staff. Secondly, by driving the movable rod to move upward, the inner and outer rings of the bearing can be fixed at the same time, which makes it easier for the staff to fix the inner and outer rings of the bearing and improves the efficiency of bearing inspection.

[0016] 2. Pressing the bearing causes it to press the movable plate downwards, further compressing the first spring. Simultaneously, the movable plate drives three sets of guide blocks to slide along the three sets of guide grooves. The guide blocks cause the lower end of the hook to press against the second inclined surface of the movable block. Guided by the second inclined surface, the hook bends to one side until the lower end of the hook touches the protrusion of the movable block and cannot move. Under the rebound force of the hook, the lower end of the hook will press tightly against the movable block, releasing the pressure on the bearing. Under the rebound force of the first spring, the movable plate pushes the bearing upwards. At the same time, the movable plate drives the guide block, along with the hook and the movable block, to move upwards. The movable block slides along the guide rail until it moves between the two sets of fixed blocks, and the first inclined surface and the second inclined surface on the movable block are on the same plane. At this point, the movable block is blocked by the guide rail end limit plate and cannot move. The lower end of the hook will be offset from the movable block, pushing the bearing to the outside of the discharge chute, making it easy for workers to remove the bearing.

[0017] 3. When the peristalsis detection mechanism detects the bearing, the roller is in close contact with the outer ring of the bearing, while the inner ring rotates at high speed. If the outer ring of the bearing peristalsis occurs, the peristaltic outer ring drives the roller to rotate, and the rotating roller drives the driven wheel to rotate. The driven wheel drives the slider to move towards the pressure sensor via the drive rod, and the slider drives the guide sleeve to slide along the guide rod, which guides the movement of the slider. The moving slider further compresses the second spring, increasing the pressure exerted by the second spring on the pressure sensor. This causes the pressure sensor's display to show a larger pressure value, thus detecting peristalsis in the outer ring of the bearing. Conversely, if the pressure sensor's display shows a constant pressure value, the outer ring of the bearing has not peristalsis. Attached Figure Description

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0037] Example 1: As Figures 1 to 3As shown in the embodiment of the present invention, a bearing outer ring creep detection device includes a base plate 1, a detection box 2 on the base plate 1, a feeding groove 3 for placing bearings 4 on the detection box 2, guide strips 5 symmetrically arranged on both sides of the feeding groove 3, the guide strips 5 slidably connected to a protective plate 6, an inner ring fixing mechanism 7 for fixing the inner ring of the bearing 4 is provided inside the detection box 2, two sets of outer ring fixing fixtures 11 for clamping the bearing 4 are symmetrically and movably installed inside the detection box 2, the inner ring fixing mechanism 7 is inserted into a movable rod 8, a cylinder 9 for driving the movable rod 8 is fixedly installed on the base plate 1, the movable rod 8 drives the two sets of outer ring fixing fixtures 11 to merge through two sets of linkage mechanisms 10, a creep detection mechanism 12 is provided inside the outer ring fixing fixture 11, the inner ring fixing mechanism 7 includes a fixing column 701, the fixing column 701 is rotatably installed inside the detection box 2, the movable rod 8 is inserted into the fixing column 701, a bracket mechanism 702 for supporting the bearing 4 is installed on the fixing column 701, and a movable rod 8 is provided inside the fixing column 701. Shaft 703 is fixedly mounted on movable rod 8. One end of connecting rod 704 is hinged to movable shaft 703, and the other end of connecting rod 704 is hinged to positioning block 705. Three sets of clearance holes 7011 are opened at equal angles on the upper end of fixed column 701. Positioning block 705 is movably inserted into clearance holes 7011. Linkage mechanism 10 includes two sets of fixed frames 101. Movable rod 8 is fixedly connected to the middle of fixed frame 101. Two sets of linkage plates 102 are respectively connected to both ends of fixed frame 101. The movable plate 102 is inserted into the test box 2. The upper end of the connecting plate 102 is provided with an inclined groove 103. The inclined groove 103 is provided with a pin 104. The two ends of the pin 104 are respectively connected to two sets of support plates 105. The upper end of the support plate 105 is fixedly connected to the outer ring fixing fixture 11. The lower end of the fixing column 701 is fixedly fitted with a gear sleeve 706. The gear sleeve 706 meshes with a gear 707. The gear 707 is rotatably installed at the bottom of the test box 2. The base plate 1 is also fixedly installed with a motor 708 for driving the gear 707.

[0038] Specifically, the inner diameter of the discharge trough 3 is larger than the outer diameter of the bearing 4. When the bearing 4 needs to be inspected, the bearing 4 is placed in the discharge trough 3, and the inner ring of the bearing 4 is fitted onto the end of the fixed column 701. The bracket mechanism 702 supports the inner ring of the bearing 4. Then, the cylinder 9 is activated, which pushes the movable rod 8 and the movable shaft 703 upward. The movable shaft 703 pushes the three sets of connecting rods 704, causing the three sets of connecting rods 704 to push the three sets of positioning blocks 705 along the clearance. The hole 7011 moves toward the inner ring wall of the bearing 4. At the same time, the two sets of fixing brackets 101 move upward with the movable rod 8. The fixing brackets 101 drive the two sets of connecting plates 102 to move upward. As the two sets of connecting plates 102 move, the two sets of pins 104 slide along the two sets of inclined grooves 103 respectively. Under the guidance of the inclined grooves 103, the two sets of pins 104 drive the corresponding support plates 105. Through the support plates 105, the two sets of outer ring fixing fixtures 11 move toward each other until the positioning block 705 presses against them. The inner ring of bearing 4 is fixed, and the two sets of outer ring fixing devices 11 clamp the outer ring of bearing 4, thus fixing the outer ring of bearing 4. Then, the protective plate 6 is pulled to slide along the two sets of guide strips 5, so that the protective plate 6 covers bearing 4 in the discharge trough 3. Then, the motor 708 drives the gear 707 to rotate. The gear 707 drives the fixing column 701 to rotate through the gear sleeve 706. The fixing column 701 drives the inner ring of bearing 4 to rotate at high speed through the three sets of positioning blocks 705. During the rotation of the inner ring of bearing 4, the peristalsis detection mechanism 12 detects whether the outer ring of bearing 4 has peristalsis. Compared with the prior art, the protective plate 6 covers bearing 4 in the discharge trough 3, preventing the bearing 4 cage from breaking and injuring the staff. Secondly, by driving the movable rod 8 to move upward, the inner and outer rings of bearing 4 can be fixed at the same time, which makes it easier for the staff to fix the inner and outer rings of bearing 4 and improves the efficiency of bearing 4 inspection.

[0039] Furthermore, sliding sleeves 111 are installed on both sides of the outer ring fixture 11, and the sliding sleeves 111 are slidably connected to the sliding rods 112, which are fixedly installed inside the testing box 2.

[0040] Specifically, during the process of the two sets of outer ring fixings 11 moving towards each other, the outer ring fixings 11 drive the sliding sleeve 111 to slide along the sliding rod 112, which plays a guiding role in the movement of the outer ring fixings 11.

[0041] like Figures 4 to 7As shown, the bracket mechanism 702 includes a movable plate 7021, which is movably fitted onto a fixed post 701. A fixed plate 7022 is fixedly installed on the fixed post 701. A first spring 7023 is disposed between the fixed plate 7022 and the movable plate 7021 and is fitted onto the fixed post 701. Three sets of guide blocks 7024 are fixedly installed on the inner ring of the movable plate 7021. Hooks 7025 are fixedly connected to the guide blocks 7024. Two sets of fixing blocks 7026 engage with the hooks 7025. Below the two sets of fixing blocks 7026, a movably mounted... The movable locking block 7027 and the fixed column 701 have three sets of guide grooves 7012 at equal angles. The guide block 7024 is slidably connected to the guide grooves 7012. The fixed locking block 7026 is fixedly installed in the guide grooves 7012. The movable locking block 7027 has a rectangular sliding groove 271. The rectangular sliding groove 271 is slidably connected to the guide rail 7028. The guide rail 7028 has limit plates 281 at both ends. The guide rail 7028 is fixedly installed in the guide grooves 7012. The fixed locking block 7026 has a first inclined surface 261. The movable locking block 7027 has a second inclined surface 272.

[0042] Specifically, the hook 7025 is made of stainless steel with good elasticity and toughness. Since the bearing 4 is placed inside the discharge trough 3, it is relatively difficult for workers to remove the bearing 4 from the discharge trough 3. The movable locking block 7027 is slightly higher than the fixed locking block 7026. In the initial state, the lower end of the hook 7025 is locked between the movable locking block 7027 and the fixed locking block 7026. After the bearing 4 is inspected, the bearing 4 is pressed, causing the bearing 4 to press the movable plate 7021 downwards. The movable plate 7021 further compresses the bearing 4. A spring 7023, along with a movable plate 7021, drives three sets of guide blocks 7024 to slide along three sets of guide grooves 7012. The guide blocks 7024 cause the lower end of the hook 7025 to press against the second inclined surface 272 of the movable block 7027. Guided by the second inclined surface 272, the hook 7025 bends to one side until its lower end abuts against the protrusion of the movable block 7027 and cannot move. Under the rebound force of the hook 7025, its lower end will tightly adhere to the movable block 7027, thus releasing the spring. In addition to pressing the bearing 4, the movable plate 7021 pushes the bearing 4 upward under the rebound force of the first spring 7023. At the same time, the movable plate 7021 drives the guide block 7024, along with the hook 7025 and the movable block 7027, to move upward. The movable block 7027 slides along the guide rail 7028 until it moves between the two sets of fixed blocks 7026, and the first inclined surface 261 and the second inclined surface 272 on the movable block 7027 are aligned. On a flat surface, the movable locking block 7027 is blocked by the end limiting plate 281 of the guide rail 7028 and cannot move. The lower end of the hook 7025 will be offset from the movable locking block 7027, so that the bearing 4 is pushed to the outside of the discharge trough 3, making it easier for the staff to remove the bearing 4. If the next set of bearings 4 is to be tested, the bearing 4 is placed on the movable plate 7021 and the bearing 4 is pressed, so that the lower end of the hook 7025 is locked between the movable locking block 7027 and the fixed locking block 7026 again, and the bearing 4 is located in the discharge trough 3.

[0043] Example 2: Figure 8 and Figure 9 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the peristalsis detection mechanism 12 includes a roller 121, which is rotatably installed in the outer ring fixture 11. A driven wheel 122 is rotatably connected to the roller 121 and is also rotatably installed in the outer ring fixture 11. One end of the drive rod 123 is hinged to the driven wheel 122, and the other end of the drive rod 123 is hinged to the slider 124. A pressure sensor 126 is fixedly installed in the outer ring fixture 11. A second spring 125 is provided between the slider 124 and the pressure sensor 126. Guide sleeves 1241 are installed on both sides of the slider 124. A clearance groove 113 is provided on both sides of the outer ring fixture 11. A guide rod 1242 is fixedly installed in the clearance groove 113, and the guide sleeve 1241 is slidably connected to the guide rod 1242.

[0044] Specifically, the rebound force of the second spring 125 acts on the pressure sensor 126. The pressure value of the pressure sensor 126 is constant, therefore the pressure value displayed on the pressure sensor 126 is constant. When the peristalsis detection mechanism 12 detects the bearing 4, the roller 121 is in close contact with the outer ring of the bearing 4, and the inner ring of the bearing 4 is rotating at high speed. If the outer ring of the bearing 4 peristalsis occurs, the peristaltic outer ring of the bearing 4 drives the roller 121 to rotate. The rotating roller 121 drives the driven wheel 122 to rotate. The driven wheel 122 drives the slider 1 through the drive rod 123. 24 moves towards the pressure sensor 126, and the slider 124 drives the guide sleeve 1241 to slide along the guide rod 1242, which guides the movement of the slider 124. The moving slider 124 further compresses the second spring 125, which increases the squeezing force of the second spring 125 on the pressure sensor 126, causing the pressure value displayed on the pressure sensor 126 to increase, thereby detecting that the outer ring of the bearing 4 has peristalsis. Conversely, if the pressure value displayed on the pressure sensor 126 remains constant, the outer ring of the bearing 4 has not peristalsis.

[0045] Working principle: The bearing 4 is placed into the discharge trough 3, and the inner ring of the bearing 4 is fitted onto the end of the fixed column 701. The bracket mechanism 702 supports the inner ring of the bearing 4. Then, the cylinder 9 is activated, which pushes the movable rod 8 and the movable shaft 703 upward. The movable shaft 703 pushes the three sets of connecting rods 704, causing the three sets of connecting rods 704 to push the three sets of positioning blocks 705 along the clearance hole 7011 towards the inner ring wall of the bearing 4. At the same time, the two sets of fixed brackets 101 move upward with the movable rod 8. The fixed brackets 101 drive the two sets of connecting plates 102 to move upward. As the two sets of connecting plates 102 move, the two sets of pins 104 slide along the two sets of inclined grooves 103. Guided by the inclined grooves 103, the two sets of pins 104 drive the... The corresponding support plate 105 causes the two sets of outer ring fixings 11 to move towards each other until the positioning block 705 presses against the inner ring of the bearing 4, thus fixing the inner ring of the bearing 4. At this time, the two sets of outer ring fixings 11 clamp the outer ring of the bearing 4, thus fixing the outer ring of the bearing 4. Then, the protective plate 6 is pulled to slide along the two sets of guide strips 5, so that the protective plate 6 covers the bearing 4 in the discharge trough 3. Then, the motor 708 drives the gear 707 to rotate. The gear 707 drives the fixing column 701 to rotate through the gear sleeve 706. The fixing column 701 drives the inner ring of the bearing 4 to rotate at high speed through the three sets of positioning blocks 705. During the rotation of the inner ring of the bearing 4, the peristalsis detection mechanism 12 detects whether the outer ring of the bearing 4 has peristalsis.

[0046] After the bearing 4 is inspected, press the bearing 4 down, causing it to press the movable plate 7021 downwards. The movable plate 7021 further compresses the first spring 7023. Simultaneously, the movable plate 7021 drives the three sets of guide blocks 7024 to slide along the three sets of guide grooves 7012. The guide blocks 7024 cause the lower end of the hook 7025 to press against the second inclined surface 272 of the movable block 7027. Guided by the second inclined surface 272, the hook 7025 bends to one side until the lower end of the hook 7025 abuts against the protrusion of the movable block 7027 and cannot move. Under the rebound force of the hook 7025, the lower end of the hook 7025 will tightly adhere to the movable block 7027, releasing the pressure on the bearing 4. Under the rebound force of 7023, the movable plate 7021 pushes the bearing 4 upward. At the same time, the movable plate 7021 drives the guide block 7024, along with the hook 7025 and the movable block 7027, to move upward. The movable block 7027 slides along the guide rail 7028 until it moves between the two sets of fixed blocks 7026. The first inclined surface 261 and the second inclined surface 272 on the movable block 7027 are on the same plane. At this time, the movable block 7027 is blocked by the end limit plate 281 of the guide rail 7028 and cannot move. The lower end of the hook 7025 will be offset from the movable block 7027, so that the bearing 4 is pushed to the outside of the discharge trough 3.

[0047] When the peristalsis detection mechanism 12 detects the bearing 4, the roller 121 is in close contact with the outer ring of the bearing 4, and the inner ring of the bearing 4 is rotating at high speed. If the outer ring of the bearing 4 peristalsis occurs, the peristaltic outer ring of the bearing 4 drives the roller 121 to rotate. The rotating roller 121 drives the driven wheel 122 to rotate. The driven wheel 122 drives the slider 124 to move towards the pressure sensor 126 through the drive rod 123. The slider 124 drives the guide sleeve 1241 to slide along the guide rod 1242, which guides the movement of the slider 124. The moving slider 124 further compresses the second spring 125, which increases the squeezing force of the second spring 125 on the pressure sensor 126, causing the pressure value displayed on the display of the pressure sensor 126 to increase, thereby detecting that the outer ring of the bearing 4 has peristalsis. Conversely, if the pressure value displayed on the display of the pressure sensor 126 remains constant, the outer ring of the bearing 4 has not peristalsis.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
