Description

Technical Field

[0001] This utility model relates to the technical field of bearing testing devices, and more specifically to a bearing testing device. Background Technology

[0002] Self-lubricating bearings achieve continuous lubrication through the inherent properties of the material itself. They are typically cylindrical with evenly distributed holes on the outer wall to store lubricant. During friction, the lubricant gradually transfers to the surface of the shaft, forming a lubricating film that separates the metal parts, thereby reducing frictional losses.

[0003] To prevent self-lubricating bearings from wearing out or even cracking under high load or high speed operating conditions, it is necessary to test them to determine their rated load. However, bearing load tests often require testing multiple sets of bearings from the same batch to improve the accuracy of the experimental data. Since existing testing devices can often only test a single set of bearings, and the testing process takes a lot of time to cause the bearing to break down and record the data, the test time is greatly extended, which in turn affects the testing efficiency of self-lubricating bearings. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies and to solve the problem of how to quickly perform load testing on self-lubricating bearings.

[0028] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0029] like Figure 1-5 As shown, a bearing testing device includes a bearing body 7, and further includes:

[0030] The base 1 is equipped with an axial detection component 4, and the base 1 has detection stations arranged in a linear array.

[0031] Transmission unit 3 is mounted on base 1 and includes a rotating cylinder 35.

[0032] The detection unit 2 is set on the detection station. The detection unit 2 includes a detection block 21 and a clamping member 23 set on the detection block 21. The clamping member 23 is fixed on the rotating cylinder 35. The bearing body 7 is fixed on the detection block 21 and cooperates with the rotating cylinder 35. A radial detection member 6 is set on the detection block 21.

[0033] The output ends of both the axial detection element 4 and the radial detection element 6 face the bearing body 7.

[0034] Specifically, the base 1 supports the parts in the detection unit 2 and the transmission unit 3. When multiple bearing bodies 7 are being tested, the bearing bodies 7 are clamped onto the detection block 21 one by one, and the bearing bodies 7 are fixed by the clamping member 23. At this time, the transmission unit 3 drives the rotating cylinder 35 to rotate, so that the clamping member 23 engages with the inner ring of the bearing body 7 to rotate. At the same time, axial load or radial load can be applied to the bearing body 7 through the axial detection member 4 and the radial detection member 6 to detect the service life of the bearing body 7 under different loads. If the bearing body 7 makes abnormal noise or is damaged during the test, the output of the transmission unit 3 can be stopped, the clamping member 23 clamped on the bearing body 7 that makes abnormal noise can be removed, and the time of damage can be recorded. Then the transmission unit 3 is run again to test the remaining bearing bodies 7 until all bearing bodies 7 are damaged, and the recorded values ​​of the bearing bodies 7 are compared to improve the accuracy of the test values ​​and the testing efficiency of the bearing bodies 7.

[0035] As a further embodiment of this utility model, the detection block 21 is provided with an outer ring retaining block 24, which engages with the outer ring of the bearing body 7. The clamping member 23 includes a first connecting rod 236, a second connecting rod 237, and a support sleeve 233 that is engaged with the rotating cylinder 35. A top ring 235 is threaded onto the support sleeve 233, and a rotating ring 232 is rotatably disposed on the top ring 235. The first connecting rod 236 is rotatably disposed on the rotating ring 232 and is connected to the second connecting rod 237. The bearing body 7 is connected in phase 7. The second connecting rod 237 is provided with an inner ring clamping block 231 that engages with the inner ring of the bearing body 7. When the top ring 235 slides on the threaded groove 234 on the support sleeve 233, it pushes the rotating ring 232 to slide upward or downward in the vertical direction. As the rotating ring 232 slides, the first connecting rod 236 pushes the second connecting rod 237 to swing on the support sleeve 233, thereby adjusting the clamping range of the inner ring clamping block 231 to adapt to bearing bodies 7 of different specifications.

[0036] As a further embodiment of this utility model, a groove 238 is provided on the second connecting rod 237, and one end of the first connecting rod 236 slides in the groove 238. The first connecting rod 236 slides downward so that it pushes the second connecting rod 237 to swing on the support sleeve 233 through the groove 238, thereby adjusting the clamping range of the inner ring clamping block 231 to adapt to bearing bodies 7 of different specifications.

[0037] As a further embodiment of this utility model, the detection block 21 is provided with bolts 22 for fixing the outer ring retainer 24. The outer ring retainer 24 is detachable. When the bearing body 7 with a different outer diameter is replaced, the outer ring retainer 24 can be removed to assemble a new outer ring retainer 24. The inner diameter of the new outer ring retainer 24 is adapted to the outer ring of the bearing body 7. The outer ring retainer 24 is provided with a notch, and the second pressure block 63 is located at this notch to apply a radial load to the bearing body 7.

[0038] As a further embodiment of this utility model, the base 1 includes a top plate 12 and a raised plate 11. A raised block 13 is provided between the raised plate 11 and the top plate 12. An axial detection component 4 is fixed on the raised plate 11. The top plate 12, the raised plate 11 and the raised block 13 are combined to raise the first cylinder 41. The raised distance is the sliding distance that the push rod 42 can slide.

[0039] As a further embodiment of this utility model, the axial detection component 4 includes a first cylinder 41 and a push rod 42 disposed at the output end of the first cylinder 41. The push rod 42 is provided with a first pressure block 43 arranged in a linear array. The first pressure block 43 applies pressure to the bearing body 7 along the axial direction of the push rod 42 to detect the axial load. The first cylinder 41 is a power drive component to drive the push rod 42 to slide within the rotating cylinder 35 so that the first pressure block 43 contacts the bearing body 7. The first pressure block 43 slides within the groove 34.

[0040] As a further embodiment of this utility model, the radial detection component 6 includes a second cylinder 61, a spring 62, and a second pressure block 63. The spring 62 is disposed between the second cylinder 61 and the second pressure block 63. The second pressure block 63 is slidably disposed on the detection block 21. The second cylinder 61 outputs to drive the second pressure block 63 to slide through the spring 62. The second pressure block 63 slides on the detection block 21 until it contacts the bearing body 7 to align and apply pressure, so as to adjust the force of the second cylinder 61 according to the required radial load value, so as to enable detection under different radial loads.

[0041] As a further embodiment of this utility model, pressure sensors 5 are provided on both the radial detection element 6 and the axial detection element 4. The pressure sensor 5 is model MPX4250D. The pressure sensor 5 is used to detect the output pressure of the radial detection element 6 and the axial detection element 4 to ensure that the bearing body 7 is subjected to load tests under rated pressure or different pressures.

[0042] As a further embodiment of this utility model, a groove 34 is provided on the rotating cylinder 35, and the clamping member 23 is fixed on the rotating cylinder 35 through the groove 34. The groove 34 plays a guiding and supporting role. When the rotating cylinder 35 rotates, the clamping member 23 is driven to rotate synchronously through the groove 34. At the same time, the clamping member 23 can slide and adjust its position within the groove 34. The clamping member 23 is fixed to the groove 34 by bolts 22.

[0043] As a further embodiment of this utility model, the transmission unit 3 includes a driven wheel 36, a motor 31, and a driving wheel 32 disposed at the output end of the motor 31. A synchronous belt 33 is disposed between the driving wheel 32 and the driven wheel 36. The driven wheel 36 is engaged with the rotating cylinder 35. The motor 31 is model number MHMF042L1U4-1116. The motor 31 serves as the power source. When the bearing body 7 is fixed to the detection block 21, the motor 31 runs to drive the driving wheel 32 to rotate. The driving wheel 32 drives the driven wheel 36 and the rotating cylinder 35 to rotate through the synchronous belt 33, causing the clamping member 23 to engage with the inner ring of the bearing body 7 to rotate. Through static load and dynamic load tests, the bearing's resistance to deformation under rated load is confirmed, and the fatigue life of the bearing body 7 is tested. When the speed of the motor 31 is increased, the efficiency of the cyclic test is accelerated.

[0044] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.
