It can simulate extreme conditions in actual operation, thus ensuring the reliability and stability of bearings in actual use.
[0003] When testing the rapid speed change of existing high-speed bearings, the air gun blowing method is usually used to quickly accelerate the bearings. However, the position of the air gun is fixed. When testing bearings of different sizes, the blowing position of the air gun cannot be adjusted to a suitable position, which affects the acceleration of the bearings, making it difficult for the bearings to reach a high-speed state and resulting in inaccurate test results. Therefore, we propose a rapid speed change testing device for high-speed bearings. Summary of the Utility Model

[0026] Please refer to Figures 1-5 As shown, the present utility model is a high-speed bearing rapid speed change test device, including a workbench 1. A detection device 11 is fixedly connected to the top of the workbench 1. A test seat 111 is fixedly connected to the right side of the detection device 11. A temperature sensor and a vibration sensor are fixedly connected to the right side of the test seat 111. A fixed shaft 112 is fixedly connected to the center of the right side of the test seat 111. An adjustment assembly 12 is arranged to the right of the test seat 111. A fixed seat 13 is fixedly connected to the top right side of the workbench 1.
[0027] The adjustment assembly 12 includes a moving seat 121. A lifting seat 122 is in contact with the front of the moving seat 121. A fixed block 221 is fixedly connected to the top of the lifting seat 122. An air delivery pipe 222 is fixedly connected to the left side of the fixed block 221. A connecting frame 223 is fixedly connected to the left side of the air delivery pipe 222. A blowing pipe 224 is fixedly connected to the left side of the connecting frame 223. An air pipe joint 225 is fixedly connected to the right side of the fixed block 221. By setting the adjustment assembly 12, specifically, pulling the moving seat 121 to adjust the front and back position of the blowing pipe 224, and then rotating the second turning handle 214 to drive the second threaded rod 212 to rotate, the internal threaded block 213 drives the lifting seat 122 to move up or down, adjusting the height of the blowing pipe 224, so that the blowing pipe 224 can smoothly move to a suitable position, ensuring stability during blowing and enabling the bearing to quickly reach the required high-speed state.
[0028] A bolt 211 is threadedly connected inside the moving seat 121. A fixing plate 123 is fixedly connected to the back of the moving seat 121. Two sliding rods 231 are fixedly connected to the back of the fixing plate 123. Two sliding grooves are formed at the bottom of the moving seat 121. The inner walls of the two sliding grooves are both slidably connected with a track 124. The bottoms of the two tracks 124 are both fixedly connected to the top of the workbench 1. Pulling the moving seat 121 to adjust the front and back position of the blowing pipe 224, the bottom of the moving seat 121 slides on the track 124, and the sliding rods 231 slide on the fixed seat 13, which can make the moving seat 121 move more stably.
[0029] A sliding groove is formed inside the moving seat 121. A second threaded rod 212 is arranged inside the sliding groove. The top and bottom of the second threaded rod 212 are both rotatably connected to the moving seat 121. The top of the second threaded rod 212 penetrates through the moving seat 121 and extends to the outside. A second turning handle 214 is fixedly connected to the top of the second threaded rod 212. An internal threaded block 213 is threadedly connected to the outer surface of the second threaded rod 212.
[0030] The front surface of the internal thread block 213 penetrates through the moving seat 121 and extends to the outside. The front surface of the internal thread block 213 is fixedly connected to the back surface of the lifting seat 122. The outer surface of the internal thread block 213 is slidably connected to the inner wall of the chute opened inside the moving seat 121. The back surfaces of both slide bars 231 penetrate through the fixed seat 13 and extend to the outside. The slide bars 231 are slidably connected to the fixed seat 13. Since the internal thread block 213 is slidably connected to the moving seat 121, the internal thread block 213 will move linearly upward or downward.
[0031] A positioning ring 21 is fixedly connected to the outer surface of the fixed shaft 112. A threaded block 22 is fixedly connected to the right side of the fixed shaft 112. An extrusion ring 23 is threadedly connected to the outer surface of the threaded block 22. A threaded hole is opened at the top of the protruding position on the right side of the test seat 111, and a receiving groove is opened at the bottom of the protruding position on the right side of the test seat 111. A square groove is opened on the front surface of the receiving groove. The bearing is sleeved on the fixed shaft 112 and contacts the positioning ring 21. Then, the extrusion ring 23 is threadedly connected to the threaded block 22. When the left side of the extrusion ring 23 contacts the inner ring of the bearing, the bearing is clamped and fixed. Since the extrusion ring 23 has a moving distance in the left-right direction, bearings with different widths can be clamped and fixed.
[0032] A first threaded rod 113 is threadedly connected to the inner wall of the threaded hole. A first turning handle 31 is fixedly connected to the top of the first threaded rod 113. The bottom of the first threaded rod 113 is rotatably connected to a limiting ring 32. A lifting block 114 is fixedly connected to the bottom of the limiting ring 32. A decelerating block 41 is fixedly connected to the bottom of the lifting block 114. A limiting convex block 42 is fixedly connected to the front surface of the lifting block 114. The outer surface of the lifting block 114 is slidably connected to the inner wall of the receiving groove. The limiting convex block 42 is slidably connected to the inner wall of the square groove. By providing the lifting block 114, specifically, turning the first turning handle 31 drives the first threaded rod 113 to rotate, then the first threaded rod 113 drives the lifting block 114 to move upward or downward through the limiting ring 32. The limiting convex block 42 is used to play a limiting role to make the lifting block 114 move linearly. Since the lifting block 114 has an up-and-down moving space, bearings of different sizes can be tested, making the device more applicable.
[0033] A specific application of this embodiment is:
[0034] The bearing is sleeved on the fixed shaft 112 and contacted with the positioning ring 21, and then the extrusion ring 23 is threadedly connected with the threaded block 22. When the left side of the extrusion ring 23 contacts the inner ring of the bearing, the bearing is clamped and fixed. Since the extrusion ring 23 has a movable distance in the left and right directions, it can clamp and fix bearings of different widths. Then pull the movable seat 121 to adjust the front and rear position of the blowing pipe 224, and the bottom of the movable seat 121 slides on the track 124, and the sliding rod 231 slides on the fixed seat 13, which can make the movable seat 121 more stable when moving. After the adjustment of the movable seat 121 is completed, turn the bolt 211 clockwise to make it contact with the workbench 1, thereby fixing the movable seat 121, and the position of the blowing pipe 224 is fixed, and then turn the handle 214 to drive the threaded rod 212 to rotate, and the internal threaded block 213 drives the lifting seat 122 to move upward or downward, adjust the height of the blowing pipe 224, so that the blowing pipe 224 can be smoothly moved to the appropriate position, ensuring stability during blowing, so that the bearing can quickly reach When the speed reaches the required high speed state, after the adjustment is completed, the air pipe is connected to the air pipe joint 225, and then the gas is transported through the air pipe. The gas is blown out from the air pipe 224 through the air supply pipe 222 and the connecting frame 223. After the blown gas contacts the bearing, it will push the bearing to rotate at high speed. When the high speed is reached, the clockwise rotation of the handle 131 drives the threaded rod 113 to rotate clockwise, and the threaded rod 113 drives the lifting block 114 to move downward through the limit ring 32. The limit protrusion 42 is used to play a limiting role, so that the lifting block 114 moves linearly. When the bottom of the deceleration block 41 contacts the bearing, the bearing will be quickly decelerated to achieve the effect of rapid speed change. Then the detection equipment 11 will detect the rapid speed change of the bearing. Since the lifting block 114 has space to move up and down, it can test bearings of different sizes, making the equipment more applicable. The test seat 111 is provided with a temperature sensor and a vibration sensor, which can accurately measure the temperature change and vibration of the bearing during the test.
