[0020] Please refer to the attached Figure 1 - attached Figure 11, a device for detecting the dynamic friction performance of multiple parameters of a bearing according to the present invention, includes a device main body 1 and a receiving seat 2. The device main body 1 includes a buffer structure 4, a bearing member 7 connected to the buffer structure 4, a vertical adaptation structure 12 connected to the bearing member 7, a horizontal adaptation structure 11 connected to the vertical adaptation structure 12, and a sliding structure 116 connected to the horizontal adaptation structure 11. The horizontal adaptation structure 11 includes a support rod 111, a cross bar 112, a hydraulic rod 113, a first slider 114, and a sliding frame 115. Two cross bars 112 are arranged in front of the support rod 111. Chutes are provided inside both of the two cross bars 112. Two hydraulic rods 113 are respectively arranged inside the cross bars 112.

Through the cooperation of the horizontal adaptation structure 11, the vertical adaptation structure 12, and the sliding structure 116, it is convenient to meet the detection requirements for bearings with four different orientations and different diameter structures, and realize rapid adjustment and stable clamping in the horizontal, vertical, and different height directions.
[0021] Embodiment 1: The buffer structure 4 includes a first buffer pad 41, a second buffer pad 42, a support inclined plate 43, a buffer block 44, a sliding rod 45, a spring 46, and a limiting frame 47. The second buffer pad 42 is arranged at the bottom of the first buffer pad 41. Two support inclined plates 43 are respectively arranged on both sides of the first buffer pad 41. The buffer block 44 and the spring 46 are both arranged on the sliding rod 45. The number of the support inclined plates 43, the buffer block 44, the spring 46, and the sliding rod 45 is set to two, and the two support inclined plates 43, the buffer block 44, the spring 46, and the sliding rod 45 are all symmetrically arranged; Specifically, by setting the buffer blocks 44 at the bottoms of the two-sided support inclined plates 43 in the buffer structure 4 to slide on the slide rods 45 and the springs 46, the buffering of the motor 74 is realized, effectively alleviating the stress generated by the motor 74 during operation due to vibration, start-stop or external impact. The elastic force of the spring 46 can absorb and consume the vibration energy, preventing the vibration from being directly transmitted to the key components of the motor 74, thereby reducing the risk of wear and damage of the components and extending the service life of the motor 74. The sliding fit design between the buffer block 44 and the slide rod 45 ensures the smoothness and orientation of the buffering process, making the buffering effect more uniform and reliable. It can not only protect the normal operation of the motor 74, but also reduce the noise during equipment operation and improve the comfort of the overall working environment. The elastic coefficient of the spring 46 can be adjusted according to actual needs to meet the requirements of the buffering degree of the motor 74 under different working conditions, enhancing the versatility and adaptability of the buffer structure 4.
[0022] Embodiment 2: The bearing member 7 includes an outer ring 72 and a motor 74. Rotating shafts 73 are arranged on all four sides of the motor 74.

The numbers of the inner rings 71, the outer rings 72, and the rotating shafts 73 are all four. A temperature sensor 8 is sleeved on the outer ring 72. A laser displacement sensor 9 is arranged on the rotating shaft 73. An acceleration sensor 10 is arranged at the bottom of the laser displacement sensor 9. The numbers of the temperature sensor 8, the laser displacement sensor 9, and the acceleration sensor 10 are all four. A protective box 6 is arranged outside the motor 74.

Through holes are opened on all four sides of the protective box 6, and the rotating shaft 73 passes through the interior of the through holes; Specifically, by sleeving the temperature sensor 8 on the outer bearing ring 72, the temperature change of the bearing during operation can be accurately obtained in real time. Since friction will occur between the rolling elements inside the bearing and the inner ring 71 and the outer ring 72 during equipment operation, and this friction will cause the bearing temperature to rise. Once the temperature exceeds the normal range, it may indicate problems such as poor lubrication, excessive load, or improper installation of the bearing. By arranging a laser displacement sensor 9 on the rotating shaft 73, the operating state of the rotating shaft 73 is accurately monitored. Minor changes in the displacement and vibration of the rotating shaft 73 may affect the normal operation and working accuracy of the entire equipment. By arranging an acceleration sensor 10 at the bottom of the laser displacement sensor 9, the vibration, impact, rotational speed, and torque fluctuations of the rotating shaft 73 and the bearing are detected, facilitating the use of the acceleration sensor 10 in different scenarios.

By arranging anti-slip pads at the bottoms of the fixed blocks, the stability and reliability between the fixed blocks and the supporting surface can be significantly improved.
[0024] Example 5: Both the horizontal adaptation structure 11 and the vertical adaptation structure 12 are arranged on the receiving seat 2. The number of the second sliders 1164, the telescopic rods 1165, and the arc-shaped blocks 1166 are all set to eight, and the second sliders 1164, the telescopic rods 1165, and the arc-shaped blocks 1166 are clamped on four rotating shafts 73 in pairs. The number of the racks 1161, the gears 1162, and the rod bodies 1163 is set to four, and the two racks 1161, the gears 1162, and the rod bodies 1163 are symmetrically arranged with each other. A receiving groove 3 is formed inside the receiving seat 2. The number of the receiving grooves 3 is two, and the two receiving grooves 3 are symmetrically arranged with each other. The structures of the horizontal adaptation structure 11 and the vertical adaptation structure 12 are the same, and the vertical adaptation structure 12 is arranged at the bottom of the horizontal adaptation structure 11. Two groups of horizontal adaptation structures 11 are arranged inside the fixed frame; Specifically, by setting the adjusting rod 1160 in the horizontal adaptation structure 11 to extend, the rack 1161 is driven to move on the fixed frame, thereby driving the engaged gear 1162 to move on the side section 11632, driving the bidirectional threaded section 11631 to rotate clockwise, and the two second sliders 1164, the telescopic rods 1165, and the arc-shaped blocks 1166 all move closer to each other, realizing the clamping of the bearings in two horizontal directions.
[0025] Specifically, through the cooperation of the horizontally arranged horizontal adaptation structure 11 and the vertically arranged vertical adaptation structure 12 for the clamping movement of the bearings in two vertical directions, the clamping of the bearings in four different directions is realized. The temperature sensor 8, the laser displacement sensor 9, and the acceleration sensor 10 are cooperatively arranged to detect the bearings, which is convenient for comprehensively reflecting the complex load conditions borne by the bearings in the actual working environment, accurately simulating the multi-directional load conditions borne by the bearings under actual complex working conditions, and enabling the detection data to truly reflect the performance of the bearings under multi-directional forces; Embodiment Six: An elastic structure 13 is provided on the rotating shaft 73. The elastic structure 13 includes elastic steel A131, elastic steel B132, a track groove 135, and a rotating member 136. Corrugated grooves 133 are provided inside both the elastic steel A131 and the elastic steel B132. A guide rail 134 is provided on the elastic steel A131. The track groove 135 is provided inside the guide rail 134. The rotating member 136 is provided on the guide rail 134 and the elastic steel B132.

Specifically, the elastic steel B132 in the elastic structure 13 slides inside the guide rail 134, and the position of the elastic steel B132 on the guide rail 134 is locked by the bolt to cooperate with the provided horizontal adaptation structure 11 and vertical adaptation structure 12 to increase the friction of the bearing, so as to adapt to bearings of different widths.
[0026] Working principle: First, place the device main body 1 on the support surface through the provided fixing blocks and anti-slip pads. The elastic steel B132 slides inside the guide rail 134, so as to sleeve the four rotating shafts 73 in different directions. Finally, use the bolt to fix the position of the elastic steel B132. When it is necessary to clamp the four bearings in the horizontal and vertical directions to detect different working environments, start the adjusting rod 1160 to extend, drive the rack 1161 to drive on the fixed frame, thereby driving the engaged gear 1162 to drive on the side section 11632, and thus drive the bidirectional threaded section 11631 to rotate clockwise. The two sliders two 1164, the telescopic rod 1165, and the arc-shaped block 1166 all approach each other, and the clamping movement of the four bearings in the vertical and horizontal directions can be realized. When it is necessary to release the clamping of the two horizontal and vertical directions, start the adjusting rod 1160 to shorten, drive the rack 1161 to drive on the fixed frame, thereby driving the engaged gear 1162 to drive on the side section 11632, and thus drive the bidirectional threaded section 11631 to rotate counterclockwise. The two sliders two 1164, the telescopic rod 1165, and the arc-shaped block 1166 all move away from each other to release the two bearings in the horizontal direction. The provided telescopic rod 1165 realizes the height displacement. Turn on the controller, start the motor 74 to drive the four rotating shafts 73 in different directions to rotate. At this time, start the temperature sensor 8 to detect the temperature change of the bearing during operation in real time, the laser displacement sensor 9 to accurately monitor the operating state of the rotating shaft 73, and the acceleration sensor 10 to detect the vibration, impact, rotational speed, and torque fluctuation of the rotating shaft 73 and the bearing, which is convenient for the device main body 1 to be used in different scenarios and convenient for the staff to compare and evaluate the four bearings in different directions. Thus, the entire work process ends.
