Technical Field
[0001] This utility model belongs to the field of bearing fault diagnosis technology, and specifically relates to a bearing fault diagnosis test device. Background Technology
[0002] Bearings are indispensable key components in mechanical equipment, widely used in various rotating machinery such as motors, generators, automobiles, aircraft, and industrial robots. The normal operation of bearings is crucial for the stability and reliability of equipment. However, during long-term operation, bearings are prone to failure due to various factors such as wear, fatigue, poor lubrication, and overload, leading to decreased equipment efficiency and even serious safety accidents. Therefore, accurate diagnosis and timely warning of bearing failures are of paramount importance.
[0003] When diagnosing bearing faults, the fixing effect of the inner and outer rings of the bearing is relatively poor. As a result, when the drive component rotates the bearing, it is impossible to test the bearing's fault condition at different speeds based on the speed of the drive component. At the same time, the existing fixing structure for the inner and outer rings of the bearing is not convenient for fixing bearings of different sizes, resulting in relatively poor overall practicality.

[0012] This invention features a bearing outer ring fixing mechanism. Through the coordinated action of a transmission assembly, a nut block, and an arc-shaped fixing plate, this mechanism enables rapid fixing and stable clamping of bearing outer rings of different sizes. The motor in the transmission assembly drives the screw to rotate, achieving bidirectional adjustment via bevel gear transmission. The nut block moves the arc-shaped fixing plate, utilizing anti-slip textures to increase friction and ensure the bearing outer ring does not loosen during testing. This design not only improves the reliability of the test but also reduces test errors caused by unstable fixing, thus enhancing the accuracy of fault diagnosis.

Anti-slip texture 25 is installed at the upper side of the arc-shaped fixing plates 23. By adopting the above technical solution, the transmission assembly 21 can drive the four sets of nut blocks 22 to move closer to each other. The four sets of nut blocks 22 moving closer to each other can drive the four sets of arc-shaped fixing plates 23 to move closer to each other. At the same time, the bearing outer ring body 3 is placed on the upper end of the platform 24. The anti-slip texture 25 on the side of the arc-shaped fixing plates 23 is used to fix the bearing outer ring body 3.
[0023] Specifically, the transmission assembly 21 includes a motor 211, a first screw 212, a first bevel gear 213, a second bevel gear 214, and a second screw 215. The motor 211 is mounted on the side of the fixed platform 1. The first screw 212 is mounted on the output end of the motor 211. A first bevel gear 213 is mounted on the surface of the center of the first screw 212. Two sets of second bevel gears 214 are meshed on the side of the first bevel gear 213. The second screw 215 is mounted on the side of the second bevel gear 214. A nut block is also included. 22 are threaded onto the surfaces of screw 1 212 and screw 215. By adopting the above technical solution, when motor 211 is turned on, motor 211 drives screw 1 212 to rotate through its output end. The rotation of screw 1 212 drives bevel gear 1 213 to rotate. The rotation of bevel gear 1 213 drives bevel gear 214 to rotate. The rotation of bevel gear 214 drives screw 215 to rotate. The rotation of screw 1 212 and screw 215 can drive the four sets of nut blocks 22 to move closer to each other.
[0024] Specifically, the two ends of the screw 212 are provided with two sets of external threads in opposite directions, and the two ends of the screw 215 are provided with the same external thread direction.

At the same time, the bearing outer ring body 3 is placed on the upper end of the platform 24. The anti-slip texture 25 on the side of the arc-shaped fixing plate 23 is used to fix the bearing outer ring body 3. Example 2
[0026] The difference between this embodiment and Embodiment 1 is that the bearing inner ring fixing mechanism 9 includes a fixing plate 91, an electric push rod 92, a fixing rod 93, a fixing column 94, a lifting plate 95, a hinge seat 96, a rotating plate 97, a second hinge seat 98, an arc-shaped abutment plate 99, and an anti-slip texture 910. The output end of the driving component 8 is provided with a fixing plate 91. A fixing rod 93 is provided on the lower side of the fixing plate 91. A fixing column 94 is provided at the lower end of the fixing rod 93. An electric push rod 92 is provided at the center of the upper end of the fixing column 94. The output end of the electric push rod 92 is provided with... The lifting plate 95 has a hinge seat 96 on its lower side, a rotating plate 97 at the lower end of the hinge seat 96, and a second hinge seat 98 at the lower end of the rotating plate 97. An arc-shaped abutment 99 is located on the side of the second hinge seat 98. A slot corresponding to the arc-shaped abutment 99 is formed on the side of the fixing column 94. The arc-shaped abutment 99 has anti-slip texture 910 on its side. By adopting the above technical solution, the bearing inner ring fixing mechanism 9 can quickly fix and release bearing inner rings of different sizes, ensuring the stability of the bearing inner ring during testing. The lifting function of the electric push rod 92 can adjust the position of the arc-shaped abutment 99, ensuring it fits tightly against the bearing inner ring. Simultaneously, the anti-slip texture 910 increases friction, preventing the bearing inner ring from sliding during testing.
[0027] Specifically, both the upper and lower ends of the rotating plate 97 are rotatably connected to the hinge seat 1 96 and the hinge seat 2 98 via pins. By adopting the above technical solution, the flexible rotation structure design of the rotating plate 97 allows the arc-shaped abutment plate 99 to better fit the surface of the bearing inner ring, further enhancing the fixing effect on the bearing inner ring. At the same time, this structure also facilitates the quick replacement of bearings of different sizes for testing, improving testing efficiency.
[0028] In this embodiment, when in use, the hydraulic cylinder 6 is activated, which drives the bearing inner ring fixing mechanism 9 to insert into the bearing inner ring body 4. The lifting function of the electric push rod 92 can adjust the position of the arc-shaped abutment plate 99 so that it fits tightly against the bearing inner ring. Then, the drive component 8 drives the bearing inner ring body 4 to rotate, and at the same time, the electric push rod 92 adjusts the position of the arc-shaped abutment plate 99 to ensure that it fits tightly against the bearing inner ring. During the test, the operating status of the bearing is monitored in real time by the monitoring equipment to achieve the diagnosis of bearing faults.
[0029] The working principle and usage process of this utility model are as follows: When using this utility model, the motor 211 is turned on. The motor 211 drives the screw 212 to rotate through its output end. The rotation of the screw 212 drives the bevel gear 213 to rotate, which in turn drives the bevel gear 214 to rotate. The rotation of the bevel gear 214 drives the screw 215 to rotate. The rotation of the screws 212 and 215 causes the four sets of nut blocks 22 to move closer together. The four sets of nut blocks 22 moving closer together causes the four sets of arc-shaped fixing plates 23 to move closer together. At the same time, the outer ring body 3 of the bearing is placed on the upper end of the platform 24, which facilitates the use of... The anti-slip texture 25 on the side of the arc-shaped fixing plate 23 is used to fix the outer ring body 3 of the bearing. The hydraulic cylinder 6 is activated, and the hydraulic cylinder 6 drives the inner ring fixing mechanism 9 of the bearing to be inserted into the inner ring body 4 of the bearing. The lifting function of the electric push rod 92 can adjust the position of the arc-shaped abutment plate 99 so that it fits tightly against the inner ring of the bearing. Then, the drive component 8 drives the inner ring body 4 to rotate. At the same time, the electric push rod 92 adjusts the position of the arc-shaped abutment plate 99 to ensure that it fits tightly against the inner ring of the bearing. During the test, the operating status of the bearing is monitored in real time by the monitoring equipment to realize the diagnosis of bearing faults.
