Description

Technical Field

[0001] The present invention belongs to the technical field of defect detection, and specifically refers to a bearing defect detection device. Background Art

[0002] A bearing is a core component that supports the rotation of a shaft in a mechanical system, reducing the movement resistance through rolling or sliding friction and extending the equipment life. Its core structure consists of four parts: an inner ring, an outer ring, rolling elements (balls or rollers), and a cage. Some bearings also include seals and lubricants. According to the type of rolling elements, bearings can be divided into ball bearings, roller bearings, and self-aligning bearings, etc.

[0022] During specific use, first install the bearing 5 onto the transmission and mounting system 2. After placing the bearing 5 on the mounting arm 208, start the expansion motor 213. The expansion motor 213 drives the expansion drive wheel 212 to rotate. The rotation of the expansion drive wheel 212 drives the horizontal sliding of the expansion transmission shaft 211. The horizontal sliding of the expansion transmission shaft 211 drives the horizontal sliding of the expansion sliding cavity 210. The horizontal sliding of the expansion sliding cavity 210 drives the horizontal sliding of the expansion rotating arm 209. Since the expansion rotating arm 209 is rotationally connected to the mounting arm 208, and the limiting turntable 207 restricts the mounting arm 208 to slide only on the circular plane of the limiting turntable 207, the horizontal sliding of the expansion rotating arm 209 will drive the mounting arm 208 to slide outward. Use the mounting arm 208 to support and fix the inner ring of the bearing 5. At the same time, start the pushing cylinder 403. The pushing cylinder 403 extends to push the slide table 404 towards the bearing 5. When the rubber wheel 406 is in close contact with the outer ring of the bearing 5, the pushing cylinder 403 stops working. Start driving the bearing 5. Start the transmission motor 202. The transmission motor 202 drives the transmission output wheel 203 to rotate. The rotation of the transmission output wheel 203 drives the transmission flywheel 204 to rotate through the belt 205. The rotation of the transmission flywheel 204 drives the transmission sleeve shaft 206 to rotate. The rotation of the transmission sleeve shaft 206 drives the limiting turntable 207 to rotate. The rotation of the limiting turntable 207 drives the mounting arm 208 and the inner ring of the bearing 5 to rotate together. At the same time, start the reverse motor 405. The reverse motor 405 drives the rubber wheel 406 to rotate. The rotation of the rubber wheel 406 drives the outer ring of the bearing 5 to rotate. When the rotational speeds of the inner and outer rings of the bearing 5 are stable, start detecting the bearing 5. Lower the height of the lifting platform 302 to make the contact rotating wheel 308 in close contact with the top of the bearing 5. At this time, the vibration energy of the bearing 5 will be transmitted to the detection element 303 through the contact rotating wheel 308 and the test lever 307. And due to the lever principle (i.e., power × power arm = resistance × resistance arm), the detection element 303 can detect stronger vibration energy, thereby improving the detection accuracy.
