Description
Technical Field
[0001] The present invention relates to the technical field of residual film recovery machines, and in particular to a rolling bearing health monitoring device for residual film recovery machines based on fault diagnosis. Background Art
[0002] Rolling bearings are precision mechanical components that convert the sliding friction between the rotating shaft and the shaft seat into rolling friction, thereby reducing friction losses. Rolling bearings are generally composed of four parts: inner ring, outer ring, rolling element and cage. The inner ring is used to match the shaft and rotate with the shaft; the outer ring is used to match the bearing seat and play a supporting role; the rolling element is evenly distributed between the inner ring and the outer ring with the help of the cage, and its shape, size and number directly affect the performance and life of the rolling bearing; the cage can make the rolling element evenly distributed, guide the rolling element to rotate and play a lubricating role; In the prior art, failure of the rolling bearings of the residual film recovery machine often causes the machine to stop production, resulting in reduced production efficiency and increased losses. However, these failures are often difficult to detect in the early stages and are only noticed when the failure is serious enough to affect the normal operation of the machine, making it easy to affect the use of the rolling bearings. At the same time, the flatness of the rolling bearings cannot be detected during health monitoring, resulting in the rolling bearings being unable to be connected to the residual film recovery machine when in use. Summary of the invention

A temperature sensor 5 is arranged on the upper surface of the workbench 1, and the temperature sensor 5 is fitted with the heat-conducting rod 4. By utilizing the fit between the heat-conducting lifting ring 33 and the rolling bearing 18, the heat of the rolling bearing 18 can be transferred to the heat-conducting lifting ring 33 and the heat-conducting rod 4. The temperature of the heat-conducting rod 4 can be detected by the temperature sensor 5, so as to know the temperature of the rolling bearing 18. A controller 8 is fixedly connected to the side surface of the workbench 1, and the controller 8 is electrically connected to the temperature sensor 5 and the vibration sensor 23. The data detected by the temperature sensor 5 and the vibration sensor 23 can be transmitted to the controller 8 by the controller 8, so as to facilitate the staff to detect the vibration and temperature of the rolling bearing 18.

When the rolling bearing 18 is fixed, the balance plate can be moved downward by sliding the balance plate and the second slide plate 16, so that the flat guide roller 17 can fit with the surface of the rolling bearing 18, and the first slide plate 15 can be driven by the first slide plate 15 to move the balance plate downward. Move forward so that the leveling guide roller 17 can roll on the surface of the rolling bearing 18. When the rolling bearing 18 is uneven, the leveling guide roller 17 is prone to jamming. According to the jamming of the leveling guide roller 17, the staff can detect and observe the flatness of the rolling bearing 18. The interior of the workbench 1 is slidably connected to the sorting and collecting box 10, and the interior of the sorting and collecting box 10 is fixedly connected to the third spring 11. The end of the third spring 11 away from the sorting and collecting box 10 is fixedly connected to the storage plate 12. The rolling bearing 18 to be detected is placed on the storage plate 12.

When the number of rolling bearings 18 continues to decrease, the storage plate 12 can be extended from the inside of the sorting and collecting box 10 by the third spring 11, so that the rolling bearings 18 can be taken out and used conveniently. The front surface of the workbench 1 is movably connected to the box door 6 through a hinge. The box door 6 is opened to make it convenient for the staff to take and test the rolling bearings 18.
