Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of reliability testing of key components of mechanical equipment, and particularly relates to a rolling bearing wear fault processing device. Background Art
[0002] Valves are important industrial control devices, which are widely used in industrial fields such as petroleum and petrochemical, electric power, nuclear power, etc. They are used to block or connect the flow of media, or change the flow direction of the media, regulate the flow rate and pressure of the media in the pipeline, and ensure the normal operation parameters of the system. Shielded electric valves are a type of electric valve. Compared with general electric valves, they have the advantages of being fully enclosed, having a compact structure, and being small in size, and are widely used in harsh industrial environments such as high temperature, high pressure, and radiation environments.
[0003] Due to the harsh working environment, the failure rate of shielded electric valves is higher than that of general industrial electric valves. Among all components, the rolling bearing in the valve body is one of the components with the highest failure rate. Its common failures are divided into two categories: jamming and wear. For the bearing wear failure of shielded electric valves, there is currently no effective fault detection method. Usually, the valve is disassembled to check whether the valve has failed, and new faults may be introduced during the reassembly process after disassembly, reducing the reliability of the valve. Therefore, there is an urgent need for a detection technology that can effectively detect the wear failure of shielded electric valves.
[0004] It is known that the research and development of equipment fault detection technology generally needs to carry out fault simulation tests to master the fault laws and then obtain fault sensitive features. However, for the fault detection technology of shielded electric valves, the existing technology generally relies on reliability tests. Although the fault laws of a few valves can be mastered to a certain extent. However, the valve faults obtained in the valve reliability test are random, and it is difficult to obtain the valve fault laws of directional single faults. Therefore, it is necessary to manufacture directional single faults. Summary of the Utility Model
[0005] Aiming at the technical problem that the existing shielded valves need to manufacture bearing wear faults directionally, the utility model provides a rolling bearing wear fault processing device, which can simulate the bearing wear faults of the valves, so as to directionally simulate different degrees of bearing wear and obtain effective fault signals, laying a necessary technical foundation for the research and development of the fault detection technology of shielded electric valves.
[0006] The utility model is realized through the following technical solutions:
[0007] The utility model provides a processing device for the wear fault of a rolling bearing, comprising: a mounting bushing, a limiting shoulder is arranged in the middle of the mounting bushing, and both ends of the mounting bushing can be inserted into the inner ring of the bearing to be processed; a first clamping member, the first clamping member is provided with a concave cavity for mounting the outer ring of the bearing to be processed, and the first clamping member is provided with a through hole for a rotating drive shaft to pass through; a second clamping member, the second clamping member is provided with a concave cavity for mounting the outer ring of the bearing to be processed; a fixing connecting member, the fixing connecting member is used for connecting the first clamping member and the second clamping member; wherein, when the first clamping member and the second clamping member are connected, two bearings to be processed can be mounted at the corresponding ends of the mounting bushing, and the bearings to be processed are limited by the limiting shoulder.
[0008] It should be noted that the operating conditions of the shielding valve bearing during operation can be roughly divided into a normal state and a fault state. With the changes in the bearing material, structure, and the external environment it is in, the operating conditions of the bearing will also change. The reasons for the wear fault of the shielding electric valve bearing can be roughly divided into two categories. One category is metal material fatigue, poor component processing quality, insufficient lubrication, etc., and the other category is the relative friction of moving parts caused by improper assembly. When the bearing has a wear fault, the fitting accuracy decreases, the machine efficiency decreases, accompanied by phenomena such as deformation, vibration, and noise.
[0009] Therefore, when the bearing begins to show slight wear, if it can be detected in time and effective measures such as improving the lubrication conditions are taken, the degree of wear will no longer increase or the wear rate will be greatly reduced. However, if effective maintenance measures are not taken in time, over time, the bearing state will gradually evolve from slight wear to moderate or even severe wear until its performance fails to meet the designed specified functions, that is, failure occurs.
[0010] In view of this, the processing device for the wear fault of a rolling bearing provided by the utility model comprises a mounting bushing, a first clamping member, a second clamping member, and a fixing connecting member. A limiting shoulder is arranged in the middle of the mounting bushing, and both ends of the mounting bushing can be inserted into the inner ring of the bearing to be processed. The first clamping member is provided with a concave cavity for mounting the outer ring of the bearing to be processed, and the first clamping member is provided with a through hole for a rotating drive shaft to pass through. The second clamping member is provided with a concave cavity for mounting the outer ring of the bearing to be processed, and the fixing connecting member is used for connecting the first clamping member and the second clamping member.
[0011] During use, two bearings to be processed are respectively sleeved on the corresponding ends of the mounting bushings, so that the inner rings of the bearings to be processed are fixed on the mounting bushings. One bearing to be processed is respectively installed in the concave cavity of the first clamping member, and one bearing to be processed is installed in the concave cavity of the second clamping member. At the same time, the mounting bushing is in transmission connection with the rotary drive shaft, and the first clamping member and the second clamping member are fixedly connected through a fixed connecting member. An axial action is applied to the two bearings to be processed, and the two bearings to be processed are limited by the limiting shoulders, so that the two bearings to be processed can operate independently, and thus the two bearings to be processed are spaced apart and installed at the corresponding ends of the mounting bushing.
[0012] During processing, the rotary drive shaft is driven to rotate by the rotary driver, and then the mounting bushing is driven to rotate, so that the rotational speeds of the two bearings (bearing a to be processed and bearing b to be processed) are maintained at a certain speed, and they rotate clockwise and counterclockwise for T hours respectively. At the same time, there is no lubricating medium during the operation of the bearings, and the operation time of the two bearings to be processed and the axial dimensions before and after wear processing are respectively recorded. Then, one of the bearings to be processed (bearing a to be processed) is replaced, and a new bearing to be processed (bearing c to be processed) is installed, so that the same axial force is applied axially to the bearing, and the same rotational speed as before is maintained, and they rotate clockwise and counterclockwise for 2T hours respectively. At the same time, there is no lubricating medium during the operation of the bearings, and the operation time of the two bearings to be processed (bearing b to be processed and bearing c to be processed) and the axial dimensions before and after wear processing are respectively recorded. Finally, bearings with mild wear faults (bearing a to be processed), bearings with moderate wear faults (bearing c to be processed), and bearings with severe wear faults (bearing b to be processed) are obtained, that is, test pieces with three different wear degrees of mild, moderate, and severe are processed.
[0013] Therefore, the rolling bearing wear fault processing device provided by the present utility model can simulate the wear faults of valve bearings, so as to directionally simulate different degrees of bearing wear and obtain effective fault signals, laying a necessary technical foundation for the research and development of fault detection technologies for shielded electric valves.
[0014] In an alternative embodiment of the present application, the fixed connecting member is a bolt, which is convenient for connecting the first clamping member and the second clamping member, and at the same time is convenient for applying axial force to the bearing to be processed and adjusting the magnitude of the axial force.
[0015] In an alternative embodiment of the present application, the fixed connecting member is a double-headed bolt, and one end of the fixed connecting member is screwed to the first clamping member, and one end of the fixed connecting member can pass through the second clamping member movably and is fitted with a fastening nut.
[0016] In an alternative embodiment of the present application, a rotary driver is further included, and the rotary driver is fitted with a rotary drive shaft, and the rotary drive shaft can be in transmission connection with the mounting bushing, so as to linearly drive the mounting bushing to rotate.
[0017] In an alternative embodiment of the present application, in the working state, the mounting bushing is sleeved on the rotary drive shaft.
[0018] In an alternative embodiment of the present application, it further includes a fixing key. In the working state, the fixing key is arranged between the rotary drive shaft and the mounting bushing to fix the mounting bushing on the rotary drive shaft through the fixing key.
[0019] In an alternative embodiment of the present application, it further includes a mounting base, and the rotary drive is mounted on the mounting base to facilitate fixing the rotary drive.
[0020] In an alternative embodiment of the present application, the first clamping member is fixedly connected to the mounting base so that the relative positions of the rotary drive and the first clamping member are fixed.
[0021] In an alternative embodiment of the present application, at least two fixing connection members are provided to ensure the balance of the interaction force between the first clamping member and the second clamping member.
[0022] In an alternative embodiment of the present application, one end of the second clamping member for mounting the bearing to be processed can be sleeved outside one end of the first clamping member for mounting the bearing to be processed, so as to quickly connect the first clamping member and the second clamping member.
[0023] Compared with the prior art, the present utility model has the following advantages and beneficial effects:
[0024] The rolling bearing wear fault processing device provided by the present utility model includes a mounting bushing, a first clamping member, a second clamping member and a fixing connection member. A limiting shoulder is arranged in the middle of the mounting bushing, and both ends of the mounting bushing can insert the inner ring of the bearing to be processed.

After a set time, a new bearing to be processed is replaced for processing, and then test pieces with three different wear degrees of light, medium and heavy are processed.

[0047] Combined again Figure 1 , this embodiment further includes a mounting base 11, and the rotary driver 8 is mounted on the mounting base 11 to facilitate fixing the rotary driver 8.
[0048] Correspondingly, the first clamping member 4 is fixedly connected to the mounting base 11 to make the relative positions of the rotary driver 8 and the first clamping member 4 fixed.
[0049] It should be noted that at least two of the fixed connectors 6 are provided to ensure the balance of the interaction force between the first clamping member 4 and the second clamping member 5.
[0050] On this basis, one end of the second clamping member 5 for mounting the bearing 3 to be processed can be sleeved outside one end of the first clamping member 4 for mounting the bearing 3 to be processed, so as to quickly connect the first clamping member 4 and the second clamping member 5.
[0051] In summary, the rolling bearing wear fault processing device provided in this embodiment includes a mounting bushing 1, a first clamping member 4, a second clamping member 5, and a fixed connector 6. A limiting shoulder 2 is provided in the middle of the mounting bushing 1, and both ends of the mounting bushing 1 can be inserted into the inner ring of the bearing 3 to be processed. The first clamping member 4 is provided with a concave cavity for mounting the outer ring of the bearing 3 to be processed, and the first clamping member 4 is provided with a through hole for the rotation drive shaft 9 to pass through. The second clamping member 5 is provided with a concave cavity for mounting the outer ring of the bearing 3 to be processed, and the fixed connector 6 is used to connect the first clamping member 4 and the second clamping member 5.
[0052] During use, the two bearings 3 to be processed are respectively sleeved on the corresponding ends of the mounting bushing 1, so that the inner ring of the bearing to be processed is fixed on the mounting bushing 1. One bearing 3 to be processed is respectively mounted in the concave cavity of the first clamping member 4, and one bearing 3 to be processed is mounted in the concave cavity of the second clamping member 5. At the same time, the mounting bushing 1 is in transmission connection with the rotation drive shaft 9, and the first clamping member 4 and the second clamping member 5 are fixedly connected through the fixed connector 6.

At the same time, there is no lubricating medium during the operation of the bearings. The running times of the two bearings 3 to be processed and their axial dimensions before and after wear processing are respectively recorded. Then, one of the bearings 3 to be processed (the bearing 3a to be processed) is replaced, and a new bearing 3 to be processed (the bearing 3c to be processed) is installed, so that the same axial force is applied axially to the bearing, and the same rotation speed as before is maintained. They rotate clockwise and counterclockwise for 2T hours respectively. At the same time, there is no lubricating medium during the operation of the bearings. The running times of the two bearings (the bearing 3b to be processed and the bearing 3c to be processed) to be processed and their axial dimensions before and after wear processing are respectively recorded. Finally, the bearings with mild wear faults (the bearing 3a to be processed), the bearings with moderate wear faults (the bearing 3c to be processed), and the bearings with severe wear faults (the bearing 3b to be processed) are obtained, that is, test pieces with three different wear degrees of mild, moderate, and severe are processed.
[0054] Taking a certain DN65 shielded electric valve as an example for illustration, the initial bearings 1, 2, and 3 are the matching rolling bearings of a certain shielded electric valve of the same type and the same specification.
[0055] First, fix the outer rings of bearings 1 and 2 through the rolling bearing wear fault processing device provided in this embodiment. Connect the inner rings to the rotary drive shaft 9. Apply an axial force of 400N axially to the bearings. Adjust the rotational speed of the rotary drive 8 so that the rotational speed of the bearings remains at 50 r / min. Rotate in the forward and reverse directions for 5 hours each, while keeping no lubricating medium during the operation of the bearings. Record the running time of bearings 1 and 2 and their axial dimensions before and after wear processing respectively. After the processing is completed, replace bearing 1.
[0056] Then, replace bearing 3 to the original position of bearing 1. Similarly, fix the outer rings of bearings 2 and 3 through the rolling bearing wear fault processing device. Connect the inner rings to the rotary drive shaft 9. Apply the same axial force (400N) as in the previous processing axially to the bearings. Adjust the rotational speed of the motor so that the rotational speed of the bearings remains at 50 r / min. Rotate in the forward and reverse directions for 10 hours each, while keeping no lubricating medium during the operation of the bearings. Record the running time of bearings 2 and 3 and their axial dimensions before and after wear processing respectively. After the processing is completed, remove bearings 2 and 3.
[0057] Finally, after measuring the ball sizes of bearings 1, 2, and 3, it is determined that bearings 1, 3, and 2 are the test pieces for mild, moderate, and severe wear faults respectively, which are used as the test pieces for the corresponding wear degree tests in the subsequent fault simulation tests of the shielded electric valve to obtain the characteristic signals under different faults.
[0058] In summary, the rolling bearing wear fault processing device provided in this embodiment simulates the wear fault of the valve bearing, which is convenient for obtaining effective fault signals, and then mastering the wear fault law of the shielded valve bearing, obtaining sensitive characteristics that can be used for the detection of the valve bearing wear fault, realizing the non-disassembly detection of the shielded electric valve, and also facilitating targeted maintenance in the later stage.
