[0002] In the field of mechanical manufacturing, as a key component, the performance of a bearing directly affects the running accuracy and reliability of equipment. Bearing running-in refers to mutual grinding of surfaces of internal parts of a bearing through running under a specific working condition, so as to form a stable working state, which is an important link for ensuring the quality of the bearing.
[0003] Traditional bearing running-in monitoring has technical bottlenecks such as rough pre-tightening force control, single data collection and lagging data analysis. Meanwhile, existing bearing running-in monitoring platforms mostly adopt an independent module combination mode, and lack of cooperative linkage between monitoring units (such as temperature sensors and current sensors), so as to fail to form comprehensive judgment. For example, when a bearing overheats only through temperature sensor detection, the bearing may have been seriously worn, and the best intervention opportunity is missed. In addition, the power consumption analysis function of the traditional platform is weak, and the bearing abnormality cannot be early warned through power fluctuation, so as to cause lagging fault diagnosis.

[0016] Optionally, in some embodiments of the present application, the monitoring control module further comprises a data storage unit, the data storage unit is used for storing the data collected by the temperature sensor, the current sensor, the power consumption analysis unit and the vibration sensor, and marking in time sequence.

[0021] Optionally, in some embodiments of the present application, a pressure sensing gasket is arranged between the adjusting member and the main shaft, which detects the axial pre-tightening force of the tapered surface on the bearing in real time and transmits to the monitoring control module.

[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. It is understood that the drawings are only provided for reference and illustration purposes and are not used to limit the present application. The connection relationship shown in the drawings is only for the convenience of clear description and does not limit the connection method.
[0033] Specifically, if Figures 1-3 As shown, an embodiment of the present application provides a bearing autonomous running-in monitoring platform, which mainly includes a running-in drive module, a data acquisition and processing module, and a monitoring and control module, wherein the running-in drive module performs a running-in operation on the detection bearing 300, facilitates the support of the bearing, and facilitates the recording of data; the data acquisition and processing module records the data of the running detection bearing 300, processes the corresponding data, and completes the monitoring process; the monitoring and control module performs data management and control according to its data processing module, and controls the speed of the detection bearing 300 according to the generated data information.
[0034] Specifically, in the above-mentioned structural mode, the running-in drive module mainly includes a main shaft 100 and a driving member 200. The main shaft 100 is arranged on the output end of the driving member 200, and the main shaft 100 rotates according to the drive of the driving member 200. In the present application, the detection bearing 300 is sleeved on the outside of the main shaft 100, and the rotation of the main shaft 100 drives the rotation of the detection bearing 300. In the embodiment of the present application, the driving member 200 is configured as a DC motor, and the output end of the DC motor is sleeved with a belt, which connects the output end of the DC motor and the main shaft 100, so that the main shaft 100 is rotated by the drive of the driving member 200, which is convenient for the detection bearing 300 to perform a rotation test.
[0035] On the running-in drive module, in order to detect the fitting accuracy of the bearing 300, it is necessary to detect the installation pre-tightening degree of the bearing to judge the quality of the bearing. To detect this item, an adjusting part 400 is sleeved on the main shaft 100, and a conical surface 410 is formed at one end of the adjusting part 400. When the detection bearing 300 is sleeved on the main shaft 100, the conical surface 410 on the adjusting part 400 is abutted with the inner ring 320 of the bearing, so that the inner ring 320 of the detection bearing 300 is fixed and adjusted by the conical surface 410.
[0036] A fixing member 500 is arranged on the side of the detection bearing 300 relative to the adjusting member 400, and the fixing member 500 is connected to the main shaft 100, so that the detection bearing 300 is limited on the main shaft 100, and the adjusting member 400 can push the conical surface 410 to abut against the detection bearing 300.
[0037] In the embodiment of the present application, the adjusting member 400 comprises an adjusting nut, the adjusting nut is threadedly connected to the main shaft 100, a threaded groove matched with the adjusting nut is arranged on the main shaft 100, the adjusting nut is threadedly connected to the main shaft 100 through the threaded groove, an abutting surface 310 is formed on the inner ring 320 of the detection bearing 300 corresponding to the position of the conical surface 410, the conical surface 410 abuts against the abutting surface 310, and the conical surface 410 can be pushed to abut against the detection bearing 300 by rotating the adjusting nut, so as to realize the pre-tightening force adjustment of the detection bearing 300. Further, in order to ensure that the abutting force of the conical surface 410 against the detection bearing 300 is moderate, and avoid excessive abutting to cause bearing damage or insufficient abutting to cause bearing loosening, a pressure sensing gasket is arranged between the adjusting member 400 and the main shaft 100, the pressure sensing gasket detects the axial pre-tightening force of the conical surface 410 against the detection bearing 300 in real time and transmits the pre-tightening force data to a monitoring control module. The monitoring control module monitors the pre-tightening force data transmitted by the pressure sensing gasket according to a pre-set pre-tightening force threshold value, and triggers an alarm signal when the pre-tightening force exceeds or is lower than the threshold value, reminding the operator to adjust.
[0038] After the running-in driving device is completed, the data acquisition and processing module can be arranged to collect data of the detection bearing 300. In the embodiment of the present application, the data acquisition and processing module comprises a temperature sensor and a current sensor, the temperature sensor is arranged on the surface of the outer ring 330 of the detection bearing 300, and further can be arranged in close contact with the outer ring 330 of the detection bearing 300, for collecting temperature data of the bearing in real time. The arrangement of the temperature sensor can timely find the high temperature of the bearing caused by friction, and prevent damage caused by overheating of the bearing.
[0039] Meanwhile, the temperature sensor can detect the temperature of the rotating bearing, which is convenient for judging the bearing clearance matching condition through the change of the temperature. The process needs to be implemented in cooperation with the monitoring control module.
[0040] In the embodiment of the present application, the current sensor is electrically connected with the driving member 200, for monitoring the current value of the driving member 200 in the process of driving the main shaft 100 and the detection bearing 300 to rotate. The current value can reflect the load condition of the driving member 200 and the running state of the bearing, which is helpful to timely find the abnormal running of the bearing. The process also needs to be implemented in cooperation with the monitoring control module.
[0041] In the embodiment of the present application, in order to facilitate more comprehensive detection of the detection bearing 300, the data acquisition and processing module further comprises a power consumption analysis unit connected to the driving member 200, so that the power consumption analysis unit can calculate the power fluctuation value of the driving member 200.
[0042] In the above power consumption analysis unit, the expression used for the power of the driving member 200 is:
[0043] ΔP = |I x V - P0|
[0044] Where I is the real-time current value collected by the current sensor, V is the input voltage of the driving member 200, and P0 is the no-load reference power of the driving member 200; when ΔP continuously exceeds the set threshold, the torque abnormality alarm is triggered, and the setting of the process can make the ΔP value significantly increase when the bearing appears to be stuck, tightly assembled or lubrication failure, which can trigger the alarm 30-60 seconds earlier than the temperature / vibration signal.
[0045] In the embodiment of the present application, the data acquisition and processing module further comprises a vibration sensor arranged on the end surface of the outer ring 330 of the detection bearing 300, for collecting the radial vibration acceleration signal of the bearing. The setting of the vibration sensor can timely find the vibration abnormality of the bearing during operation, such as unbalance, looseness or damage. The monitoring control module pre-sets a vibration threshold, when the vibration amplitude continuously exceeds the threshold, an alarm signal will be triggered, and the driving member 200 will be controlled to slow down or stop to prevent further damage to the bearing. By combining the data of the temperature sensor, the current sensor, the power consumption analysis unit and the vibration sensor, the monitoring control module can realize comprehensive monitoring of the running state of the bearing, and ensure the safety and efficiency of the bearing running-in process.
[0046] In the above, for the monitoring control module, a data storage unit is included, which is used to store the data collected by the temperature sensor, the current sensor, the power consumption analysis unit and the vibration sensor, and these data are marked in time sequence for subsequent data analysis and fault tracing. Through the data storage unit, a complete bearing running-in history record can be formed, which provides strong data support for the quality control and performance analysis of the bearing. In addition, the data storage unit also supports data export and backup functions, ensuring the safety and traceability of the data.
[0047] Based on the above various modules, in the process of measuring the bearing speed and temperature in the present application, the corresponding related data are as follows:
[0048] Table 1: Whole shaft air running temperature rise test operation data
[0049] Serial number Set speed rpm / min Frequency Hz Current ± 2 A Running time min Bearing temperature ± 2 °C 1 500 8.65 1.5 20 26 2 1200 20.76 1.3 30 43 3 1900 32.87 1.3 30 47 4 2600 44.98 1.6 30 48.6 5 3500 60.55 1.42 30 45.3
[0050] In actual operation, for different detection bearings 300, when the corresponding detection bearing 300 related data deviates from the data in the above table, the driving member 200 can be slowed down or stopped, and whether the detection bearing 300 meets the corresponding standard is determined according to the degree of deviation of the data.
[0051] For the above data, parameter thresholds are preset in the monitoring control module, including temperature thresholds, current thresholds, and power fluctuation thresholds. The monitoring control module receives bearing temperature data collected by the temperature sensor, driving current data collected by the current sensor, and power fluctuation values calculated by the power consumption analysis unit in real time. When any one or more of these data exceeds the preset parameter threshold, the monitoring control module will immediately trigger an alarm signal and respond to this abnormal situation by controlling the driving member 200 to slow down or stop, thereby effectively preventing damage to the bearing due to overheating, overloading, or abnormal vibration. This real-time monitoring and early warning mechanism greatly improves the safety and reliability of the bearing running-in process.
[0052] The monitoring control module also includes a running-in parameter setting unit that allows users to preset the running-in speed curve, running-in time, and load gradient change rule according to actual needs. Through this setting, users can flexibly control the running-in process to ensure that the detection bearing 300 can be fully and reasonably tested under different working conditions. During the running-in process, the monitoring control module will synchronously receive various data from the data acquisition and processing module, and accurately control the driving member 200 according to the preset running-in parameters to realize the automation and intelligentization of the running-in process. In addition, the running-in parameter setting unit also supports the import and comparison of historical data, and users can further optimize the running-in parameters by comparing the running-in data of different batches or different types of bearings to improve the testing efficiency and accuracy of the bearings.
[0053] The above embodiments are only used to illustrate the technical method of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical method of the present application.
