Description

Technical Field

[0001] The present application relates to the field of data processing technology, and in particular to a high-voltage micro-current bearing clearance control method and related devices. Background Art

[0002] Tapered bearings and angular contact bearings are widely used in mechanical transmission devices. Bearings play a vital role in mechanical transmission devices, and their main functions include supporting, reducing friction, bearing loads, and ensuring rotation accuracy. Bearings are important components to ensure high-precision rotation of the shaft. Correctly installed high-quality bearings can ensure smooth rotation of the shaft, reduce shaft vibration and swing, and ensure the accuracy and stability of the transmission system. Bearings are the direct bearers of shaft loads and bear axial and radial loads during shaft transmission. At the same time, bearings greatly reduce the working friction resistance of the shaft, reduce energy loss, improve transmission efficiency, and extend the service life of the transmission device. When the bearing is damaged, the shaft will lose stability and cannot transmit power normally, and may even cause the collapse of the entire transmission system. In short, bearings are indispensable key components in transmission equipment, and their performance directly affects the reliability, efficiency and life of the transmission equipment.

[0003] Unreasonable axial clearance will have many adverse effects on the life of the bearing: when the clearance is too large, the bearing will have a large axial displacement during operation, resulting in unstable fit between the shaft and the bearing seat, which will cause vibration and noise. Long-term vibration will accelerate the fatigue wear of the bearing components and reduce the life of the bearing; excessive bearing clearance will increase the axial movement of the shaft, reduce the rotation accuracy of the shaft, affect the working performance of the shaft, and accelerate the wear of the bearing and affect its service life.

[0004] When the bearing clearance is too small, the bearing will generate greater friction resistance during operation, causing serious heating of the bearing. High temperature will affect the hardness of the bearing material and accelerate wear, and will also affect the lubrication effect, further aggravating the damage to the bearing. If the bearing clearance is too small, the bearing may be stuck when the temperature changes or the shaft is subjected to axial force, and it will not be able to operate normally, causing the bearing to fail and cause serious damage to the equipment.

[0005] Unreasonable bearing clearance will significantly reduce the service life of the bearing. Therefore, when installing and using the bearing, the bearing clearance should be strictly controlled to ensure that it is within a reasonable range.

[0006] At present, when installing bearings, the measurement of bearing clearance often relies on manual dimensional measurement by assemblers. Environmental factors, operator techniques and methods have a great influence on the bearing clearance measurement during the operation of the assemblers, resulting in large measurement errors, large randomness in the distribution of measurement errors, high work intensity and low work efficiency.

[0061] 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 in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0062] The terms "first", "second", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0063] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0064] In order to better understand the high-voltage micro-current bearing clearance control method provided in the embodiment of the present application, the existing bearing clearance control method is first briefly introduced below. In the existing scheme, the design of the bearing clearance will directly affect the service life of the bearing. When the bearing clearance is too large, the bearing will produce a large axial displacement during operation, resulting in an unstable fit between the shaft and the bearing seat, thereby causing vibration and noise. Long-term vibration will accelerate the fatigue wear of the bearing components and reduce the life of the bearing; excessive bearing clearance will increase the axial movement of the shaft, reduce the rotation accuracy of the shaft, affect the working performance of the shaft, and also accelerate the wear of the bearing and affect its service life.

[0065] When the bearing clearance is too small, the bearing will generate greater friction resistance during operation, causing serious heating of the bearing. High temperature will affect the hardness of the bearing material and accelerate wear, and will also affect the lubrication effect, further aggravating the damage to the bearing. If the bearing clearance is too small, the bearing may be stuck when the temperature changes or the shaft is subjected to axial force, and it will not be able to operate normally, causing the bearing to fail and cause serious damage to the equipment.

[0066] At present, when installing bearings, the measurement of bearing clearance often relies on manual dimensional measurement by assemblers. Environmental factors, operator techniques and methods have a great influence on the bearing clearance measurement during the assembler's operation. The measurement error is large, and the distribution of measurement error is highly random, resulting in low accuracy when adjusting the bearing clearance.

[0067] In order to solve the above-mentioned problems, an embodiment of the present application provides a high-voltage micro-current bearing clearance control method, which can collect the current clearance of the target bearing after it is placed in a rotating state, and adjust it when it is not in compliance, thereby improving the accuracy of bearing clearance control.

[0068] The high voltage micro-current bearing clearance control method provided in the embodiment of the present application can collect the relevant clearance through the bearing clearance collection device. Figure 1 As shown, the bearing clearance acquisition device includes a power supply 1, a bearing clearance adjustment ring 2, and a measuring module 3, wherein the power supply 1 is connected to the outer ring of the bearings installed back to back, and the measuring module 3 is connected to the bearings installed back to back. The bearing clearance adjustment ring 2 is used to adjust the clearance between the bearings.

[0069] See also Figure 2 , Figure 2 A schematic flow chart of a high voltage micro-current bearing clearance control method is provided for the embodiment of the present application. Figure 2 As shown, the high voltage micro-current bearing clearance control method includes:

[0070] 201. Determine a compliance clearance range of the target bearing according to usage scenario information of the target bearing.

[0071] Among them, the usage scenario information can be understood as what kind of equipment the target bearing is installed on, as well as the operating scenario of the equipment, etc. Since the bearing plays a vital role in the mechanical transmission device during operation, its main functions include support, friction reduction, load bearing, and rotation accuracy. However, due to different usage scenarios, the requirements for friction, load bearing, rotation accuracy, etc. faced by bearings are also different. Therefore, the compliance gap interval can be determined based on the corresponding load bearing, rotation accuracy, etc. in the usage scenario information. Specifically, a template can be generated through a preset compliance interval, and the load bearing and rotation accuracy can be set to the relevant parameter positions in the compliance interval generation template to obtain the compliance gap interval.

[0072] In a possible implementation, a method of determining a compliance clearance interval of a target bearing according to usage scenario information of the target bearing includes:

[0073] A1. Determine temperature information, humidity information, and load information of the target bearing when in use according to the usage scenario information;

[0074] A2. Determine a compliance clearance interval of the target bearing according to the temperature information, the humidity information and the load information.

[0075] Among them, the bearing information can be understood as load information, and the temperature information and humidity information can characterize the use environment faced by the bearing during use. Both have a greater impact on the bearing. Therefore, the temperature information, humidity information and load information can be used to determine the compliance clearance range.

[0076] Specifically, the compliance gap interval of the target bearing may be determined by mapping the preset temperature information, humidity information, load information and the compliance gap interval. Of course, it may also be determined by using a preset compliance gap interval determination model, using temperature information, humidity information and the load information to determine the compliance gap interval. The preset compliance gap interval determination model is a pre-trained model for determining the compliance gap interval.

[0077] 202. After the installed target bearing is placed in a rotating state, a bearing clearance acquisition device is used to obtain a current clearance of the target bearing by means of a high voltage micro-current.

[0078] Specifically, during the measurement process, the target bearing is in a rotating state, which can reduce the impact of bearing eccentricity and eccentric load on the measurement accuracy of bearing clearance. This measurement method facilitates full automation, and the bearing clearance measured by this method is the actual value of the bearing in the final state of the mechanical equipment. The difference between the measured clearance value and the actual clearance caused by the assembly process after measurement is eliminated from the root, and the accuracy of the current clearance of the bearing obtained by subsequent measurement is improved.

[0079] In a possible implementation, a method for obtaining the current clearance of a bearing by using a bearing clearance acquisition device using a high voltage micro current comprises:

[0080] B1. Acquire, by the bearing clearance acquisition device, the power supply voltage applied to the bearing outer ring of the target bearing in a rotating state, the measured voltage of the power supply voltage passing through the bearing outer ring, and the current value flowing between the bearings;

[0081] B2. determining a voltage difference according to the power supply voltage and the measured voltage;

[0082] B3, determining an equivalent resistance value according to the voltage difference and the current value;

[0083] B4. Determine the current gap according to the equivalent resistance value.

[0084] For details, please refer to Figure 1The bearing clearance acquisition device shown in the figure is used to acquire the power supply voltage of the bearing outer ring of the target bearing, the measured voltage of the power supply voltage passing through the bearing outer ring, and the current value flowing through the bearing. When applying the power supply voltage, high voltage and low current can be applied, so as to ensure safety during measurement.

[0085] The difference between the power supply voltage and the measured voltage can be determined as the voltage difference. The equivalent resistance value can be determined by the product of the voltage difference and the DC current value. Since different equivalent resistance values ​​correspond to different bearing clearances, the current clearance can be determined according to the equivalent resistance value. Specifically, determining the current clearance according to the equivalent resistance value includes:

[0086] C1. Obtaining the collection accuracy information of the bearing clearance collection device;

[0087] C2. Correcting the equivalent resistance value according to the acquisition accuracy information to obtain a corrected equivalent resistance value;

[0088] C3. Determine the current gap using the corrected equivalent resistance value.

[0089] Due to the limitation of the acquisition accuracy of the acquisition device, the accuracy of the equivalent resistance value calculated by the voltage and current values ​​collected by the acquisition device will also be affected. Therefore, the equivalent resistance value can be corrected according to the acquisition accuracy information to obtain the corrected equivalent resistance value. Specifically, the correction factor can be determined according to the acquisition accuracy information, and the product of the correction factor and the equivalent resistance value is determined as the corrected equivalent resistance value. Different acquisition progress information corresponds to different correction factors. Therefore, the correction factor can be determined according to the acquisition accuracy information of the bearing clearance acquisition device.

[0090] 203. If the current clearance is not within the compliant bearing clearance interval, determine a bearing clearance adjustment parameter according to the current clearance and the compliant bearing clearance interval.

[0091] If the current clearance is not within the compliant bearing clearance range, there is no need to adjust the clearance of the target bearing.

[0092] Specifically, a method for determining a bearing clearance adjustment parameter according to the current clearance and the compliant bearing clearance interval includes:

[0093] D1. Obtaining the deviation between the current clearance and the compliant bearing clearance interval;

[0094] D2. Obtain lubricating grease parameters and bearing manufacturer parameters when installing the target bearing;

[0095] D3. Determine the clearance adjustment parameter adjustment factor according to the lubricating grease parameters and the bearing manufacturer parameters;

[0096] D4. Determine the bearing clearance adjustment parameter according to the deviation and the clearance adjustment parameter adjustment factor.

[0097] The deviation between the clearance before extraction and the compliant bearing clearance interval may be the difference between the left endpoint and the right endpoint of the current clearance and the compliant bearing clearance interval, and the endpoint corresponding to the difference with the smaller absolute value of the difference may be determined as the target interval point, and the absolute value of the difference between the target interval point and the current clearance may be determined as the deviation. If the target interval point is the left endpoint, the deviation is negative, and if the target interval point is the right endpoint, the deviation is positive.

[0098] Since the lubricating grease parameters and bearing manufacturer parameters have certain uniqueness, for example, different bearing manufacturers have different use procedures for their bearings, and different lubricating greases may also result in certain differences in the clearance between the bearings. Therefore, the clearance adjustment parameter adjustment factor can be determined based on the bearing manufacturer parameters and lubricating grease parameters.

[0099] The product of the deviation and the clearance adjustment parameter adjustment factor can be determined as the bearing clearance adjustment parameter, thereby improving the accuracy of determining the bearing clearance adjustment parameter.

[0100] 204. Use the bearing clearance adjustment parameter to adjust the clearance of the target bearing to obtain an adjusted target bearing.

[0101] If the clearance adjustment parameter is positive, the bearing clearance value corresponding to the clearance adjustment parameter is reduced; if the clearance adjustment parameter is negative, the bearing clearance value corresponding to the clearance adjustment parameter is increased, thereby obtaining the adjusted target bearing.

[0102] In this example, the compliant clearance interval of the target bearing is determined based on the usage scenario information of the target bearing. After the installed target bearing is placed in a rotating state, the current clearance of the target bearing is obtained by a bearing clearance acquisition device using a high voltage microcurrent. If the current clearance is not within the compliant bearing clearance interval, a bearing clearance adjustment parameter is determined based on the current clearance and the compliant bearing clearance interval. The clearance of the target bearing is adjusted using the bearing clearance adjustment parameter to obtain an adjusted target bearing. Therefore, the current clearance of the target bearing after being placed in a rotating state can be acquired and adjusted when it is not compliant, thereby improving the accuracy of bearing clearance control.

[0103] In a specific implementation, a high voltage micro-current bearing clearance control method is also adopted, as follows:

[0104] To achieve the above object, the present invention provides the following technical solution: a tapered bearing and angular contact bearing clearance control device based on high voltage and small current includes:

[0105] High voltage and low current power supply. The advantage of choosing high voltage and low current power supply is that higher measurement resolution can be obtained while ensuring personnel safety.

[0106] Voltage measurement device; used to measure the voltage change after the power passes through the inner and outer rings of the mechanically assembled bearing, and indirectly measure the bearing clearance.

[0107] Connecting device between power supply and voltage measuring device and device under test: used for effective and reliable connection between power supply, device under test and measuring device.

[0108] The difference in bearing clearance causes a change in the resistance of the bearing (outer ring - rolling element - inner ring). The change in bearing resistance is measured by voltage change, which is ultimately reflected in the assembly clearance of the bearing. At the same time, the lubrication condition of the bearing in its initial state can be checked.

[0109] Compared with the existing bearing clearance measurement method, the bearing is in a rotating state during the measurement process, which can reduce the influence of bearing eccentricity and eccentric load on the measurement accuracy of bearing clearance. This measurement method is convenient for fully automated operation. The bearing clearance measured by this method is the actual value of the bearing in the final state of the mechanical equipment. The difference between the measured clearance value and the actual clearance caused by the assembly process after measurement is eliminated from the root.

[0110] When actually measuring the bearing clearance, first pre-tighten it through the bearing clearance adjustment ring, then rotate the hub assembly, and rotate the bearing clearance adjustment ring to make the measured value match the calibration value and realize the bearing clearance adjustment. The calibration value includes the bearing manufacturer, lubricating grease parameters, temperature and other parameters. The bearing clearance control device realizes unmanned bearing clearance measurement and adjustment, and records the bearing assembly clearance data.

[0111] The power supply of this control solution adopts a high-frequency, high-voltage, micro-current sinusoidal power supply. The power supply is connected to the outer ring of the tapered roller bearing used in pairs through a wire. The size of the bearing gap produces a change in resistance. The change in resistance produces a voltage drop. The power supply voltage is compared with the voltage difference after passing through the paired tapered bearings. The corresponding relationship between the voltage difference and the bearing gap is compared with the voltage difference and the calibration curve through a computer, thereby outputting the measured gap of the paired tapered bearings.

[0112] U c =U 0 -U i

[0113] U i =R i I i

[0114] Among them, U c is the measured voltage. 0 is the power supply voltage, Ui U is the voltage drop between the outer rings of the assembled tapered bearings when the current passes through them. i To measure voltage, R i is the equivalent resistance of the bearing clearance, I i is the current during measurement.

[0115] The invention is used to measure the clearance of tapered bearings after being installed in pairs. It has high measurement accuracy, measurement resolution up to micron level, stable measurement data, and can also provide feedback on the impact of assembly links on bearing clearance. The measured bearing clearance has a high degree of consistency with the actual use clearance of the bearing, and it is convenient to implement assembly adjustment measurement closed-loop automation.

[0116] For the above embodiments, please refer to Figure 3 , Figure 3 A schematic diagram of the structure of a terminal provided in an embodiment of the present application, such as Figure 3 As shown, it includes a processor, an input device, an output device and a memory, which are connected to each other, wherein the memory is used to store a computer program, the computer program includes program instructions, the processor is configured to call the program instructions, and the program includes instructions for executing the following steps;

[0117] Determine the compliance clearance range of the target bearing based on the usage scenario information of the target bearing;

[0118] After the mounted target bearing is placed in a rotating state, the current clearance of the target bearing is obtained by a bearing clearance acquisition device using a high voltage micro-current method;

[0119] If the current clearance is not within the compliant bearing clearance interval, determining a bearing clearance adjustment parameter according to the current clearance and the compliant bearing clearance interval;

[0120] The clearance of the target bearing is adjusted using the bearing clearance adjustment parameter to obtain an adjusted target bearing.

[0121] In this example, the compliant clearance interval of the target bearing is determined based on the usage scenario information of the target bearing. After the installed target bearing is placed in a rotating state, the current clearance of the target bearing is obtained by a bearing clearance acquisition device using a high voltage microcurrent. If the current clearance is not within the compliant bearing clearance interval, a bearing clearance adjustment parameter is determined based on the current clearance and the compliant bearing clearance interval. The clearance of the target bearing is adjusted using the bearing clearance adjustment parameter to obtain an adjusted target bearing. Therefore, the current clearance of the target bearing after being placed in a rotating state can be acquired and adjusted when it is not compliant, thereby improving the accuracy of bearing clearance control.

[0122] The above mainly introduces the scheme of the embodiment of the present application from the perspective of the execution process on the method side. It is understandable that in order to realize the above functions, the terminal includes a hardware structure and / or software module corresponding to the execution of each function. Those skilled in the art should easily realize that, in combination with the units and algorithm steps of each example described in the embodiments provided herein, the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to be beyond the scope of this application.

[0123] The embodiment of the present application can divide the terminal into functional units according to the above method example. For example, each functional unit can be divided according to each function, or two or more functions can be integrated into one processing unit. The above integrated unit can be implemented in the form of hardware or in the form of software functional units. It should be noted that the division of units in the embodiment of the present application is schematic and is only a logical function division. There may be other division methods in actual implementation.

[0124] In line with the above, see Figure 4 , Figure 4 The present invention provides a schematic structural diagram of a high voltage micro-current bearing clearance control device. Figure 4 As shown, the device comprises:

[0128] The adjustment unit 404 is used to adjust the clearance of the target bearing using the bearing clearance adjustment parameter to obtain an adjusted target bearing.

[0129] In this example, the compliant clearance interval of the target bearing is determined based on the usage scenario information of the target bearing. After the installed target bearing is placed in a rotating state, the current clearance of the target bearing is obtained by a bearing clearance acquisition device using a high voltage microcurrent. If the current clearance is not within the compliant bearing clearance interval, a bearing clearance adjustment parameter is determined based on the current clearance and the compliant bearing clearance interval. The clearance of the target bearing is adjusted using the bearing clearance adjustment parameter to obtain an adjusted target bearing. Therefore, the current clearance of the target bearing after being placed in a rotating state can be acquired and adjusted when it is not compliant, thereby improving the accuracy of bearing clearance control.
