Description

Technical Field

[0001] This invention relates to the field of rolling mill bearing housing technology, and more specifically to a wear-resistant strengthening system for rolling mill bearing housing. Background Technology

[0002] Roll bearing housings are a key mechanical component in rolling mills (such as steel plate, strip, and section steel production lines). Essentially, they are load-bearing and positioning units. Their core function is to install and support roll bearings, thereby accurately and stably supporting the rolls and transmitting rolling force from the rolls to the mill stand. Roll bearing housings are the "joints" and "foundation" of rolling equipment. Although they do not directly participate in deformation or drive like rolls or motors, their performance directly determines whether the rolling mill can operate stably.

[0003] Lubricating oil is placed between the bearing housing and the bearing in the rolling mill. This effectively increases the wear resistance of the bearing housing and the service life of the bearing. However, if there is insufficient lubricating oil in the bearing housing, the friction between the bearing and the bearing housing will generate a lot of heat, causing the temperature to rise sharply. The poor circulation cooling effect will lead to a decrease in rolling accuracy. If there is too much lubricating oil in the bearing housing, the excess grease or lubricating oil will be violently agitated by the high-speed rotating bearing, generating huge internal frictional heat. The temperature will continue to rise, leading to seal failure and premature bearing fatigue. Therefore, to enhance the wear resistance between the bearing housing and the bearing, it is necessary to strictly control the amount of lubricating oil inside the bearing housing.

[0004] A search revealed that Chinese invention patent application number 201811062853.2 provides a roll bearing housing, including a bearing mounting device and an oil-air mixing lubrication device. The bearing mounting device is provided with a mounting shell, and the mounting shell is provided with an elastic colloid layer, a cooling water cavity and a bearing mounting cavity arranged sequentially from the outside to the inside. The oil-air mixing lubrication device includes an oil-air mixer, which is located in the lower part of the bearing mounting cavity.

[0005] The above-mentioned patent has the following shortcomings: it cannot monitor the temperature of the bearing inside the bearing housing, and it cannot know whether the lubricating oil is too much or too little under the current working conditions. Therefore, a wear-resistant strengthening system for rolling mill roll bearing housing is proposed. Summary of the Invention

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a wear-resistant strengthening system for rolling mill roll bearing housing, which can effectively solve the existing problems.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] This invention provides a wear-resistant strengthening system for rolling mill roll bearing housings, comprising a bearing housing, a detection unit, a storage unit, a calculation unit, and an execution unit. The detection unit includes six temperature probes and a thermometer. The six temperature probes are circumferentially distributed on the outer wall of the bearing housing for detecting the outer wall temperature T of the bearing housing. i The thermometer is installed outside the bearing housing and is used to detect the external ambient temperature T. w The storage unit is used to record data from the detection unit and the processing unit, as well as the input parameter set P.

The automatic oil inlet mechanism and the automatic oil outlet mechanism are respectively arranged on both sides of the bearing housing. The execution unit is used to perform one of the following operations: injecting lubricating oil into the bearing housing, exporting lubricating oil from the bearing housing, maintaining the current state of the rolling mill and stopping the operation of the rolling mill driver.

[0009] Furthermore, the parameter set P includes the initial bearing temperature T0, the thickness d of the bearing housing ring wall, the convective heat transfer coefficient h of the bearing housing outer surface, the outer radius R0 of the bearing housing shell, and the inner radius R of the bearing housing shell. n The thermal conductivity K of the bearing housing shell h Lubricating oil equivalent thermal resistance R g Standard range of external wall temperature difference △T E Standard value of bearing temperature difference T cE and the standard value t of temperature difference time E The bearing housing wear-resistant strengthening system further includes the following steps:

[0011] S2: The detection unit detects the temperature on the outer wall of the bearing housing at unit time intervals Δt and transmits the data to the storage unit. The calculation unit calculates the outer wall temperature difference ΔT and compares it with the standard range ΔT for outer wall temperature differences. E For comparison, when the external wall temperature difference ΔT ∈ the standard range of external wall temperature difference ΔT E If the condition is met, proceed to S3; otherwise, the execution unit will stop the mill driver operation.

[0012] S3: Average temperature T of the outer wall of the arithmetic unit p And calculate the instantaneous temperature T of the bearing. z And based on the instantaneous temperature T of the bearing z Calculate the bearing temperature difference T from the initial bearing temperature T0. c The bearing temperature difference T c Standard value of bearing temperature difference T cE Comparison, when the bearing temperature difference T c >Standard value of bearing temperature difference T cE If the current condition is met, proceed to S4; otherwise, the execution unit will perform the mill maintain status quo operation.

[0013] S4: The arithmetic unit calculates the bearing instantaneous temperature T based on two consecutive measurements. z Calculate the time t of the temperature difference, and compare the time t of the temperature difference with the standard value t of the temperature difference. E For comparison, when the temperature difference time t < the standard value of the temperature difference time t E When the temperature difference time t ≥ the standard value of the temperature difference time t, proceed to S5. E Then, switch to S6;

[0023] Beneficial effects

[0024] The technical solution provided by this invention has the following advantages compared with known public technologies:

[0025] The temperature of the outer wall of the bearing housing is detected by multiple temperature probes. Then, the temperature difference between the outer wall and the temperature difference between the points is calculated by the calculation unit. If the temperature difference exceeds 5%, it may indicate that there is insufficient lubrication in the bearing housing or that the load is severely uneven, requiring shutdown for maintenance. Then, the instantaneous temperature of the bearing is calculated and compared with the initial temperature of the bearing. If the temperature difference is not large, it means that the rolling mill is operating normally. If the temperature difference is large, it means that there is too much or too little lubricating oil. Next, the calculation unit calculates the time of temperature difference and calculates the condition of the lubricating oil in the bearing housing by whether the temperature rises continuously (too much lubricating oil) or rises suddenly (too little lubricating oil). Then, the lubricating oil is increased or decreased by the automatic oil inlet mechanism or the automatic oil outlet mechanism to ensure that the lubricating oil inside the bearing housing is always suitable for the current working conditions and enhances the wear resistance of the bearing housing.

[0036] Example:

[0037] A wear-resistant strengthening system for rolling mill roll bearing housings, such as Figure 1 , Figure 2 As shown, the system includes a bearing housing 1, a detection unit, a storage unit, a processing unit, and an execution unit. The detection unit includes multiple temperature probes 2 and a thermometer. The multiple temperature probes 2 are distributed in a circumferential shape on the outer wall of the bearing housing 1 to detect the outer wall temperature T of the bearing housing 1. i The thermometer is installed outside the bearing housing 1 and is used to detect the external ambient temperature T. w It is worth noting that the number of temperature probes 2 is preferably 6. By detecting the temperature of the outer wall of the bearing housing 1, the internal temperature of the bearing housing 1 can be estimated. The working condition of the lubricating oil inside the bearing housing 1 can be estimated by the temperature. Then, targeted adjustments can be made to ensure a good working environment between the bearing housing 1 and the bearing. The temperature probes 2 measure the temperature of the outer wall of the bearing housing 1 at the same time interval, which can detect temperature abnormalities in time and facilitate adjustment. The preferred time interval is 10 seconds per unit time Δt.

[0038] The storage unit is used to record data from the detection unit and the processing unit, as well as the input parameter set P. The storage unit records the outer wall temperature T at unit time intervals Δt. i and external ambient temperature T w It should be noted that the parameter set P includes the initial bearing temperature T0, the thickness d of the annular wall of bearing housing 1, the convective heat transfer coefficient h of the outer surface of bearing housing 1, the outer radius R0 of the outer shell of bearing housing 1, and the inner radius R of the outer shell of bearing housing 1. n The thermal conductivity K of the outer shell of bearing housing 1 h Lubricating oil equivalent thermal resistance R g Standard range of external wall temperature difference △T E Standard value of bearing temperature difference T cE and the standard value t of temperature difference time E Among them, the initial bearing temperature T0, the thickness d of the annular wall of bearing housing 1, the outer radius R0 of the outer shell of bearing housing 1, and the inner radius R of the outer shell of bearing housing 1 are... n The specific values ​​of the workpiece are input into the system by measuring them, including the convective heat transfer coefficient h of the outer surface of bearing housing 1 and the thermal conductivity K of the outer shell of bearing housing 1. h Lubricating oil equivalent thermal resistance R g You can input the corresponding material, and the system's cloud database will look up the corresponding value, while the standard range of external wall temperature difference △T E Standard value of bearing temperature difference T cE and the standard value t of temperature difference time E This requires staff to set it up themselves according to their work environment, making the system more flexible and more widely applicable;

[0039] The calculation unit is used to generate the outer wall temperature difference ΔT based on the data from the detection unit and the preset mapping relationship M1, and the calculation unit is used to generate the average outer wall temperature T of the bearing housing 1 based on the data from the detection unit and the preset mapping relationship M2. p The computing unit is used to calculate the data from the detection unit and the average temperature T of the outer wall. p The parameter set P and the preset mapping relationship M3 are used to generate the instantaneous bearing temperature T. z The processing unit is used to generate the bearing temperature difference T based on the data from the detection unit and the preset mapping relationship M4. c The computing unit is used to calculate the bearing temperature difference T. c The parameter set P and the preset mapping relationship M5 are used to generate the temperature difference time t. Specifically, the outer wall temperature difference ΔT represents the temperature difference between various points. If the temperature difference is large, it indicates that bearing housing 1 may have eccentric friction, local lubrication deficiency, gear meshing imbalance, or cooling system failure. In this case, the machine needs to be stopped and the cause needs to be found by the staff. The average temperature T of the outer wall is... pUsed to calculate the temperature inside bearing housing 1, i.e., the instantaneous temperature T of the bearing. z Bearing temperature difference T c Used to detect whether the bearing housing is overheated. If the bearing temperature difference T c Belongs to the standard value T of bearing temperature difference cE If the temperature difference T is within the range, it indicates that the rolling mill is in good working condition and the lubricating oil inside bearing housing 1 is adequate. c Significantly greater than the standard value T for bearing temperature difference cE This indicates that the temperature rise is caused by the amount of lubricating oil inside the bearing housing being unsuitable for the current operating conditions, requiring adjustment of the lubricating oil quantity. At this point, the difference in time t is calculated, and the temperature difference is compared with the standard value t0. E By comparison, if the temperature rises suddenly, it means that there is not enough lubricating oil and lubricating oil needs to be added to the bearing housing 1. If the temperature rises continuously, it means that there is too much lubricating oil and lubricating oil needs to be drained from the bearing housing 1.

[0040] The execution unit includes an automatic oil inlet mechanism 3, an automatic oil outlet mechanism 4, and a mill drive. The automatic oil inlet mechanism 3 and the automatic oil outlet mechanism 4 are respectively disposed on both sides of the bearing housing 1. The execution unit is used to perform one of the following operations: injecting lubricating oil into the bearing housing 1, discharging lubricating oil from the bearing housing 1, maintaining the current state of the mill, and stopping the operation of the mill drive. It should be understood that the functions of the automatic oil inlet mechanism 3 and the automatic oil outlet mechanism 4 on the bearing housing 1 are mainly to add lubricating oil to the bearing housing 1 and to discharge lubricating oil from the bearing housing 1. These are existing technologies and will not be described in detail here.

[0041] In the preferred scheme with 6 temperature probes 2, the mapping relationship M1 for calculating the outer wall temperature difference ΔT is as follows: ;

[0042] Among them, T k T j Six outer wall temperatures T i one of the;

[0043] Laboratory tests showed that a temperature difference greater than 5% at any point on bearing housing 1 indicates internal temperature imbalance. Therefore, the preferred standard range for external wall temperature difference is ΔT. E The value is 0.95-1.05, when the outer wall temperature difference ΔT does not fall within the standard range of outer wall temperature difference ΔT. E At that time, the execution unit performs a stop mill drive operation;

[0044] Average temperature of outer wall T p Mapping relationship M2 is ,

[0045] For the instantaneous temperature T of the bearing zThe mapping relationship is derived as follows: First, from the average temperature T of the outer wall of bearing housing 1... p Calculate the inner wall temperature T of the outer casing h Formulas were derived based on the temperature distribution inside the casing, the heat flow through the casing, and the heat dissipation conditions of the outer wall. These formulas were then combined to obtain the solution. Next, the heat flux density q of the outer shell is calculated. By determining the temperature distribution constant, calculating the radial temperature gradient, and applying Fourier's law, the heat flux density at the inner wall is finally calculated. Finally, assuming the heat flux density on the shaft surface and the inner wall of the outer shell are the same, it can be deduced that... Therefore, T c =T h +qR g Substitute and obtain ;

[0046] Bearing temperature difference T c Mapping relationship M4 is T c =T z -T0, Under normal circumstances, the operating temperature of a bearing is 45-60℃. If the operating temperature of the bearing exceeds 80℃, it indicates that the bearing is not operating normally. Therefore, the preferred standard value for bearing temperature difference is T0. cE The bearing temperature difference is 20℃. c <Standard value of bearing temperature difference T> cE If the bearing is in good condition, it means the bearing is working properly; otherwise, it means the bearing is not working properly and the lubricating oil inside the bearing housing 1 needs to be adjusted.

[0047] The mapping relationship M5 for temperature difference time t is as follows , among which, T n+1 The instantaneous bearing temperature T is currently generated. z T n The bearing instantaneous temperature T generated last time z Since the unit time Δt is a fixed value, a large temperature difference t indicates a rapid temperature change, meaning the temperature has risen suddenly, which aligns with insufficient lubricating oil. In this case, lubricating oil needs to be added to bearing housing 1. Conversely, a small temperature difference t indicates a slow temperature change, meaning the temperature has risen continuously, which aligns with excessive lubricating oil. In this case, lubricating oil needs to be drained from bearing housing 1. This is achieved by setting a standard temperature difference value t. E The preferred standard value of temperature difference time t E The value is 2 because the standard value of bearing temperature difference T cE The critical point is when the temperature rises by 20°C within 10 seconds.

[0049] S1: Detect the bearing temperature when the rolling mill is working normally, record it as the bearing initial temperature T0 and import it into the storage unit, and import the parameter set P into the storage unit;

E For comparison, when the external wall temperature difference ΔT ∈ the standard range of external wall temperature difference ΔT E If the condition is met, proceed to S3; otherwise, the execution unit will stop the mill driver operation.
