As shown in fig. 1, the embodiment of the present disclosure provides a power head speed reducer 100, including:
the sensing module 110 is arranged on the shell of the power head speed reducer and is used for acquiring temperature data of lubricating liquid in the power head speed reducer and liquid level height data of the lubricating liquid;
the controller 120 is electrically connected with the signal output end of the sensing module 110, and is used for determining a temperature result corresponding to the temperature data and determining a liquid level height result corresponding to the liquid level height data;
and the display screen 130 is electrically connected with the signal output end of the controller and is used for displaying the temperature result and the liquid level height result.
In this disclosed embodiment, through set up the sensing module in the inside casing of unit head speed reducer to can detect the inside operating mode data of unit head speed reducer, and then show the inside temperature result and the liquid level height result of lubrication liquid of unit head speed reducer through the display screen, so that operating personnel knows inside operating mode under the circumstances of avoiding dismantling the unit head speed reducer, improve the preliminary efficiency and the reliability of judging of trouble.
The number of the power head speed reducers 100 is not limited by the power head, the number of the speed reducers is determined by the output torque of the host, the number of the power head speed reducers can be 1 or more, and the working principles of the power head speed reducers with different numbers are the same.
As shown in fig. 2 and 3, the sensor module 110 may be one sensor or a plurality of sensors, which is not limited herein. Taking a plurality of sensors as an example, a temperature sensor for detecting temperature data of the lubricating liquid and a liquid level sensor for detecting liquid level height data of the lubricating liquid may be included. The plurality of sensors may be integrated or distributed, and are not limited herein.
The controller 120 is electrically connected to the signal output end of the sensor module 110, and obtains temperature data and liquid level height data collected by the sensor module 110, so as to calculate the temperature result of the lubricating liquid according to the obtained temperature data, and calculate the liquid level height result of the lubricating liquid according to the obtained liquid level height data.
Specifically, the sensing module 110 may collect temperature data of the lubricating fluid in real time, and the controller 120 obtains the temperature data for a period of time and then calculates a temperature average value in the period of time as a temperature result.
The input shaft rotates to drive the planetary gear train to rotate in the housing of the power head speed reducer 100, and centrifugal force caused by rotation of the planetary gear train agitates the lubricating liquid, so that the liquid level of the lubricating liquid is changed. Similarly, the sensing module 110 may collect the liquid level data of the lubricating liquid in real time, and the controller 120 may calculate the average value of the liquid level in a period of time as the liquid level result after obtaining the liquid level data of the period of time.
Of course, the calculation of the temperature result and the liquid level result is only an example and is not limited to the above-mentioned example calculation method; the temperature data with the highest repetition frequency can be used as a temperature result, and the liquid level height data with the highest repetition frequency can be used as a liquid level height result; other calculation methods are also possible and are not limited herein.
The display 130 is electrically connected to the signal output end of the controller 120, so as to obtain the temperature result and the liquid level height result of the lubricating liquid, and further display the results.
The display 130 may be an LED (light-emitting diode) display, a liquid crystal display (Liquid Crystal Display, LCD), or other displays, which are not limited herein.
Further, as shown in fig. 3, a buoy 140 is disposed in the lubricating fluid; the sensor module 110 detects the height data of the float 140 to determine the level height data of the lubricating fluid.
The float 140 floats on the surface of the lubricating fluid and the height data of the float is related to the height data of the surface of the lubricating fluid. In this embodiment, the sensor module 110 determines the height data of the surface of the lubricating fluid by collecting the height data of the buoy.
Further, the controller 120 outputs a liquid level normal signal when the liquid level height result is greater than a first height value and less than a second height value;
the controller 120 outputs a liquid level abnormality signal when the liquid level height result is smaller than the first height value or the liquid level height result is larger than the second height value;
the first height value is less than the second height value.
If the result of the level height of the lubricating fluid is between the first height value (L) and the second height value (H), the level value of the lubricating fluid is within a normal range. The lubricating liquid can form an oil film on the surface of the part, the oil film can prevent the part from being directly contacted with water and acid gas, rust or corrosion can be prevented, and meanwhile, the lubricating liquid has the functions of cleaning impurities, cooling, corrosion prevention, rust prevention and the like on the power head speed reducer.
If the liquid level of the lubricating fluid is lower than the first height value (L), the lubricating fluid in the power head speed reducer 100 is too small. Too little lubricating liquid can lead to lubrication failure, easily leads to too low lubricating liquid pressure of the power head speed reducer, can not meet due lubricating requirements, and even serious, can also cause damage of more parts, such as a shaft gear shaft, a bearing, a planet carrier and the like. In this case, it is necessary to supplement the lubricating fluid into the power head reduction gear 100.
If the result of the liquid level of the lubricating fluid is higher than the second height value (H), the lubricating fluid in the power head speed reducer 100 is excessive. Excessive lubrication can cause the planet gear system to become more resistant when rotating at high speed. Meanwhile, once air or lubricating liquid discharged through the flow guide pipe is not smooth in circulation, the air pressure value in the shell exceeds an allowable value, the lubricating liquid is triggered to break the sealing element of the power head speed reducer, and oil leakage of the power head speed reducer is caused.
Further, the controller 120 outputs a temperature normal signal when the temperature result is equal to or less than a safe temperature value;
the controller 120 outputs a temperature abnormality signal when the temperature result is greater than a safe temperature value.
Under the condition of excessive lubricating fluid, resistance becomes larger when the planetary gear train rotates at a high speed, so that the heating capacity of the power head speed reducer 100 becomes larger, the bearing is caused to have high temperature, and the temperature of the lubricating fluid is further increased. When the temperature result calculated by the controller 120 based on the collected temperature data is greater than the safe temperature value, it is considered that the internal failure of the power head speed reducer 100 causes the temperature of the lubricating fluid to be too high, thereby outputting a temperature abnormality signal.
The safe temperature value may be any temperature of 80 to 110 ℃, and is not limited herein.
Further, the display 130 sends out an alarm signal when receiving the liquid level abnormality signal and/or the temperature abnormality signal.
When the display 130 receives the temperature anomaly signal, the alarm signal may be an anomaly display for the temperature result. For example: when a temperature normal signal is received, a display screen displays a temperature result by adopting a green picture; and when the temperature abnormal signal is received, the display screen displays a temperature result by adopting a red picture.
When the display screen 130 receives the liquid level abnormality signal, the alarm signal may be an abnormal display for the liquid level height result. For example: when a liquid level normal signal is received, a display screen displays a liquid level height result by adopting a green picture; when the liquid level abnormal signal is received, the display screen displays the liquid level height result by adopting a red picture.
In addition, the alarm signal may also include a flashing display screen, and the mode of making an alarm sound or an alarm voice by using a speaker of the display screen is not limited herein.

step 430: and outputting the temperature result and the liquid level height result so that a display screen displays the temperature result and the liquid level height result.
In this disclosed embodiment, through set up the sensing module in the inside casing of unit head speed reducer to can detect the inside operating mode data of unit head speed reducer, and then show the inside temperature result and the liquid level height result of lubrication liquid of unit head speed reducer through the display screen, so that operating personnel knows inside operating mode under the circumstances of avoiding dismantling the unit head speed reducer, improve the preliminary efficiency and the reliability of judging of trouble.
The number of the power head speed reducers is not limited by the power head, the number of the speed reducers is determined by the output torque of the host, the number of the power head speed reducers can be 1 or more, and the working principles of the power head speed reducers with different numbers are the same.
As shown in fig. 2 and 3, the sensor module may be one sensor or a plurality of sensors, which is not limited herein. Taking a plurality of sensors as an example, a temperature sensor for detecting temperature data of the lubricating liquid and a liquid level sensor for detecting liquid level height data of the lubricating liquid may be included. The plurality of sensors may be integrated or distributed, and are not limited herein.
The controller is electrically connected with the signal output end of the sensing module to acquire temperature data and liquid level height data acquired by the sensing module, so that a temperature result of the lubricating liquid is calculated through the acquired temperature data, and a liquid level height result of the lubricating liquid is calculated through the acquired liquid level height data.
Specifically, the sensing module may collect temperature data of the lubricating liquid in real time, and the controller obtains the temperature data for a period of time and then calculates a temperature average value in the period of time as a temperature result.
The input shaft rotates to drive the planetary gear train to rotate in the shell of the power head speed reducer, and centrifugal force caused by rotation of the planetary gear train agitates the lubricating liquid, so that the liquid level of the lubricating liquid is changed. Similarly, the sensing module can collect liquid level height data of the lubricating liquid in real time, and after the controller obtains the liquid level height data for a period of time, the average value of the liquid level heights in the period of time is calculated and obtained to be used as a liquid level height result.
Of course, the calculation of the temperature result and the liquid level result is only an example and is not limited to the above-mentioned example calculation method; the temperature data with the highest repetition frequency can be used as a temperature result, and the liquid level height data with the highest repetition frequency can be used as a liquid level height result; other calculation methods are also possible and are not limited herein.
The display screen is electrically connected with the signal output end of the controller, so that the temperature result and the liquid level height result of the lubricating liquid can be obtained, and further display can be performed.
The display screen may be an LED (light-emitting diode) display screen, a liquid crystal display screen (Liquid Crystal Display, LCD), or other display screens, which is not limited herein.
Further, the obtaining the liquid level height data of the lubricating liquid in the power head speed reducer includes:
acquiring height data of a lubricating liquid buoy in the power head speed reducer;
and determining liquid level height data of the lubricating liquid corresponding to the height data of the buoy.
A buoy is arranged in the lubricating liquid; the sensing module detects the height data of the buoy to determine the liquid level height data of the lubricating liquid.
The buoy floats on the surface of the lubricating fluid, and the height data of the buoy is related to the height data of the surface of the lubricating fluid. In this embodiment, the sensing module determines the height data of the surface of the lubricating fluid by collecting the height data of the buoy.
Further, the method further comprises:
outputting a liquid level normal signal when the liquid level height result is larger than the first height value and smaller than the second height value; or,
and outputting a liquid level abnormal signal to enable the display screen to send out an alarm signal when the liquid level height result is smaller than the first height value or the liquid level height result is larger than the second height value.
If the result of the level height of the lubricating fluid is between the first height value (L) and the second height value (H), the level value of the lubricating fluid is within a normal range. The lubricating liquid can form an oil film on the surface of the part, the oil film can prevent the part from being directly contacted with water and acid gas, rust or corrosion can be prevented, and meanwhile, the lubricating liquid has the functions of cleaning impurities, cooling, corrosion prevention, rust prevention and the like on the power head speed reducer.
If the result of the liquid level of the lubricating liquid is lower than the first height value (L), the lubricating liquid in the power head speed reducer is too little. Too little lubricating liquid can lead to lubrication failure, easily leads to too low lubricating liquid pressure of the power head speed reducer, can not meet due lubricating requirements, and even serious, can also cause damage of more parts, such as a shaft gear shaft, a bearing, a planet carrier and the like. Under such a situation, it is necessary to supplement the lubrication fluid into the power head speed reducer.
If the result of the liquid level of the lubricating liquid is higher than the second height value (H), the lubricating liquid in the power head speed reducer is excessive. Excessive lubrication can cause the planet gear system to become more resistant when rotating at high speed. Meanwhile, once air or lubricating liquid discharged through the flow guide pipe is not smooth in circulation, the air pressure value in the shell exceeds an allowable value, the lubricating liquid is triggered to break the sealing element of the power head speed reducer, and oil leakage of the power head speed reducer is caused.
Further, the method further comprises:
outputting a temperature normal signal when the temperature result is smaller than or equal to a safe temperature value;
and when the temperature result is greater than the safety temperature value, outputting a temperature abnormality signal to enable the display screen to send out an alarm signal.
Under the condition of excessive lubricating fluid, resistance can become larger when the planetary gear train rotates at a high speed, so that the heating capacity of the power head speed reducer becomes larger, the bearing is caused to have high temperature, and the temperature of the lubricating fluid is further increased. When the temperature result obtained by the controller based on the collected temperature data is larger than the safety temperature value, the temperature of the lubricating liquid is considered to be too high due to the fact that the inside of the power head speed reducer fails, and accordingly a temperature abnormality signal is output.
The safe temperature value may be any temperature of 80 to 110 ℃, and is not limited herein.
When the display screen receives the temperature abnormality signal, the alarm signal can be an abnormality display aiming at the temperature result. For example: when a temperature normal signal is received, a display screen displays a temperature result by adopting a green picture; and when the temperature abnormal signal is received, the display screen displays a temperature result by adopting a red picture.
When the display screen receives the liquid level abnormal signal, the alarm signal can be abnormal display aiming at the liquid level height result. For example: when a liquid level normal signal is received, a display screen displays a liquid level height result by adopting a green picture; when the liquid level abnormal signal is received, the display screen displays the liquid level height result by adopting a red picture.
