As shown in fig. 1, an embodiment of the present disclosure provides a power head reducer 100, including:

the sensing module 110 is arranged on a shell of the power head speed reducer and is used for acquiring temperature data and liquid level height data of lubricating liquid in the power head speed reducer;

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 the embodiment of the disclosure, through the inside sensing module that sets up of casing of unit head speed reducer to can detect the inside operating mode data of unit head speed reducer, and then show the temperature result and the liquid level height result of the inside lubricated liquid of unit head speed reducer through the display screen, so that operating personnel knows inside operating mode under the condition of being in need of dismantling the unit head speed reducer, improve the efficiency and the reliability that the trouble was tentatively judged.

The number of the power head reducers 100 is not limited by the power heads, the number of the reducers is determined by the output torque of the host, the number of the power head reducers can be 1 or more, and the working principles of the power head reducers with different numbers are the same.

As shown in fig. 2 and fig. 3, the sensing module 110 may be a single sensor or a plurality of sensors, which is not limited herein. Taking the 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 disposed integrally or dispersedly, and is not limited herein.

The controller 120 is electrically connected with the signal output end of the sensing module 110, and acquires the temperature data and the liquid level height data acquired by the sensing module 110, so that the temperature result of the lubricating liquid is calculated through the acquired temperature data, and the liquid level height result of the lubricating liquid is calculated through the acquired liquid level height data.

Specifically, the sensing module 110 may collect temperature data of the lubricating liquid in real time, and the controller 120 calculates an average temperature value in a period of time after obtaining the temperature data of 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 reducer 100, and centrifugal force caused by rotation of the planetary gear train stirs lubricating liquid, so that the liquid level of the lubricating liquid changes. Similarly, the liquid level height data of the lubricating liquid can be collected by the sensing module 110 in real time, and after the controller 120 acquires the liquid level height data of a period of time, the average value of the liquid level heights in the period of time is calculated and obtained as the liquid level height result.

Of course, the calculation of the temperature result and the liquid level height result is only an example and is not limited to the above-mentioned calculation method; or the temperature data with the most repetition frequency can be used as the temperature result, and the liquid level height data with the most repetition frequency can be used as the liquid level height result; other calculation methods are also possible, and are not limited herein.

The display screen 130 is electrically connected to the signal output terminal 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 temperature result and the liquid level height result.

The Display 130 may be a light-emitting diode (LED) Display, a Liquid Crystal Display (LCD), or other displays, and is not limited herein.

Further, as shown in fig. 3, a float 140 is provided in the lubricating fluid; the sensing module 110 senses 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 sensing module 110 determines the height data of the surface of the lubricating fluid by collecting the height data of the float.

Further, the controller 120 outputs a normal liquid level signal when the liquid level height result is greater than the first height value and less than the second height value;

the controller 120 outputs a liquid level abnormal 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 level height result of the lubricating liquid is between the first height value (L) and the second height value (H), the level value of the lubricating liquid is within a normal range. The lubricating liquid can form an oil film on the surface of the part, the oil film can avoid the direct contact of the part with water and acid gas, can prevent the corrosion or corrosion, and has the functions of cleaning impurities, cooling, corrosion prevention, rust prevention and the like on the power head speed reducer.

If the liquid level height result of the lubricating liquid is lower than the first height value (L), the lubricating liquid in the power head reducer 100 is too little. The lubricating fluid is too little, which can cause poor lubrication, easily causes the pressure of the lubricating fluid of the power head speed reducer to be too low, and the lubricating fluid cannot meet the due lubricating requirement, and even seriously can cause the damage of more parts, such as a shaft gear shaft, a bearing, a planet carrier and the like. In this situation, lubricating fluid needs to be added into the power head reducer 100.

If the liquid level height result of the lubricating liquid is higher than the second height value (H), the lubricating liquid in the power head speed reducer 100 is excessive. Too much lubricant will cause the resistance to become greater when the planetary gear train rotates at high speed. Meanwhile, once the air or the lubricating liquid exhausted through the guide pipe is not smooth to circulate, the air pressure value in the shell body exceeds an allowable value, the lubricating liquid is caused to break a sealing piece of the power head speed reducer, and the oil leakage of the power head speed reducer is caused.

Further, the controller 120 outputs a temperature normal signal when the temperature result is less than or equal to a safe temperature value;

the controller 120 outputs a temperature abnormality signal when the temperature result is greater than a safe temperature value.

When the amount of the lubricating fluid is too large, the resistance of the planetary gear train at high-speed rotation becomes larger, so that the heat generation of the power head reducer 100 becomes large, the bearing is heated to a high temperature, and the temperature of the lubricating fluid rises. When the controller 120 calculates based on the acquired temperature data that the temperature result is greater than the safe temperature value, it is considered that the temperature of the lubricating fluid is too high due to a fault occurring inside the power head speed reducer 100, and thus a temperature abnormality signal is output.

The safe temperature value can be any one of 80-110 ℃, and is not limited herein.

Further, the display screen 130 sends an alarm signal when receiving the liquid level abnormal signal and/or the temperature abnormal signal.

When the display screen 130 receives the temperature abnormality signal, the alarm signal may be an abnormality display for the temperature result. For example: when a normal temperature signal is received, the 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 a liquid level anomaly signal, the warning signal may be an anomaly display for the liquid level height result. For example: when a normal liquid level signal is received, the display screen displays a liquid level height result by adopting a green picture; and 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 picture, and an alarm sound or an alarm voice is emitted by using a speaker of the display screen, which is not limited herein.

The embodiment of the present disclosure further provides a control method of a power head speed reducer, as shown in fig. 4, the method includes:

step 410: acquiring temperature data of lubricating liquid in the power head speed reducer and liquid level height data of the lubricating liquid;

step 420: determining a temperature result corresponding to the temperature data and determining a liquid level height result corresponding to the liquid level height data;

step 430: and outputting the temperature result and the liquid level height result so as to enable a display screen to display the temperature result and the liquid level height result.

In the embodiment of the disclosure, through the inside sensing module that sets up of casing of unit head speed reducer to can detect the inside operating mode data of unit head speed reducer, and then show the temperature result and the liquid level height result of the inside lubricated liquid of unit head speed reducer through the display screen, so that operating personnel knows inside operating mode under the condition of being in need of dismantling the unit head speed reducer, improve the efficiency and the reliability that the trouble was tentatively judged.

The number of the power head speed reducers is not limited by the power heads, 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 fig. 3, the sensing module may be a single sensor or a plurality of sensors, which is not limited herein. Taking the 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 disposed integrally or dispersedly, and is not limited herein.

The controller is electrically connected with a signal output end of the sensing module, and acquires 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 sensor module may collect temperature data of the lubricating liquid in real time, and after the controller obtains the temperature data of a period of time, the controller calculates to obtain an average temperature 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 reducer, and centrifugal force caused by rotation of the planetary gear train stirs lubricating liquid to change the liquid level height of the lubricating liquid. Similarly, the liquid level height data of the lubricating liquid can be collected by the sensing module in real time, and after the controller acquires the liquid level height data of a period of time, the average value of the liquid level height in the period of time is calculated and obtained as the liquid level height result.

Of course, the calculation of the temperature result and the liquid level height result is only an example and is not limited to the above-mentioned calculation method; or the temperature data with the most repetition frequency can be used as the temperature result, and the liquid level height data with the most repetition frequency can be used as the 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 the display is further performed.

The Display screen may be a light-emitting diode (LED) Display screen, a Liquid Crystal Display (LCD), or other Display screens, and is not limited herein.

Further, the acquiring liquid level height data of lubricating liquid in the power head speed reducer includes:

acquiring height data of a lubricating liquid buoy in the power head speed reducer;

determining level height data of the lubricating fluid corresponding to the height data of the float.

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 liquid, and the height data of the buoy is related to the height data of the surface of the lubricating liquid. In this embodiment, the sensing module determines the height data of the surface of the lubricating fluid by collecting the height data of the float.

Further, the method further comprises:

when the liquid level height result is larger than the first height value and smaller than the second height value, outputting a liquid level normal signal; alternatively, the first and second electrodes may be,

and 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, outputting a liquid level abnormal signal to enable the display screen to send an alarm signal.

If the level height result of the lubricating liquid is between the first height value (L) and the second height value (H), the level value of the lubricating liquid is within a normal range. The lubricating liquid can form an oil film on the surface of the part, the oil film can avoid the direct contact of the part with water and acid gas, can prevent the corrosion or corrosion, and has the functions of cleaning impurities, cooling, corrosion prevention, rust prevention and the like on the power head speed reducer.

If the liquid level height result of the lubricating liquid is lower than the first height value (L), the lubricating liquid in the power head speed reducer is too little. The lubricating fluid is too little, which can cause poor lubrication, easily causes the pressure of the lubricating fluid of the power head speed reducer to be too low, and the lubricating fluid cannot meet the due lubricating requirement, and even seriously can cause the damage of more parts, such as a shaft gear shaft, a bearing, a planet carrier and the like. Under the condition, lubricating liquid needs to be added into the power head speed reducer.

If the liquid level height result of the lubricating liquid is higher than the second height value (H), the lubricating liquid in the power head speed reducer is excessive. Too much lubricant will cause the resistance to become greater when the planetary gear train rotates at high speed. Meanwhile, once the air or the lubricating liquid exhausted through the guide pipe is not smooth to circulate, the air pressure value in the shell body exceeds an allowable value, the lubricating liquid is caused to break a sealing piece of the power head speed reducer, and the oil leakage of the power head speed reducer is caused.

Further, the method further comprises:

when the temperature result is less than or equal to the safe temperature value, outputting a normal temperature signal;

and when the temperature result is greater than the safe temperature value, outputting a temperature abnormal signal to enable the display screen to send an alarm signal.

Under the condition that the lubricating liquid is excessive, the resistance can become bigger when the planetary gear train rotates at a high speed, so that the heating value of the power head reducer is increased, the bearing is high in temperature, and the temperature of the lubricating liquid is increased. When the controller calculates and obtains a temperature result based on the acquired temperature data, the temperature result is larger than the safe temperature value, the fact that the temperature of the lubricating liquid is too high due to the fact that a fault occurs inside the power head speed reducer is considered, and therefore a temperature abnormal signal is output.

The safe temperature value can be any one of 80-110 ℃, and is not limited herein.

When the display screen receives the temperature abnormal signal, the alarm signal can be abnormal display aiming at the temperature result. For example: when a normal temperature signal is received, the 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 normal liquid level signal is received, the display screen displays a liquid level height result by adopting a green picture; and 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 picture, and an alarm sound or an alarm voice is emitted by using a speaker of the display screen, which is not limited herein.

The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the invention pertains, several simple deductions and substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
