Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.
It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.
In a lubricating oil monitoring mode in the prior art, a steel deep ruler is inserted into a gear box, and after the steel ruler is pulled out, the oil level of the gear box is judged by checking the immersion degree through scales on the steel ruler. The subsequent oil level of the gearbox adopts a liquid level measuring method capable of being directly observed, namely, one or two transparent glass plates are arranged on the side surface of the box body, scales are added, and manual reading is adopted. This approach also has the following disadvantages: parking inspection is required, and operation is inconvenient; manual reading, the glass is easy to be stained with oil, and the reading is inaccurate; passive detection, failing to actively improve lubrication deficiency; the lubricating oil can not be heated, so that the temperature of the lubricating oil is ensured; the gearbox oil condition cannot be monitored in real time.
In another lubricating oil monitoring mode in the prior art, various types of liquid level sensors such as a floater and a capacitor are added in a box body to monitor the liquid level in the box body in real time, and an alarm function is realized when the liquid level is lower than a preset value. This approach has the following disadvantages: in the running process of the locomotive, oil in the gear box is taken away by the gear, the liquid level is reduced, and the real-time monitoring liquid level data is invalid; passive detection, which cannot actively improve lubrication deficiency; the lubricating oil can not be heated, and good lubricating conditions are ensured; the state of the lubricating oil cannot be monitored in real time.
The invention provides a brand-new gear box lubricating oil monitoring and control integrated system which can realize real-time monitoring of the lubricating oil liquid level of a gear box, and realize active oil injection lubrication by monitoring the temperature in the gear box aiming at the condition that the gear and a bearing are damaged due to low rotating speed, large load and insufficient splash lubrication of the gear under the working conditions of starting and climbing of a locomotive and the condition that the lubrication of the gear and the bearing is difficult to ensure.
Referring to fig. 1, the invention provides a method for monitoring lubricating oil of a gearbox, which comprises the following steps:
step S1, obtaining a vehicle speed detection value;
s2, when the speed detection value is larger than 0 and smaller than a speed preset value, acquiring an oil level detection value, an environment temperature and a gear box temperature detection value of gear box lubricating oil;
and S3, when the oil level detection value is larger than a first oil level preset value and the difference value between the temperature detection value and the ambient temperature is larger than a first temperature preset value, controlling the splashing device to work, so that lubricating oil is splashed at the meshing position of the splashing device and the gear.
According to the method and the system for monitoring the lubricating oil of the gear box, disclosed by the embodiment of the invention, when the vehicle speed is lower (smaller than a preset speed value), the oil level detection value, the ambient temperature and the temperature detection value of the gear box are obtained, when the difference value between the temperature detection value and the ambient temperature is larger than a first preset temperature value, the fact that the temperature of the gear box is increased due to insufficient lubrication of the gear is indicated, and when the oil level detection value is larger than the first preset oil level value, the fact that the storage capacity of the lubricating oil is large at the moment is indicated, the lubricating oil is suitable for splashing, so that the splashing device is controlled to work at the moment, the splashing device splashes the lubricating oil at the meshing part of the gear to assist in lubricating the splashed lubricating oil at the meshing part of the gear, and the good lubricating state of the gear is favorably ensured.
A vehicle is generally provided with a vehicle speed sensor and an ambient temperature sensor from which a vehicle speed detection value and an ambient temperature can be acquired, respectively. An oil level sensor and a temperature sensor can be additionally arranged in the gear box to detect the oil level of lubricating oil and the temperature of the gear box, and the temperature sensor can be arranged close to an oil storage cavity of the gear box, so that the temperature detected by the temperature sensor is close to the temperature of the lubricating oil. In some embodiments, the speed preset value is 50 km/h, the first oil level preset value is 55mm, and the first temperature preset value is 50 ℃. Of course, in other embodiments, the corresponding speed preset value, first oil level preset value, and first temperature preset value may also be set according to actual conditions (e.g., vehicle type, lubricating oil type).
The splash device is configured to draw lubricant from the reservoir of the gearbox and direct the lubricant toward the gear mesh of the gearbox for splashing. In some embodiments, the sputtering apparatus comprises: oil pump, pipeline, shower nozzle, wherein the spout of shower nozzle is towards gear engagement department, pipeline one end with the shower nozzle is connected, and the other end stretches into in the oil storage chamber of gear box, the oil pump sets up on the pipeline.
Referring to fig. 2, the method further includes: and when the oil level detection value is smaller than a second oil level preset value or the difference value between the temperature detection value and the ambient temperature is smaller than a second temperature preset value, controlling the splashing device not to work.
And when the oil level detection value is smaller than the second oil level preset value, the lubricating oil storage amount is small at the moment, the lubricating oil is difficult to be drawn out for splashing, and therefore splashing work is not performed any more. When the difference value between the temperature detection value and the ambient temperature is smaller than a second temperature preset value, the gear lubrication effect is good at the moment, and auxiliary lubrication is not needed to be carried out through splashing of lubricating oil. In an embodiment of the present invention, the second oil level preset value is smaller than the first oil level preset value with a certain difference therebetween; similarly, the second temperature preset value is less than the first temperature preset value, with a certain difference between the two. By such an arrangement, it is possible to avoid frequent turning on or off of the sputtering apparatus due to fluctuations of the detection value in the vicinity of the critical value when only one critical value is set. In some embodiments, the second oil level is preset at 35mm and the second temperature is preset at 40 ℃. Of course, in other embodiments, the corresponding second oil level preset value and second temperature preset value may also be set according to actual conditions.
The method is implemented by a gearbox lubrication oil monitoring system, the method further comprising: and when the speed detection value is larger than the speed preset value, controlling the system to stand by. When the speed detection value is larger than the speed preset value, the speed is high, the gear can timely bring lubricating oil to a gear meshing surface for lubricating under normal conditions, auxiliary lubrication is not needed, and therefore the system can be in a standby state.
The inventors have further recognized that in a low temperature environment in winter, gearbox oil is too cold, has poor flow properties, is difficult to form an oil film, and provides good lubrication. Based on such consideration, the invention also designs the following steps: and when the temperature detection value is smaller than a third temperature preset value, controlling a heating device to heat the lubricating oil of the gearbox until the temperature detection value is larger than a fourth temperature preset value. Therefore, the active heating function of the lubricating oil is realized by monitoring the temperature in the gearbox, the oil temperature is improved, the fluidity is enhanced, and the good lubricating performance is ensured. The third preset temperature value may be 0 deg.c and the fourth preset temperature value may be 10 deg.c. By setting the third temperature preset value and the fourth temperature preset value, it is possible to prevent the heating device from being frequently turned on or off due to fluctuation of the detection value in the vicinity of the critical value when only one critical value is set.
In some embodiments, the method further comprises: and when the vehicle stops, acquiring an oil level detection value of the lubricating oil of the gearbox, and when the oil level detection value is smaller than a third oil level preset value (the lowest oil level for stopping), sending an alarm signal. Thereby ensuring that enough lubricating oil can be reserved in the gear box after the vehicle is stopped. The third oil level preset value may be, for example, 65mm. In practical use, other suitable third oil level preset values may be set according to specific conditions such as the type of lubricating oil, the type of vehicle and the like. In addition, when the vehicle speed is greater than 0, the oil level is monitored but the system does not give an alarm, and the oil level is monitored after the vehicle is stopped for 30 minutes to determine whether the oil tank is short of oil or not.
In some embodiments, the method further comprises: setting a temperature control mode in which the speed detection value is not taken into consideration, and performing the steps of:
acquiring ambient temperature and gear box temperature detection values;
when the difference value between the temperature detection value and the ambient temperature is greater than the first temperature preset value, controlling the sputtering device to work;
and when the difference value between the temperature detection value and the ambient temperature is smaller than a second preset temperature value, controlling the splashing device not to work.
The inventors have realized that in some situations where the vehicle is not running at low speed, there may also be scenarios where the gear lubrication is not sufficient and auxiliary lubrication is required. In view of the above, the present invention further provides the temperature control mode in which the operation or non-operation of the splash device is controlled only based on the comparison between the temperature detection value and the preset value, without considering the magnitude of the vehicle speed. The operator can switch to the temperature control mode by pressing the corresponding button or clicking the corresponding operation key.
In some embodiments, the method further comprises: setting an oil level control mode in which the speed detection value is not taken into consideration, and performing the steps of:
when the oil level detection value is larger than the first oil level preset value, controlling the splashing device to work;
and when the oil level detection value is smaller than a second oil level preset value, controlling the splashing device not to work.
The inventors have realized that in some situations other than low vehicle speed, there may be scenarios where the gear lubrication is not sufficient and auxiliary lubrication is required. In view of such consideration, the present invention further provides the oil level control mode in which the operation or non-operation of the splash device is controlled only based on the comparison of the detected value of the oil level with a preset value, without considering the magnitude of the vehicle speed. The operator can switch to the oil level control mode by pressing the corresponding button or clicking the corresponding operation key.
