Embodiment 1

[0063] refer to diagram 2-1 , shows the structural block diagram of the first embodiment of the online oil monitoring system of the high-power reducer of the present invention, including the oil inlet pipe 21, the oil return pipe 22, the oil pump 23, the motor 24, the data acquisition unit 25, the data analysis unit 26 and the control unit 20, of which:

[0064] One end of the oil inlet pipe 21 and the oil return pipe 22 are both connected to the lower box oil pool of the high-power reducer;

[0065] The other end of the oil inlet pipe 21 is connected with the oil pump 23;

[0066] The other end of the oil return pipe 22 is connected to the data acquisition unit 25;

[0067] Oil pump 23 is driven by motor 24;

[0068] Under the control of the control unit 20, the motor 24 drives the oil pump 23 to pump oil from the lower box oil pool of the high-power speed reducer;

[0069] The oil enters the data acquisition unit 25 through the oil inlet pipe 21, and then returns to the...

Embodiment 2

[0079] refer to Figure 2-2 , shows the structural block diagram of the second embodiment of the online oil monitoring system for high-power reducers of the present invention, except for the oil inlet pipe 21, the oil return pipe 22, the oil pump 23, the motor 24, and the data acquisition unit 25 included in the first embodiment of the system In addition to functional units such as data analysis unit 26 and control unit 20, it also includes a network 29 required for data transmission, a host computer 27 required for data analysis, and an oil analysis center server 28, which can collect relevant working condition parameters for each sensor. Further analysis (such as the size and concentration of abrasive particles, the viscosity of lubricating oil, etc.) can not only obtain more accurate analysis results, but also can analyze the wear of high-power reducers according to the changes in parameters collected continuously or periodically. Prediction and analysis of the situation ca...

Abstract

The invention provides an on-line oil monitoring method and an on-line oil monitoring system for a high-power speed reducer. The method comprises the following steps of: acquiring working condition parameters of oil of the high-power speed reducer in real time or according to a preset period; comparing the working condition parameters with preset parameter threshold values; and if the working condition parameters are greater than the preset parameter threshold values, sounding an alarm. According to the method and the system, the working condition parameters of the oil of the high-power speed reducer are dynamically acquired and compared and analyzed, so that the high-power speed reducer can be monitored on line; when the working condition of the speed reducer is worse, the system can timely sound the alarm; and therefore, the problem that the abrasion condition of the speed reducer cannot be monitored in real time and accurately judged in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment wear state monitoring, in particular to an online oil monitoring method and system for a high-power reducer. Background technique [0002] High-power reducers are key transmission components for efficient mining, reloading, crushing, and transporting equipment in road construction, mining and other industries. During the working process, the transmission gears not only bear heavy loads, but also random and alternating loads such as shocks and vibrations. , Tooth surface wear due to poor lubrication is one of the main failure forms of gear transmission, and it is also one of the main causes of broken teeth. Therefore, in order to ensure the normal operation of high-power reducers, it is necessary to monitor the wear of the reducer oil in time Whether the parameters affecting the lubrication effect such as particle size, abrasive concentration, working temperature, viscosity, and water ...
