Abstract
A system for predictive modeling of wear or damage to a driven gear of an open gear set is provided. A method of developing a predictive model of wear or damage to a driven gear of an open gear set is also provided. The system and method allow for autonomous, non-interfering dynamic collection of data that are used to assist in developing maintenance schedules for large open gear sets. More specifically, it is directed to utilizing data from monitored pinion gears of girth gear sets under full load operating conditions to predict health of a girth gear in the girth gear set.
Claims22
A system for cleaning and developing a preventative maintenance schedule using a predictive model of wear and damage to an open gear set of a rock crushing mill, which comprises a driven gear and a driver gear, the system comprising:
- an eddy current array probe, which is configured to generate and transmit scans of teeth of one gear of the open gear set;
- a non-interfering dynamic inspecting system which includes at least one non-interfering dynamic imager which is positioned and configured to generate and transmit digital images of another gear of the open gear set;
- a computing device which is electronic communication with the eddy current array probe and the non-interfering dynamic imager, and which includes a memory and a processor, the processor under control of the memory, wherein the memory is configured to receive the scans from the eddy current array probe and receive the digital images from the non-interfering dynamic imager, determine changes in both the scans and the digital images over time, statistically analyze the changes in relation to time to provide a set of time-based features, apply the time-based features as input values to a selected transformation, develop a predictive model of health and remaining useful life of the open gear set using the selected transformation and develop a preventative maintenance schedule involving cleaning the open gear set based on the predictive model;
- a sensor which is configured to sense the passage of a slurry or rock from the open gear set;
- and a reciprocating washer, which includes a nozzle mounted on a cart which is slidably, reciprocally mounted on a rail and which is in electronic communication with the processor, the reciprocating washer for cleaning the open gear set based on the predictive model.
A system for cleaning and developing a preventative maintenance schedule using predictive modeling of wear and damage to a driven gear of an open gear set of a rock crushing mill, the system comprising:
- a non-interfering dynamic inspecting system which includes at least one non-interfering dynamic imager which is positioned and configured to generate and transmit digital images of a driver gear of the open gear set;
- a computing device which is electronic communication with the non-interfering dynamic imager, and which includes a memory and a processor, the processor under control of the memory, wherein the memory retains a predictive model of health and remaining useful life of the driven gear and is configured to receive the digital images of the driver gear, determine changes in the digital images over time, statistically analyze the changes in relation to the predictive model of health and remaining useful life of the driven gear, and develop a preventative maintenance schedule;
- a sensor which is configured to sense the passage of a slurry or rock from the open gear set;
- and a reciprocating washer, which includes a nozzle mounted on a carriage which is slidably, reciprocally mounted on a rail and is and which is in electronic communication with the processor, the reciprocating washer for cleaning the open gear set based on the predictive model.
A method of developing a preventative maintenance schedule using a predictive model of wear and damage to an open gear set of a rock crushing mill, which comprises a driven gear and a driver gear, and cleaning the open gear set, the method comprising:
- selecting a system comprising a non-interfering dynamic inspecting system which includes at least one non-interfering dynamic imager, a computing device which is electronic communication with the non-interfering dynamic imager, and which includes a memory and a processor, the processor under control of the memory;
- a sensor which is configured to sense the passage of a slurry or rock from the open gear set;
- and a reciprocating washer, which includes a nozzle mounted on a carriage which is slidably, reciprocally mounted on a rail and which is in electronic communication with the processor, the non-interfering dynamic imager generating and transmitting digital images of teeth of a gear of the open gear set to the computer;
- the computer analyzing, compiling and storing the digital images and the scans as a data set;
- the computer determining changes in the data set over time, statistically analyzing the changes in relation to time to provide a set of time-based features, applying the time-based features as input values to a selected transformation, developing a predictive model of health and remaining useful life of the open gear set using the selected transformation, and developing a preventative maintenance schedule, the sensor sensing the passage of a slurry or crushed rock from the open gear set and cleaning the open gear set with the reciprocating washer based on the predictive model.
