Gyro Sensor Track Wrap Monitoring for Undercarriage Wear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wear monitoring systems for track assemblies in mobile machines are prone to maintenance issues due to the use of multiple sensors, making them less robust and potentially inaccurate in determining the need for maintenance, which can negatively affect operational profitability.
Innovation Solution
A wear monitoring system that includes a track wrap angle sensor, such as a gyro sensor, attached to track components like idlers and track pins, which detects changes in the track wrap angle to determine wear and alert operators when maintenance is necessary, thereby reducing the need for multiple sensors and improving accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors are used in the wear monitoring system, then the measurement accuracy may be improved, but the system reliability deteriorates due to increased maintenance requirements
Solution Approach 1:
The patent combines multiple sensing functions into a single gyro sensor that measures both the angle and rate of change of the track wrap angle. This consolidation reduces the number of components from multiple sensors to one, thereby improving system reliability while maintaining measurement precision through the sensor's dual measurement capability.
2Loss of information
If multiple sensors are deployed, then more comprehensive wear data can be collected, but the device complexity increases
Solution Approach 1:
The gyro sensor is designed to perform multiple functions: measuring the track wrap angle, measuring the rate of change of the wrap angle, and providing data for wear calculations. This multi-functionality eliminates the need for separate sensors for different measurements, reducing device complexity while ensuring comprehensive wear data collection.
3Ease of operation
If periodic maintenance is performed based on time intervals, then the operation is simple, but the productivity decreases due to premature or delayed maintenance
Solution Approach 1:
The system implements continuous feedback by monitoring the track wrap angle and its rate of change in real-time. This feedback mechanism provides actual wear condition data that triggers maintenance only when necessary, replacing simple time-based scheduling with condition-based maintenance. This approach maintains operational simplicity while maximizing productivity by avoiding premature maintenance and preventing costly breakdowns.
