Drive shaft monitoring system with coded discs and light sensors
A newly granted patent (Publication Number: US11920995B2) discloses a drive shaft monitoring system designed to monitor twist or torque in a drive shaft. The system comprises multiple coded discs with slots or recesses arranged on the exterior surface of the drive shaft at different positions. These coded discs are equipped with light sensor assemblies that allow light to pass through the slots or recesses, enabling accurate monitoring of the drive shaft's behavior. The system includes independent light sensor assemblies positioned at specific circumferential distances on the coded discs, ensuring precise alignment for effective monitoring.
Furthermore, the drive shaft monitoring system incorporates a support structure that attaches the light sensor assemblies to the object structure the drive shaft is connected to, without direct contact with the coded discs or the drive shaft. This innovative system also includes a processing unit with software capabilities for calculating various parameters such as revolutions per minute, shaft torsional angle, torque, power, misalignment, and eccentricity. Additionally, the system can utilize a high-resolution incremental encoder for calibration purposes and can be combined with a flywheel sensor for measuring clutch slip. Overall, this patented drive shaft monitoring system offers a comprehensive solution for accurately monitoring and analyzing the behavior of drive shafts, ensuring optimal performance and maintenance.
