US Patent 12085131 System and method for determining degradation of rotating coupling using rotation sensors

A system and method utilize a first rotation sensor that provides a first signal indicative of a first rotation of a first end of a rotating coupling. The rotating coupling has an articulating member mechanically coupling the first end to a second end. A second rotation sensor provides a second signal indicative of a second rotation of the second end of the rotating coupling. A processor is coupled to the first and second rotation sensors and is operable to determine a relationship between the first and second rotations based on the first and second signals. Based on the relationship, the processor estimates at least one of a degradation of and a remaining useful life of the rotating coupling.
