Means for measuring angular displacement of coaxially rotating elements
Abstract
Abstract THIS TORQUE METER HAS TWO DISKS DISPOSED SIDE BY SIDE AND FIXED TO AXIALLY SPACED POINTS ON A SHAFT, MAGNETIC RECORDINGS OF ONE CONFIGURATION EXTENDING AROUND THE PERIPHERY OF ONE DISK AND MAGNETIC RECORDINGS OF ANOTHER CONFIGURATION EXTENDING AROUND THE PERIPHERY OF THE OTHER DISK. IT ALSO HAS A SINGLE MAGNETIC HEAD DISPOSED TO SENSE THE MAGNETIC FLUX FROM THE RECORDINGS ON BOTH ROTATING DISKS TO PRODUCE TWO DISTINCT SIGNALS APPEARING ALTERNATELY WITH TIME. THE SIGNALS FROM THE MAGNETIC HEAD ARE FED TO A CIRCUIT THAT RESPONDS TO BOTH SIGNALS TO PRODUCE A RECTANGULAR WAVE WHEREIN THE DIFFERENCE BETWEEN ADJACENT HALF CYCLES IS RELATED TO THE RELATIVE ROTARY MOVEMENT OF THE DISKS.
