Shaft torsion and rotation angle measuring device - contains two coil arrangements with six annular coils arranged in groups for measurement on interconnected shafts

摘要

Two coil arrangements (31,32) are arranged on two shafts (26,27) in the connection region of the shafts to leave an air gap between their magnetic bodies. The magnetic bodies of the first coil arrangement are connected in a group with two annular coils, and the magnetic body of the third coil arrangement is connected to a third annular coil. The three annular coils (2,2',2'') of the first and second coil arrangements are enclosed by a fourth, fifth and sixth annular coil (7,7'',8''), which form a coil ring arrangement (33), to leave a second air gap. USE- For measuring torsion, torsional moment and/or rotation angle of two or more connected shafts.
