IPC: G01L3/10
Filed: 1991-03-19
Abstract: PURPOSE:To realize a torque detecting apparatus in the compact and simple constitution and to prevent detecting errors due to the mounting operation or change with time. CONSTITUTION:A position signal is recorded in a rotary shaft member 10 made of magnetic material via a set of magnetic heads 12a, 12b separated a predetermined distance L in the axial direction. The phase difference of position signals reproduced via the magnetic heads 12a, 12b is detected. The torque acting to the rotary shaft member 10 is calculated based on the detected phase difference. In other words, the torque is detected by recording/reproducing position signals with the utilization of the magnetic characteristic of the rotary shaft member 10 itself. Accordingly, it becomes unnecessary to perform mechanical processing or surface treatment of the rotary shaft member to detect the torque or to add a special mechanism part, such as a slip ring or the like, not alike tone prior art. Moreover, the initial phase shift generated between the magnetic heads can be easily corrected by recording/updating the position signals.
