<p>PURPOSE:To furnish a torque meter with a gap eliminating function while covering a normal range, by realizing the simple constitution that utilizes a torsion bar having nonlinear characteristics. CONSTITUTION:Rotar 2 rotating in stator 1 is supported by hollow drivingl shaft 3 high in rigidity, and nonlinear torsion bar 4 is inserted into driving shaft 3 and fixed to driving shaft 3 at its internal end to transmit turning moment from its outside to the main turning shaft of a grindstone. Detection device 5 has markers 7 and 8, such as magnets, provided to pulley 6 fitted to driving shaft 3 and torsion bar 4 and detectors 10 and 11 provided to frame 9 of the motor detect those markers 7 and 8 to detect torque by a time shift in marker detection point in time between detectors 10 and 11 depending upon the torsion of torsion bar 4.</p> |
