发明名称 POWER MEASURING APPARATUS
摘要 PURPOSE:To make it possible to hold measuring accuracy even if the torques of machines to be measured different in rated output are measured with one dynamometer, by measuring driving torque by a load cell through the torque arm provided to an oscillator. CONSTITUTION:A load cell 10a having large measuring capacity and a load cell 10b having small measuring capacity are mounted between a torque arm 3 and a base 6 through a rod 11 so that the former is present in an upper side and latter is present in a lower side. The end part of the uppermost rod 11 is engaged with the arm 3 in a revolvable manner through a rod end 12 and a reamer bolt 13 and the lower part of the load cell 10b is fixed to the base 6. Two engaging pieces 14 are fixed to the rod 11 between the load cells 10a, 10b so as to provide a gap T2 and a fixing stopper 15 having a plate thickness T1 is fixed to a support plate 16 in the gap T2 so as to provide gaps t1, t2 between the engaging pieces 14 and the stopper 15. By this constitution, torque can be measured automatically by the load cell having an optimum characteristic even when the torque of a machine to be measured different in rated output is measured and measuring accuracy can be held.
