Zusammenfassung: | To provide a precise torque converter even at a high-speed rotation.SOLUTION: In a torque converter 1 that has a hollow cylindrical strain part 2 and converts torsional torque operating on the strain part 2 to an electric signal, plural strain-sensitive resistors G (G1 to G8) are welded to the strain part 2, and the strain-sensitive resistors G (G1 to G8) are disposed in a pair while an angle θ formed by a center axis AX of the strain part 2 and a direction of the maximum sensitivity of the strain-sensitive resistors G (G1 to G8) is determined by a Poisson ratio of the strain part 2.SELECTED DRAWING: Figure 2
【課題】高速回転においても精確なトルク変換器を提供することを課題としている。【解決手段】中空円柱形の起歪部2を備えて起歪部2に作用するねじりトルクを電気信号に変換するトルク変換器1であって、起歪部2には複数の感歪抵抗体G(G1〜G8)が添着され、感歪抵抗体G(G1〜G8)は、起歪部2の中心軸AXと感歪抵抗体G(G1〜G8)の最大感度方向のなす角度θが、起歪部2のポアソン比から定められて対をなして配置される。【選択図】図2 |
