Claims (1)
夫々に、各軸線に対して傾斜する端縁を互いに対
向させた磁性体製の２つの円筒を固設しており、
対向する端縁間の距離の変化に関連して入力軸に
作用するトルクを検出するトルクセンサであつて
、対向している一方の円筒の端縁の肉厚を他方の
円筒の端縁の肉厚より薄くしてあることを特徴と
するトルクセンサ。 Two cylinders made of magnetic material are fixed to each of the input and output shafts, which are connected via a torsion bar, and whose edges facing each other are inclined with respect to the respective axes.
A torque sensor that detects the torque acting on an input shaft in relation to a change in the distance between opposing edges, and the wall thickness of one opposing cylinder edge is measured by the thickness of the other cylinder edge. A torque sensor characterized by being thinner than thick.
