Claims (1)
硬度をもつた鋼球を円周上に複数個配置し、これ
をボルトと被締結部材との間に組み入れ、ボルト
に働く軸力を２つの部材間に配置した鋼球がこの
部材に押し込まれる荷重として作用させ、この２
つの部材間距離の変位をボルトの軸力に換算して
表示することを特徴としたボルト軸力表示装置。 A plurality of steel balls with hardness sufficiently higher than those of these members are arranged on the circumference between two members, and these are incorporated between the bolt and the member to be fastened, so that the axial force acting on the bolt is divided into two. A steel ball placed between the members acts as a load to be pushed into this member, and this two
A bolt axial force display device that converts the displacement of the distance between two members into the axial force of the bolt and displays it.
