Title:
回転構造部材の負荷を測定する装置
Document Type and Number:
Japanese Patent JP4722393
Kind Code:
B2
Abstract:
The invention relates to a measuring device for detecting loads, especially torque, bending moment, and axial force applied to rotating components such as shafts, spindles, and/or pins with which changes if length caused by load are measured and determined in a non-contact manner with aid of at least one resistance strain gauge fixed on the component. For a non-contact feeding of supply energy for the resistance strain gauge and a likewise non-contact transmission of measured values to an evaluation device, an electronic rotor mechanism is provided which is arranged in one or several protective ring(s) ( 1 ) that encompasses the resistance strain gauge. For improving accuracy of the measurement and the informative capacity of the measuring results of the measuring device, the protective ring(s) ( 1 ) is (are) so arranged on the component that they are supported on one side or are formed deformable with respect to the component.
