Measuring element of a loading transmitter for testing machines

摘要

The invention relates to a measuring element of a loading transmitter for testing machines. It is the object of the invention to measure at the same time the torsional loading and the loading by means of the linear axle force without reciprocal influence of the measured signals on each other. The invention consists in that the periphery of a metal disc, which is formed geometrically in one piece from two concentric rings and radial webs which form measuring columns arranged between these rings, is connected to its middle part, which is provided for connection to the test piece to be tested, by means of radial measuring columns, in that these measuring columns are provided with tensometers on their end faces and their side faces, in that tensometers T1 to T8 mounted on the end faces of the measuring columns are connected in a first bridge whose one branch is always formed by the tensometers mounted on identical end faces of the opposite measuring columns and in that tensometers T9 to T16 mounted on the side surfaces of the measuring columns are connected in a second bridge whose one branch is always formed by the tensometers mounted on the opposite sides of the opposite measuring columns.
