Testing Effective and Maximum Torque for the Metal Material Coupled by Interference Fit

Abstract:

The precision torque instrument was researched and manufactured successfully by Taizhou Institute of Measurement Technology (TIMT). The twisting performance can be measured and evaluated by metal material and coupled by interference fit. Metal material twisting analysis can be used for analysis the part by metal material and coupled by interference fit. Fixing a displacement sensor on one coupling part, and fixing one hold back on another coupling part, this structure measures the twisting angle. At the same time, the dynamometer sensor connects one coupling part through level arm, and other coupling part connects instrument activities end. The action force presses the dynamometer through instrument activities end, coupling part, instrument fixed end and level arm. The dates of displacement and dynamometer sensor will be put into the computer through synchronizer. The TorqueAngle Graph will be established by these data. The maximum torque T_m and effective torque T_e will be established from the TorqueAngle Graph.
