Electrical equipment of the test bench and safety clutches adjustment

Among the types of safety clutches tests, operational life testing is singled out, which verifies the reliability of the clutch during multiple operations and change of the clutch settings during multiple operations. The task of rational use of electricity by a test bench during operational life testing is of great importance. A rational scheme of the electrical equipment of the test bench for operational life testing and safety clutches adjustment is given. The circuit with return circulation of the load power of the safety clutch is applied in the equipment of the test bench, which saves the energy consumed for the testing. Patterns of adjustment of rotational speed and the load torque of the proposed device are considered. It is of interest for designers of test equipment and specialists in safety clutches adjustment.
