It can carry out dynamic torsional fatigue test and static torsional rigidity and strength test of various shafts and rods.It is suitable for the torsional fatigue and static torsional performance test of automobile drive shafts, constant velocity universal joints, ball cages, automobile half shafts, automobile drive axle housings and other parts.

　　Dynamic torsion can realize symmetrical cycle and asymmetrical cycle fatigue test.It can also simulate the dynamic torsional fatigue test of the constant velocity universal joint in the actual industrial and mining (loading state), and the installation angle of the workpiece can be rotated freely by 360°.During the test, the computer controls the test bench to proceed automatically according to the set parameters.The screen displays torque value, rotation angle value, swing frequency, swing amplitude, cycle number and loading waveform, etc., when the set number is reached, it will automatically stop and print the test results.

　　In the range of large torque and torsion angle of the test bench, static torsional rigidity and strength test can also be realized, and the printed stiffness value and static torsional rigidity curve, static torsional yield torque, yield torsion angle and torsion curve graph can be displayed.The testing machine has alarm protection functions such as motor overload, test torque, angle overload protection, shutdown, high oil temperature, and oil filter blockage.
