Universal joint torsional fatigue testing machine

　　The universal joint torsion fatigue testing machine is a high-precision equipment for testing the torsion and torsion fatigue performance of universal joints and other parts. Using advanced electro-hydraulic servo or microcomputer control system, symmetrical and asymmetrical cyclic fatigue tests can be realized, and the dynamic torsional fatigue test of universal joint under actual working conditions can be simulated. The equipment has high-precision torque and angle measurement function, which can display parameters such as torque value, rotation angle value and swing frequency in real time, and can automatically draw test curves. Its main engine structure is durable and made of high-quality steel to ensure long-term stable operation. In addition, it also has a variety of safety protection functions, such as motor overload protection, torque overload shutdown and so on.

　　1. The universal joint torsional fatigue testing machine is used for the research of normal temperature torsional fatigue life test and fatigue performance test of various rigid universal joints, unequal velocity universal joints, constant velocity universal joints, ball-fork universal joints and equal universal joints. Including dynamic fatigue test, static torsion test and normal temperature cycle life test.

　　2. Control introduction: test force control, angle control and frequency control. During the test, the load-time curve, load-angle curve and fatigue cycle curve of the specimen are displayed in real time. Display frequency and fatigue times. Stop automatically for a set number of times, and stop automatically if the specimen is damaged, and record the test results.
