The machine is designed for test clutch disc assembly torsional characteristics. The computer automatically finish all test procedures and plot the torsional characteristic curve and get hysteresis value in any angle according to customers’ demand. It is applied to the enterprises and clutch production line detection, research and development and quality control departments.
Test items
Limit toque: Mmax
Limit torsional angle: θmax
Torque hysteresis value Mh in given angle of rotation
Torsional stiffness Ca in the range of given rotation angle
Torque inflexion
Torsional characteristic curve of main damper
Torsional characteristic curve of predamer (optional)
The forward value and backward value and mean value and hysteresis value at I II point of forward and opposite directions of main and pre damper. (optional)
Characteristics:
Integrated machine structure of both dampers automatically exchanging control test, one installation could complete two tests of both main damper and pre damper.
Servo motor drives gear reducer and transfers forward and opposite torque to disc assembly to produce torque.
Angular photoelectric encoder moves with hub at forward and opposite torque and picks up the angular signal.
Windows system, data base, high precise torque sensor and high precise measurement board
All test results and quality determination can be saved and inquired.
The curve shows on the display and the test items can be optioned save and printed out and exported to Excel.
