→ 30 ° / min - 200 ° / min torque rate (recommended torque values of 180 ° / min).
→torsion speed 2.5r/min - 60r/min, torque increases by 30N.m /r
→loading speed 30r/min - 120r/min, analysis of displacement and swingingangle
→swinging speed: 2 °/s, swinging from maximum forward angle to maximum reverse angle, to test swinging torque
→0.5r/min-15r/min constant speed, swinging clockwise and counterclockwise for several revolutions, testing the rotating torque
→measure circumferential clearance of two universal joints from point 1 to point 2 and from point 3 to point 4, with accuracy within ±1
→To exert torque on the drive shaft or component and increase the torque value from 0N. m to specified torque, and then back to 0N.m, and then increase the value in reverseto specified torque and then back to 0N.m.The torsion speed of drive shaft is not more than 60 °/min, record the change of the angle value and plot Angle-Torque curve.
→Draw Torque-Angle stiffness curve, measure the maximum value of A-C Angle value or B-D Angle value to obtain the circumference clearance
