The phenomenon that lagging behind input shaft, due to the presence of part processing, rigging error and load and temperature change, return difference is inevitable
's.
Speed reducer backlash and stiffness excitations should lock speed reducer input terminal, apply positive and negative nominal torque, record to output end
Torque angle corresponding relationship when positive detorsion.Wherein the positive and negative differential seat angle of+3% nominal torque is backlash, under+100% nominal torque
Differential seat angle is rigidity.When speed reducer small rated torque is small, loaded using standard arm of force cooperation counterweight also analog merely, still
If servo motor cost is too big when thousands of Nm even tens of thousands of Nm, if increased between servo motor and tested motor plus with speed reducer
Add torque that can also improve torque, but in reversely switching load after forward direction is loaded into nominal torque value, due to common speed reducer
And unavoidably there is gap between shaft coupling, switch turn to when can locked-in torque can be mutated and to form inflection point and cause detection error.
