This application relates to the field of
control rod drive mechanism testing technology, specifically, to a drive mechanism testing
system employing an overrunning
clutch. The
system includes a base, a fixed bracket, a long shaft, a photoelectric
encoder, a
magnetic powder brake, a
torque sensor, an
inertia disk, an overrunning
clutch, a control mechanism, and a drive mechanism. The photoelectric
encoder is fixed to the left side of the photoelectric
encoder bracket; the
magnetic powder brake is positioned between the photoelectric encoder bracket and the
inertia bracket, and the
torque sensor is positioned outside the
magnetic powder brake; the long shaft is positioned between the
inertia bracket and the
clutch bracket; the inertia disk is connected to the long shaft via a key; the overrunning clutch is positioned between the clutch bracket and the mechanism bracket; the control mechanism is located above the overrunning clutch; and the drive mechanism is fixed to the right side of the mechanism bracket. This application simplifies the operation of the drive mechanism by utilizing the overrunning clutch, requiring only the detection of the drive mechanism's initial and final positions, and using the
time difference to calculate the drive mechanism's reset time.
