AUTOGARD SERIES 200 – TORQUE LIMITER

Re-engagement
Re-engagement occurs in one of three ways depending upon which reset type is selected.

Type AC – Automatic Random Reset
The ball detents in the drive plate and the slide plate, as well as the retaining holes in cage plate are equally spaced on the same pitch circle diameter so that the balls will roll into the next detents after tripping in either direction. Immediate shutdown is required to prevent wear of the detents.

Type ACT – Automatic Synchronous Reset
The are positioned in a scattered pattern so that the balls must return to their original position before they can reset.
Re-engagement will occur within two revolutions in either direction. Immediate shutdown is
required to prevent wear of the detents.

Type AF – Free Wheeling Disengagement
As with the AC the detents in drive plate and slide plate are equally spaced. The retaining holes in the engaging plate are elongated so that as the balls roll from the detents they can follow a cam profile onto a different running track away from the detents. The AF can run at higher speeds as the balls will not ratchet in the detents. Re-setting is achieved by manually locking the plates and reversing the drive.
