The CD series of mechanical
wrap spring clutches are
available in three configurations:

1. The CDOR Series One-Way, or Overrunning clutch
2. The CDSS Series Start-Stop clutch
3. The CDSR Series Single Revolution clutch

CDOR Series

Overrunning Clutch The CDOR clutch will transmit torque in one direction. When the input hub is stopped, the load is free to rotate or overrun. The CDOR Clutch will transmit torque in the specified direction to the rated value, but only exhibits a small drag torque value in the reverse direction. The CDOR Series clutches should be considered for applications where anti-overhaul or no-back properties are desired.

CDSS Series

Start-Stop Clutch The CDSS Clutch will transmit torque when the stop collar is released. When the collar is free, the spring is allowed to grip both the hub and shaft together. To disengage the clutch, the collar is stopped. With the collar stopped, the spring releases its grip between the hub and shaft allowing the input to freely rotate. CDSS clutches provide a random stop position. Stopping position is determined by system inertia and drag torque.

CDSR Series

Single Revolution Clutch The CDSR Clutch will transmit torque when the stop collar is released. When the collar is free, the spring is allowed to grip both the hub and shaft together. The braking or deceleration begins when the collar is stopped. To stop the CDSR Series clutches, braking torque is limited to 10% of the rated torque.

Accumulating Conveyor Clutches

The CE-30/31 and CD-80/81 clutches are the most popular clutches for CDLR zone accumulator applications. These heavy duty clutches are designed for accumulating conveyors that are mechanically actuated. They are offered with two styles of output hubs: plain (for weld-on sprockets) and drilled/tapped (for bolt-on sprockets). Also see Conveyor E - 7 or E - 8.
