A ratchet torque limiter is a device able to interrupt the transmission of power in the event of a torque peak or overload that exceeds the setting. The torque limiter is automatically re-engaged after the cause of the overload is removed. Ratchet torque limiters are generally employed to protect implements subject to constant or alternating torques from overloads. The setting is normally two to three times the median torque to be transmitted.  During operation of the device, the spring loaded ratchets try to reengage the grooves
in the housing. This generates small torque peaks and noise. This noise warns the rator that the device is engaged. Once the device is slipping, the user should promptly stop the PTO to avoid excessive wear.
Ratchet torque limiters should be used only on drivelines operating at speeds less than 700 min-1. Ratchet torque limiters may be supplied in either symmetrical or one-way types.
One-way ratchet torque limiters permit higher settings compared to symmetrical units with an equal number of ratchets. When rotated opposite the normal working direction, oneway ratchet torque limiters transmit only 15% of the torque setting.
Standard one-way ratchet torque limiters are designed to operate on a driveline with counter-clockwise rotation. This is the typical rotation of a ratchet torque limiter installed on the implement side of a primary driveline connecting a tractors’ rearmounted PTO (clockwise rotation viewed into the shaft) to the implement PIC (counterclockwise rotation).

 

Symmetrical and one-way ratchet torque limiters are supplied in different versions, with different lubrication frequencies (either 50 hours or seasonal lubrication). Version SA (one-way) and version LN (symmetrical) have a 50 hour lubrication interval (NLGI 2 grease). SA1, SA2, LN1 and LN2 have a push-pin type connection to the splined shaft. SA3, SA4, LN3 and LN4 have a ball collar type connection.
