Application Example
Two Complete Freewheels FR CA with gear coupling as overrunning clutches in the drive
unit of a tube mill with additional auxiliary drive. A freewheel FRSG 600 CA 2.0 (Freewheel 1) is arranged between the main drive and the right angle gear box. A freewheel FRZ 500 CA 1.5 (Freewheel 2) with sprag lift-off Z (page 26) is positioned between the auxiliary drive and the right angle gear box. If the auxiliary drive is operating,
Freewheel 2 works in the driving operation and the Freewheel 1 overruns at a low
speed (freewheel operation). When driving via the main drive, the unit is driven thru Freewheel 1 (driving operation) Freewheel 2 overruns and automatically disengages the auxiliary drive (freewheeling operation). With the high speed, the type with sprag lift-off Z is used. There is no contact of the sprags during freewheeling and
therefore no wear.
