ABSTRACT:
A planer drive includes a sprocket wheel for a planing chain, the sprocket wheel having a secondary chain ring, and a driveshaft has a primary chain ring. On at last two circles juxtaposed at a predetermined distance, the primary chain ring has radial holes for clutch pins, conical friction segments attached to the clutch pins forming two revolving friction rings whose outside flanks work against an annular groove of the secondary chain ring. Between the two friction rings on the primary side, the secondary chain ring has a centrally engaging friction ring of appropriate taper which works against the inner flanks of the friction rings on the secondary side. The friction ring on the secondary side is mounted so as to be axially movable so that uniform engagement, reduced wear due to low specific contact pressure and better heat dissipation are assured while emergency operating properties are maintained.
