Bores up to 300 mm. A multitude of standardized bore diameters are available with short delivery times. Application example Complete Freewheel FBF 72 DX as an overrunning clutch in the drive of a meat processing machine (chopper). During the mixing process, the gear motor drives the bowl via the gear wheel drive and simultaneously the knife shaft via the belt drive and the locked freewheel. In the cutting process, the knife shaft is driven by a second motor at high speed. By doing so, the inner ring overruns the outer ring that is driven by the gear motor and the gear motor is automatically disengaged. With the high speed of the inner ring in freewheeling operation, the type sprag lift-off X is used; the sprags work in freewheeling operation without contact and hence are wear-free. The customer attachment part is centered on the external diameter D and then bolted on to the face via the flange. The tolerance of the shaft must be ISO h6 or j6 and the tolerance of the pilot diameter D of the attachment part must be ISO H7 or J7. Freewheel size FBF 72, type with sprag lift-off X and 40 mm bore: • FBF 72 DX, d = 40 mm When ordering, please also specify the freewheeling direction of the inner ring when viewed in direction X: • counterclockwise free or • clockwis
