Fxm 76 -25 Integrated Freewheels for Bolting to The Face with Sprag CZPT -off

Integrated Freewheels FXM
for bolting to the face
with sprag lift-off X

 
Features
Integrated Freewheels FXM are sprag freewheels without bearing support and with sprag
lift-off X. The sprag lift-off X ensures a wear free freewheeling operation when the inner ring rotates at high speed. The freewheels FXM are used as:
 Backstops
 Overunning Clutches
for applications with high speed freewheel ing operation and when used as an overrunning
clutch with low speed driving operation. Nominal torques up to 888 000 Nm. Bores up to 460 mm. Many standard bores are CZPT .
 
Sprag lift-off X
Integrated Freewheels FXM are equipped with sprag lift-off X. The sprag lift-off X is used for
backstops and overrunning clutches, provided that in freewheeling operation the inner ring is
rotating at high speed and providing with overrunning clutches that the driving operation
is conducted at low speed. In freewheeling operation, the centrifugal force FC causes the
sprag to lift off from the outer track. In this operating state, the freewheel works wear-free,
i.e. with unlimited service life.
 
Figure 64-2 shows a freewheel with sprag liftoff X in freewheeling operation. The sprags,
which are supported in a cage connected with the inner ring, rotate with the inner ring. The
centrifugal force FC that is applied in the center of gravity S of the sprag turns the sprag counterclockwise and rests against the support ring of the cage. This results in the gap a between the sprag and the outer track; the freewheel works with out contact. If the inner ring speed decreases to such an extent that the effect of the centrifugal force on the sprag is less than that of the spring force FF , the sprag again rests on the outer ring and the freewheel is ready to lock (figure 64-3). If used as an overrunning clutch, the driving speed must not exceed 40% of the lift-off speed.

Application example
Integrated Freewheel FXM 170 – 63 MX with end cover as backstop fitted to the end of the first
intermediate shaft of a spur gearbox in the drive of an inclined conveyor belt. In the case of a
motor stop, the conveyor belt must be held securely so that the conveyor goods do not pull
the belt backwards and possibly cause serious damage. Due to the high shaft speeds in normal operation (freewheeling operation), the sprag lift-off X ensures a contactless and hence wear free continuous operation.
 
Two Integrated Freewheels FXM 120 – 50 MX in the gearbox unit of a vertical bucket conveyor. Alongside the main drive, the bucket conveyor has a creep drive, which can be moved at a low
speed if maintenance work needs to be carried out. The freewheel arranged between the creep drive and the main drive works as an overrunning clutch. When the creep drive operates, the freewheel is in driving oper ation. In normal oper ation, when driving via the main drive, the
inner ring of the freewheel overruns at high speed and automatically disengages the creep
drive. The CZPT freewheel that is arranged on the end of the first intermediate shaft of the
main gearbox, works as a backstop and prevents the bucket conveyor from running back
when the unit is at a standstill.
 
 
Integrated Freewheel FXM 76-25 NX as an overrunning clutch between the creep drive and the main drive of a cement mixer. When the creep drive operates, the outer ring is driven by the shaft coupling. The freewheel works in driving operation and drives the unit at a low speed via the main gearbox. In normal operation (free – wheel ing operation), the inner ring overruns at high speed and the creep drive is automatically disengaged. With the high shaft speed, the type sprag lift-off X is used; the sprags work in freewheeling operation without contact and
hence are wear-free. The arrangement of the seals between the freewheel and the main
gearbox is advantageous. In freewheeling operation, this is at a standstill and hence generates
no addi tion al friction-related temperature rise.
