with sprags, available in three types

Features

Complete Freewheels FBE with flexible shaft coupling are sealed sprag freewheels with ball

bearings for coupling two aligned shafts. They are supplied oil-filled and ready for installation.

The freewheels FBE are used as:

Overrunning Clutches

In addition to the standard type, two other types are available for extended service life.

Nominal torques up to 160 000 Nm. Bores up to 300 mm. Many standard bores are available.

The material of the flexible coupling element is oil-resistant. We can provide you with performance data for the flexible shaft coupling upon request.

Application example

Two Complete Freewheels FBE 72 with shaft coupling as an overrunning clutch in the drive

unit of a tube mill with additional auxiliary drive. A freewheel FBE 72 SF, standard type (freewheel 1) is arranged between the main drive and the angular gear. However, a freewheel FBE 72 LZ, type with sprag lift-off Z (freewheel 2) is arranged between the auxiliary drive and the angular gear. If the gear motor is driving in the auxiliary power mode, freewheel 2 works in driving operation and freewheel 1 overruns at a low speed (freewheeling operation). When driving via the main motor, the unit is driven via freewheel 1 (driving operation). Freewheel 2 overruns and automatically disengages the aux-iliary drive (freewheeling operation). With the high speed, the type with sprag lift-off Z is used; the sprags work in freewheeling operation without contact and hence are wear-free.

Mounting

The shaft coupling including the fastening screws are supplied loose. Depending on the desired freewheeling direction, the shaft coupling can be fitted on the right or the left of the

freewheel. The tolerance of the shaft must be ISO h6 or j6.

Example for ordering

Freewheel size FBE 107, standard type with 60 mm bore in the freewheel and 55 mm bore

in the shaft coupling:

• FBE 107 SF, d1 = 60 mm, d3 = 55 mm
