Product Description

Complete Freewheels FBL
with shaft coupling for large shaft misalignments
with sprags, available in three types
 
Features
Complete Freewheels FBL with RINGSPANN shaft coupling are sealed sprag freewheels with
ball bearings for coupling two shafts. They are supplied oil-filled and ready for installation
The freewheels FBL are used as:
 Overrunning Clutches
In addition to the standard type, two other types are available for extended service life.
Nominal torques up to 8 000 Nm. Bores up to 140 mm. Many standard bores are available. The torsionally stiff shaft coupling can accept large radial and angular misalignments, without
reactive forces affecting neighbouring bearings. We can provide you with performance data
upon request.

Application example
Complete Freewheel FBL 82 SFZ as an overrunning clutch in the drive unit of a conveyor belt
system with additional creep drive. The free - wheel with shaft coupling is arranged in between the main motor and the creep drive. When the creep drive operates, the freewheel is in driving operation and drives the belt at low speed. In normal operation (freewheeling operation), the main motor drives and the outer ring overruns, whereupon the creep drive is automatically
disengaged. With the high speed here, the type sprag lift-off Z is used; the sprags work in freewheeling operation without contact and hence are wear-free.
 
Mounting
The flexible disk of the shaft coupling must be axially free when fitted so that the ball bearings
in the freewheel are not distorted due to heat expansion. 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

bore in the shaft coupling:
