Description of Suffix:
SF - Standard Type for Universal Use
Other salient points to be noted:
• The maximum transmissible torque is 2 times the specified nominal torque
• For bore d1: Keyway according to DIN 6885
• For bore d1: Keyway width tolerance JS10
• For bore d3: Keyway according to DIN 6885
• For bore d3: Keyway width tolerance P9
Features:
• Handles nominal torques up to 160,000 Nm
• Available with bores up to 300 mm; many standard bore sizes readily available
Application as: Overrunning Clutch
Application Example:
• Two Complete Freewheels FBE 72 with shaft coupling are used as overrunning clutches in the drive unit of a tube mill with an auxiliary drive
• A standard FBE 72 SF (Freewheel 1) is installed between the main drive and the angular gear
• A FBE 72 LZ (Freewheel 2), equipped with sprag lift-off Z, is installed between the auxiliary drive and the angular gear
• In auxiliary power mode, the auxiliary drive powers the system through Freewheel 2 (driving mode), while Freewheel 1 operates in freewheeling mode at low speed
• In main motor mode, the system is powered via Freewheel 1 (driving mode), while Freewheel 2 automatically overruns and disengages the auxiliary drive (freewheeling mode)
• The sprag lift-off Z type in Freewheel 2 allows for contact-free, wear-free operation at high speed during freewheeling
Mounting:
• The shaft coupling can be installed on either the right or left side of the freewheel, depending on the required freewheeling direction
• The shaft tolerance must comply with ISO h6 or j6
