COUPLINGS

SFH MODELThe Largest Model Among SERVO FLEX:Metal Plate Spring CouplingsThe maximum flange outer diameter is ø 262 mm and the permissible torque is 8000 N·m.The most rigid S type has a torsional stiffness of 10,780,000 N·m/rad at maximum.This series is available with the high-flexibility G type, where a high-rigidity single-element S type andtwo elements are positioned respectively and are jointed with a fl oating shaft at the middle part.This is also available for length setting according to customers’ requests.PLATE SPRING OF IDEAL FORMSERVO FLEXSFHHigh Rigidity, High FlexibilityA high transmission torque has been realizedby thorough analysis using the advancedfinite element method (FEM) and torquetransmission using six bolts.This is available with a choice between thehigh-rigidity type with one element and theother type with a configurable spacer length.TORQUETHRUSTBENDINGRADIAL56COUPLING_E_56_65new.indd 56www.feyc.es9/15/10 4:28 PM
