End Play Eliminated
The
solution: a flexured area allowing the shaft to angularly deflect and
keep pinion and gear in mesh. Please note the square shaft – another
example of Helical’s flexibility in meeting the designer’s desires.
General Details
Between taxiing and takeoff, an aircraft engine is subjected to a battery of forces – imposing continuous misalignment on the aircraft fuel pump drive. Helical’s challenge was to design a Flexure for the aircraft fuel pump drive that would eliminate axial end play – yet, when needed, still allow absolute tooth engagement between pinion and gear. The solution: a flexured area allowing the shaft to angularly deflect and keep pinion and gear in mesh. Please note the square shaft – another example of Helical’s flexibility in meeting the designer’s desires.
