Important Features
Fenner Tire Couplings provide all the desirable features of an ideal flexible coupling, including Taper Lock fixing. They are 'torsionally elastic', offering versatility to designers and engineers with a choice of flange combinations to suit most applications.
The flanges are available in either 'F' or 'H' version Taper Lock fitting or bored to size 'B'. ( Click for illustration )
With the addition of a spacer flange, the coupling can be used to accommodate standard distance between shaft ends (DBSE) Click for illustration and facilitate pump maintenance.
Fenner Tires are available in natural rubber compunds for use in ambient temperatures between -500C to +500C.
Polychloroprene rubber compounds are available for use in adverse operating conditions, e.g. oil or grease contamination and can be used in temperatures of -150C to +700C.
FRAS Tires are available for use when fire resistance and antistatic (F.R.A.S.) properties are required.
Torque Range
Nominal: 12,606 Nm.
Max.: 42,740 Nm.
Bore Range
Bore diameters upto 190 mm
Handles parallel, angular and axial displacements, either singly or in any combination. Can accommodate parallel misalignment upto 6 mm, angular misalignment upto 40 and end float upto 8 mm.
Torsionally Soft
Cushions against destructive shock loads protecting the complete system, preventing expensive breakdowns and lengthens machine life.
Free of Backlash
Does not create 'snatch' or take up of the drive.
Requires neither special tools nor skilled labor to assemble. Alignment is quickly checked by placing a straight edge across outside diameter of flanges. The split flexible Tire is then positioned in the flanges and the screws tightened into place.
Reduces vibration and torsional oscillations developed in internal combustion engines, the amplitude of which increases greatly at critical points in the speed range. Fenner Tire coupling dampens these destructive vibrations.
Because there are no moving parts, no lubrication is required. Periodic inspection of the Tire is all that is required.
Use of natural or Neoprene rubber compounds makes the Fenner Tire Coupling suitable for use in most conditions. For fire hazard areas the F.R.A.S. Tire is recommended. This allows free flow of electricity between the two shafts to avoid static electricity build up.
