technical characteristics

Flexiblepintypecouplingsarepositive-locking,torsionallyelastic,flexible shaft couplings with rubbery-elastic transmission ele-ments.Theyarefailsafeandpluggable.

Buffermaterialandbuffergeometryensureanoptimalbalancingbetweenresilienceandrestoringactionaswellasagooddam-pingbehavior.

Flexiblepintypecouplingsareavailableinvariousseriesandde-signs.

Theassignmentofdrivinganddrivesideisarbitrary.Duetotheassembly,thepincouplinghasasmallcircumferentialbacklash.Aftertheinstallationofthecoupling,itisrequiredtoalignthedriveaspreciselyaspossiblebecausetheextentofthedisplacementshave a decisive influence on the service life aswell as on therestoringforcesandtorques.

Thepermissiblevaluesspecifiedonpage12definethe limit forthesumofalignmenterrorsandoperationaldisplacements.

The operating temperature range is between -40 °C (-25 °C ifconstructedofgraycastiron)and,dependingonthebuffermate-rial,upto+100°C(+120°Carepossibleforashorttime).

Flexible pin type couplings exhibit progressive spring characte-ristics.
