The general purpose disc coupling can
be easily adapted to offer "spark Free"
operation for use in explosive
enviroments. This achieved by
replacing the standard steel overload
washers with non-sparking Monel.
This refers to a feature introduced to
restrain the coupling spacer in the
event of an element disc failure. In
practice, the overload-washer / bolt
system adopted in Bibby Turboflex
general purpose disc couplings serves
this requirement. However, if required
a secondary anti-flail feature can be
incorporated on the DJ range of units.
Bibby Turboflex disc couplings can be
adapted to offer a limited end float
capability. The standard limitation is
±3mm for a spacer coupling. Other
limits are available on request. Please
note that the non-linear axial stiffness
of disc couplings means that, under
most circumstances, they inherently
limit the float of a motor rotor within
it’s bearing stops. As such, the addition
of a limiting end float system is
frequently not required. Please consult
Bibby Turboflex for further
information.
