The US flexible coupling specialist, Lovejoy has published a six-page
gatefold brochure describing its 'jaw in-shear' (JIS), '6-Pin', rotating
shaft elastomeric coupling range. The new publication features a
photographic sequence demonstrating the benefits of the 6-Pin mechanism,
which avoids the need to disassemble hubs and allows blind fitting in
confined spaces.
The JIS 6-Pin element and locking ring fit Lovejoy's industry-standard
jaw couling hubs, converting them from normal in-compression service to
in-shear service. The jaw in-shear design positions the driving and
driven jaws in separate planes, using a wider spider moulded as a
wrap-around strip that spans a shear-plane between them. This allows the
spider to act as a sort of 'fuse' to prevent system damage in the event
of torque overload.
