A new six-page colour catalogue from Lovejoy explains key features and provides full dimensional, performance rating and service factor data for Lovejoy's next-generation JIS jaw in-shear 6-pin rotating-shaft elastomeric couplings.
In addition to presenting Lovejoy's patent-pending, 6-pin mechanism for locking the torque-transmitting elastomeric element (spider) in place, the catalogue includes six larger coupling sizes recently added to extend maximum bore up to 229mm with maximum torque of 41,428Nm.
It also details a JIS spacer-type series added to provide nonlubricated, drop-in replacements for grid spacer couplings.
The new catalogue features a four-photo sequence demonstrating easy, no-tools spider replacement resulting from Lovejoy's 6-pin design, which eliminates any need to disassemble hubs, minimizes maintenance downtime and enables "blind fit" in confined spaces.
It also lists part numbers and list prices separately for the JIS 6-pin element and locking ring.
Both pars fit Lovejoy's industry-standard Jaw coupling hubs, converting them from normal in-compression service to in-shear service, and the new element works with Lovejoy's earlier JIS locking ring design.
This interchangeability simplifies the user's parts purchasing and stocking requirements.
Dimensional data for all 16 sizes of JIS 6-pin couplings and 32 sizes of spacer types is presented in tabular form, keyed to mechanical drawings on the same page for quick reference.
To aid in selection, separate tables show service factors for type of application, operation period and starts per hour, plus ratings for bore, torque, misalignment, weight and rotational speed.
Unlike standard jaw couplings, which position the elastomeric spider in compression between driving and driven jaws rotating in the same plane, the jaw in-shear design positions 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 fuse to prevent system damage in the event of torque overload.
A wide, flat stainless steel locking ring slides on over the strip to hold it in place.
Six tooth-like pins extending inward around both sides of the ring, three per side, keep the ring straddled over the elastomeric strip.
Three crosswise grooves moulded into the strip around its perimeter provide passageways for the pins as the ring slides on.
When the installed ring is rotated slightly, the pins latch behind small bumps moulded along one side of the strip, preventing return rotation.
