Industrial SU Style
The SU Style coupling features a single flex plane with two hubs and a single disc pack. It can be appropriate for angular and axial misalignment only. Two SU couplings are sometimes combined that has a shaft
to generate a floating shaft coupling. The shaft might be hollow for lengthy light fat floating shaft couplings.
Industrial SX Kind
This can be the typical coupling sort that involves two hubs, a stock length spacer created to meet sector standard lengths, and two unitized disc packs. The coupling has two flex planes, one particular at every single disc pack, enabling this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is obtainable in six and 8 bolt types and bore sizes up to 13 inches (330mm) within the largest dimension. Customized spacer lengths is usually manufactured to meet unique shaft separations necessary for precise applications. The SX coupling might be fitted with overload bushings to protect the disc packs in more than torque ailments and can act as an anti-flail gadget. SX couplings are assembled in the time of installation over the equipment where the coupling will be in service.
Industrial DI Form
The DI Form coupling includes a “Drop-In” spacer assembly which is assembled on the factory. The coupling includes two hubs in addition to a spacer assembly comprising of the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted to the spacer and guard rings with the factory making use of the torque values encouraged by Lovejoy to the disc pack bolts. With the hubs mounted over the shafts, the complete disc pack assembly may be “Dropped In” area concerning the two hubs. The hubs are piloted to make certain good centering of the spacer assembly. This piloting serves as an anti-flail attribute and aids while in the coupling’s ability to meet the stability requirements mandated by API. This style coupling is intended to meet the balance and anti-flail necessities specified in API-610.
Oversized, or Jumbo, hubs can be found for use using the DI Style coupling to allow for more substantial bore sizes on most DI coupling sizes. This allows for the utilization of smaller DI couplings in applications in which a smaller size coupling can nevertheless accommodate the application torque.
Industrial SXC Style
The SXC Kind would be the near coupled variation on the SX Style coupling. The SXC is just like the SX coupling in that the disc packs are attached when the coupling is set up. While in the shut coupled units, the hubs are turned inward and therefore are mounted inside the spacer. Note that using the hubs inside the spacer, the maximum bore allowed during the hub will be decreased. The SXC couplings can be applied with one particular or the two hubs turned outward to allow the coupling to accommodate distinct shaft separations.
Industrial SXCS and SXCST Varieties
The SXCS and SXCST Kinds have split spacers plus the disc packs can be serviced or eliminated with no moving the hubs around the shafts and with out moving the tools. The SXCS Kind has the bolts that connect the hubs towards the split spacer set up in the ends of the couplings. The SXCST have the bolts put in from within the spacer pointing outward in the direction of the hubs.
