Industrial SU Form
The SU Kind coupling features a single flex plane with two hubs and also a single disc pack. It’s appropriate for angular and axial misalignment only. Two SU couplings are often mixed with a shaft
to create a floating shaft coupling. The shaft can be hollow for prolonged light fat floating shaft couplings.
Industrial SX Kind
This is the common coupling kind that contains two hubs, a stock length spacer made to meet sector typical lengths, and two unitized disc packs. The coupling has two flex planes, one at each disc pack, permitting this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is accessible in six and 8 bolt types and bore sizes up to 13 inches (330mm) about the largest size. Customized spacer lengths is usually produced to meet particular shaft separations needed for particular applications. The SX coupling may be fitted with overload bushings to protect the disc packs in over torque disorders and can act as an anti-flail gadget. SX couplings are assembled at the time of set up around the equipment exactly where the coupling will be in services.
Industrial DI Kind
The DI Form coupling features a “Drop-In” spacer assembly which is assembled at the factory. The coupling includes two hubs as well as a spacer assembly comprising from the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted for the spacer and guard rings on the factory utilizing the torque values suggested by Lovejoy for the disc pack bolts. Together with the hubs mounted around the shafts, the complete disc pack assembly is usually “Dropped In” location concerning the two hubs. The hubs are piloted to guarantee proper centering on the spacer assembly. This piloting serves as an anti-flail function and aids within the coupling’s ability to meet the stability requirements mandated by API. This type coupling is developed to meet the stability and anti-flail prerequisites specified in API-610.
Oversized, or Jumbo, hubs can be found for use with the DI Type coupling to allow for more substantial bore sizes on most DI coupling sizes. This permits for the use of smaller DI couplings in applications the place a smaller sized size coupling can nevertheless accommodate the application torque.
Industrial SXC Type
The SXC Style could be the near coupled variation on the SX Variety coupling. The SXC is much like the SX coupling in the disc packs are attached when the coupling is set up. During the close coupled units, the hubs are turned inward and are mounted inside the spacer. Note that with all the hubs within the spacer, the maximum bore permitted within the hub will be decreased. The SXC couplings is often employed with 1 or the two hubs turned outward to allow the coupling to accommodate diverse shaft separations.
Industrial SXCS and SXCST Forms
The SXCS and SXCST Styles have split spacers as well as the disc packs might be serviced or removed without moving the hubs about the shafts and without moving the equipment. The SXCS Variety has the bolts that connect the hubs towards the split spacer set up in the ends in the couplings. The SXCST possess the bolts set up from within the spacer pointing outward in the direction of the hubs.
