Industrial SU Form
The SU Style coupling includes a single flex plane with two hubs along with a single disc pack. It is actually suitable for angular and axial misalignment only. Two SU couplings are sometimes combined having a shaft
to create a floating shaft coupling. The shaft could be hollow for prolonged light weight floating shaft couplings.
Industrial SX Kind
This really is the normal coupling style that involves two hubs, a stock length spacer created to meet market standard lengths, and two unitized disc packs. The coupling has two flex planes, one at each and every disc pack, enabling this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is accessible in 6 and eight bolt models and bore sizes as much as 13 inches (330mm) on the greatest dimension. Custom spacer lengths could be produced to meet distinctive shaft separations required for unique applications. The SX coupling can be fitted with overload bushings to safeguard the disc packs in more than torque disorders and may act as an anti-flail device. SX couplings are assembled at the time of set up around the equipment wherever the coupling will probably be in services.
Industrial DI Type
The DI Type coupling includes a “Drop-In” spacer assembly that is definitely assembled in the factory. The coupling consists of two hubs and also a spacer assembly comprising from the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted on the spacer and guard rings at the factory working with the torque values recommended by Lovejoy for your disc pack bolts. With the hubs mounted on the shafts, the complete disc pack assembly may be “Dropped In” place amongst the two hubs. The hubs are piloted to make certain suitable centering on the spacer assembly. This piloting serves as an anti-flail attribute and aids in the coupling’s ability to meet the stability requirements mandated by API. This type coupling is developed to meet the stability and anti-flail needs specified in API-610.
Oversized, or Jumbo, hubs can be found for use using the DI Sort coupling to permit for more substantial bore sizes on most DI coupling sizes. This permits for your use of smaller DI couplings in applications exactly where a smaller size coupling can even now accommodate the application torque.
Industrial SXC Type
The SXC Form will be the shut coupled variation from the SX Kind coupling. The SXC is much like the SX coupling in that the disc packs are connected when the coupling is put in. While in the near coupled units, the hubs are turned inward and are mounted within the spacer. Note that using the hubs inside the spacer, the maximum bore permitted inside the hub will likely be decreased. The SXC couplings can be made use of with 1 or the two hubs turned outward to allow the coupling to accommodate various shaft separations.
Industrial SXCS and SXCST Styles
The SXCS and SXCST Kinds have split spacers and the disc packs can be serviced or eliminated without having moving the hubs around the shafts and with out moving the tools. The SXCS Variety has the bolts that connect the hubs to your split spacer set up through the ends of your couplings. The SXCST possess the bolts installed from inside the spacer pointing outward in the direction of the hubs.
