Industrial SU Variety
The SU Sort coupling features a single flex plane with two hubs and a single disc pack. It is suitable for angular and axial misalignment only. Two SU couplings are sometimes combined with a shaft
to produce a floating shaft coupling. The shaft could be hollow for extended light excess weight floating shaft couplings.
Industrial SX Style
This is the standard coupling form that consists of two hubs, a stock length spacer created to meet marketplace normal lengths, and two unitized disc packs. The coupling has two flex planes, 1 at every single disc pack, enabling this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is available in six and 8 bolt designs and bore sizes as much as 13 inches (330mm) to the greatest dimension. Customized spacer lengths might be produced to meet unique shaft separations expected for particular applications. The SX coupling might be fitted with overload bushings to guard the disc packs in in excess of torque situations and will act as an anti-flail gadget. SX couplings are assembled with the time of set up to the equipment exactly where the coupling is going to be in support.
Industrial DI Form
The DI Type coupling features a “Drop-In” spacer assembly which is assembled with the factory. The coupling includes two hubs plus a spacer assembly comprising with the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted to the spacer and guard rings at the factory using the torque values advisable by Lovejoy to the disc pack bolts. With all the hubs mounted about the shafts, the whole disc pack assembly could be “Dropped In” location amongst the 2 hubs. The hubs are piloted to make certain appropriate centering with the spacer assembly. This piloting serves as an anti-flail characteristic and aids while in the coupling’s capacity to meet the stability requirements mandated by API. This style coupling is designed to meet the stability and anti-flail needs specified in API-610.
Oversized, or Jumbo, hubs can be found for use with all the DI Sort coupling to permit for more substantial bore sizes on most DI coupling sizes. This enables to the use of smaller DI couplings in applications wherever a smaller size coupling can even now accommodate the application torque.
Industrial SXC Kind
The SXC Form will be the near coupled variation of your SX Variety coupling. The SXC is much like the SX coupling in that the disc packs are connected once the coupling is installed. During the close coupled units, the hubs are turned inward and are mounted inside the spacer. Note that using the hubs within the spacer, the utmost bore allowed in the hub will probably be decreased. The SXC couplings is often employed with one particular or both hubs turned outward to permit the coupling to accommodate different shaft separations.
Industrial SXCS and SXCST Varieties
The SXCS and SXCST Sorts have split spacers as well as the disc packs is usually serviced or eliminated without the need of moving the hubs over the shafts and without the need of moving the tools. The SXCS Variety has the bolts that connect the hubs on the split spacer installed through the ends in the couplings. The SXCST possess the bolts put in from within the spacer pointing outward in direction of the hubs.
