Disc Coupling Overview

Industrial SU Style
The SU Kind coupling includes a single flex plane with two hubs along with a single disc pack. It really is appropriate for angular and axial misalignment only. Two SU couplings are frequently combined which has a shaft
to produce a floating shaft coupling. The shaft is often hollow for prolonged light fat floating shaft couplings.
Industrial SX Style
This really is the common coupling form that involves two hubs, a stock length spacer built to meet market regular lengths, and two unitized disc packs. The coupling has two flex planes, one particular at just about every disc pack, enabling this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is obtainable in 6 and 8 bolt models and bore sizes as much as 13 inches (330mm) about the biggest size. Customized spacer lengths may be manufactured to meet specific shaft separations demanded for certain applications. The SX coupling could be fitted with overload bushings to safeguard the disc packs in above torque problems and may act as an anti-flail gadget. SX couplings are assembled in the time of installation over the tools in which the coupling might be in services.
Industrial DI Sort
The DI Form coupling includes a “Drop-In” spacer assembly that is certainly assembled on the factory. The coupling consists of two hubs along with a spacer assembly comprising of your spacer, two unitized disc packs, and two guard rings. The disc packs are bolted to the spacer and guard rings in the factory working with the torque values suggested by Lovejoy for that disc pack bolts. With the hubs mounted about the shafts, the complete disc pack assembly might be “Dropped In” spot among the 2 hubs. The hubs are piloted to be sure proper centering of your spacer assembly. This piloting serves as an anti-flail feature and aids in the coupling’s ability to meet the balance requirements mandated by API. This design coupling is designed to meet the balance and anti-flail specifications 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 permits for your utilization of smaller DI couplings in applications wherever a smaller sized dimension coupling can even now accommodate the application torque.
Industrial SXC Style
The SXC Variety may be the near coupled variation from the SX Form coupling. The SXC is much like the SX coupling in the disc packs are connected once the coupling is put in. Within the shut coupled units, the hubs are turned inward and are mounted inside the spacer. Note that together with the hubs within the spacer, the maximum bore permitted from the hub will be decreased. The SXC couplings may be made use of with one particular or each hubs turned outward to allow the coupling to accommodate distinctive shaft separations.
Industrial SXCS and SXCST Varieties
The SXCS and SXCST Sorts have split spacers as well as disc packs could be serviced or eliminated with no moving the hubs about the shafts and without moving the products. The SXCS Style has the bolts that connect the hubs on the split spacer installed from the ends in the couplings. The SXCST possess the bolts set up from inside the spacer pointing outward in the direction of the hubs.
