Disc Coupling Overview

Industrial SU Variety
The SU Variety coupling features a single flex plane with two hubs in addition to a single disc pack. It really is suitable for angular and axial misalignment only. Two SU couplings are often mixed using a shaft
for making a floating shaft coupling. The shaft is often hollow for extended light fat floating shaft couplings.
Industrial SX Style
That is the common coupling sort that consists of two hubs, a stock length spacer built to meet industry regular lengths, and two unitized disc packs. The coupling has two flex planes, one particular at every disc pack, making it possible for this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is available in six and eight bolt types and bore sizes as much as 13 inches (330mm) within the greatest dimension. Custom spacer lengths is usually manufactured to meet unique shaft separations required for certain applications. The SX coupling is often fitted with overload bushings to safeguard the disc packs in over torque conditions and may act as an anti-flail gadget. SX couplings are assembled in the time of set up around the products where the coupling will likely be in services.
Industrial DI Sort
The DI Style coupling includes a “Drop-In” spacer assembly that may be assembled with the factory. The coupling includes two hubs and also a spacer assembly comprising on the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted on the spacer and guard rings in the factory working with the torque values advised by Lovejoy for that disc pack bolts. Together with the hubs mounted over the shafts, the complete disc pack assembly may be “Dropped In” area among the two hubs. The hubs are piloted to ensure right centering from the spacer assembly. This piloting serves as an anti-flail feature and aids from the coupling’s ability to meet the balance specifications mandated by API. This type coupling is intended to meet the balance and anti-flail prerequisites specified in API-610.
Oversized, or Jumbo, hubs are available for use with all the DI Style coupling to permit for more substantial bore sizes on most DI coupling sizes. This enables to the use of smaller sized DI couplings in applications wherever a smaller sized size coupling can still accommodate the application torque.
Industrial SXC Variety
The SXC Style may be the near coupled variation in the SX Form coupling. The SXC is just like the SX coupling in that the disc packs are attached when the coupling is set up. During the shut coupled units, the hubs are turned inward and are mounted within the spacer. Note that together with the hubs inside the spacer, the utmost bore permitted inside the hub will be decreased. The SXC couplings may be utilized with one or both hubs turned outward to permit the coupling to accommodate distinctive shaft separations.
Industrial SXCS and SXCST Styles
The SXCS and SXCST Sorts have split spacers plus the disc packs is often serviced or removed with out moving the hubs around the shafts and without moving the tools. The SXCS Style has the bolts that connect the hubs on the split spacer set up from the ends of the couplings. The SXCST possess the bolts installed from inside the spacer pointing outward in the direction of the hubs.
