Disc Coupling Overview

Industrial SU Type
The SU Kind coupling includes a single flex plane with two hubs and a single disc pack. It really is suitable for angular and axial misalignment only. Two SU couplings are often mixed which has a shaft
for making a floating shaft coupling. The shaft is usually hollow for prolonged light bodyweight floating shaft couplings.
Industrial SX Variety
This is certainly the regular coupling variety that contains two hubs, a stock length spacer intended to meet field conventional lengths, and two unitized disc packs. The coupling has two flex planes, one particular at 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 types and bore sizes up to 13 inches (330mm) to the greatest size. Custom spacer lengths is often produced to meet exclusive shaft separations necessary for unique applications. The SX coupling could be fitted with overload bushings to guard the disc packs in in excess of torque problems and will act as an anti-flail gadget. SX couplings are assembled on the time of installation to the products wherever the coupling will be in service.
Industrial DI Variety
The DI Style coupling features a “Drop-In” spacer assembly that’s assembled at the factory. The coupling consists of two hubs and also a spacer assembly comprising of the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted for the spacer and guard rings at the factory making use of the torque values proposed by Lovejoy for that disc pack bolts. Using the hubs mounted within the shafts, the complete disc pack assembly could be “Dropped In” location amongst the two hubs. The hubs are piloted to ensure correct centering from the spacer assembly. This piloting serves as an anti-flail feature and aids within the coupling’s skill to meet the stability standards mandated by API. This design coupling is built to meet the stability and anti-flail requirements specified in API-610.
Oversized, or Jumbo, hubs are available for use using the DI Type coupling to permit for more substantial bore sizes on most DI coupling sizes. This permits for your use of smaller DI couplings in applications in which a smaller size coupling can nonetheless accommodate the application torque.
Industrial SXC Sort
The SXC Type will be the shut coupled variation with the SX Kind coupling. The SXC is much like the SX coupling in the disc packs are attached once the coupling is installed. From the close coupled units, the hubs are turned inward and therefore are mounted inside the spacer. Note that with the hubs inside the spacer, the maximum bore allowed while in the hub will probably be decreased. The SXC couplings could be utilised with a single or the two hubs turned outward to allow the coupling to accommodate distinct shaft separations.
Industrial SXCS and SXCST Sorts
The SXCS and SXCST Sorts have split spacers plus the disc packs may be serviced or removed with no moving the hubs to the shafts and with out moving the gear. The SXCS Form has the bolts that connect the hubs to your split spacer put in in the ends from the couplings. The SXCST have the bolts installed from inside the spacer pointing outward towards the hubs.
