Disc Coupling Overview

Industrial SU Type
The SU Variety coupling has a single flex plane with two hubs along with a single disc pack. It is appropriate for angular and axial misalignment only. Two SU couplings are often mixed having a shaft
to produce a floating shaft coupling. The shaft might be hollow for extended light bodyweight floating shaft couplings.
Industrial SX Type
This can be the normal coupling variety that involves two hubs, a stock length spacer designed to meet industry common lengths, and two unitized disc packs. The coupling has two flex planes, a single at every disc pack, permitting this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is obtainable in six and eight bolt styles and bore sizes up to 13 inches (330mm) around the largest size. Custom spacer lengths can be manufactured to meet specific shaft separations required for specific applications. The SX coupling could be fitted with overload bushings to protect the disc packs in more than torque conditions and might act as an anti-flail device. SX couplings are assembled with the time of set up within the equipment in which the coupling will likely be in service.
Industrial DI Sort
The DI Variety coupling has a “Drop-In” spacer assembly that’s assembled at the factory. The coupling consists of two hubs plus a spacer assembly comprising with the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted to your spacer and guard rings on the factory applying the torque values advisable by Lovejoy for that disc pack bolts. Using the hubs mounted about the shafts, the entire disc pack assembly may be “Dropped In” place amongst the two hubs. The hubs are piloted to guarantee suitable centering with the spacer assembly. This piloting serves as an anti-flail attribute and aids from the coupling’s ability to meet the balance requirements mandated by API. This type coupling is intended to meet the balance and anti-flail needs specified in API-610.
Oversized, or Jumbo, hubs are available for use with all the DI Style coupling to permit for greater bore sizes on most DI coupling sizes. This allows for the use of smaller sized DI couplings in applications in which a smaller sized dimension coupling can nevertheless accommodate the application torque.
Industrial SXC Sort
The SXC Kind may be the shut coupled variation in the SX Kind coupling. The SXC is much like the SX coupling in the disc packs are connected when the coupling is put in. Inside the close coupled units, the hubs are turned inward and therefore are mounted within the spacer. Note that using the hubs within the spacer, the utmost bore allowed from the hub are going to be decreased. The SXC couplings might be utilised with 1 or both hubs turned outward to permit the coupling to accommodate different shaft separations.
Industrial SXCS and SXCST Kinds
The SXCS and SXCST Sorts have split spacers and also the disc packs might be serviced or removed without having moving the hubs over the shafts and with no moving the tools. The SXCS Sort has the bolts that connect the hubs to your split spacer put in from the ends on the couplings. The SXCST have the bolts installed from inside the spacer pointing outward in the direction of the hubs.
