Disc Coupling Overview

Industrial SU Type
The SU Variety coupling includes a single flex plane with two hubs as well as a single disc pack. It is actually suitable for angular and axial misalignment only. Two SU couplings are often combined with a shaft
to produce a floating shaft coupling. The shaft may be hollow for lengthy light bodyweight floating shaft couplings.
Industrial SX Sort
This is certainly the standard coupling kind that contains two hubs, a stock length spacer created to meet sector standard lengths, and two unitized disc packs. The coupling has two flex planes, one at each and every disc pack, enabling this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is available in 6 and eight bolt models and bore sizes as much as 13 inches (330mm) around the largest size. Custom spacer lengths may be produced to meet special shaft separations needed for distinct applications. The SX coupling can be fitted with overload bushings to protect the disc packs in more than torque circumstances and can act as an anti-flail device. SX couplings are assembled on the time of installation to the tools exactly where the coupling will be in services.
Industrial DI Kind
The DI Type coupling features a “Drop-In” spacer assembly that is certainly assembled in the factory. The coupling consists of two hubs and 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 on the factory applying the torque values advised by Lovejoy for that disc pack bolts. Using the hubs mounted over the shafts, the entire disc pack assembly might be “Dropped In” location in between the two hubs. The hubs are piloted to make certain appropriate centering of your spacer assembly. This piloting serves as an anti-flail characteristic and aids from the coupling’s means to meet the stability specifications mandated by API. This fashion coupling is created to meet the stability and anti-flail necessities specified in API-610.
Oversized, or Jumbo, hubs can be found for use using the DI Type 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 sized dimension coupling can nevertheless accommodate the application torque.
Industrial SXC Sort
The SXC Variety will be the close coupled variation from the SX Style coupling. The SXC is much like the SX coupling in that the disc packs are attached when the coupling is set up. Inside the shut coupled units, the hubs are turned inward and are mounted inside the spacer. Note that with all the hubs within the spacer, the maximum bore permitted while in the hub will likely be decreased. The SXC couplings is often made use of with a single or each hubs turned outward to allow the coupling to accommodate different shaft separations.
Industrial SXCS and SXCST Sorts
The SXCS and SXCST Types have split spacers and also the disc packs might be serviced or removed with no moving the hubs around the shafts and with out moving the products. The SXCS Variety has the bolts that connect the hubs for the split spacer set up through the ends with the couplings. The SXCST have the bolts set up from inside the spacer pointing outward towards the hubs.
