Disc Coupling Overview

Industrial SU Sort
The SU Form coupling has a single flex plane with two hubs and also a single disc pack. It is actually ideal for angular and axial misalignment only. Two SU couplings are often mixed using a shaft
to make a floating shaft coupling. The shaft may be hollow for lengthy light excess weight floating shaft couplings.
Industrial SX Sort
This is certainly the standard coupling kind that consists of two hubs, a stock length spacer created to meet field typical lengths, and two unitized disc packs. The coupling has two flex planes, 1 at each and every disc pack, allowing this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is available in six and eight bolt patterns and bore sizes up to 13 inches (330mm) on the largest dimension. Custom spacer lengths is often produced to meet special shaft separations necessary for unique applications. The SX coupling is usually fitted with overload bushings to protect the disc packs in over torque conditions and will act as an anti-flail device. SX couplings are assembled with the time of set up within the equipment wherever the coupling will probably be in service.
Industrial DI Style
The DI Kind coupling features a “Drop-In” spacer assembly that is assembled at the factory. The coupling includes two hubs and also a spacer assembly comprising in the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted for the spacer and guard rings with the factory utilizing the torque values encouraged by Lovejoy for your disc pack bolts. With all the hubs mounted on the shafts, the entire disc pack assembly can be “Dropped In” place concerning the two hubs. The hubs are piloted to make sure suitable centering in the spacer assembly. This piloting serves as an anti-flail characteristic and aids while in the coupling’s potential to meet the stability standards mandated by API. This style coupling is made to meet the stability and anti-flail necessities specified in API-610.
Oversized, or Jumbo, hubs are available for use together with the DI Sort coupling to permit for bigger bore sizes on most DI coupling sizes. This enables for that use of smaller sized DI couplings in applications in which a smaller size coupling can nonetheless accommodate the application torque.
Industrial SXC Sort
The SXC Type is definitely the close coupled variation with the SX Kind coupling. The SXC is just like the SX coupling in that the disc packs are attached when the coupling is installed. From the close coupled units, the hubs are turned inward and therefore are mounted within the spacer. Note that using the hubs inside the spacer, the utmost bore allowed within the hub is going to be decreased. The SXC couplings is often employed with 1 or both hubs turned outward to permit the coupling to accommodate distinct shaft separations.
Industrial SXCS and SXCST Styles
The SXCS and SXCST Types have split spacers as well as the disc packs is usually serviced or removed without moving the hubs on the shafts and with no moving the gear. The SXCS Sort has the bolts that connect the hubs towards the split spacer set up from your ends of your couplings. The SXCST have the bolts put in from within the spacer pointing outward in direction of the hubs.
