Disc Coupling Overview

Industrial SU Kind
The SU Variety 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 having a shaft
for making a floating shaft coupling. The shaft can be hollow for long light weight floating shaft couplings.
Industrial SX Sort
This is certainly the standard coupling type that includes two hubs, a stock length spacer created to meet marketplace typical lengths, and two unitized disc packs. The coupling has two flex planes, 1 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 6 and eight bolt styles and bore sizes as much as 13 inches (330mm) over the greatest dimension. Customized spacer lengths is often produced to meet distinctive shaft separations needed for precise applications. The SX coupling is often fitted with overload bushings to protect the disc packs in in excess of torque disorders and will act as an anti-flail device. SX couplings are assembled with the time of installation within the equipment wherever the coupling will probably be in service.
Industrial DI Style
The DI Type coupling has a “Drop-In” spacer assembly that may be assembled with the factory. The coupling includes two hubs and also a spacer assembly comprising from the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted for the spacer and guard rings on the factory utilizing the torque values advisable by Lovejoy for the disc pack bolts. With all the hubs mounted over the shafts, the entire disc pack assembly is usually “Dropped In” area involving the two hubs. The hubs are piloted to ensure suitable centering from the spacer assembly. This piloting serves as an anti-flail function and aids while in the coupling’s capacity to meet the stability standards mandated by API. This style coupling is created to meet the balance and anti-flail necessities specified in API-610.
Oversized, or Jumbo, hubs are available for use together with the DI Kind coupling to permit for bigger bore sizes on most DI coupling sizes. This enables for that utilization of smaller sized DI couplings in applications exactly where a smaller size coupling can still accommodate the application torque.
Industrial SXC Kind
The SXC Type is definitely the close coupled variation on the SX Type coupling. The SXC is just like the SX coupling in that the disc packs are attached when the coupling is installed. While in the close coupled units, the hubs are turned inward and therefore are mounted inside the spacer. Note that using the hubs inside the spacer, the utmost bore allowed in the hub will likely be decreased. The SXC couplings might be utilized with 1 or both hubs turned outward to permit the coupling to accommodate various shaft separations.
Industrial SXCS and SXCST Forms
The SXCS and SXCST Styles have split spacers and also the disc packs is usually serviced or removed without the need of moving the hubs on the shafts and with no moving the gear. The SXCS Kind has the bolts that connect the hubs to the split spacer set up in the ends of your couplings. The SXCST have the bolts put in from within the spacer pointing outward in direction of the hubs.
