Disc Coupling Overview

Industrial SU Style
The SU Kind coupling features 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 by using a shaft
to make a floating shaft coupling. The shaft can be hollow for extended light fat floating shaft couplings.
Industrial SX Kind
This can be the regular coupling form that involves two hubs, a stock length spacer intended to meet marketplace typical lengths, and two unitized disc packs. The coupling has two flex planes, 1 at every single disc pack, making it possible for this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is available in six and eight bolt models and bore sizes as much as 13 inches (330mm) to the biggest size. Customized spacer lengths may be manufactured to meet exclusive shaft separations essential for unique applications. The SX coupling is often fitted with overload bushings to guard the disc packs in in excess of torque conditions and will act as an anti-flail gadget. SX couplings are assembled on the time of set up on the equipment in which the coupling are going to be in services.
Industrial DI Style
The DI Sort coupling includes a “Drop-In” spacer assembly that is assembled with the factory. The coupling includes two hubs plus a spacer assembly comprising of your spacer, two unitized disc packs, and two guard rings. The disc packs are bolted to your spacer and guard rings in the factory using the torque values suggested by Lovejoy for your disc pack bolts. Using the hubs mounted within the shafts, the complete disc pack assembly is usually “Dropped In” location in between the two hubs. The hubs are piloted to guarantee suitable centering of the spacer assembly. This piloting serves as an anti-flail function and aids in the coupling’s capability to meet the stability specifications mandated by API. This fashion coupling is designed to meet the balance and anti-flail requirements specified in API-610.
Oversized, or Jumbo, hubs can be found for use with the DI Form coupling to permit for more substantial bore sizes on most DI coupling sizes. This enables for that utilization of smaller sized DI couplings in applications wherever a smaller dimension coupling can nonetheless accommodate the application torque.
Industrial SXC Style
The SXC Variety will be the close coupled variation of your SX Kind coupling. The SXC is similar to the SX coupling in the disc packs are attached when the coupling is installed. In the shut coupled units, the hubs are turned inward and therefore are mounted inside the spacer. Note that with all the hubs within the spacer, the maximum bore permitted in the hub might be decreased. The SXC couplings is often utilized with one or both hubs turned outward to permit the coupling to accommodate various shaft separations.
Industrial SXCS and SXCST Kinds
The SXCS and SXCST Sorts have split spacers and the disc packs might be serviced or eliminated with no moving the hubs to the shafts and without the need of moving the equipment. The SXCS Variety has the bolts that connect the hubs on the split spacer put in through the ends of your couplings. The SXCST have the bolts put in from inside the spacer pointing outward in the direction of the hubs.
