Disc Coupling Overview

Industrial SU Style
The SU Style coupling features a single flex plane with two hubs and also a single disc pack. It is suitable for angular and axial misalignment only. Two SU couplings are often mixed by using a shaft
to produce a floating shaft coupling. The shaft might be hollow for extended light excess weight floating shaft couplings.
Industrial SX Sort
That is the conventional coupling sort that contains two hubs, a stock length spacer intended to meet sector common lengths, and two unitized disc packs. The coupling has two flex planes, 1 at just about every disc pack, permitting this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is available in 6 and eight bolt patterns and bore sizes as much as 13 inches (330mm) about the biggest dimension. Customized spacer lengths might be produced to meet particular shaft separations necessary for unique applications. The SX coupling can be fitted with overload bushings to protect the disc packs in in excess of torque circumstances and will act as an anti-flail device. SX couplings are assembled on the time of set up about the tools in which the coupling might be in support.
Industrial DI Kind
The DI Style coupling has a “Drop-In” spacer assembly that’s assembled at the factory. The coupling consists of two hubs and also a spacer assembly comprising with the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted to the spacer and guard rings at the factory utilizing the torque values encouraged by Lovejoy for your disc pack bolts. Together with the hubs mounted around the shafts, the complete disc pack assembly can be “Dropped In” location amongst the two hubs. The hubs are piloted to guarantee good centering of your spacer assembly. This piloting serves as an anti-flail attribute and aids during the coupling’s potential to meet the stability requirements mandated by API. This style coupling is intended to meet the balance and anti-flail necessities specified in API-610.
Oversized, or Jumbo, hubs can be found for use together with the DI Form coupling to allow for more substantial bore sizes on most DI coupling sizes. This enables for the utilization of smaller sized DI couplings in applications where a smaller sized dimension coupling can still accommodate the application torque.
Industrial SXC Kind
The SXC Style is definitely the shut coupled variation in the SX Style coupling. The SXC is much like the SX coupling in the disc packs are connected once the coupling is put in. While in the shut coupled units, the hubs are turned inward and are mounted within the spacer. Note that together with the hubs within the spacer, the maximum bore allowed while in the hub are going to be decreased. The SXC couplings could be utilised with 1 or each hubs turned outward to permit the coupling to accommodate different shaft separations.
Industrial SXCS and SXCST Varieties
The SXCS and SXCST Varieties have split spacers along with the disc packs is often serviced or eliminated with out moving the hubs about the shafts and without the need of moving the gear. The SXCS Form has the bolts that connect the hubs for the split spacer set up through the ends from the couplings. The SXCST have the bolts installed from inside the spacer pointing outward in direction of the hubs.
