Disc Coupling Overview

Industrial SU Sort
The SU Variety coupling has a single flex plane with two hubs along with a single disc pack. It is ideal for angular and axial misalignment only. Two SU couplings tend to be mixed which has a shaft
to create a floating shaft coupling. The shaft is usually hollow for long light fat floating shaft couplings.
Industrial SX Type
That is the regular coupling kind that includes two hubs, a stock length spacer created to meet market conventional 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 obtainable in 6 and 8 bolt styles and bore sizes as much as 13 inches (330mm) to the largest size. Custom spacer lengths might be produced to meet unique shaft separations expected for specific applications. The SX coupling is usually fitted with overload bushings to safeguard the disc packs in more than torque problems and might act as an anti-flail gadget. SX couplings are assembled on the time of installation around the gear wherever the coupling will probably be in service.
Industrial DI Sort
The DI Variety coupling features a “Drop-In” spacer assembly which is assembled with the factory. The coupling consists of two hubs and a spacer assembly comprising with the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted for the spacer and guard rings in the factory applying the torque values advised by Lovejoy for your disc pack bolts. With all the hubs mounted over the shafts, the whole disc pack assembly might be “Dropped In” location between the 2 hubs. The hubs are piloted to ensure proper centering on the spacer assembly. This piloting serves as an anti-flail feature and aids while in the coupling’s capability to meet the balance specifications mandated by API. This fashion coupling is made to meet the balance and anti-flail necessities specified in API-610.
Oversized, or Jumbo, hubs can be found for use with the DI Variety coupling to allow for more substantial bore sizes on most DI coupling sizes. This permits for the use of smaller sized DI couplings in applications where a smaller sized size coupling can nevertheless accommodate the application torque.
Industrial SXC Sort
The SXC Style is the near coupled variation of the SX Type coupling. The SXC is similar to the SX coupling in that the disc packs are connected once the coupling is put in. During the shut coupled units, the hubs are turned inward and are mounted within the spacer. Note that with all the hubs inside the spacer, the maximum bore allowed from the hub are going to be decreased. The SXC couplings is usually applied with one or each hubs turned outward to allow the coupling to accommodate different shaft separations.
Industrial SXCS and SXCST Forms
The SXCS and SXCST Forms have split spacers and the disc packs is often serviced or eliminated without moving the hubs over the shafts and devoid of moving the products. The SXCS Sort has the bolts that connect the hubs for the split spacer put in from the ends in the couplings. The SXCST possess the bolts installed from within the spacer pointing outward towards the hubs.
