Disc Coupling Overview

Industrial SU Variety
The SU Type coupling features a single flex plane with two hubs and a single disc pack. It truly is ideal for angular and axial misalignment only. Two SU couplings tend to be mixed with a shaft
for making a floating shaft coupling. The shaft may be hollow for prolonged light excess weight floating shaft couplings.
Industrial SX Type
This really is the normal coupling sort that contains two hubs, a stock length spacer built to meet business normal 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 obtainable in 6 and eight bolt designs and bore sizes up to 13 inches (330mm) about the greatest dimension. Custom spacer lengths can be manufactured to meet special shaft separations needed for unique applications. The SX coupling can be fitted with overload bushings to protect the disc packs in more than torque disorders and will act as an anti-flail device. SX couplings are assembled at the time of installation over the gear where the coupling is going to be in services.
Industrial DI Kind
The DI Style coupling features a “Drop-In” spacer assembly that’s assembled at the factory. The coupling consists of two hubs as well as a spacer assembly comprising of the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted to the spacer and guard rings with the factory applying the torque values advised by Lovejoy to the disc pack bolts. Together with the hubs mounted within the shafts, the complete disc pack assembly could be “Dropped In” area in between the two hubs. The hubs are piloted to ensure proper centering of the spacer assembly. This piloting serves as an anti-flail function and aids within the coupling’s skill to meet the balance requirements mandated by API. This design coupling is intended to meet the stability and anti-flail specifications specified in API-610.
Oversized, or Jumbo, hubs are available for use with all the DI Form coupling to permit for bigger bore sizes on most DI coupling sizes. This permits to the utilization of smaller DI couplings in applications in which a smaller sized size coupling can even now accommodate the application torque.
Industrial SXC Variety
The SXC Sort may be the near coupled variation in the SX Kind coupling. The SXC is similar to the SX coupling in that the disc packs are connected when the coupling is installed. Within the near coupled units, the hubs are turned inward and are mounted inside the spacer. Note that together with the hubs inside the spacer, the utmost bore permitted while in the hub will probably be decreased. The SXC couplings is often utilised with 1 or each hubs turned outward to permit the coupling to accommodate distinct shaft separations.
Industrial SXCS and SXCST Varieties
The SXCS and SXCST Kinds have split spacers as well as disc packs could be serviced or eliminated without moving the hubs within the shafts and without moving the gear. The SXCS Type has the bolts that connect the hubs towards the split spacer put in in the ends in the couplings. The SXCST have the bolts put in from within the spacer pointing outward towards the hubs.
