Disc Coupling Overview

Industrial SU Kind
The SU Form coupling features a single flex plane with two hubs as well as a single disc pack. It’s appropriate for angular and axial misalignment only. Two SU couplings tend to be combined by using a shaft
to generate a floating shaft coupling. The shaft could be hollow for lengthy light weight floating shaft couplings.
Industrial SX Style
This can be the typical coupling type that consists of two hubs, a stock length spacer built to meet business standard lengths, and two unitized disc packs. The coupling has two flex planes, one at every single disc pack, permitting this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is accessible in 6 and eight bolt patterns and bore sizes as much as 13 inches (330mm) within the greatest dimension. Customized spacer lengths can be manufactured to meet particular shaft separations demanded for unique applications. The SX coupling can be fitted with overload bushings to protect the disc packs in over torque ailments and can act as an anti-flail device. SX couplings are assembled with the time of installation on the products in which the coupling is going to be in services.
Industrial DI Variety
The DI Form coupling features a “Drop-In” spacer assembly that’s assembled in the factory. The coupling consists of two hubs along with 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 working with the torque values advisable by Lovejoy for that disc pack bolts. Using the hubs mounted on the shafts, the complete disc pack assembly could be “Dropped In” spot concerning the two hubs. The hubs are piloted to make certain right centering of the spacer assembly. This piloting serves as an anti-flail function and aids from the coupling’s capacity to meet the balance specifications mandated by API. This style coupling is designed to meet the stability and anti-flail specifications specified in API-610.
Oversized, or Jumbo, hubs can be found for use using the DI Sort coupling to permit for bigger bore sizes on most DI coupling sizes. This enables to the utilization of smaller sized DI couplings in applications exactly where a smaller sized size coupling can still accommodate the application torque.
Industrial SXC Style
The SXC Kind may be the shut coupled variation from the SX Style coupling. The SXC is similar to the SX coupling in the disc packs are attached when the coupling is installed. From the close coupled units, the hubs are turned inward and are mounted inside the spacer. Note that with the hubs within the spacer, the utmost bore permitted during the hub will be decreased. The SXC couplings could be utilised with a single or both hubs turned outward to permit the coupling to accommodate diverse shaft separations.
Industrial SXCS and SXCST Styles
The SXCS and SXCST Styles have split spacers as well as disc packs is often serviced or removed with no moving the hubs within the shafts and without moving the products. The SXCS Style has the bolts that connect the hubs towards the split spacer put in through the ends of the couplings. The SXCST have the bolts put in from inside the spacer pointing outward in the direction of the hubs.
