Disc Coupling Overview

Industrial SU Variety
The SU Sort coupling has a single flex plane with two hubs as well as a single disc pack. It can be suitable for angular and axial misalignment only. Two SU couplings tend to be combined with a shaft
to generate a floating shaft coupling. The shaft is usually hollow for prolonged light fat floating shaft couplings.
Industrial SX Type
This is certainly the common coupling form that consists of two hubs, a stock length spacer made to meet sector conventional lengths, and two unitized disc packs. The coupling has two flex planes, one particular at just about every 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 8 bolt designs and bore sizes as much as 13 inches (330mm) over the largest dimension. Customized spacer lengths can be manufactured to meet exclusive shaft separations demanded for precise applications. The SX coupling could be fitted with overload bushings to protect the disc packs in more than torque situations and will act as an anti-flail gadget. SX couplings are assembled with the time of set up to the equipment the place the coupling are going to be in support.
Industrial DI Kind
The DI Type coupling features a “Drop-In” spacer assembly that is assembled in the factory. The coupling consists of two hubs along with a spacer assembly comprising in the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted to your spacer and guard rings at the factory making use of the torque values suggested by Lovejoy for your disc pack bolts. Together with the hubs mounted to the shafts, the whole disc pack assembly could be “Dropped In” place among the 2 hubs. The hubs are piloted to be sure appropriate centering of the spacer assembly. This piloting serves as an anti-flail function and aids within the coupling’s capability to meet the balance specifications mandated by API. This type coupling is designed to meet the stability and anti-flail prerequisites specified in API-610.
Oversized, or Jumbo, hubs can be found for use with the DI Kind coupling to allow for larger bore sizes on most DI coupling sizes. This enables for that utilization of smaller DI couplings in applications where a smaller dimension coupling can still accommodate the application torque.
Industrial SXC Kind
The SXC Sort may be the close coupled variation from the SX Form coupling. The SXC is just like the SX coupling in that the disc packs are attached once the coupling is installed. While in the close coupled units, the hubs are turned inward and therefore are mounted inside the spacer. Note that with all the hubs inside the spacer, the maximum bore allowed while in the hub will probably be decreased. The SXC couplings might be utilized with a single or each hubs turned outward to permit the coupling to accommodate unique shaft separations.
Industrial SXCS and SXCST Types
The SXCS and SXCST Varieties have split spacers along with the disc packs might be serviced or eliminated with out moving the hubs on the shafts and devoid of moving the tools. The SXCS Sort has the bolts that connect the hubs for the split spacer put in through the ends with the couplings. The SXCST have the bolts installed from inside the spacer pointing outward towards the hubs.
