Disc Coupling Overview

Industrial SU Kind
The SU Kind coupling has a single flex plane with two hubs plus a single disc pack. It’s ideal for angular and axial misalignment only. Two SU couplings are frequently combined with a shaft
to produce a floating shaft coupling. The shaft could be hollow for long light excess weight floating shaft couplings.
Industrial SX Variety
This really is the regular coupling type that includes two hubs, a stock length spacer made to meet marketplace standard lengths, and two unitized disc packs. The coupling has two flex planes, a single at just about every disc pack, enabling this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is obtainable in 6 and eight bolt styles and bore sizes up to 13 inches (330mm) around the biggest size. Customized spacer lengths might be produced to meet distinctive shaft separations demanded for specific applications. The SX coupling could be fitted with overload bushings to guard the disc packs in in excess of torque disorders and can act as an anti-flail device. SX couplings are assembled at the time of set up over the tools the place the coupling will be in service.
Industrial DI Type
The DI Variety coupling features a “Drop-In” spacer assembly that is certainly assembled on the factory. The coupling includes two hubs as well as a spacer assembly comprising from the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted towards the spacer and guard rings with the factory making use of the torque values suggested by Lovejoy for your disc pack bolts. With all the hubs mounted about the shafts, the whole disc pack assembly is usually “Dropped In” location between the 2 hubs. The hubs are piloted to be sure appropriate centering of your spacer assembly. This piloting serves as an anti-flail characteristic and aids while in the coupling’s skill to meet the stability requirements mandated by API. This design coupling is created to meet the balance and anti-flail demands specified in API-610.
Oversized, or Jumbo, hubs are available for use using the DI Variety coupling to allow for greater bore sizes on most DI coupling sizes. This allows for your utilization of smaller sized DI couplings in applications the place a smaller dimension coupling can even now accommodate the application torque.
Industrial SXC Kind
The SXC Variety is the close coupled variation of the SX Sort coupling. The SXC is much like the SX coupling in the disc packs are attached when the coupling is set up. While in the near 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 in the hub might be decreased. The SXC couplings is usually made use of with one particular or the two hubs turned outward to permit the coupling to accommodate diverse shaft separations.
Industrial SXCS and SXCST Forms
The SXCS and SXCST Kinds have split spacers along with the disc packs could be serviced or eliminated without the need of moving the hubs over the shafts and devoid of moving the gear. The SXCS Variety has the bolts that connect the hubs for the split spacer installed from your ends with the couplings. The SXCST have the bolts put in from within the spacer pointing outward towards the hubs.
