Disc Coupling Overview

Industrial SU Type
The SU Type coupling features a single flex plane with two hubs in addition to a single disc pack. It really is appropriate for angular and axial misalignment only. Two SU couplings tend to be mixed that has a shaft
to make a floating shaft coupling. The shaft could be hollow for lengthy light bodyweight floating shaft couplings.
Industrial SX Form
This is certainly the regular coupling variety that incorporates two hubs, a stock length spacer created to meet marketplace common lengths, and two unitized disc packs. The coupling has two flex planes, 1 at each disc pack, allowing this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is available in 6 and 8 bolt models and bore sizes as much as 13 inches (330mm) over the biggest dimension. Customized spacer lengths can be manufactured to meet unique shaft separations required for distinct applications. The SX coupling is often fitted with overload bushings to safeguard the disc packs in more than torque conditions and can act as an anti-flail device. SX couplings are assembled at the time of installation within the tools wherever the coupling will probably be in support.
Industrial DI Form
The DI Kind coupling includes a “Drop-In” spacer assembly that is certainly assembled at the factory. The coupling includes two hubs along with a spacer assembly comprising of your spacer, two unitized disc packs, and two guard rings. The disc packs are bolted to your spacer and guard rings in the factory applying the torque values suggested by Lovejoy for the disc pack bolts. Using the hubs mounted within the shafts, the complete disc pack assembly may be “Dropped In” spot amongst the two hubs. The hubs are piloted to be sure proper centering from the spacer assembly. This piloting serves as an anti-flail characteristic and aids inside the coupling’s skill to meet the balance standards mandated by API. This design coupling is made to meet the balance and anti-flail demands specified in API-610.
Oversized, or Jumbo, hubs can be found for use together with the DI Form coupling to allow for bigger bore sizes on most DI coupling sizes. This enables for your utilization of smaller DI couplings in applications where a smaller dimension coupling can still accommodate the application torque.
Industrial SXC Type
The SXC Sort may be the near coupled variation in the SX Style coupling. The SXC is similar to the SX coupling in that the disc packs are connected when the coupling is set up. From the near coupled units, the hubs are turned inward and are mounted within the spacer. Note that with all the hubs inside the spacer, the utmost bore allowed in the hub is going to be decreased. The SXC couplings is often made use of with a single or the two hubs turned outward to allow the coupling to accommodate distinctive shaft separations.
Industrial SXCS and SXCST Kinds
The SXCS and SXCST Forms have split spacers and also the disc packs might be serviced or removed devoid of moving the hubs within the shafts and without the need of moving the tools. The SXCS Form has the bolts that connect the hubs to your split spacer put in from the ends in the couplings. The SXCST possess the bolts put in from within the spacer pointing outward in direction of the hubs.
