Industrial SU Style
The SU Sort coupling features a single flex plane with two hubs and also a single disc pack. It’s appropriate for angular and axial misalignment only. Two SU couplings tend to be mixed which has a shaft
for making a floating shaft coupling. The shaft is often hollow for lengthy light bodyweight floating shaft couplings.
Industrial SX Sort
This is the typical coupling form that includes two hubs, a stock length spacer intended to meet marketplace standard lengths, and two unitized disc packs. The coupling has two flex planes, one at every single disc pack, making it possible for this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is accessible in 6 and eight bolt designs and bore sizes up to 13 inches (330mm) over the largest dimension. Custom spacer lengths is often manufactured to meet exclusive shaft separations demanded for precise applications. The SX coupling can be fitted with overload bushings to safeguard the disc packs in more than torque disorders and can act as an anti-flail device. SX couplings are assembled at the time of installation to the equipment where the coupling will probably be in services.
Industrial DI Style
The DI Form coupling has a “Drop-In” spacer assembly which is assembled with the factory. The coupling consists of two hubs as well as a spacer assembly comprising on the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted for the spacer and guard rings at the factory applying the torque values proposed by Lovejoy for that disc pack bolts. With the hubs mounted to the shafts, the complete disc pack assembly is usually “Dropped In” location involving the 2 hubs. The hubs are piloted to ensure good centering of your spacer assembly. This piloting serves as an anti-flail attribute and aids within the coupling’s means to meet the balance requirements mandated by API. This style coupling is built to meet the balance and anti-flail requirements specified in API-610.
Oversized, or Jumbo, hubs can be found for use with the DI Sort coupling to allow for larger bore sizes on most DI coupling sizes. This permits for that use of smaller DI couplings in applications the place a smaller dimension coupling can still accommodate the application torque.
Industrial SXC Form
The SXC Type will be the close coupled variation of your SX Style coupling. The SXC is similar to the SX coupling in that the disc packs are connected 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 the hubs within the spacer, the utmost bore permitted in the hub might be decreased. The SXC couplings could be applied with 1 or each hubs turned outward to permit the coupling to accommodate distinctive shaft separations.
Industrial SXCS and SXCST Forms
The SXCS and SXCST Varieties have split spacers and also the disc packs may be serviced or removed with out moving the hubs on the shafts and without the need of moving the equipment. The SXCS Variety has the bolts that connect the hubs to the split spacer put in from the ends from the couplings. The SXCST have the bolts installed from within the spacer pointing outward towards the hubs.
