Industrial SU Form
The SU Kind coupling includes a single flex plane with two hubs as well as a single disc pack. It is suitable for angular and axial misalignment only. Two SU couplings are sometimes combined with a shaft
for making a floating shaft coupling. The shaft can be hollow for lengthy light fat floating shaft couplings.
Industrial SX Style
This is certainly the normal coupling style that contains two hubs, a stock length spacer made to meet field common lengths, and two unitized disc packs. The coupling has two flex planes, one particular at every single disc pack, enabling this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is available in six and eight bolt models and bore sizes up to 13 inches (330mm) on the biggest dimension. Custom spacer lengths might be manufactured to meet exclusive shaft separations expected for specific applications. The SX coupling could be fitted with overload bushings to guard the disc packs in above torque disorders and will act as an anti-flail device. SX couplings are assembled on the time of set up within the tools the place the coupling will likely be in service.
Industrial DI Kind
The DI Kind coupling has a “Drop-In” spacer assembly that’s assembled with the factory. The coupling includes two hubs and a spacer assembly comprising on the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted to your spacer and guard rings with the factory using the torque values suggested by Lovejoy for your disc pack bolts. With the hubs mounted about the shafts, the complete disc pack assembly is often “Dropped In” location between the two hubs. The hubs are piloted to make certain proper centering of the spacer assembly. This piloting serves as an anti-flail function and aids while in the coupling’s ability to meet the balance standards mandated by API. This type coupling is developed to meet the stability and anti-flail necessities specified in API-610.
Oversized, or Jumbo, hubs are available for use together with the DI Kind coupling to permit for larger bore sizes on most DI coupling sizes. This enables for the use of smaller DI couplings in applications in which a smaller dimension coupling can nonetheless accommodate the application torque.
Industrial SXC Form
The SXC Variety would be the shut coupled variation of the SX Sort coupling. The SXC is just like the SX coupling in the disc packs are connected when the coupling is installed. While in the shut coupled units, the hubs are turned inward and are mounted within the spacer. Note that together with the hubs within the spacer, the utmost bore allowed while in the hub is going to be decreased. The SXC couplings might be utilised with one or both hubs turned outward to allow the coupling to accommodate distinctive shaft separations.
Industrial SXCS and SXCST Types
The SXCS and SXCST Types have split spacers as well as the disc packs might be serviced or eliminated without having moving the hubs over the shafts and with out moving the equipment. The SXCS Form has the bolts that connect the hubs towards the split spacer set up through the ends in the couplings. The SXCST have the bolts put in from within the spacer pointing outward in the direction of the hubs.
