Industrial SU Style
The SU Style coupling features a single flex plane with two hubs and also a single disc pack. It’s suitable for angular and axial misalignment only. Two SU couplings are sometimes mixed having a shaft
to generate a floating shaft coupling. The shaft can be hollow for extended light weight floating shaft couplings.
Industrial SX Variety
This is the common coupling form that involves two hubs, a stock length spacer built to meet sector standard lengths, and two unitized disc packs. The coupling has two flex planes, one particular at just about every disc pack, allowing this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is available in 6 and eight bolt models and bore sizes up to 13 inches (330mm) on the largest dimension. Customized spacer lengths can be manufactured to meet exclusive shaft separations demanded for particular applications. The SX coupling could be fitted with overload bushings to protect the disc packs in in excess of torque ailments and will act as an anti-flail gadget. SX couplings are assembled with the time of set up to the products where the coupling is going to be in services.
Industrial DI Style
The DI Form 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 from the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted to your spacer and guard rings on the factory using the torque values proposed by Lovejoy to the disc pack bolts. Together with the hubs mounted around the shafts, the complete disc pack assembly is usually “Dropped In” spot amongst the two hubs. The hubs are piloted to make sure suitable centering of the spacer assembly. This piloting serves as an anti-flail function and aids in the coupling’s potential to meet the stability standards mandated by API. This type coupling is intended to meet the stability and anti-flail requirements specified in API-610.
Oversized, or Jumbo, hubs can be found for use using the DI Type coupling to allow for bigger bore sizes on most DI coupling sizes. This enables to the utilization of smaller sized DI couplings in applications exactly where a smaller dimension coupling can even now accommodate the application torque.
Industrial SXC Variety
The SXC Kind may be the close coupled variation from the SX Variety coupling. The SXC is just like the SX coupling in the disc packs are attached when the coupling is installed. In the close coupled units, the hubs are turned inward and therefore are mounted within the spacer. Note that together with the hubs inside the spacer, the utmost bore permitted in the hub will be decreased. The SXC couplings can be made use of with 1 or both hubs turned outward to permit the coupling to accommodate various shaft separations.
Industrial SXCS and SXCST Kinds
The SXCS and SXCST Styles have split spacers as well as the disc packs may be serviced or removed with out moving the hubs within the shafts and without moving the equipment. The SXCS Style has the bolts that connect the hubs on the split spacer installed from your ends of your couplings. The SXCST have the bolts put in from inside the spacer pointing outward in direction of the hubs.
