Industrial SU Variety
The SU Kind coupling includes a single flex plane with two hubs and a single disc pack. It is suitable for angular and axial misalignment only. Two SU couplings are often mixed that has a shaft
for making a floating shaft coupling. The shaft could be hollow for extended light bodyweight floating shaft couplings.
Industrial SX Type
This is the standard coupling style that contains two hubs, a stock length spacer intended to meet sector regular lengths, and two unitized disc packs. The coupling has two flex planes, one particular at each disc pack, permitting this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is obtainable in 6 and 8 bolt styles and bore sizes as much as 13 inches (330mm) around the biggest dimension. Custom spacer lengths could be produced to meet special shaft separations essential for specific applications. The SX coupling might 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 in the time of installation within the equipment exactly where the coupling will likely be in services.
Industrial DI Variety
The DI Style coupling has a “Drop-In” spacer assembly which is assembled in the factory. The coupling includes two hubs and a spacer assembly comprising of your spacer, two unitized disc packs, and two guard rings. The disc packs are bolted for the spacer and guard rings on the factory utilizing the torque values suggested by Lovejoy to the disc pack bolts. Together with the hubs mounted about the shafts, the entire disc pack assembly can be “Dropped In” place between the two hubs. The hubs are piloted to guarantee proper centering from the spacer assembly. This piloting serves as an anti-flail characteristic and aids in the coupling’s ability to meet the balance standards mandated by API. This style coupling is designed to meet the stability and anti-flail requirements specified in API-610.
Oversized, or Jumbo, hubs can be found for use with all the DI Kind coupling to allow for bigger bore sizes on most DI coupling sizes. This allows for the use 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 Variety is definitely the near coupled variation with the SX Sort coupling. The SXC is just like the SX coupling in that the disc packs are attached when the coupling is installed. In the near coupled units, the hubs are turned inward and are mounted within the spacer. Note that using the hubs within the spacer, the utmost bore permitted during the hub will probably be decreased. The SXC couplings may be applied with a single or the two hubs turned outward to allow the coupling to accommodate different shaft separations.
Industrial SXCS and SXCST Sorts
The SXCS and SXCST Styles have split spacers along with the disc packs might be serviced or removed without moving the hubs over the shafts and with no moving the gear. The SXCS Sort has the bolts that connect the hubs for the split spacer set up in the ends of the couplings. The SXCST have the bolts put in from inside the spacer pointing outward towards the hubs.
