Industrial SU Type
The SU Sort coupling features a single flex plane with two hubs and also a single disc pack. It is ideal for angular and axial misalignment only. Two SU couplings tend to be mixed having a shaft
to produce a floating shaft coupling. The shaft is often hollow for prolonged light bodyweight floating shaft couplings.
Industrial SX Sort
This really is the regular coupling kind that consists of two hubs, a stock length spacer designed to meet field standard lengths, and two unitized disc packs. The coupling has two flex planes, a single at each disc pack, making it possible for this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is available in 6 and 8 bolt designs and bore sizes as much as 13 inches (330mm) around the greatest size. Custom spacer lengths can be produced to meet particular shaft separations needed for certain applications. The SX coupling might be fitted with overload bushings to protect the disc packs in more than torque conditions and will act as an anti-flail device. SX couplings are assembled with the time of set up around the products exactly where the coupling are going to be in service.
Industrial DI Variety
The DI Kind coupling has a “Drop-In” spacer assembly that is assembled on the factory. The coupling consists of two hubs in addition to a spacer assembly comprising from the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted on the spacer and guard rings with the factory working with the torque values recommended by Lovejoy for the disc pack bolts. Using the hubs mounted to the shafts, the complete disc pack assembly can be “Dropped In” place between the 2 hubs. The hubs are piloted to guarantee appropriate centering with the spacer assembly. This piloting serves as an anti-flail feature and aids during the coupling’s skill to meet the balance requirements mandated by API. This design coupling is made to meet the stability and anti-flail needs specified in API-610.
Oversized, or Jumbo, hubs are available for use using the DI Style coupling to allow for larger bore sizes on most DI coupling sizes. This enables to the utilization of smaller DI couplings in applications wherever a smaller size coupling can even now accommodate the application torque.
Industrial SXC Sort
The SXC Sort is definitely the near coupled variation in the SX Form coupling. The SXC is just like the SX coupling in that the disc packs are connected when the coupling is installed. While in the close coupled units, the hubs are turned inward and are mounted within the spacer. Note that with the hubs within the spacer, the maximum bore allowed during the hub will likely be decreased. The SXC couplings might be employed with one particular or the two hubs turned outward to allow the coupling to accommodate diverse shaft separations.
Industrial SXCS and SXCST Types
The SXCS and SXCST Styles have split spacers as well as disc packs can be serviced or removed devoid of moving the hubs on the shafts and without the need of moving the equipment. The SXCS Variety has the bolts that connect the hubs for the split spacer put in from the ends on the couplings. The SXCST have the bolts installed from inside the spacer pointing outward towards the hubs.
