Industrial SU Type
The SU Form coupling has a single flex plane with two hubs in addition to a single disc pack. It is suitable for angular and axial misalignment only. Two SU couplings are often combined that has a shaft
to make a floating shaft coupling. The shaft may be hollow for long light excess weight floating shaft couplings.
Industrial SX Style
This is certainly the regular coupling sort that incorporates two hubs, a stock length spacer designed to meet market common lengths, and two unitized disc packs. The coupling has two flex planes, 1 at each disc pack, making it possible for this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is obtainable in six and 8 bolt types and bore sizes as much as 13 inches (330mm) over the largest dimension. Customized spacer lengths can be produced to meet distinctive shaft separations expected for particular applications. The SX coupling is usually fitted with overload bushings to guard the disc packs in more than torque conditions and will act as an anti-flail device. SX couplings are assembled at the time of set up on the gear where the coupling are going to be in support.
Industrial DI Form
The DI Kind coupling features a “Drop-In” spacer assembly that is definitely assembled at the factory. The coupling includes two hubs along with a spacer assembly comprising on the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted to the spacer and guard rings at the factory using the torque values proposed by Lovejoy for that disc pack bolts. With the hubs mounted on the shafts, the whole disc pack assembly may be “Dropped In” location amongst the 2 hubs. The hubs are piloted to be sure proper centering of the spacer assembly. This piloting serves as an anti-flail function and aids while in the coupling’s skill to meet the balance specifications mandated by API. This fashion coupling is made to meet the balance and anti-flail needs specified in API-610.
Oversized, or Jumbo, hubs can be found for use together with the DI Form coupling to allow for larger bore sizes on most DI coupling sizes. This allows for the use of smaller DI couplings in applications wherever a smaller dimension coupling can still accommodate the application torque.
Industrial SXC Style
The SXC Kind will be the close coupled variation of the SX Variety coupling. The SXC is similar to the SX coupling in the disc packs are attached when the coupling is installed. While in the near coupled units, the hubs are turned inward and are mounted inside the spacer. Note that with all the hubs inside the spacer, the maximum bore allowed from the hub will probably be decreased. The SXC couplings is often made use of with 1 or the two hubs turned outward to allow the coupling to accommodate distinctive shaft separations.
Industrial SXCS and SXCST Types
The SXCS and SXCST Sorts have split spacers and also the disc packs may be serviced or removed with no moving the hubs within the shafts and without the need of moving the gear. The SXCS Form has the bolts that connect the hubs to your split spacer put in from the ends of the couplings. The SXCST have the bolts put in from within the spacer pointing outward towards the hubs.
