Industrial SU Form
The SU Kind coupling includes a single flex plane with two hubs and also a single disc pack. It is suitable for angular and axial misalignment only. Two SU couplings are sometimes mixed that has a shaft
to produce a floating shaft coupling. The shaft is usually hollow for lengthy light bodyweight floating shaft couplings.
Industrial SX Style
That is the conventional coupling variety that involves two hubs, a stock length spacer developed to meet field conventional lengths, and two unitized disc packs. The coupling has two flex planes, one particular at each disc pack, allowing this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is accessible in six and 8 bolt patterns and bore sizes up to 13 inches (330mm) to the greatest size. Custom spacer lengths could be produced to meet exclusive shaft separations expected for particular applications. The SX coupling might be fitted with overload bushings to safeguard the disc packs in more than torque ailments and might act as an anti-flail device. SX couplings are assembled at the time of installation around the equipment exactly where the coupling are going to be in support.
Industrial DI Style
The DI Variety coupling includes a “Drop-In” spacer assembly that is definitely assembled at the factory. The coupling consists of two hubs along with a spacer assembly comprising of the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted for the spacer and guard rings with the factory working with the torque values advised by Lovejoy for the disc pack bolts. With the hubs mounted within the shafts, the entire disc pack assembly can be “Dropped In” location amongst the 2 hubs. The hubs are piloted to make sure proper centering with the spacer assembly. This piloting serves as an anti-flail function and aids from the coupling’s skill to meet the balance specifications mandated by API. This style coupling is built to meet the stability and anti-flail needs specified in API-610.
Oversized, or Jumbo, hubs are available for use with the DI Type coupling to allow for bigger bore sizes on most DI coupling sizes. This permits for your utilization of smaller sized DI couplings in applications in which a smaller sized size coupling can nonetheless accommodate the application torque.
Industrial SXC Form
The SXC Variety could be the close coupled variation of the SX Variety coupling. The SXC is much like the SX coupling in that the disc packs are connected once the coupling is put in. From the close coupled units, the hubs are turned inward and therefore are mounted within the spacer. Note that using the hubs within the spacer, the maximum bore allowed within the hub are going to be decreased. The SXC couplings can be used with 1 or each hubs turned outward to permit the coupling to accommodate distinct shaft separations.
Industrial SXCS and SXCST Styles
The SXCS and SXCST Types have split spacers and the disc packs is often serviced or removed without having moving the hubs to the shafts and without having moving the gear. The SXCS Form has the bolts that connect the hubs on the split spacer installed from your ends of the couplings. The SXCST have the bolts set up from within the spacer pointing outward in direction of the hubs.
