Industrial SU Kind
The SU Kind coupling features a single flex plane with two hubs in addition to a single disc pack. It is actually suitable for angular and axial misalignment only. Two SU couplings are frequently mixed which has a shaft
to create a floating shaft coupling. The shaft may be hollow for lengthy light weight floating shaft couplings.
Industrial SX Form
This is often the typical coupling variety that includes two hubs, a stock length spacer developed to meet sector standard lengths, and two unitized disc packs. The coupling has two flex planes, one at each and every disc pack, permitting 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) about the greatest size. Customized spacer lengths may be produced to meet special shaft separations essential for specific applications. The SX coupling could be fitted with overload bushings to protect the disc packs in above torque circumstances and might act as an anti-flail device. SX couplings are assembled on the time of set up about the products where the coupling will likely be in services.
Industrial DI Variety
The DI Form coupling has a “Drop-In” spacer assembly that’s assembled on the factory. The coupling includes two hubs as well as a spacer assembly comprising on the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted to your spacer and guard rings at the factory applying the torque values advised by Lovejoy for your disc pack bolts. Using the hubs mounted within the shafts, the whole disc pack assembly can be “Dropped In” location among the 2 hubs. The hubs are piloted to make sure correct centering on the spacer assembly. This piloting serves as an anti-flail function and aids inside the coupling’s capability to meet the stability standards mandated by API. This type coupling is built to meet the balance and anti-flail specifications specified in API-610.
Oversized, or Jumbo, hubs can be found for use using the DI Kind coupling to permit for more substantial bore sizes on most DI coupling sizes. This enables for your use of smaller DI couplings in applications the place a smaller sized size coupling can nevertheless accommodate the application torque.
Industrial SXC Type
The SXC Variety is the near coupled variation with the SX Sort coupling. The SXC is much like the SX coupling in that the disc packs are connected once the coupling is installed. From the shut coupled units, the hubs are turned inward and are mounted within the spacer. Note that with the hubs inside the spacer, the utmost bore permitted during the hub will be decreased. The SXC couplings might be utilized with one particular or both hubs turned outward to permit the coupling to accommodate distinctive shaft separations.
Industrial SXCS and SXCST Kinds
The SXCS and SXCST Varieties have split spacers and the disc packs is often serviced or eliminated devoid of moving the hubs about the shafts and devoid of moving the gear. The SXCS Kind has the bolts that connect the hubs for the split spacer installed from your ends from the couplings. The SXCST possess the bolts put in from within the spacer pointing outward in the direction of the hubs.
