Industrial SU Style
The SU Sort coupling includes a single flex plane with two hubs in addition to a single disc pack. It’s appropriate for angular and axial misalignment only. Two SU couplings are sometimes combined which has a shaft
to generate a floating shaft coupling. The shaft can be hollow for extended light bodyweight floating shaft couplings.
Industrial SX Type
This is certainly the standard coupling form that incorporates two hubs, a stock length spacer created to meet field standard lengths, and two unitized disc packs. The coupling has two flex planes, one particular at every disc pack, permitting this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is obtainable in 6 and eight bolt patterns and bore sizes up to 13 inches (330mm) about the greatest size. Customized spacer lengths could be produced to meet special shaft separations demanded for certain applications. The SX coupling might be fitted with overload bushings to protect the disc packs in above torque problems and will act as an anti-flail gadget. SX couplings are assembled at the time of installation within the gear in which the coupling are going to be in service.
Industrial DI Type
The DI Form coupling includes a “Drop-In” spacer assembly that may be assembled in the factory. The coupling consists of two hubs as well as 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 at the factory applying the torque values advisable by Lovejoy for the disc pack bolts. Using the hubs mounted about the shafts, the entire disc pack assembly may be “Dropped In” spot among the two hubs. The hubs are piloted to make certain good centering of your spacer assembly. This piloting serves as an anti-flail function and aids while in the coupling’s means to meet the balance specifications mandated by API. This fashion coupling is intended to meet the balance and anti-flail necessities specified in API-610.
Oversized, or Jumbo, hubs are available for use using the DI Kind coupling to permit for bigger bore sizes on most DI coupling sizes. This permits for your utilization of smaller sized DI couplings in applications the place a smaller sized size coupling can nevertheless accommodate the application torque.
Industrial SXC Variety
The SXC Form is definitely the close coupled variation from the SX Form coupling. The SXC is just like the SX coupling in that the disc packs are connected once the coupling is installed. During the near coupled units, the hubs are turned inward and are mounted inside the spacer. Note that using the hubs inside the spacer, the maximum bore allowed inside the hub might be decreased. The SXC couplings may be utilized with a single or each hubs turned outward to allow the coupling to accommodate various shaft separations.
Industrial SXCS and SXCST Forms
The SXCS and SXCST Varieties have split spacers as well as disc packs is usually serviced or eliminated with out moving the hubs to the shafts and with no moving the gear. The SXCS Variety has the bolts that connect the hubs to your split spacer set up in the ends from the couplings. The SXCST have the bolts put in from within the spacer pointing outward towards the hubs.
