Industrial SU Type
The SU Sort coupling has a single flex plane with two hubs and a single disc pack. It really is appropriate for angular and axial misalignment only. Two SU couplings are often combined which has a shaft
to generate a floating shaft coupling. The shaft may be hollow for extended light fat floating shaft couplings.
Industrial SX Kind
This is certainly the standard coupling style that incorporates two hubs, a stock length spacer created to meet business regular 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 obtainable in 6 and eight bolt types and bore sizes as much as 13 inches (330mm) over the largest size. Customized spacer lengths is often produced to meet special shaft separations required for distinct applications. The SX coupling is usually fitted with overload bushings to protect the disc packs in above torque disorders and will act as an anti-flail gadget. SX couplings are assembled in the time of installation within the gear in which the coupling will probably be in service.
Industrial DI Kind
The DI Form coupling has a “Drop-In” spacer assembly that is assembled in the factory. The coupling consists of two hubs plus a spacer assembly comprising in 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 advisable by Lovejoy for your disc pack bolts. Using the hubs mounted to the shafts, the entire disc pack assembly could be “Dropped In” spot concerning the two hubs. The hubs are piloted to make certain correct centering of the spacer assembly. This piloting serves as an anti-flail characteristic and aids during the coupling’s means to meet the balance standards mandated by API. This fashion coupling is developed to meet the balance and anti-flail necessities specified in API-610.
Oversized, or Jumbo, hubs are available for use using the DI Sort coupling to permit for greater bore sizes on most DI coupling sizes. This allows to the utilization of smaller sized DI couplings in applications the place a smaller sized size coupling can nevertheless accommodate the application torque.
Industrial SXC Type
The SXC Form is definitely the near coupled variation from the SX Style coupling. The SXC is just like the SX coupling in the disc packs are connected when the coupling is installed. During the near coupled units, the hubs are turned inward and therefore are mounted within the spacer. Note that together with the hubs within the spacer, the maximum bore allowed while in the hub will be decreased. The SXC couplings could be employed with a single or the two hubs turned outward to permit the coupling to accommodate diverse shaft separations.
Industrial SXCS and SXCST Types
The SXCS and SXCST Varieties have split spacers and also the disc packs is usually serviced or eliminated devoid of moving the hubs on the shafts and with no moving the tools. The SXCS Style has the bolts that connect the hubs to your split spacer set up through the ends from the couplings. The SXCST have the bolts put in from inside the spacer pointing outward towards the hubs.
