Industrial SU Variety
The SU Variety coupling has a single flex plane with two hubs and also a single disc pack. It truly is appropriate for angular and axial misalignment only. Two SU couplings are frequently mixed using a shaft
to produce a floating shaft coupling. The shaft may be hollow for prolonged light excess weight floating shaft couplings.
Industrial SX Style
This is the normal coupling type that contains two hubs, a stock length spacer designed to meet business typical lengths, and two unitized disc packs. The coupling has two flex planes, 1 at each and every disc pack, permitting this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is obtainable in six and 8 bolt patterns and bore sizes as much as 13 inches (330mm) on the greatest size. Custom spacer lengths might be produced to meet special shaft separations needed for certain applications. The SX coupling may be fitted with overload bushings to safeguard the disc packs in over torque problems and will act as an anti-flail device. SX couplings are assembled at the time of set up about the tools the place the coupling might be in support.
Industrial DI Variety
The DI Sort coupling features a “Drop-In” spacer assembly that is assembled in the factory. The coupling consists of two hubs plus a spacer assembly comprising with the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted on the spacer and guard rings on the factory using the torque values advised by Lovejoy for the disc pack bolts. Together with the hubs mounted about the shafts, the whole disc pack assembly can be “Dropped In” spot amongst the 2 hubs. The hubs are piloted to ensure suitable centering with the spacer assembly. This piloting serves as an anti-flail characteristic and aids within the coupling’s skill to meet the balance standards mandated by API. This type coupling is created to meet the stability and anti-flail needs specified in API-610.
Oversized, or Jumbo, hubs can be found for use with the DI Variety coupling to permit for greater bore sizes on most DI coupling sizes. This permits for that use of smaller sized DI couplings in applications exactly where a smaller size coupling can nonetheless accommodate the application torque.
Industrial SXC Variety
The SXC Style will be the close coupled variation from the SX Form coupling. The SXC is much like the SX coupling in that the disc packs are attached once the coupling is installed. Within the near coupled units, the hubs are turned inward and are mounted within the spacer. Note that with the hubs inside the spacer, the maximum bore allowed while in the hub might be decreased. The SXC couplings is usually employed with a single or each hubs turned outward to permit the coupling to accommodate different shaft separations.
Industrial SXCS and SXCST Types
The SXCS and SXCST Styles have split spacers as well as the disc packs is often serviced or eliminated with out moving the hubs over the shafts and without the need of moving the gear. The SXCS Style has the bolts that connect the hubs to your split spacer installed from the ends of your couplings. The SXCST have the bolts set up from within the spacer pointing outward towards the hubs.
