Industrial SU Style
The SU Style coupling has a single flex plane with two hubs in addition to a single disc pack. It is ideal for angular and axial misalignment only. Two SU couplings tend to be mixed using a shaft
to produce a floating shaft coupling. The shaft can be hollow for prolonged light excess weight floating shaft couplings.
Industrial SX Type
This is often the standard coupling sort that includes two hubs, a stock length spacer designed to meet marketplace typical lengths, and two unitized disc packs. The coupling has two flex planes, 1 at each and every disc pack, enabling this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is available in six and 8 bolt types and bore sizes up to 13 inches (330mm) around the largest dimension. Customized spacer lengths may be manufactured to meet specific shaft separations needed for distinct applications. The SX coupling might be fitted with overload bushings to guard the disc packs in in excess of torque conditions and can act as an anti-flail gadget. SX couplings are assembled on the time of set up around the products exactly where the coupling might be in service.
Industrial DI Sort
The DI Form coupling includes a “Drop-In” spacer assembly that is definitely assembled in the factory. The coupling consists of two hubs along with a spacer assembly comprising from the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted towards the spacer and guard rings at the factory applying the torque values recommended by Lovejoy to the disc pack bolts. With the hubs mounted over the shafts, the entire disc pack assembly may be “Dropped In” location between the 2 hubs. The hubs are piloted to ensure right centering in the spacer assembly. This piloting serves as an anti-flail function and aids within the coupling’s potential to meet the balance standards mandated by API. This fashion coupling is intended to meet the balance and anti-flail needs specified in API-610.
Oversized, or Jumbo, hubs are available for use together with the DI Sort coupling to permit for larger bore sizes on most DI coupling sizes. This allows for that use of smaller DI couplings in applications where a smaller sized size coupling can nonetheless accommodate the application torque.
Industrial SXC Kind
The SXC Variety may be the shut coupled variation in the SX Form coupling. The SXC is just like the SX coupling in the disc packs are attached when the coupling is set up. During the shut coupled units, the hubs are turned inward and are mounted inside the spacer. Note that with the hubs within the spacer, the maximum bore allowed from the hub will be decreased. The SXC couplings can be applied with 1 or each hubs turned outward to permit the coupling to accommodate diverse shaft separations.
Industrial SXCS and SXCST Forms
The SXCS and SXCST Varieties have split spacers and also the disc packs could be serviced or eliminated with out moving the hubs around the shafts and with no moving the tools. The SXCS Variety has the bolts that connect the hubs for the split spacer put in from the ends of the couplings. The SXCST possess the bolts set up from inside the spacer pointing outward in direction of the hubs.
