Industrial SU Type
The SU Style coupling features a single flex plane with two hubs and also a single disc pack. It’s appropriate for angular and axial misalignment only. Two SU couplings are sometimes mixed by using a shaft
to create a floating shaft coupling. The shaft could be hollow for lengthy light excess weight floating shaft couplings.
Industrial SX Sort
This really is the standard coupling kind that involves two hubs, a stock length spacer designed to meet industry normal 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 6 and eight bolt types and bore sizes up to 13 inches (330mm) around the greatest size. Custom spacer lengths might be produced to meet unique shaft separations necessary for particular applications. The SX coupling is usually fitted with overload bushings to guard the disc packs in in excess of torque disorders and may act as an anti-flail device. SX couplings are assembled in the time of installation around the tools exactly where the coupling will likely be in service.
Industrial DI Form
The DI Variety coupling has a “Drop-In” spacer assembly which is assembled with the factory. The coupling includes two hubs and also a spacer assembly comprising of your spacer, two unitized disc packs, and two guard rings. The disc packs are bolted towards the spacer and guard rings on the factory applying the torque values encouraged by Lovejoy for that disc pack bolts. Using the hubs mounted around the shafts, the complete disc pack assembly is usually “Dropped In” spot concerning the 2 hubs. The hubs are piloted to ensure good centering on the spacer assembly. This piloting serves as an anti-flail characteristic and aids from the coupling’s skill to meet the stability standards mandated by API. This fashion coupling is made to meet the balance and anti-flail needs specified in API-610.
Oversized, or Jumbo, hubs are available for use with all the DI Form coupling to permit for greater bore sizes on most DI coupling sizes. This allows for your use of smaller sized DI couplings in applications in which a smaller sized size coupling can nevertheless accommodate the application torque.
Industrial SXC Form
The SXC Style is definitely the near coupled variation with the SX Kind coupling. The SXC is similar to the SX coupling in the disc packs are connected when the coupling is put in. In the shut coupled units, the hubs are turned inward and are mounted within the spacer. Note that with the hubs within the spacer, the utmost bore permitted during the hub might be decreased. The SXC couplings can be applied with one or both hubs turned outward to allow the coupling to accommodate various shaft separations.
Industrial SXCS and SXCST Sorts
The SXCS and SXCST Styles have split spacers and the disc packs can be serviced or removed devoid of moving the hubs about the shafts and without moving the equipment. The SXCS Form has the bolts that connect the hubs to your split spacer installed in the ends from the couplings. The SXCST possess the bolts put in from within the spacer pointing outward in direction of the hubs.
