Industrial SU Style
The SU Form coupling features a single flex plane with two hubs and also a single disc pack. It is appropriate for angular and axial misalignment only. Two SU couplings are sometimes mixed using a shaft
to make a floating shaft coupling. The shaft may be hollow for lengthy light weight floating shaft couplings.
Industrial SX Sort
This is the conventional coupling type that involves two hubs, a stock length spacer built to meet field regular lengths, and two unitized disc packs. The coupling has two flex planes, 1 at every disc pack, allowing this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is accessible in six and eight bolt patterns and bore sizes up to 13 inches (330mm) around the biggest size. Custom spacer lengths could be produced to meet special shaft separations necessary for specific applications. The SX coupling is often fitted with overload bushings to guard the disc packs in in excess of torque ailments and may act as an anti-flail gadget. SX couplings are assembled in the time of installation on the tools where the coupling will probably be in service.
Industrial DI Variety
The DI Sort coupling includes a “Drop-In” spacer assembly which is assembled with the factory. The coupling includes two hubs plus a spacer assembly comprising with the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted to the spacer and guard rings in the factory working with the torque values advisable by Lovejoy for that disc pack bolts. With the hubs mounted on the shafts, the complete disc pack assembly is often “Dropped In” location involving the 2 hubs. The hubs are piloted to ensure right centering in the spacer assembly. This piloting serves as an anti-flail characteristic and aids while in the coupling’s potential to meet the stability standards mandated by API. This style coupling is created to meet the stability and anti-flail specifications specified in API-610.
Oversized, or Jumbo, hubs are available for use with all the DI Variety coupling to permit for bigger bore sizes on most DI coupling sizes. This permits for the use of smaller sized DI couplings in applications in which a smaller dimension coupling can nonetheless accommodate the application torque.
Industrial SXC Variety
The SXC Form could be the near coupled variation on the SX Type coupling. The SXC is similar to the SX coupling in the disc packs are connected when the coupling is set up. During the near coupled units, the hubs are turned inward and are mounted inside the spacer. Note that together with the hubs inside the spacer, the utmost bore permitted during the hub is going to be decreased. The SXC couplings is usually utilised with one particular or the two hubs turned outward to permit the coupling to accommodate different shaft separations.
Industrial SXCS and SXCST Varieties
The SXCS and SXCST Forms have split spacers as well as disc packs is usually serviced or removed with no moving the hubs within the shafts and without moving the equipment. The SXCS Form has the bolts that connect the hubs on the split spacer installed in the ends of the couplings. The SXCST possess the bolts set up from within the spacer pointing outward in the direction of the hubs.
