Industrial SU Style
The SU Form coupling features a single flex plane with two hubs as well as a single disc pack. It is appropriate for angular and axial misalignment only. Two SU couplings are frequently mixed using a shaft
to make a floating shaft coupling. The shaft may be hollow for long light weight floating shaft couplings.
Industrial SX Kind
This is certainly the conventional coupling type that involves two hubs, a stock length spacer built to meet field standard lengths, and two unitized disc packs. The coupling has two flex planes, one 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) on the biggest size. Custom spacer lengths could be manufactured to meet special shaft separations needed for precise applications. The SX coupling is often fitted with overload bushings to protect the disc packs in more than torque ailments and may act as an anti-flail gadget. SX couplings are assembled at the time of set up on the tools where the coupling will probably be in service.
Industrial DI Variety
The DI Kind coupling features a “Drop-In” spacer assembly that’s assembled on 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 employing the torque values advisable by Lovejoy to the disc pack bolts. With the hubs mounted on the shafts, the whole disc pack assembly is often “Dropped In” location among the 2 hubs. The hubs are piloted to guarantee right centering in the spacer assembly. This piloting serves as an anti-flail function and aids within the coupling’s capability to meet the balance 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 using the DI Kind coupling to allow for larger bore sizes on most DI coupling sizes. This enables for the utilization of smaller sized DI couplings in applications in which a smaller dimension coupling can nonetheless accommodate the application torque.
Industrial SXC Kind
The SXC Sort could be the near coupled variation in 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 with all the hubs inside the spacer, the maximum bore allowed while in the hub will likely 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 Varieties have split spacers as well as disc packs is usually serviced or removed with no moving the hubs on the shafts and devoid of moving the equipment. The SXCS Variety 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.
