Industrial SU Type
The SU Style coupling features a single flex plane with two hubs plus a single disc pack. It can be appropriate for angular and axial misalignment only. Two SU couplings are frequently combined having a shaft
to produce a floating shaft coupling. The shaft can be hollow for lengthy light excess weight floating shaft couplings.
Industrial SX Variety
That is the typical coupling variety that includes two hubs, a stock length spacer developed to meet business conventional lengths, and two unitized disc packs. The coupling has two flex planes, a single at each and every disc pack, making it possible for this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is accessible in six and eight bolt types and bore sizes up to 13 inches (330mm) to the largest size. Customized spacer lengths is usually manufactured to meet exclusive shaft separations required for precise applications. The SX coupling can be fitted with overload bushings to guard the disc packs in in excess of torque situations and might act as an anti-flail gadget. SX couplings are assembled with the time of set up on the tools wherever the coupling will be in support.
Industrial DI Kind
The DI Variety coupling includes a “Drop-In” spacer assembly that may be assembled with the factory. The coupling consists of two hubs plus a spacer assembly comprising on the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted to the spacer and guard rings at the factory working with the torque values proposed by Lovejoy for the disc pack bolts. Using the hubs mounted around the shafts, the complete disc pack assembly is often “Dropped In” spot involving the 2 hubs. The hubs are piloted to make certain suitable centering with the spacer assembly. This piloting serves as an anti-flail feature and aids while in the coupling’s potential to meet the stability specifications mandated by API. This type coupling is made to meet the balance and anti-flail demands specified in API-610.
Oversized, or Jumbo, hubs are available for use with the DI Style coupling to permit for larger bore sizes on most DI coupling sizes. This permits to the utilization of smaller DI couplings in applications the place a smaller sized dimension coupling can nevertheless accommodate the application torque.
Industrial SXC Type
The SXC Kind may be the close coupled variation in the SX Style coupling. The SXC is much like the SX coupling in the disc packs are attached once the coupling is put in. While in the shut coupled units, the hubs are turned inward and therefore are mounted inside the spacer. Note that with the hubs inside the spacer, the maximum bore allowed while in the hub are going to be decreased. The SXC couplings is usually utilized with 1 or each hubs turned outward to permit the coupling to accommodate diverse shaft separations.
Industrial SXCS and SXCST Types
The SXCS and SXCST Varieties have split spacers and the disc packs may be serviced or eliminated devoid of moving the hubs about the shafts and without moving the equipment. The SXCS Type has the bolts that connect the hubs to the split spacer installed through the ends with the couplings. The SXCST possess the bolts set up from within the spacer pointing outward in the direction of the hubs.
