Industrial SU Type
The SU Form coupling includes a single flex plane with two hubs as well as a single disc pack. It really is ideal for angular and axial misalignment only. Two SU couplings are sometimes mixed which has a shaft
to make a floating shaft coupling. The shaft may be hollow for long light bodyweight floating shaft couplings.
Industrial SX Form
This is certainly the typical coupling style that consists of two hubs, a stock length spacer created to meet sector standard 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 obtainable in six and eight bolt designs and bore sizes up to 13 inches (330mm) around the greatest dimension. Customized spacer lengths can be produced to meet exclusive shaft separations demanded for unique applications. The SX coupling might be fitted with overload bushings to safeguard the disc packs in more than torque situations and will act as an anti-flail device. SX couplings are assembled in the time of set up around the products exactly where the coupling is going to be in service.
Industrial DI Variety
The DI Form coupling includes a “Drop-In” spacer assembly that is assembled on the factory. The coupling consists of two hubs in addition to a spacer assembly comprising of the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted to the spacer and guard rings at the factory utilizing the torque values advisable by Lovejoy for that disc pack bolts. With the hubs mounted on the shafts, the entire disc pack assembly is often “Dropped In” spot in between the two hubs. The hubs are piloted to guarantee proper centering in the spacer assembly. This piloting serves as an anti-flail characteristic and aids within the coupling’s means to meet the stability specifications mandated by API. This type coupling is built to meet the stability and anti-flail necessities specified in API-610.
Oversized, or Jumbo, hubs can be found for use with the DI Form coupling to permit for larger bore sizes on most DI coupling sizes. This permits for that utilization of smaller DI couplings in applications the place a smaller size coupling can even now accommodate the application torque.
Industrial SXC Form
The SXC Type is definitely the shut coupled variation of the SX Kind coupling. The SXC is just like the SX coupling in the disc packs are connected once the coupling is installed. Inside the near coupled units, the hubs are turned inward and are mounted within the spacer. Note that with the hubs within the spacer, the utmost bore allowed during the hub are going to be decreased. The SXC couplings is often used with one or each hubs turned outward to allow the coupling to accommodate distinct shaft separations.
Industrial SXCS and SXCST Varieties
The SXCS and SXCST Varieties have split spacers along with the disc packs is usually serviced or eliminated without having moving the hubs within the shafts and with no moving the equipment. The SXCS Form has the bolts that connect the hubs towards the split spacer set up from the ends from the couplings. The SXCST possess the bolts put in from within the spacer pointing outward towards the hubs.
