Industrial SU Variety
The SU Type coupling features a single flex plane with two hubs and also a single disc pack. It can be suitable for angular and axial misalignment only. Two SU couplings are frequently combined which has a shaft
to make a floating shaft coupling. The shaft may be hollow for long light excess weight floating shaft couplings.
Industrial SX Variety
This is often the standard coupling type that consists of two hubs, a stock length spacer intended to meet sector regular lengths, and two unitized disc packs. The coupling has two flex planes, 1 at just about every disc pack, allowing this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is accessible in six and 8 bolt models and bore sizes as much as 13 inches (330mm) over the greatest dimension. Customized spacer lengths is often produced to meet unique shaft separations expected for precise applications. The SX coupling can be fitted with overload bushings to safeguard the disc packs in in excess of torque ailments and can act as an anti-flail gadget. SX couplings are assembled in the time of installation over the tools where the coupling are going to be in support.
Industrial DI Type
The DI Kind coupling includes a “Drop-In” spacer assembly that may be assembled on the factory. The coupling includes two hubs along with a spacer assembly comprising in the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted for the spacer and guard rings at the factory employing the torque values recommended by Lovejoy to the disc pack bolts. Together with the hubs mounted on the shafts, the complete disc pack assembly is usually “Dropped In” area between the two hubs. The hubs are piloted to make certain correct centering in the spacer assembly. This piloting serves as an anti-flail function and aids inside the coupling’s potential to meet the stability specifications mandated by API. This fashion coupling is created to meet the stability and anti-flail requirements specified in API-610.
Oversized, or Jumbo, hubs can be found for use using the DI Variety coupling to allow for bigger bore sizes on most DI coupling sizes. This permits for that utilization of smaller DI couplings in applications where a smaller size coupling can still accommodate the application torque.
Industrial SXC Style
The SXC Form is definitely the near coupled variation of the SX Form coupling. The SXC is similar to the SX coupling in that the disc packs are attached when the coupling is set up. In the shut coupled units, the hubs are turned inward and are mounted inside the spacer. Note that with the hubs inside the spacer, the maximum bore allowed inside the hub is going to be decreased. The SXC couplings may be utilized with one particular or the two hubs turned outward to allow the coupling to accommodate unique shaft separations.
Industrial SXCS and SXCST Styles
The SXCS and SXCST Kinds have split spacers plus the disc packs can be serviced or eliminated without the need of moving the hubs within the shafts and with out moving the equipment. The SXCS Type has the bolts that connect the hubs for the split spacer set up through the ends from the couplings. The SXCST possess the bolts put in from within the spacer pointing outward in direction of the hubs.
