Disc Coupling Overview

Industrial SU Variety
The SU Type coupling features a single flex plane with two hubs plus a single disc pack. It is ideal for angular and axial misalignment only. Two SU couplings are often mixed which has a shaft
to create a floating shaft coupling. The shaft is usually hollow for long light fat floating shaft couplings.
Industrial SX Sort
This really is the typical coupling type that involves two hubs, a stock length spacer created to meet market common lengths, and two unitized disc packs. The coupling has two flex planes, one particular at every disc pack, enabling 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) about the largest dimension. Customized spacer lengths is often produced to meet unique shaft separations necessary for certain applications. The SX coupling could be fitted with overload bushings to guard the disc packs in in excess of torque conditions and can act as an anti-flail gadget. SX couplings are assembled at the time of installation around the gear in which the coupling will probably be in support.
Industrial DI Type
The DI Style coupling features a “Drop-In” spacer assembly that's assembled in the factory. The coupling includes two hubs along with a spacer assembly comprising from the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted for the spacer and guard rings on the factory utilizing the torque values advised by Lovejoy for that disc pack bolts. Together with the hubs mounted within the shafts, the whole disc pack assembly is usually “Dropped In” location involving the two hubs. The hubs are piloted to guarantee correct centering with the spacer assembly. This piloting serves as an anti-flail feature and aids inside the coupling’s capability to meet the stability requirements mandated by API. This type coupling is created to meet the stability and anti-flail necessities specified in API-610.
Oversized, or Jumbo, hubs can be found for use together with the DI Kind coupling to permit for greater bore sizes on most DI coupling sizes. This permits for that use of smaller DI couplings in applications wherever a smaller sized size coupling can nevertheless accommodate the application torque.
Industrial SXC Style
The SXC Type is definitely the near coupled variation in the SX Sort coupling. The SXC is much like the SX coupling in the disc packs are attached when the coupling is set up. From the close coupled units, the hubs are turned inward and are mounted within the spacer. Note that using the hubs inside the spacer, the maximum bore permitted inside the hub are going to be decreased. The SXC couplings is usually utilised with 1 or the two hubs turned outward to permit the coupling to accommodate distinct shaft separations.
Industrial SXCS and SXCST Sorts
The SXCS and SXCST Styles have split spacers along with the disc packs might be serviced or removed with out moving the hubs to the shafts and without the need of moving the equipment. The SXCS Form has the bolts that connect the hubs to the split spacer put in from the ends on the couplings. The SXCST possess the bolts set up from inside the spacer pointing outward in the direction of the hubs.
