Disc Coupling Overview

Industrial SU Type
The SU Form coupling includes a single flex plane with two hubs and a single disc pack. It is suitable for angular and axial misalignment only. Two SU couplings are frequently mixed with a shaft
to make a floating shaft coupling. The shaft may be hollow for extended light excess weight floating shaft couplings.
Industrial SX Style
This really is the typical coupling style that consists of two hubs, a stock length spacer created to meet business conventional lengths, and two unitized disc packs. The coupling has two flex planes, one particular at every single disc pack, enabling this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is obtainable in six and 8 bolt patterns and bore sizes up to 13 inches (330mm) about the biggest dimension. Customized spacer lengths is often produced to meet special shaft separations expected for particular applications. The SX coupling is usually fitted with overload bushings to safeguard the disc packs in above torque conditions and will act as an anti-flail gadget. SX couplings are assembled with the time of installation to the products in which the coupling will probably be in support.
Industrial DI Kind
The DI Variety coupling includes a “Drop-In” spacer assembly which is assembled with the factory. The coupling consists of two hubs plus a spacer assembly comprising of the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted to your spacer and guard rings with the factory working with the torque values recommended by Lovejoy for that disc pack bolts. Using the hubs mounted to the shafts, the entire disc pack assembly could be “Dropped In” location amongst the 2 hubs. The hubs are piloted to guarantee correct centering in the spacer assembly. This piloting serves as an anti-flail characteristic and aids from the coupling’s potential to meet the balance requirements mandated by API. This type coupling is developed to meet the stability and anti-flail needs specified in API-610.
Oversized, or Jumbo, hubs are available for use together with the DI Type coupling to allow for larger bore sizes on most DI coupling sizes. This allows for that utilization of smaller sized DI couplings in applications in which a smaller sized dimension coupling can even now accommodate the application torque.
Industrial SXC Type
The SXC Type is definitely the near coupled variation with the SX Variety coupling. The SXC is similar to the SX coupling in the disc packs are connected when the coupling is put in. In the close 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 while in the hub is going to be decreased. The SXC couplings can be applied with one or the two hubs turned outward to permit the coupling to accommodate distinct shaft separations.
Industrial SXCS and SXCST Styles
The SXCS and SXCST Types have split spacers as well as disc packs could be serviced or removed devoid of moving the hubs on the shafts and with no moving the gear. The SXCS Sort has the bolts that connect the hubs on the split spacer put in from the ends on the couplings. The SXCST have the bolts set up from inside the spacer pointing outward in direction of the hubs.
