Disc Coupling Overview

Industrial SU Type
The SU Type coupling has a single flex plane with two hubs in addition to a single disc pack. It really is ideal for angular and axial misalignment only. Two SU couplings are frequently combined which has a shaft
for making a floating shaft coupling. The shaft could be hollow for prolonged light weight floating shaft couplings.
Industrial SX Kind
This really is the conventional coupling type that involves two hubs, a stock length spacer made to meet business regular lengths, and two unitized disc packs. The coupling has two flex planes, a single at each disc pack, permitting this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is available in six and eight bolt styles and bore sizes as much as 13 inches (330mm) on the largest size. Custom spacer lengths could be manufactured to meet particular shaft separations necessary for certain applications. The SX coupling might be fitted with overload bushings to safeguard the disc packs in over torque situations and may act as an anti-flail gadget. SX couplings are assembled at the time of set up about the tools where the coupling will probably be in support.
Industrial DI Form
The DI Variety coupling has a “Drop-In” spacer assembly that is assembled at the factory. The coupling consists of two hubs along with a spacer assembly comprising of your spacer, two unitized disc packs, and two guard rings. The disc packs are bolted to the spacer and guard rings at the factory employing the torque values recommended by Lovejoy for the disc pack bolts. Using the hubs mounted on the shafts, the entire disc pack assembly can be “Dropped In” spot between the 2 hubs. The hubs are piloted to be sure correct centering of the spacer assembly. This piloting serves as an anti-flail function and aids within the coupling’s ability to meet the balance requirements mandated by API. This style coupling is developed to meet the stability and anti-flail prerequisites specified in API-610.
Oversized, or Jumbo, hubs are available for use with all the DI Style coupling to allow for more substantial bore sizes on most DI coupling sizes. This enables for that use of smaller DI couplings in applications exactly where a smaller size coupling can nonetheless accommodate the application torque.
Industrial SXC Sort
The SXC Form may be the shut coupled variation with the SX Form coupling. The SXC is just like the SX coupling in that the disc packs are attached once the coupling is put in. During the near coupled units, the hubs are turned inward and are mounted within the spacer. Note that together with the hubs inside the spacer, the utmost bore permitted in the hub are going to be decreased. The SXC couplings might be employed with 1 or each hubs turned outward to permit the coupling to accommodate various shaft separations.
Industrial SXCS and SXCST Types
The SXCS and SXCST Kinds have split spacers plus the disc packs could be serviced or removed without having moving the hubs within the shafts and without having moving the gear. The SXCS Form has the bolts that connect the hubs towards the split spacer put in from your ends on the couplings. The SXCST have the bolts put in from within the spacer pointing outward in the direction of the hubs.
