Disc Coupling Overview

Industrial SU Type
The SU Style coupling includes a single flex plane with two hubs along with a single disc pack. It is actually ideal for angular and axial misalignment only. Two SU couplings are often combined which has a shaft
for making a floating shaft coupling. The shaft is often hollow for lengthy light fat floating shaft couplings.
Industrial SX Sort
That is the conventional coupling variety that incorporates two hubs, a stock length spacer made to meet marketplace regular lengths, and two unitized disc packs. The coupling has two flex planes, one particular at just about every disc pack, making it possible for this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is available in 6 and eight bolt models and bore sizes up to 13 inches (330mm) about the biggest dimension. Customized spacer lengths can be manufactured to meet particular shaft separations essential for unique applications. The SX coupling is often fitted with overload bushings to protect the disc packs in above torque disorders and may act as an anti-flail gadget. SX couplings are assembled on the time of installation on the equipment exactly where the coupling will probably be in service.
Industrial DI Style
The DI Style coupling includes a “Drop-In” spacer assembly that is certainly assembled with the factory. The coupling includes two hubs and a spacer assembly comprising from the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted towards the spacer and guard rings at the factory employing the torque values proposed by Lovejoy to the disc pack bolts. Using the hubs mounted on the shafts, the entire disc pack assembly could be “Dropped In” place between the two hubs. The hubs are piloted to make certain good centering from the spacer assembly. This piloting serves as an anti-flail feature and aids from the coupling’s capability to meet the stability specifications mandated by API. This style coupling is built to meet the balance and anti-flail prerequisites specified in API-610.
Oversized, or Jumbo, hubs are available for use using the DI Type coupling to allow for larger bore sizes on most DI coupling sizes. This enables for your utilization of smaller DI couplings in applications the place a smaller sized dimension coupling can nevertheless accommodate the application torque.
Industrial SXC Type
The SXC Sort could be the near coupled variation with the SX Type coupling. The SXC is similar to the SX coupling in the disc packs are connected when the coupling is set up. From the shut coupled units, the hubs are turned inward and therefore are mounted inside the spacer. Note that with all the hubs within the spacer, the maximum bore permitted in the hub will be decreased. The SXC couplings may be made use of with one or both hubs turned outward to allow the coupling to accommodate distinct shaft separations.
Industrial SXCS and SXCST Sorts
The SXCS and SXCST Varieties have split spacers as well as disc packs can be serviced or removed devoid of moving the hubs within the shafts and without having moving the products. The SXCS Sort has the bolts that connect the hubs for the split spacer put in from your ends from the couplings. The SXCST possess the bolts installed from inside the spacer pointing outward in the direction of the hubs.
