Disc Coupling Overview

Industrial SU Form
The SU Type coupling features a single flex plane with two hubs plus a single disc pack. It can be appropriate for angular and axial misalignment only. Two SU couplings are frequently mixed with a shaft
to produce a floating shaft coupling. The shaft can be hollow for long light fat floating shaft couplings.
Industrial SX Variety
This is often the typical coupling variety that incorporates two hubs, a stock length spacer designed to meet marketplace typical lengths, and two unitized disc packs. The coupling has two flex planes, 1 at each and 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 styles and bore sizes as much as 13 inches (330mm) within the greatest dimension. Customized spacer lengths is often produced to meet distinctive shaft separations demanded for particular applications. The SX coupling is usually fitted with overload bushings to protect the disc packs in more than torque circumstances and may act as an anti-flail gadget. SX couplings are assembled with the time of installation around the gear wherever the coupling is going to be in service.
Industrial DI Sort
The DI Style coupling has a “Drop-In” spacer assembly which is assembled on the factory. The coupling consists of two hubs and a spacer assembly comprising of your spacer, two unitized disc packs, and two guard rings. The disc packs are bolted to your spacer and guard rings with the factory using the torque values encouraged by Lovejoy to the disc pack bolts. With all the hubs mounted around the shafts, the complete disc pack assembly might be “Dropped In” area concerning the 2 hubs. The hubs are piloted to guarantee correct centering of your spacer assembly. This piloting serves as an anti-flail function and aids in the coupling’s ability to meet the stability standards mandated by API. This style coupling is built to meet the balance and anti-flail needs specified in API-610.
Oversized, or Jumbo, hubs are available for use with the DI Form coupling to permit for larger bore sizes on most DI coupling sizes. This enables to the utilization of smaller sized DI couplings in applications wherever a smaller sized dimension coupling can nonetheless accommodate the application torque.
Industrial SXC Type
The SXC Style is definitely the close coupled variation of the SX Variety coupling. The SXC is similar to the SX coupling in that the disc packs are connected once the coupling is put in. From the close coupled units, the hubs are turned inward and therefore are mounted within the spacer. Note that with all the hubs within the spacer, the utmost bore allowed from the hub will be decreased. The SXC couplings could be applied with a single or each hubs turned outward to allow the coupling to accommodate various shaft separations.
Industrial SXCS and SXCST Kinds
The SXCS and SXCST Kinds have split spacers as well as the disc packs can be serviced or eliminated without moving the hubs about the shafts and without the need of moving the products. The SXCS Kind has the bolts that connect the hubs towards the split spacer installed from the ends on the couplings. The SXCST possess the bolts put in from inside the spacer pointing outward towards the hubs.
