Disc Coupling Overview

Industrial SU Type
The SU Style coupling has a single flex plane with two hubs as well as a single disc pack. It is suitable for angular and axial misalignment only. Two SU couplings are sometimes mixed with a shaft
to produce a floating shaft coupling. The shaft is often hollow for long light bodyweight floating shaft couplings.
Industrial SX Style
This is certainly the typical coupling kind that includes two hubs, a stock length spacer designed to meet field regular lengths, and two unitized disc packs. The coupling has two flex planes, one at every single disc pack, allowing this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is accessible in six and eight bolt types and bore sizes as much as 13 inches (330mm) on the biggest dimension. Customized spacer lengths is usually produced to meet particular shaft separations expected for specific applications. The SX coupling could be fitted with overload bushings to safeguard the disc packs in above torque problems and can act as an anti-flail device. SX couplings are assembled in the time of installation within the equipment wherever the coupling will be in support.
Industrial DI Style
The DI Style coupling has a “Drop-In” spacer assembly that’s assembled in the factory. The coupling consists of two hubs plus 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 on the factory using the torque values suggested by Lovejoy to the disc pack bolts. With the hubs mounted around the shafts, the whole disc pack assembly is often “Dropped In” place among the two hubs. The hubs are piloted to guarantee appropriate centering with the spacer assembly. This piloting serves as an anti-flail attribute and aids within the coupling’s means to meet the balance standards mandated by API. This style coupling is made to meet the balance and anti-flail specifications specified in API-610.
Oversized, or Jumbo, hubs are available for use with all the DI Variety coupling to permit for bigger bore sizes on most DI coupling sizes. This permits to the utilization of smaller sized DI couplings in applications where a smaller dimension coupling can nevertheless accommodate the application torque.
Industrial SXC Form
The SXC Kind is the shut coupled variation with the SX Sort coupling. The SXC is just like the SX coupling in the disc packs are attached once the coupling is set up. While in the near coupled units, the hubs are turned inward and therefore are mounted within the spacer. Note that with the hubs inside the spacer, the maximum bore permitted within the hub will probably be decreased. The SXC couplings might be utilised with a single or each hubs turned outward to permit the coupling to accommodate various shaft separations.
Industrial SXCS and SXCST Types
The SXCS and SXCST Forms have split spacers as well as the disc packs might be serviced or eliminated without having moving the hubs about the shafts and devoid of moving the tools. The SXCS Sort has the bolts that connect the hubs on the split spacer installed from the ends with the couplings. The SXCST possess the bolts installed from within the spacer pointing outward towards the hubs.
