Disc Coupling Overview

Industrial SU Form
The SU Kind coupling features a single flex plane with two hubs as well as a single disc pack. It can be appropriate for angular and axial misalignment only. Two SU couplings are sometimes mixed that has a shaft
for making a floating shaft coupling. The shaft is often hollow for long light excess weight floating shaft couplings.
Industrial SX Variety
This is certainly the typical coupling type that contains two hubs, a stock length spacer created to meet field conventional lengths, and two unitized disc packs. The coupling has two flex planes, a single at every single disc pack, allowing this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is available in 6 and eight bolt patterns and bore sizes as much as 13 inches (330mm) about the biggest size. Custom spacer lengths might be produced to meet particular shaft separations necessary for precise applications. The SX coupling might be fitted with overload bushings to guard the disc packs in more than torque disorders and may act as an anti-flail device. SX couplings are assembled at the time of set up within the products the place the coupling will likely be in support.
Industrial DI Style
The DI Variety coupling features a “Drop-In” spacer assembly which is assembled in 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 to your spacer and guard rings at the factory working with the torque values suggested by Lovejoy to the disc pack bolts. Together with the hubs mounted about the shafts, the whole disc pack assembly could be “Dropped In” area involving the two hubs. The hubs are piloted to guarantee proper centering from the spacer assembly. This piloting serves as an anti-flail feature and aids inside the coupling’s skill to meet the stability standards mandated by API. This style coupling is developed to meet the stability and anti-flail needs specified in API-610.
Oversized, or Jumbo, hubs can be found for use using the DI Style coupling to allow for bigger bore sizes on most DI coupling sizes. This enables for your utilization of smaller sized DI couplings in applications wherever a smaller sized dimension coupling can nevertheless accommodate the application torque.
Industrial SXC Variety
The SXC Variety will be the shut coupled variation in the SX Form coupling. The SXC is just like the SX coupling in the disc packs are connected when the coupling is put in. Inside the close coupled units, the hubs are turned inward and therefore are mounted within the spacer. Note that with the hubs within the spacer, the utmost bore allowed within the hub are going to be decreased. The SXC couplings is usually applied with 1 or the two hubs turned outward to allow the coupling to accommodate diverse shaft separations.
Industrial SXCS and SXCST Styles
The SXCS and SXCST Sorts have split spacers as well as disc packs might be serviced or eliminated with out moving the hubs over the shafts and without the need of moving the products. The SXCS Type has the bolts that connect the hubs to the split spacer set up through the ends in the couplings. The SXCST possess the bolts set up from within the spacer pointing outward in direction of the hubs.
