Disc Coupling Overview

Industrial SU Variety
The SU Kind coupling features a single flex plane with two hubs plus a single disc pack. It is actually appropriate for angular and axial misalignment only. Two SU couplings tend to be mixed using a shaft
to produce a floating shaft coupling. The shaft could be hollow for prolonged light excess weight floating shaft couplings.
Industrial SX Style
This is often the common coupling sort that involves two hubs, a stock length spacer made to meet market typical lengths, and two unitized disc packs. The coupling has two flex planes, one particular at each and every disc pack, enabling 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) to the largest dimension. Custom spacer lengths might be produced to meet specific shaft separations necessary for certain applications. The SX coupling is often fitted with overload bushings to safeguard the disc packs in over torque ailments and can act as an anti-flail device. SX couplings are assembled at the time of installation about the tools where the coupling will be in service.
Industrial DI Form
The DI Kind coupling includes a “Drop-In” spacer assembly that’s assembled with the factory. The coupling includes two hubs along with a spacer assembly comprising in the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted towards the spacer and guard rings with the factory working with the torque values encouraged by Lovejoy for that disc pack bolts. Together with the hubs mounted about the shafts, the whole disc pack assembly might be “Dropped In” place involving the two hubs. The hubs are piloted to be sure right centering with the spacer assembly. This piloting serves as an anti-flail characteristic and aids in the coupling’s skill to meet the balance specifications mandated by API. This type coupling is intended to meet the balance and anti-flail prerequisites specified in API-610.
Oversized, or Jumbo, hubs can be found for use together with the DI Kind coupling to permit for more substantial bore sizes on most DI coupling sizes. This enables for your utilization of smaller DI couplings in applications in which a smaller sized size coupling can even now accommodate the application torque.
Industrial SXC Variety
The SXC Variety is the shut coupled variation with the SX Form coupling. The SXC is similar to the SX coupling in the disc packs are attached once the coupling is installed. Inside the near coupled units, the hubs are turned inward and therefore are mounted within the spacer. Note that together with the hubs inside the spacer, the maximum bore permitted from the hub is going to be decreased. The SXC couplings may be utilised with one particular or both hubs turned outward to permit the coupling to accommodate diverse shaft separations.
Industrial SXCS and SXCST Kinds
The SXCS and SXCST Styles have split spacers and the disc packs can be serviced or removed with out moving the hubs over the shafts and devoid of moving the products. The SXCS Sort has the bolts that connect the hubs on the split spacer put in from the ends of the couplings. The SXCST have the bolts put in from inside the spacer pointing outward in direction of the hubs.
