Disc Coupling Overview

Industrial SU Sort
The SU Form coupling features a single flex plane with two hubs plus a single disc pack. It really is ideal for angular and axial misalignment only. Two SU couplings are frequently combined with a shaft
to generate a floating shaft coupling. The shaft could be hollow for prolonged light bodyweight floating shaft couplings.
Industrial SX Variety
This is certainly the conventional coupling variety that involves two hubs, a stock length spacer created to meet market conventional lengths, and two unitized disc packs. The coupling has two flex planes, one at every disc pack, making it possible for this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is available in six and 8 bolt types and bore sizes as much as 13 inches (330mm) to the biggest dimension. Customized spacer lengths is often manufactured to meet distinctive shaft separations required for particular applications. The SX coupling may be fitted with overload bushings to guard the disc packs in above torque ailments and can act as an anti-flail device. SX couplings are assembled in the time of set up within the equipment exactly where the coupling are going to be in service.
Industrial DI Sort
The DI Variety coupling features a “Drop-In” spacer assembly that is assembled with the factory. The coupling includes two hubs in addition to a spacer assembly comprising of your spacer, two unitized disc packs, and two guard rings. The disc packs are bolted on the spacer and guard rings on the factory working with the torque values suggested by Lovejoy for that disc pack bolts. With all the hubs mounted to the shafts, the complete disc pack assembly is usually “Dropped In” area in between the 2 hubs. The hubs are piloted to make certain proper centering of the spacer assembly. This piloting serves as an anti-flail attribute and aids within the coupling’s ability to meet the stability standards mandated by API. This fashion coupling is built to meet the stability and anti-flail necessities specified in API-610.
Oversized, or Jumbo, hubs are available for use together with the DI Sort coupling to permit for more substantial bore sizes on most DI coupling sizes. This enables for that utilization of smaller sized DI couplings in applications exactly where a smaller sized dimension coupling can even now accommodate the application torque.
Industrial SXC Kind
The SXC Type would be the shut coupled variation in the SX Variety coupling. The SXC is much like the SX coupling in the disc packs are connected when the coupling is set up. While in the shut coupled units, the hubs are turned inward and therefore are mounted within the spacer. Note that using the hubs within the spacer, the utmost bore allowed from the hub is going to be decreased. The SXC couplings could be used with one or both hubs turned outward to allow the coupling to accommodate various shaft separations.
Industrial SXCS and SXCST Types
The SXCS and SXCST Styles have split spacers and the disc packs might be serviced or eliminated without the need of moving the hubs on the shafts and with out moving the gear. The SXCS Type has the bolts that connect the hubs for the split spacer put in from your ends in the couplings. The SXCST have the bolts installed from within the spacer pointing outward towards the hubs.
