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 tend to be combined which has a shaft
to generate a floating shaft coupling. The shaft could be hollow for prolonged light bodyweight floating shaft couplings.
Industrial SX Sort
This is certainly the conventional coupling variety that contains 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) about the biggest size. Customized spacer lengths is often manufactured to meet distinctive shaft separations required for particular applications. The SX coupling can be fitted with overload bushings to protect 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 products exactly where the coupling are going to be in service.
Industrial DI Sort
The DI Variety coupling has a “Drop-In” spacer assembly that may be assembled with the factory. The coupling includes two hubs and also 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 in the factory employing the torque values suggested by Lovejoy to the disc pack bolts. Using the hubs mounted to the shafts, the complete disc pack assembly is usually “Dropped In” spot in between the 2 hubs. The hubs are piloted to make sure proper centering of your spacer assembly. This piloting serves as an anti-flail characteristic and aids in the coupling’s means to meet the stability standards mandated by API. This style coupling is built to meet the stability and anti-flail demands 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 where a smaller sized dimension coupling can even now accommodate the application torque.
Industrial SXC Type
The SXC Type may be the shut coupled variation in the SX Sort coupling. The SXC is much like the SX coupling in the disc packs are connected once the coupling is set up. Inside the near 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 made use of with one or both hubs turned outward to allow the coupling to accommodate various shaft separations.
Industrial SXCS and SXCST Styles
The SXCS and SXCST Forms have split spacers as well as disc packs might be serviced or eliminated devoid of moving the hubs on the shafts and without moving the equipment. 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 inside the spacer pointing outward towards the hubs.
