Disc Coupling Overview

Industrial SU Sort
The SU Variety coupling features a single flex plane with two hubs and a single disc pack. It truly is suitable for angular and axial misalignment only. Two SU couplings are often mixed having a shaft
to produce a floating shaft coupling. The shaft may be hollow for lengthy light fat floating shaft couplings.
Industrial SX Sort
That is the normal coupling style that involves two hubs, a stock length spacer developed to meet sector standard lengths, and two unitized disc packs. The coupling has two flex planes, one particular at just about every disc pack, allowing this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is accessible in six and 8 bolt models and bore sizes up to 13 inches (330mm) about the biggest size. Custom spacer lengths is often manufactured to meet special shaft separations needed for specific applications. The SX coupling is often fitted with overload bushings to safeguard the disc packs in in excess of torque disorders and will act as an anti-flail device. SX couplings are assembled on the time of set up around the tools in which the coupling might be in support.
Industrial DI Style
The DI Form coupling has a “Drop-In” spacer assembly that is certainly assembled in the factory. The coupling consists of two hubs and also a spacer assembly comprising with the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted to the spacer and guard rings on the factory applying the torque values recommended by Lovejoy for the disc pack bolts. With all the hubs mounted over the shafts, the whole disc pack assembly could be “Dropped In” area between the two hubs. The hubs are piloted to guarantee correct centering of your spacer assembly. This piloting serves as an anti-flail function and aids from the coupling’s capability to meet the stability specifications mandated by API. This type coupling is designed to meet the stability and anti-flail specifications specified in API-610.
Oversized, or Jumbo, hubs can be found for use with the DI Kind coupling to allow for bigger bore sizes on most DI coupling sizes. This permits for the use of smaller DI couplings in applications in which a smaller sized dimension coupling can nonetheless accommodate the application torque.
Industrial SXC Sort
The SXC Style is the near coupled variation on the SX Sort coupling. The SXC is similar to the SX coupling in the disc packs are connected once the coupling is installed. From the shut coupled units, the hubs are turned inward and are mounted inside the spacer. Note that together with the hubs within the spacer, the maximum bore permitted during the hub might be decreased. The SXC couplings may be made use of with 1 or each hubs turned outward to allow the coupling to accommodate distinctive shaft separations.
Industrial SXCS and SXCST Kinds
The SXCS and SXCST Types have split spacers as well as disc packs can be serviced or removed without moving the hubs on the shafts and devoid of moving the products. The SXCS Kind has the bolts that connect the hubs for the split spacer put in from the ends on the couplings. The SXCST have the bolts put in from inside the spacer pointing outward towards the hubs.
