Disc Coupling Overview

Industrial SU Kind
The SU Sort coupling features a single flex plane with two hubs plus a single disc pack. It is appropriate for angular and axial misalignment only. Two SU couplings are sometimes combined by using a shaft
to produce a floating shaft coupling. The shaft may be hollow for prolonged light weight floating shaft couplings.
Industrial SX Type
This is often the standard coupling form that involves two hubs, a stock length spacer intended to meet market common lengths, and two unitized disc packs. The coupling has two flex planes, a single at just about 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) around the greatest dimension. Custom spacer lengths is usually produced to meet unique shaft separations necessary for precise applications. The SX coupling can be fitted with overload bushings to safeguard the disc packs in above torque conditions and might act as an anti-flail device. SX couplings are assembled at the time of set up on the tools wherever the coupling will probably be in support.
Industrial DI Type
The DI Style coupling has a “Drop-In” spacer assembly that’s assembled on the factory. The coupling consists of two hubs plus 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 on the factory applying the torque values recommended by Lovejoy to the disc pack bolts. Using the hubs mounted about the shafts, the complete disc pack assembly is usually “Dropped In” location among the two hubs. The hubs are piloted to make certain suitable centering with the spacer assembly. This piloting serves as an anti-flail characteristic and aids in the coupling’s capability to meet the balance standards mandated by API. This fashion coupling is built to meet the stability and anti-flail requirements specified in API-610.
Oversized, or Jumbo, hubs can be found for use together with the DI Style coupling to allow for bigger bore sizes on most DI coupling sizes. This enables for the utilization of smaller sized DI couplings in applications wherever a smaller sized size coupling can still accommodate the application torque.
Industrial SXC Variety
The SXC Kind will be the near coupled variation in the SX Type coupling. The SXC is much like the SX coupling in the disc packs are connected when the coupling is set up. From the near coupled units, the hubs are turned inward and therefore are mounted inside the spacer. Note that together with the hubs inside the spacer, the utmost bore allowed inside the hub will probably be decreased. The SXC couplings might be utilized with a single or each hubs turned outward to permit the coupling to accommodate unique shaft separations.
Industrial SXCS and SXCST Sorts
The SXCS and SXCST Styles have split spacers and also the disc packs could be serviced or eliminated with no moving the hubs to the shafts and with out moving the equipment. The SXCS Form has the bolts that connect the hubs on the split spacer set up from your ends of your couplings. The SXCST have the bolts put in from inside the spacer pointing outward in the direction of the hubs.
