Disc Coupling Overview

Industrial SU Variety
The SU Variety coupling features a single flex plane with two hubs and also a single disc pack. It can be suitable for angular and axial misalignment only. Two SU couplings are frequently combined having a shaft
to make a floating shaft coupling. The shaft could be hollow for lengthy light bodyweight floating shaft couplings.
Industrial SX Type
This is the regular coupling sort that consists of two hubs, a stock length spacer built to meet business common lengths, and two unitized disc packs. The coupling has two flex planes, one at every disc pack, permitting this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is available in six and eight bolt models and bore sizes as much as 13 inches (330mm) over the biggest dimension. Customized spacer lengths may be manufactured to meet particular shaft separations expected for unique applications. The SX coupling is usually fitted with overload bushings to safeguard the disc packs in over torque problems and may act as an anti-flail device. SX couplings are assembled on the time of set up on the tools the place the coupling will be in service.
Industrial DI Variety
The DI Style coupling includes a “Drop-In” spacer assembly which is assembled with the factory. The coupling consists of two hubs as well as a spacer assembly comprising of your spacer, two unitized disc packs, and two guard rings. The disc packs are bolted for the spacer and guard rings with the factory employing the torque values advisable by Lovejoy for the disc pack bolts. With all the hubs mounted over the shafts, the complete disc pack assembly can be “Dropped In” place among the 2 hubs. The hubs are piloted to make sure correct centering of the spacer assembly. This piloting serves as an anti-flail function and aids from the coupling’s ability to meet the balance standards mandated by API. This fashion coupling is intended to meet the stability and anti-flail specifications specified in API-610.
Oversized, or Jumbo, hubs are available for use together with the DI Kind coupling to allow for greater bore sizes on most DI coupling sizes. This enables for that use of smaller DI couplings in applications where a smaller dimension coupling can even now accommodate the application torque.
Industrial SXC Style
The SXC Variety could be the shut coupled variation of the SX Type coupling. The SXC is similar to the SX coupling in that the disc packs are connected once the coupling is put in. Inside the close coupled units, the hubs are turned inward and are mounted inside the spacer. Note that with the hubs inside the spacer, the maximum bore allowed during the hub will probably be decreased. The SXC couplings is often applied with one or each hubs turned outward to permit the coupling to accommodate various shaft separations.
Industrial SXCS and SXCST Sorts
The SXCS and SXCST Kinds have split spacers along with the disc packs is usually serviced or removed without the need of moving the hubs around the shafts and without moving the gear. The SXCS Type has the bolts that connect the hubs for the split spacer installed in the ends on the couplings. The SXCST have the bolts put in from inside the spacer pointing outward towards the hubs.
