Disc Coupling Overview

Industrial SU Kind
The SU Type coupling includes a single flex plane with two hubs along with a single disc pack. It can be ideal for angular and axial misalignment only. Two SU couplings are often mixed having a shaft
for making a floating shaft coupling. The shaft can be hollow for extended light weight floating shaft couplings.
Industrial SX Kind
This is the normal coupling sort that incorporates two hubs, a stock length spacer developed to meet marketplace common lengths, and two unitized disc packs. The coupling has two flex planes, a single at every single disc pack, allowing this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is accessible in six and eight bolt types and bore sizes up to 13 inches (330mm) on the biggest dimension. Custom spacer lengths is often produced to meet distinctive shaft separations expected for certain applications. The SX coupling might be fitted with overload bushings to guard the disc packs in above torque problems and can act as an anti-flail device. SX couplings are assembled in the time of set up on the equipment in which the coupling is going to be in services.
Industrial DI Sort
The DI Style coupling has a “Drop-In” spacer assembly that is assembled on the factory. The coupling consists of two hubs as well as a spacer assembly comprising with the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted towards the spacer and guard rings in the factory working with the torque values advisable by Lovejoy for your disc pack bolts. With all the hubs mounted on the shafts, the entire disc pack assembly might be “Dropped In” area between the 2 hubs. The hubs are piloted to guarantee suitable centering of your spacer assembly. This piloting serves as an anti-flail function and aids during the coupling’s capacity to meet the stability requirements mandated by API. This type coupling is created to meet the stability and anti-flail demands 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 permits for that utilization of smaller DI couplings in applications in which a smaller dimension coupling can even now accommodate the application torque.
Industrial SXC Variety
The SXC Form is the close coupled variation of the SX Form 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 inside the spacer. Note that using the hubs within the spacer, the utmost bore permitted inside the hub are going to be decreased. The SXC couplings might be used with one or the two hubs turned outward to allow the coupling to accommodate distinctive shaft separations.
Industrial SXCS and SXCST Forms
The SXCS and SXCST Sorts have split spacers plus the disc packs is usually serviced or eliminated with no moving the hubs within the shafts and without having moving the products. The SXCS Type has the bolts that connect the hubs towards the split spacer put in from the ends of your couplings. The SXCST have the bolts set up from within the spacer pointing outward in the direction of the hubs.
