Disc Coupling Overview

Industrial SU Variety
The SU Variety coupling features a single flex plane with two hubs as well as a single disc pack. It is actually suitable for angular and axial misalignment only. Two SU couplings are often mixed using a shaft
to produce a floating shaft coupling. The shaft is usually hollow for lengthy light bodyweight floating shaft couplings.
Industrial SX Form
This is often the normal coupling variety that contains two hubs, a stock length spacer designed to meet marketplace standard lengths, and two unitized disc packs. The coupling has two flex planes, one at every single disc pack, permitting this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is accessible in 6 and 8 bolt models and bore sizes up to 13 inches (330mm) about the biggest dimension. Customized spacer lengths may be produced to meet special shaft separations demanded for unique applications. The SX coupling can be fitted with overload bushings to guard the disc packs in above torque conditions and will act as an anti-flail device. SX couplings are assembled on the time of installation on the equipment the place the coupling will be in service.
Industrial DI Kind
The DI Type coupling includes a “Drop-In” spacer assembly that may be assembled with the factory. The coupling includes two hubs in addition to a spacer assembly comprising in the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted for the spacer and guard rings on the factory utilizing the torque values advisable by Lovejoy to the disc pack bolts. Together with the hubs mounted over the shafts, the complete disc pack assembly is often “Dropped In” location amongst the two hubs. The hubs are piloted to ensure right centering with the spacer assembly. This piloting serves as an anti-flail feature and aids from the coupling’s means to meet the balance standards mandated by API. This design coupling is built to meet the balance and anti-flail needs specified in API-610.
Oversized, or Jumbo, hubs can be found for use with the DI Sort coupling to permit for bigger bore sizes on most DI coupling sizes. This permits for your utilization of smaller DI couplings in applications the place a smaller sized dimension coupling can still accommodate the application torque.
Industrial SXC Style
The SXC Kind is definitely the close coupled variation from the SX Kind coupling. The SXC is much like the SX coupling in the disc packs are attached when the coupling is installed. Inside the shut coupled units, the hubs are turned inward and therefore are mounted inside the spacer. Note that using the hubs within the spacer, the maximum bore allowed while in the hub will likely be decreased. The SXC couplings can be made use of with one particular or the two hubs turned outward to allow the coupling to accommodate unique shaft separations.
Industrial SXCS and SXCST Styles
The SXCS and SXCST Types have split spacers and also the disc packs is usually serviced or eliminated without moving the hubs over the shafts and without moving the products. The SXCS Kind has the bolts that connect the hubs to your split spacer set up in the ends of the couplings. The SXCST possess the bolts installed from inside the spacer pointing outward in direction of the hubs.
