Disc Coupling Overview

Industrial SU Type
The SU Sort coupling features a single flex plane with two hubs and also a single disc pack. It really is suitable for angular and axial misalignment only. Two SU couplings tend to be combined having a shaft
to create a floating shaft coupling. The shaft is often hollow for prolonged light weight floating shaft couplings.
Industrial SX Variety
This is often the conventional coupling kind that consists of two hubs, a stock length spacer developed to meet industry common lengths, and two unitized disc packs. The coupling has two flex planes, one particular at every single disc pack, permitting this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is available in 6 and eight bolt designs and bore sizes up to 13 inches (330mm) within the biggest size. Custom spacer lengths is often produced to meet particular shaft separations essential for precise applications. The SX coupling may be fitted with overload bushings to safeguard the disc packs in more than torque ailments and can act as an anti-flail gadget. SX couplings are assembled at the time of installation around the tools exactly where the coupling is going to be in services.
Industrial DI Variety
The DI Variety coupling features a “Drop-In” spacer assembly that is definitely assembled at the factory. The coupling consists of two hubs plus a spacer assembly comprising on the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted on the spacer and guard rings at the factory using the torque values encouraged by Lovejoy to the disc pack bolts. Using the hubs mounted within the shafts, the complete disc pack assembly can be “Dropped In” area among the two hubs. The hubs are piloted to make sure correct centering in the spacer assembly. This piloting serves as an anti-flail feature and aids within the coupling’s capacity to meet the stability standards mandated by API. This style coupling is made to meet the balance and anti-flail needs specified in API-610.
Oversized, or Jumbo, hubs are available for use with all the DI Kind coupling to permit for more substantial bore sizes on most DI coupling sizes. This enables for the utilization of smaller DI couplings in applications exactly where a smaller sized dimension coupling can nonetheless accommodate the application torque.
Industrial SXC Sort
The SXC Type is the shut coupled variation of your SX Type coupling. The SXC is much like the SX coupling in the disc packs are connected when the coupling is set up. While in the near coupled units, the hubs are turned inward and are mounted inside the spacer. Note that with all the hubs within the spacer, the utmost bore permitted during the hub are going to be decreased. The SXC couplings is usually used with 1 or each hubs turned outward to permit the coupling to accommodate distinctive shaft separations.
Industrial SXCS and SXCST Types
The SXCS and SXCST Sorts have split spacers and also the disc packs is often serviced or removed devoid of moving the hubs to the shafts and with out moving the gear. The SXCS Type has the bolts that connect the hubs on the split spacer set up from your ends on the couplings. The SXCST possess the bolts set up from inside the spacer pointing outward in the direction of the hubs.
