Disc Coupling Overview

Industrial SU Form
The SU Sort coupling features a single flex plane with two hubs along with a single disc pack. It truly is appropriate for angular and axial misalignment only. Two SU couplings are often mixed which has a shaft
to make a floating shaft coupling. The shaft is usually hollow for long light excess weight floating shaft couplings.
Industrial SX Variety
This is often the conventional coupling type that contains two hubs, a stock length spacer developed to meet marketplace standard lengths, and two unitized disc packs. The coupling has two flex planes, a single at just about every disc pack, allowing this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is accessible in 6 and eight bolt types and bore sizes as much as 13 inches (330mm) about the greatest size. Custom spacer lengths could be manufactured to meet specific shaft separations needed for distinct applications. The SX coupling is often 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 with the time of set up about the products the place the coupling is going to be in support.
Industrial DI Type
The DI Form coupling includes a “Drop-In” spacer assembly which is assembled at the factory. The coupling includes two hubs along with a spacer assembly comprising in the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted on the spacer and guard rings in the factory working with the torque values advised by Lovejoy for your disc pack bolts. Together with the hubs mounted to the shafts, the complete disc pack assembly might be “Dropped In” area concerning the two hubs. The hubs are piloted to be sure correct centering in the spacer assembly. This piloting serves as an anti-flail function and aids inside the coupling’s potential to meet the stability standards mandated by API. This fashion coupling is created to meet the stability and anti-flail demands specified in API-610.
Oversized, or Jumbo, hubs are available for use using the DI Form coupling to allow for greater bore sizes on most DI coupling sizes. This enables for the utilization of smaller sized DI couplings in applications where a smaller sized size coupling can even now accommodate the application torque.
Industrial SXC Variety
The SXC Form may be the near coupled variation on the SX Style coupling. The SXC is just like the SX coupling in that the disc packs are connected when the coupling is set up. While in the close coupled units, the hubs are turned inward and therefore are mounted within the spacer. Note that using the hubs within the spacer, the utmost bore allowed inside the hub might be decreased. The SXC couplings can be applied with a single or both hubs turned outward to permit the coupling to accommodate distinct shaft separations.
Industrial SXCS and SXCST Types
The SXCS and SXCST Forms have split spacers and the disc packs is often serviced or eliminated with out moving the hubs to the shafts and without moving the products. The SXCS Kind has the bolts that connect the hubs towards the split spacer set up from the ends on the couplings. The SXCST have the bolts installed from within the spacer pointing outward in direction of the hubs.
