Industrial SU Sort
The SU Style coupling features a single flex plane with two hubs and also a single disc pack. It is actually ideal for angular and axial misalignment only. Two SU couplings are often combined using a shaft
for making a floating shaft coupling. The shaft is usually hollow for long light excess weight floating shaft couplings.
Industrial SX Type
This is certainly the conventional coupling variety that involves two hubs, a stock length spacer designed to meet business standard lengths, and two unitized disc packs. The coupling has two flex planes, a single at each and every disc pack, enabling this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is accessible in six and 8 bolt styles and bore sizes up to 13 inches (330mm) over the biggest size. Customized spacer lengths might be produced to meet particular shaft separations demanded for distinct applications. The SX coupling can be fitted with overload bushings to safeguard the disc packs in above torque situations and will act as an anti-flail gadget. SX couplings are assembled on the time of set up over the tools the place the coupling will likely be in service.
Industrial DI Variety
The DI Type coupling features a “Drop-In” spacer assembly that is certainly assembled in 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 to your spacer and guard rings on the factory employing the torque values advisable by Lovejoy for that disc pack bolts. Together with the hubs mounted around the shafts, the whole disc pack assembly can be “Dropped In” place between the two hubs. The hubs are piloted to make certain right centering of the spacer assembly. This piloting serves as an anti-flail feature and aids inside the coupling’s potential to meet the balance standards mandated by API. This fashion coupling is intended to meet the balance and anti-flail needs specified in API-610.
Oversized, or Jumbo, hubs are available for use with the DI Form coupling to permit for more substantial bore sizes on most DI coupling sizes. This permits for that utilization of smaller sized DI couplings in applications the place a smaller dimension coupling can nevertheless accommodate the application torque.
Industrial SXC Form
The SXC Style is definitely the shut coupled variation from the SX Variety coupling. The SXC is much like the SX coupling in that the disc packs are connected once the coupling is installed. From the shut 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 allowed during the hub will likely be decreased. The SXC couplings could be made use of with a single or the two hubs turned outward to permit the coupling to accommodate unique shaft separations.
Industrial SXCS and SXCST Kinds
The SXCS and SXCST Forms have split spacers as well as disc packs is often serviced or removed without moving the hubs about the shafts and without the need of moving the gear. The SXCS Kind has the bolts that connect the hubs towards the split spacer set up through the ends of the couplings. The SXCST have the bolts installed from inside the spacer pointing outward in direction of the hubs.
