Industrial SU Sort
The SU Style coupling has a single flex plane with two hubs and also a single disc pack. It’s appropriate for angular and axial misalignment only. Two SU couplings tend to be mixed using a shaft
for making a floating shaft coupling. The shaft might be hollow for extended light fat floating shaft couplings.
Industrial SX Form
This is often the regular coupling variety that involves two hubs, a stock length spacer intended to meet field normal lengths, and two unitized disc packs. The coupling has two flex planes, 1 at just about every disc pack, making it possible for this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is accessible in six and 8 bolt designs and bore sizes as much as 13 inches (330mm) about the biggest size. Custom spacer lengths might be manufactured to meet particular shaft separations essential for unique applications. The SX coupling could be fitted with overload bushings to guard the disc packs in above torque situations and might act as an anti-flail device. SX couplings are assembled with the time of installation on the products the place the coupling will likely be in support.
Industrial DI Variety
The DI Sort coupling includes a “Drop-In” spacer assembly that may be assembled on the factory. The coupling includes two hubs along with a spacer assembly comprising from the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted to your spacer and guard rings with the factory utilizing the torque values encouraged by Lovejoy for the disc pack bolts. Together with the hubs mounted around the shafts, the whole disc pack assembly is often “Dropped In” spot amongst the two hubs. The hubs are piloted to be sure right centering of the spacer assembly. This piloting serves as an anti-flail attribute and aids in the coupling’s ability to meet the balance standards mandated by API. This design coupling is made to meet the balance and anti-flail requirements specified in API-610.
Oversized, or Jumbo, hubs are available for use with all the DI Sort coupling to permit for larger bore sizes on most DI coupling sizes. This permits for that use of smaller DI couplings in applications exactly where a smaller sized dimension coupling can even now accommodate the application torque.
Industrial SXC Form
The SXC Style would be the near coupled variation on the SX Kind coupling. The SXC is just like the SX coupling in that the disc packs are connected once the coupling is put in. From the close coupled units, the hubs are turned inward and therefore are mounted inside the spacer. Note that with the hubs within the spacer, the utmost bore allowed during the hub might be decreased. The SXC couplings can be utilized with one particular or the two hubs turned outward to permit the coupling to accommodate distinct shaft separations.
Industrial SXCS and SXCST Styles
The SXCS and SXCST Kinds have split spacers along with the disc packs is often serviced or removed devoid of moving the hubs about the shafts and with no moving the equipment. The SXCS Style has the bolts that connect the hubs to your split spacer put in from the ends of the couplings. The SXCST have the bolts put in from inside the spacer pointing outward in the direction of the hubs.
