Industrial SU Type
The SU Style coupling features a single flex plane with two hubs in addition to a single disc pack. It really is appropriate for angular and axial misalignment only. Two SU couplings are sometimes combined having a shaft
for making a floating shaft coupling. The shaft may be hollow for prolonged light excess weight floating shaft couplings.
Industrial SX Variety
This is the common coupling style that involves two hubs, a stock length spacer designed to meet marketplace regular lengths, and two unitized disc packs. The coupling has two flex planes, one particular at each disc pack, allowing this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is available in 6 and eight bolt models and bore sizes up to 13 inches (330mm) on the biggest dimension. Customized spacer lengths may be manufactured to meet distinctive shaft separations required for certain applications. The SX coupling might be fitted with overload bushings to guard the disc packs in in excess of torque disorders and will act as an anti-flail gadget. SX couplings are assembled with the time of set up to the products exactly where the coupling might be in support.
Industrial DI Type
The DI Style coupling includes a “Drop-In” spacer assembly that is definitely assembled in the factory. The coupling includes two hubs as well as a spacer assembly comprising in the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted to the spacer and guard rings with the factory utilizing the torque values recommended by Lovejoy for that disc pack bolts. With the hubs mounted around the shafts, the complete disc pack assembly is usually “Dropped In” spot involving the two hubs. The hubs are piloted to make certain suitable centering from the spacer assembly. This piloting serves as an anti-flail characteristic and aids in the coupling’s potential to meet the stability standards mandated by API. This type coupling is built to meet the stability and anti-flail requirements specified in API-610.
Oversized, or Jumbo, hubs are available for use with all the DI Kind coupling to allow for greater bore sizes on most DI coupling sizes. This enables to the use of smaller DI couplings in applications in which a smaller dimension coupling can still accommodate the application torque.
Industrial SXC Form
The SXC Kind would be the close coupled variation in the SX Form coupling. The SXC is just like the SX coupling in the disc packs are attached when the coupling is installed. Within the close coupled units, the hubs are turned inward and therefore are mounted within the spacer. Note that together with the hubs within the spacer, the maximum bore permitted in the hub will probably be decreased. The SXC couplings may be used with a single or both hubs turned outward to permit the coupling to accommodate distinct shaft separations.
Industrial SXCS and SXCST Varieties
The SXCS and SXCST Types have split spacers along with the disc packs may be serviced or removed without having moving the hubs about the shafts and with out moving the gear. The SXCS Type has the bolts that connect the hubs on the split spacer installed from your ends of your couplings. The SXCST have the bolts put in from inside the spacer pointing outward in direction of the hubs.
