Industrial SU Form
The SU Sort coupling features a single flex plane with two hubs and also a single disc pack. It truly is ideal for angular and axial misalignment only. Two SU couplings are often combined by using a shaft
to generate a floating shaft coupling. The shaft is often hollow for lengthy light fat floating shaft couplings.
Industrial SX Sort
This is certainly the normal coupling variety that incorporates two hubs, a stock length spacer designed to meet field normal lengths, and two unitized disc packs. The coupling has two flex planes, 1 at every disc pack, permitting this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is accessible in 6 and 8 bolt designs and bore sizes as much as 13 inches (330mm) around the greatest size. Custom spacer lengths could be manufactured to meet exclusive shaft separations needed for unique applications. The SX coupling might be fitted with overload bushings to guard the disc packs in more than torque problems and may act as an anti-flail device. SX couplings are assembled on the time of set up within the gear where the coupling are going to be in services.
Industrial DI Style
The DI Type coupling features a “Drop-In” spacer assembly that is assembled in the factory. The coupling consists of two hubs along with a spacer assembly comprising with the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted for the spacer and guard rings in the factory utilizing the torque values advisable by Lovejoy to the disc pack bolts. With the hubs mounted within the shafts, the complete disc pack assembly can be “Dropped In” area between the two hubs. The hubs are piloted to make certain good centering of your spacer assembly. This piloting serves as an anti-flail feature and aids within the coupling’s capability to meet the stability standards mandated by API. This fashion coupling is built to meet the balance and anti-flail requirements specified in API-610.
Oversized, or Jumbo, hubs can be found for use with all the DI Form coupling to permit for greater bore sizes on most DI coupling sizes. This permits for your use of smaller DI couplings in applications where a smaller size coupling can nevertheless accommodate the application torque.
Industrial SXC Variety
The SXC Form would be the close coupled variation from the SX Kind coupling. The SXC is just like the SX coupling in the disc packs are connected once the coupling is set up. While in the shut coupled units, the hubs are turned inward and are mounted inside the spacer. Note that with all the hubs inside the spacer, the maximum bore permitted within the hub will be decreased. The SXC couplings is often employed with a single or each hubs turned outward to allow the coupling to accommodate distinctive shaft separations.
Industrial SXCS and SXCST Varieties
The SXCS and SXCST Forms have split spacers along with the disc packs is usually serviced or eliminated with out moving the hubs to the shafts and with out moving the equipment. The SXCS Style has the bolts that connect the hubs towards the split spacer set up through the ends from the couplings. The SXCST have the bolts installed from within the spacer pointing outward in the direction of the hubs.
