Industrial SU Style
The SU Kind coupling has a single flex plane with two hubs plus a single disc pack. It is appropriate for angular and axial misalignment only. Two SU couplings tend to be combined by using a shaft
for making a floating shaft coupling. The shaft can be hollow for extended light excess weight floating shaft couplings.
Industrial SX Sort
This is often the typical coupling sort that contains two hubs, a stock length spacer designed to meet market common lengths, and two unitized disc packs. The coupling has two flex planes, a single at each and every disc pack, allowing this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is available in 6 and 8 bolt styles and bore sizes as much as 13 inches (330mm) over the largest dimension. Customized spacer lengths is usually manufactured to meet unique shaft separations needed for specific applications. The SX coupling might be fitted with overload bushings to safeguard the disc packs in in excess of torque situations and can act as an anti-flail device. SX couplings are assembled on the time of installation around the gear in which the coupling will be in services.
Industrial DI Style
The DI Style coupling features a “Drop-In” spacer assembly that is certainly assembled with the factory. The coupling consists of two hubs and also a spacer assembly comprising from the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted on the spacer and guard rings at the factory employing the torque values recommended by Lovejoy for your disc pack bolts. With the hubs mounted about the shafts, the entire disc pack assembly might be “Dropped In” location amongst the 2 hubs. The hubs are piloted to make certain right centering of the spacer assembly. This piloting serves as an anti-flail function and aids while in the coupling’s potential to meet the stability standards mandated by API. This style coupling is intended to meet the stability and anti-flail needs specified in API-610.
Oversized, or Jumbo, hubs are available for use together with the DI Type coupling to permit for bigger bore sizes on most DI coupling sizes. This allows for your use of smaller DI couplings in applications where a smaller size coupling can nevertheless accommodate the application torque.
Industrial SXC Kind
The SXC Kind would be the close coupled variation in the SX Kind coupling. The SXC is just like the SX coupling in that the disc packs are connected once the coupling is set up. Within the near coupled units, the hubs are turned inward and are mounted inside the spacer. Note that with all the hubs within the spacer, the maximum bore allowed in the hub will be decreased. The SXC couplings is often made use of with one or each hubs turned outward to allow the coupling to accommodate diverse shaft separations.
Industrial SXCS and SXCST Types
The SXCS and SXCST Varieties have split spacers along with the disc packs could be serviced or removed with out moving the hubs about the shafts and with no moving the products. The SXCS Variety has the bolts that connect the hubs to your split spacer put in through the ends of the couplings. The SXCST have the bolts set up from within the spacer pointing outward in direction of the hubs.
