Industrial SU Style
The SU Type coupling has a single flex plane with two hubs along with a single disc pack. It really is ideal for angular and axial misalignment only. Two SU couplings are frequently combined having a shaft
to create a floating shaft coupling. The shaft is often hollow for lengthy light weight floating shaft couplings.
Industrial SX Kind
This is often the standard coupling sort that contains two hubs, a stock length spacer created to meet industry conventional lengths, and two unitized disc packs. The coupling has two flex planes, one particular 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 obtainable in six and eight bolt styles and bore sizes as much as 13 inches (330mm) about the greatest dimension. Customized spacer lengths is often manufactured to meet exclusive shaft separations necessary for specific applications. The SX coupling can be fitted with overload bushings to safeguard the disc packs in over torque conditions and will act as an anti-flail device. SX couplings are assembled in the time of set up over the tools in which the coupling are going to be in services.
Industrial DI Variety
The DI Style coupling features a “Drop-In” spacer assembly that may be assembled on the factory. The coupling includes two hubs along with a spacer assembly comprising of your 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 recommended by Lovejoy to the disc pack bolts. Together with the hubs mounted within the shafts, the whole disc pack assembly could be “Dropped In” spot involving the two hubs. The hubs are piloted to make certain suitable centering with the spacer assembly. This piloting serves as an anti-flail attribute and aids from the coupling’s capacity to meet the stability specifications mandated by API. This fashion coupling is intended to meet the stability and anti-flail needs specified in API-610.
Oversized, or Jumbo, hubs are available for use with the DI Kind coupling to allow for bigger bore sizes on most DI coupling sizes. This allows for that use of smaller sized DI couplings in applications wherever a smaller sized size coupling can still accommodate the application torque.
Industrial SXC Kind
The SXC Type would be the shut coupled variation with the SX Sort coupling. The SXC is similar to the SX coupling in that the disc packs are connected when the coupling is installed. Inside the near coupled units, the hubs are turned inward and are mounted inside the spacer. Note that with the hubs within the spacer, the maximum bore permitted from the hub will probably be decreased. The SXC couplings is usually utilized with one particular or both hubs turned outward to permit the coupling to accommodate different shaft separations.
Industrial SXCS and SXCST Kinds
The SXCS and SXCST Types have split spacers as well as the disc packs could be serviced or eliminated with out moving the hubs to the shafts and with no moving the tools. The SXCS Form has the bolts that connect the hubs to the split spacer set up through the ends on the couplings. The SXCST possess the bolts installed from inside the spacer pointing outward in the direction of the hubs.
