Industrial SU Form
The SU Style coupling has a single flex plane with two hubs and also a single disc pack. It is ideal for angular and axial misalignment only. Two SU couplings are sometimes combined having a shaft
to make a floating shaft coupling. The shaft can be hollow for lengthy light excess weight floating shaft couplings.
Industrial SX Form
This really is the typical coupling form that involves two hubs, a stock length spacer built to meet industry regular lengths, and two unitized disc packs. The coupling has two flex planes, a single at every single disc pack, making it possible for 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) about the largest dimension. Customized spacer lengths may be manufactured to meet particular shaft separations necessary for distinct applications. The SX coupling may be fitted with overload bushings to protect the disc packs in more than torque disorders and can act as an anti-flail device. SX couplings are assembled in the time of installation about the gear wherever the coupling will be in support.
Industrial DI Form
The DI Sort coupling features a “Drop-In” spacer assembly that is definitely assembled in the factory. The coupling consists of two hubs and also a spacer assembly comprising of your spacer, two unitized disc packs, and two guard rings. The disc packs are bolted towards the spacer and guard rings on the factory utilizing the torque values recommended by Lovejoy to the disc pack bolts. Together with the hubs mounted over the shafts, the whole disc pack assembly can be “Dropped In” location in between the two hubs. The hubs are piloted to be sure correct centering on the spacer assembly. This piloting serves as an anti-flail function and aids from the coupling’s skill to meet the balance requirements mandated by API. This style 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 Type coupling to permit for more substantial bore sizes on most DI coupling sizes. This enables for your utilization of smaller sized DI couplings in applications in which a smaller sized size coupling can still accommodate the application torque.
Industrial SXC Type
The SXC Variety could be the shut coupled variation with the SX Style coupling. The SXC is similar to the SX coupling in that the disc packs are connected when the coupling is set up. Inside the shut coupled units, the hubs are turned inward and therefore are mounted within the spacer. Note that with all the hubs inside the spacer, the maximum bore allowed in the hub is going to be decreased. The SXC couplings is often used with a single or the two hubs turned outward to permit the coupling to accommodate distinctive shaft separations.
Industrial SXCS and SXCST Sorts
The SXCS and SXCST Styles have split spacers as well as the disc packs could be serviced or eliminated without moving the hubs around the shafts and devoid of moving the equipment. The SXCS Form has the bolts that connect the hubs towards the split spacer set up from the ends on the couplings. The SXCST possess the bolts put in from inside the spacer pointing outward in direction of the hubs.
