Industrial SU Variety
The SU Variety coupling has a single flex plane with two hubs along with a single disc pack. It is actually appropriate for angular and axial misalignment only. Two SU couplings are frequently mixed using a shaft
to produce a floating shaft coupling. The shaft may be hollow for long light excess weight floating shaft couplings.
Industrial SX Style
This can be the standard coupling sort that contains two hubs, a stock length spacer made to meet market conventional lengths, and two unitized disc packs. The coupling has two flex planes, 1 at each disc pack, enabling this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is accessible in 6 and eight bolt types and bore sizes up to 13 inches (330mm) to the greatest dimension. Customized spacer lengths may be manufactured to meet specific shaft separations required for particular applications. The SX coupling might be fitted with overload bushings to protect the disc packs in above torque circumstances and may act as an anti-flail gadget. SX couplings are assembled on the time of set up within the products the place the coupling will be in services.
Industrial DI Type
The DI Type coupling has a “Drop-In” spacer assembly that’s assembled in the factory. The coupling includes two hubs and a spacer assembly comprising of the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted towards the spacer and guard rings in the factory making use of the torque values proposed by Lovejoy for the disc pack bolts. With all the hubs mounted over the shafts, the whole disc pack assembly may be “Dropped In” place amongst the 2 hubs. The hubs are piloted to guarantee right centering of your spacer assembly. This piloting serves as an anti-flail characteristic and aids inside the coupling’s potential to meet the balance requirements mandated by API. This fashion coupling is intended to meet the stability and anti-flail prerequisites specified in API-610.
Oversized, or Jumbo, hubs can be found for use with the DI Sort coupling to allow for larger bore sizes on most DI coupling sizes. This permits to the use of smaller sized DI couplings in applications the place a smaller size coupling can nevertheless accommodate the application torque.
Industrial SXC Style
The SXC Variety may be the shut coupled variation from 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. In the near coupled units, the hubs are turned inward and therefore are mounted within the spacer. Note that with the hubs inside the spacer, the maximum bore permitted inside the hub will probably be decreased. The SXC couplings can be employed with a single or the two hubs turned outward to allow the coupling to accommodate different shaft separations.
Industrial SXCS and SXCST Kinds
The SXCS and SXCST Forms have split spacers plus the disc packs may be serviced or removed without the need of moving the hubs around the shafts and without having moving the tools. The SXCS Sort has the bolts that connect the hubs to your split spacer installed from the ends of the couplings. The SXCST have the bolts set up from within the spacer pointing outward in direction of the hubs.
