Industrial SU Kind
The SU Variety coupling includes a single flex plane with two hubs and a single disc pack. It’s appropriate for angular and axial misalignment only. Two SU couplings tend to be mixed with a shaft
to produce a floating shaft coupling. The shaft is usually hollow for lengthy light weight floating shaft couplings.
Industrial SX Style
That is the typical coupling form that involves two hubs, a stock length spacer intended to meet sector normal lengths, and two unitized disc packs. The coupling has two flex planes, a single at each disc pack, permitting this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is accessible in six and eight bolt types and bore sizes as much as 13 inches (330mm) on the biggest size. Customized spacer lengths might be produced to meet special shaft separations essential for precise applications. The SX coupling is usually fitted with overload bushings to protect the disc packs in above torque ailments and might act as an anti-flail device. SX couplings are assembled with the time of installation around the products in which the coupling might be in services.
Industrial DI Variety
The DI Type coupling features a “Drop-In” spacer assembly that is definitely assembled on the factory. The coupling consists of two hubs in addition to a spacer assembly comprising in the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted to your spacer and guard rings in the factory using the torque values recommended by Lovejoy for your disc pack bolts. With all the hubs mounted over the shafts, the entire disc pack assembly can be “Dropped In” place involving the 2 hubs. The hubs are piloted to ensure correct centering with the spacer assembly. This piloting serves as an anti-flail feature and aids within the coupling’s capacity to meet the balance specifications mandated by API. This style coupling is designed 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 Style coupling to allow for greater bore sizes on most DI coupling sizes. This enables for that use of smaller DI couplings in applications wherever a smaller dimension coupling can nevertheless accommodate the application torque.
Industrial SXC Kind
The SXC Style is definitely the near coupled variation of your SX Style coupling. The SXC is similar to the SX coupling in that the disc packs are connected when the coupling is set up. While in the close coupled units, the hubs are turned inward and are mounted within the spacer. Note that with the hubs inside the spacer, the maximum bore permitted during the hub will likely be decreased. The SXC couplings is usually used with one particular or both hubs turned outward to allow the coupling to accommodate distinct shaft separations.
Industrial SXCS and SXCST Types
The SXCS and SXCST Kinds have split spacers as well as the disc packs could be serviced or eliminated without the need of moving the hubs around the shafts and without having moving the gear. The SXCS Variety has the bolts that connect the hubs to the split spacer put in in the ends on the couplings. The SXCST have the bolts installed from within the spacer pointing outward in direction of the hubs.
