Industrial SU Style
The SU Type coupling includes a single flex plane with two hubs plus a single disc pack. It is actually suitable for angular and axial misalignment only. Two SU couplings are frequently mixed which has a shaft
to generate a floating shaft coupling. The shaft may be hollow for lengthy light excess weight floating shaft couplings.
Industrial SX Sort
That is the regular coupling type that consists of two hubs, a stock length spacer intended to meet industry standard lengths, and two unitized disc packs. The coupling has two flex planes, 1 at each and every disc pack, permitting this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is available in six and 8 bolt models and bore sizes as much as 13 inches (330mm) around the biggest dimension. Custom spacer lengths could be produced to meet distinctive shaft separations needed for distinct applications. The SX coupling may be fitted with overload bushings to safeguard the disc packs in above torque disorders and will act as an anti-flail device. SX couplings are assembled at the time of installation around the gear the place the coupling will probably be in services.
Industrial DI Sort
The DI Form coupling features a “Drop-In” spacer assembly that is assembled on the factory. The coupling includes two hubs and also a spacer assembly comprising with the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted to your spacer and guard rings in the factory employing the torque values recommended by Lovejoy for that disc pack bolts. Together with the hubs mounted within the shafts, the entire disc pack assembly is usually “Dropped In” area amongst the 2 hubs. The hubs are piloted to ensure correct centering of your spacer assembly. This piloting serves as an anti-flail characteristic and aids from the coupling’s skill to meet the stability specifications mandated by API. This fashion coupling is created to meet the stability and anti-flail requirements specified in API-610.
Oversized, or Jumbo, hubs are available for use using the DI Form coupling to permit for more substantial bore sizes on most DI coupling sizes. This enables for the use of smaller DI couplings in applications wherever a smaller sized dimension coupling can still accommodate the application torque.
Industrial SXC Variety
The SXC Form is definitely the shut coupled variation on the SX Form coupling. The SXC is similar to the SX coupling in that the disc packs are connected once the coupling is installed. From the close coupled units, the hubs are turned inward and therefore are mounted inside the spacer. Note that with all the hubs inside the spacer, the utmost bore permitted from the hub will be decreased. The SXC couplings is often used with one particular or both hubs turned outward to allow the coupling to accommodate different shaft separations.
Industrial SXCS and SXCST Kinds
The SXCS and SXCST Sorts have split spacers as well as disc packs can be serviced or removed with out moving the hubs to the shafts and with no moving the equipment. The SXCS Kind has the bolts that connect the hubs to your split spacer put in in the ends in the couplings. The SXCST have the bolts put in from within the spacer pointing outward in direction of the hubs.
