Industrial SU Kind
The SU Style coupling includes a single flex plane with two hubs along with a single disc pack. It is ideal for angular and axial misalignment only. Two SU couplings are often mixed by using a shaft
to make a floating shaft coupling. The shaft may be hollow for lengthy light weight floating shaft couplings.
Industrial SX Sort
This is often the normal coupling form that consists of two hubs, a stock length spacer intended to meet industry conventional lengths, and two unitized disc packs. The coupling has two flex planes, 1 at just about every disc pack, permitting this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is available in 6 and 8 bolt styles and bore sizes as much as 13 inches (330mm) over the largest size. Custom spacer lengths could be produced to meet distinctive shaft separations necessary for certain applications. The SX coupling can be 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 at the time of installation on the equipment wherever the coupling are going to be in service.
Industrial DI Sort
The DI Style coupling includes a “Drop-In” spacer assembly that’s assembled at 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 on the factory employing the torque values recommended by Lovejoy for that disc pack bolts. Using the hubs mounted on the shafts, the complete disc pack assembly may be “Dropped In” location between the two hubs. The hubs are piloted to guarantee good centering in the spacer assembly. This piloting serves as an anti-flail characteristic and aids from the coupling’s capability to meet the stability standards mandated by API. This type coupling is designed to meet the balance and anti-flail requirements specified in API-610.
Oversized, or Jumbo, hubs are available for use together with the DI Kind coupling to allow for greater bore sizes on most DI coupling sizes. This enables to the utilization of smaller sized DI couplings in applications wherever a smaller size coupling can nevertheless accommodate the application torque.
Industrial SXC Variety
The SXC Form will be the shut coupled variation in the SX Form coupling. The SXC is much like the SX coupling in the disc packs are connected when the coupling is put in. Inside the near coupled units, the hubs are turned inward and are mounted inside the spacer. Note that using the hubs inside the spacer, the maximum bore allowed from the hub will probably be decreased. The SXC couplings is usually utilized with 1 or each hubs turned outward to allow the coupling to accommodate unique shaft separations.
Industrial SXCS and SXCST Kinds
The SXCS and SXCST Styles have split spacers along with the disc packs could be serviced or removed with no moving the hubs within the shafts and with out moving the tools. The SXCS Form has the bolts that connect the hubs for the split spacer set up from the ends of your couplings. The SXCST have the bolts put in from inside the spacer pointing outward in the direction of the hubs.
