Industrial SU Style
The SU Type coupling includes a single flex plane with two hubs in addition to a single disc pack. It can be suitable for angular and axial misalignment only. Two SU couplings are often combined having a shaft
to create a floating shaft coupling. The shaft could be hollow for lengthy light bodyweight floating shaft couplings.
Industrial SX Style
This is often the normal coupling sort that involves two hubs, a stock length spacer designed to meet marketplace regular 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 obtainable in six and eight bolt styles and bore sizes up to 13 inches (330mm) on the largest size. Customized spacer lengths is often produced to meet specific shaft separations required for precise applications. The SX coupling can be fitted with overload bushings to protect the disc packs in over torque conditions and might act as an anti-flail device. SX couplings are assembled on the time of installation around the equipment in which the coupling will probably be in service.
Industrial DI Sort
The DI Variety coupling has a “Drop-In” spacer assembly that’s assembled with the factory. The coupling includes two hubs along with a spacer assembly comprising on the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted to your spacer and guard rings at the factory working with the torque values recommended by Lovejoy for that disc pack bolts. Together with the hubs mounted within the shafts, the entire disc pack assembly may be “Dropped In” place among the two hubs. The hubs are piloted to be sure correct centering with the spacer assembly. This piloting serves as an anti-flail attribute and aids from the coupling’s means to meet the balance standards mandated by API. This design coupling is intended to meet the stability and anti-flail requirements specified in API-610.
Oversized, or Jumbo, hubs are available for use with all the DI Style coupling to allow for greater bore sizes on most DI coupling sizes. This permits for that utilization of smaller DI couplings in applications in which a smaller size coupling can nevertheless accommodate the application torque.
Industrial SXC Kind
The SXC Type will be the shut coupled variation of the SX Type coupling. The SXC is much like the SX coupling in that the disc packs are connected when the coupling is put in. In the shut coupled units, the hubs are turned inward and therefore are mounted inside the spacer. Note that using the hubs within the spacer, the maximum bore allowed from the hub are going to be decreased. The SXC couplings may be utilised with 1 or both hubs turned outward to permit the coupling to accommodate distinctive shaft separations.
Industrial SXCS and SXCST Styles
The SXCS and SXCST Varieties have split spacers and the disc packs could be serviced or removed with out moving the hubs to the shafts and with out moving the gear. The SXCS Sort has the bolts that connect the hubs on the split spacer put in from the ends on the couplings. The SXCST have the bolts put in from within the spacer pointing outward towards the hubs.
