Industrial SU Form
The SU Style coupling includes a single flex plane with two hubs along with a single disc pack. It truly is ideal for angular and axial misalignment only. Two SU couplings tend to be mixed by using a shaft
to produce a floating shaft coupling. The shaft can be hollow for long light weight floating shaft couplings.
Industrial SX Kind
This really is the standard coupling style that includes two hubs, a stock length spacer made to meet field typical lengths, and two unitized disc packs. The coupling has two flex planes, one at every disc pack, permitting this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is available in six and eight bolt types and bore sizes up to 13 inches (330mm) on the largest dimension. Custom spacer lengths can be manufactured to meet specific shaft separations required for particular applications. The SX coupling can be fitted with overload bushings to safeguard the disc packs in more than torque ailments and might act as an anti-flail device. SX couplings are assembled with the time of installation over the equipment in which the coupling will be in service.
Industrial DI Type
The DI Sort coupling features a “Drop-In” spacer assembly that may be assembled in the factory. The coupling includes two hubs plus a spacer assembly comprising on the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted on the spacer and guard rings at the factory making use of the torque values encouraged by Lovejoy to the disc pack bolts. With all the hubs mounted around the shafts, the entire disc pack assembly might be “Dropped In” spot in between the 2 hubs. The hubs are piloted to be sure good centering with the spacer assembly. This piloting serves as an anti-flail function and aids while in the coupling’s potential to meet the stability requirements mandated by API. This style coupling is developed to meet the balance and anti-flail prerequisites specified in API-610.
Oversized, or Jumbo, hubs are available for use with the DI Sort coupling to permit for greater bore sizes on most DI coupling sizes. This enables for that use of smaller DI couplings in applications the place a smaller size coupling can even now accommodate the application torque.
Industrial SXC Sort
The SXC Sort could be the shut coupled variation in the SX Variety coupling. The SXC is similar to the SX coupling in that the disc packs are connected once the coupling is installed. While 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 permitted inside the hub might be decreased. The SXC couplings could be made use of with a single or the two hubs turned outward to permit the coupling to accommodate distinctive shaft separations.
Industrial SXCS and SXCST Types
The SXCS and SXCST Varieties have split spacers plus the disc packs is often serviced or eliminated without moving the hubs within the shafts and without having moving the products. The SXCS Style has the bolts that connect the hubs on the split spacer put in from the ends from the couplings. The SXCST have the bolts put in from within the spacer pointing outward in the direction of the hubs.
