Industrial SU Kind
The SU Style coupling features a single flex plane with two hubs plus a single disc pack. It’s ideal for angular and axial misalignment only. Two SU couplings are frequently combined by using a shaft
to generate a floating shaft coupling. The shaft could be hollow for lengthy light weight floating shaft couplings.
Industrial SX Style
This can be the conventional coupling type that contains two hubs, a stock length spacer designed to meet market standard lengths, and two unitized disc packs. The coupling has two flex planes, one at every single disc pack, permitting this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is accessible in 6 and eight bolt types and bore sizes up to 13 inches (330mm) within the greatest size. Customized spacer lengths may be manufactured to meet specific shaft separations demanded for unique applications. The SX coupling may be fitted with overload bushings to guard the disc packs in more than torque ailments and can act as an anti-flail device. SX couplings are assembled with the time of installation on the products in which the coupling might be in support.
Industrial DI Form
The DI Form coupling features a “Drop-In” spacer assembly which is assembled on the factory. The coupling consists of two hubs as well as a spacer assembly comprising from the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted on the spacer and guard rings on the factory working with the torque values advisable by Lovejoy for the disc pack bolts. Using the hubs mounted around the shafts, the complete disc pack assembly might be “Dropped In” spot between the 2 hubs. The hubs are piloted to be sure good centering of the spacer assembly. This piloting serves as an anti-flail characteristic and aids from the coupling’s potential to meet the balance specifications mandated by API. This style coupling is developed to meet the stability and anti-flail needs specified in API-610.
Oversized, or Jumbo, hubs can be found for use using the DI Variety coupling to allow for greater bore sizes on most DI coupling sizes. This permits to the utilization of smaller sized DI couplings in applications exactly where a smaller sized size coupling can still accommodate the application torque.
Industrial SXC Type
The SXC Kind would be the shut coupled variation from the SX Type coupling. The SXC is similar to the SX coupling in the disc packs are connected when the coupling is installed. From the close coupled units, the hubs are turned inward and are mounted inside the spacer. Note that with the hubs within the spacer, the maximum bore allowed in the hub will be decreased. The SXC couplings might be applied with one particular or each hubs turned outward to permit the coupling to accommodate diverse shaft separations.
Industrial SXCS and SXCST Styles
The SXCS and SXCST Types have split spacers and the disc packs is usually serviced or removed devoid of moving the hubs about the shafts and with out moving the products. The SXCS Style has the bolts that connect the hubs towards the split spacer put in through the ends from the couplings. The SXCST have the bolts put in from inside the spacer pointing outward in the direction of the hubs.
