Disc Coupling Overview

Industrial SU Type
The SU Sort coupling includes a single flex plane with two hubs as well as a single disc pack. It truly is appropriate for angular and axial misalignment only. Two SU couplings are sometimes combined which has a shaft
to generate a floating shaft coupling. The shaft is often hollow for prolonged light fat floating shaft couplings.
Industrial SX Type
This can be the typical coupling style that incorporates two hubs, a stock length spacer designed to meet sector normal lengths, and two unitized disc packs. The coupling has two flex planes, one particular at each disc pack, enabling this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is obtainable in 6 and 8 bolt designs and bore sizes as much as 13 inches (330mm) about the biggest dimension. Customized spacer lengths could be produced to meet specific shaft separations demanded for certain applications. The SX coupling could be fitted with overload bushings to safeguard the disc packs in above torque problems and may act as an anti-flail gadget. SX couplings are assembled on the time of installation on the tools in which the coupling are going to be in support.
Industrial DI Variety
The DI Form coupling has a “Drop-In” spacer assembly that is definitely assembled on the factory. The coupling consists of two hubs as well as a spacer assembly comprising of your spacer, two unitized disc packs, and two guard rings. The disc packs are bolted to the spacer and guard rings in the factory applying the torque values suggested by Lovejoy for that disc pack bolts. Using the hubs mounted to the shafts, the complete disc pack assembly is often “Dropped In” spot amongst the 2 hubs. The hubs are piloted to guarantee correct centering of your spacer assembly. This piloting serves as an anti-flail feature and aids within the coupling’s capability to meet the balance specifications mandated by API. This design coupling is designed to meet the balance and anti-flail needs specified in API-610.
Oversized, or Jumbo, hubs can be found for use using the DI Type coupling to allow for more substantial bore sizes on most DI coupling sizes. This allows for your utilization of smaller DI couplings in applications where a smaller sized dimension coupling can even now accommodate the application torque.
Industrial SXC Style
The SXC Form would be the shut coupled variation from the SX Form coupling. The SXC is much like the SX coupling in the disc packs are connected once the coupling is put in. Within the shut 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 during the hub will be decreased. The SXC couplings may be made use of with one particular or the two hubs turned outward to allow the coupling to accommodate distinctive shaft separations.
Industrial SXCS and SXCST Varieties
The SXCS and SXCST Sorts have split spacers as well as disc packs might be serviced or eliminated with no moving the hubs to the shafts and with out moving the products. The SXCS Style has the bolts that connect the hubs to your split spacer installed from the ends on the couplings. The SXCST possess the bolts set up from within the spacer pointing outward in the direction of the hubs.
