Disc Coupling Overview

Industrial SU Form
The SU Form coupling has a single flex plane with two hubs and a single disc pack. It really is ideal for angular and axial misalignment only. Two SU couplings Industrial%20SU%20Typetend to be mixed having a shaft
for making a floating shaft coupling. The shaft can be hollow for lengthy light bodyweight floating shaft couplings.
Industrial SX Sort
This is often the conventional coupling style that incorporates two hubs, a stock length spacer built to meet marketplace common lengths, and two unitized disc packs. The coupling has two flex planes, a single at every disc pack, making it possible for this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is accessible in six and eight bolt models and bore sizes as much as 13 inches (330mm) around the greatest size. Custom spacer lengths can be produced to meet unique shaft separations demanded for precise applications. The SX coupling can be fitted with overload bushings to protect the disc packs in in excess of torque disorders and might act as an anti-flail device. SX couplings are assembled with the time of installation about the products in which the coupling are going to be in services.
Industrial DI Form
The DI Kind coupling includes a “Drop-In” spacer assembly that may be assembled with the factory. The coupling consists of two hubs and 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 in the factory employing the torque values advised by Lovejoy to the disc pack bolts. Together with the hubs mounted on the shafts, the whole disc pack assembly could be “Dropped In” spot concerning the 2 hubs. The hubs are piloted to make sure suitable centering of your spacer assembly. This piloting serves as an anti-flail function and aids from the coupling’s potential to meet the balance standards mandated by API. This style coupling is developed to meet the balance and anti-flail specifications specified in API-610.
Oversized, or Jumbo, hubs can be found for use together with the DI Style coupling to permit for more substantial bore sizes on most DI coupling sizes. This permits for the use of smaller DI couplings in applications where a smaller sized dimension coupling can nevertheless accommodate the application torque.
Industrial SXC Sort
The SXC Type is the near coupled variation of the SX Type coupling. The SXC is much like the SX coupling in the disc packs are attached when the coupling is installed. From the close coupled units, the hubs are turned inward and therefore are mounted within the spacer. Note that with the hubs within the spacer, the maximum bore permitted in the hub is going to be decreased. The SXC couplings can be utilized with one or each hubs turned outward to allow the coupling to accommodate distinctive shaft separations.
Industrial SXCS and SXCST Kinds
The SXCS and SXCST Forms have split spacers along with the disc packs might be serviced or eliminated without moving the hubs within the shafts and devoid of moving the tools. The SXCS Form has the bolts that connect the hubs to the split spacer installed from your ends on the couplings. The SXCST have the bolts put in from within the spacer pointing outward in direction of the hubs.
