Industrial SU Form
The SU Style coupling includes a single flex plane with two hubs as well as a single disc pack. It is actually appropriate for angular and axial misalignment only. Two SU couplings tend to be mixed by using a shaft
for making a floating shaft coupling. The shaft might be hollow for extended light weight floating shaft couplings.
Industrial SX Form
This is often the conventional coupling kind that includes two hubs, a stock length spacer made to meet field normal lengths, and two unitized disc packs. The coupling has two flex planes, 1 at every disc pack, permitting this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is obtainable in 6 and 8 bolt styles and bore sizes up to 13 inches (330mm) over the greatest size. Custom spacer lengths can be manufactured to meet specific shaft separations essential for certain applications. The SX coupling can be fitted with overload bushings to protect the disc packs in over torque circumstances and may act as an anti-flail gadget. SX couplings are assembled with the time of installation about the products wherever the coupling will be in service.
Industrial DI Kind
The DI Type coupling features a “Drop-In” spacer assembly that may be assembled with the factory. The coupling consists of two hubs and a spacer assembly comprising of the spacer, two unitized disc packs, and two guard rings. The disc packs are bolted for the spacer and guard rings at the factory utilizing the torque values advised by Lovejoy for your disc pack bolts. With the hubs mounted around the shafts, the complete disc pack assembly is often “Dropped In” location among the 2 hubs. The hubs are piloted to make sure suitable centering from the spacer assembly. This piloting serves as an anti-flail characteristic and aids in the coupling’s potential to meet the balance standards mandated by API. This style coupling is made to meet the balance and anti-flail demands specified in API-610.
Oversized, or Jumbo, hubs are available for use with all the DI Variety coupling to permit for more substantial bore sizes on most DI coupling sizes. This allows for your utilization of smaller sized DI couplings in applications the place a smaller size coupling can nevertheless accommodate the application torque.
Industrial SXC Form
The SXC Kind may be the shut coupled variation of your SX Form coupling. The SXC is much like the SX coupling in that the disc packs are attached when the coupling is set up. In the close coupled units, the hubs are turned inward and are mounted within the spacer. Note that with the hubs inside the spacer, the maximum bore allowed within the hub will probably be decreased. The SXC couplings might be utilized with one particular or the two hubs turned outward to allow the coupling to accommodate various shaft separations.
Industrial SXCS and SXCST Sorts
The SXCS and SXCST Varieties have split spacers and also the disc packs could be serviced or eliminated without having moving the hubs within the shafts and without moving the equipment. The SXCS Variety has the bolts that connect the hubs on the split spacer installed from your ends of your couplings. The SXCST possess the bolts installed from inside the spacer pointing outward in the direction of the hubs.
