Disc Coupling Overview

Industrial SU Sort
The SU Style coupling has a single flex plane with two hubs along with a single disc pack. It is suitable for angular and axial misalignment only. Two SU couplings are frequently mixed which has a shaft
to produce a floating shaft coupling. The shaft is often hollow for prolonged light weight floating shaft couplings.
Industrial SX Type
This really is the standard coupling variety that incorporates two hubs, a stock length spacer intended to meet market standard lengths, and two unitized disc packs. The coupling has two flex planes, one at each and every disc pack, allowing this coupling to accommodate parallel, angular, and axial misalignment with specified limits. The coupling is available in 6 and 8 bolt models and bore sizes up to 13 inches (330mm) to the greatest size. Custom spacer lengths might be manufactured to meet specific shaft separations needed for distinct applications. The SX coupling is usually fitted with overload bushings to guard the disc packs in in excess of torque circumstances and can act as an anti-flail device. SX couplings are assembled at the time of set up around the gear in which the coupling will likely be in support.
Industrial DI Type
The DI Kind coupling features a “Drop-In” spacer assembly which is assembled on 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 on the spacer and guard rings in the factory making use of the torque values encouraged by Lovejoy for that disc pack bolts. With all the hubs mounted around the shafts, the entire disc pack assembly may be “Dropped In” place in between the two hubs. The hubs are piloted to ensure correct centering on the spacer assembly. This piloting serves as an anti-flail feature and aids in the coupling’s capacity to meet the balance standards mandated by API. This style coupling is made to meet the balance and anti-flail necessities specified in API-610.
Oversized, or Jumbo, hubs can be found for use using the DI Type coupling to permit for bigger bore sizes on most DI coupling sizes. This allows for your utilization of smaller DI couplings in applications exactly where a smaller size coupling can nevertheless accommodate the application torque.
Industrial SXC Form
The SXC Style would be the shut coupled variation in the SX Style coupling. The SXC is similar to the SX coupling in the disc packs are attached when the coupling is installed. Inside the near coupled units, the hubs are turned inward and therefore are mounted within the spacer. Note that together with the hubs within the spacer, the utmost bore allowed inside the hub will likely be decreased. The SXC couplings is often applied with one particular or each hubs turned outward to allow the coupling to accommodate diverse shaft separations.
Industrial SXCS and SXCST Styles
The SXCS and SXCST Sorts have split spacers plus the disc packs can be serviced or removed without moving the hubs about the shafts and with no moving the tools. The SXCS Variety has the bolts that connect the hubs on the split spacer installed from the ends from the couplings. The SXCST possess the bolts set up from inside the spacer pointing outward in the direction of the hubs.
