Shown are six 38RT/HLF flexible cou- pling assemblies as used on naval propulsion systems.

The 38RT couplings, which utilize elastomer cylinders pre-loaded in compression, have three dimensional lateral and torsional flexibility. They provide a high degree of noise atten- uation, there being no metal-to-metal contact.

The HLF multiple-lamination coupling components have high Lateral Flex- ibility and allow the ship propulsion systems to accommodate very high lateral (and associated) excursions.

The particular assemblies shown here have been qualified for acceler- ations in excess of 35.0 G.

THE LO-REZ 'SOFT MOUNT'

PACKAGE

For quiet, vibration-free operation and improved service life in pas- senger, commercial and naval ves- sels.

The configuration of the LO-REZ RT coupling provides many important characteristics such as two directional thrust and torque capability, shock absorption, excellent noise attenuation, high misalignment capability, etc.

The LO-REZ BR-T isolators have special thrust carrying devices which permit them to carry full thrust load without 'locking up' so that they are capable of providing effec- tive isolation of the engine-generated vibration over the entire speed range.

With the installation of the LO-REZ soft mount package there is no requirement for a thrust bearing in the low-speed shafting so that the full thrust is transmitted through the

RT coupling into the gearbox thrust bearing, and out to the gearbox/engine or raft brack- ets, to the LO-REZ isolators.

Your vibration-control products are the best on the market. I would not build another single-hulled passenger vessel without your Soft Mount System. LO-REZ has gained a lot of prominence. Frank Patti 0wner Patti Shipyardi |nc. 2. 'ISLAND QUEEN V'

Passengers are constantly remarking on the quiet and vibration-free performance. I will often take them down to the engine room and point to the LO-REZ Twin Isolation

These Torpedo and Ship-ranging vessels operate in an acoustically-sensitive area. The sophisticated LO-REZ systems make a significant contribution towards the quietness and smoothness, meeting various noise criteria neatly.

I found the LO-REZ system to more than meet my expectations, tit is) uncanny, like a sailboat or being towed. When standing on the bridge, I have to look at my instruments to see if the engines are running, so quiet and vibrationless is the machinery.
