Stainless Steel Coupling with Composite Spacer for Cooling Tower Applications

Radial spoke form membrane coupling with composite spacer element for long DBSE applications. Computer controlled, filament wound, matrix torque tube with stainless steel hubs, hardware and disc packs. Up to 80 percent lighter than comparable welded metal torque tubes and corrosion resistant for corrosive atmospheres. The unique spoke form membrane provides a good level of misalignment capacity, but in the rare event of membrane failure, the drive is disconnected, permitting the driven half to safely come to rest, without further damage to the machine.

• Computer controlled, filament wound, matrix torque tube with stainless steel hubs, hardware and disc packs.

• Suitable for vertical line shafts without excessive loads on the membranes.

• Inherent balance to AGMA Class 9.

• Eliminates intermediate bearings for shaft separation (DBSE) to over 19ft/6m.

• Ease of installation - no crane required.

• Minimum downtime, optimum reliability.

• Stainless steel construction of all components, other than the spacer.

• Tube design virtually eliminates thermal expansion and sag.

• Corrosion resistant to cooling tower environment and temperatures up to 300°F/150°C.

• Piloted fit of hub to disc pack to torque tube assures dynamic balance retention.

• Unique disc pack spokes are designed to shear if torque overload or excessive misalignment conditions occur, protecting expensive motor and gear.

• Increases machinery life.

• Minimizes weight of drive shafting up to 80% lighter than equivalent steel torque tubes.
