Flexible Rotary Shaft Flexible Drive Shaft Flexible Cable

【 Product Description 】

The flexible shafts permit greater design freedom because they eliminate the complex coordination of multiple components. System designers can incorporate flexible shafts at any project-development stage and install the shafts in minutes without special tools or skills. A flexible shaft can run almost indefinitely in a straight configuration.

【 Applications 】

• Flexible rotary shafts transfer power from thrust-reverser actuation systems on jet engines.

• On commuter aircraft, typically 100 seats and smaller, ball-screw linear actuators control the leading (slat) and trailing (flap)      edges of the wings. Long flexible shafts that extend out from the fuselage drive these actuators. To increase fuel efficiency on long-range aircraft, variable-area fan nozzles are driven by flexible shafts to increase or reduce the engine exhaust area.

• In medical applications, orthopedic bone drills often operate in hard to reach locations. Flexible-shaft drill-bit assemblies let surgeons access these spots, saving time and permitting smaller incisions. Likewise, flexible shafts are useful in endoscopic instruments and surgical staplers.

• Cars and trucks rely on flexible shafts in power-seat tracks, power windows, foot-pedal adjusters, and sunroofs.

【 Design Guidelines 】

Regardless of the application, the most important variables to consider when choosing or designing a flexible shaft are the torque, directional operation, minimum bend radius, deflection, and speed. In some applications it is useful to additionally determine the point of helix and axial stretch. Keep in mind for any application the operating environment could change the type of material chosen as well as other design elements.
