Airflex® Expanding Type Clutches and Brakes Section C EATON Airflex® Clutches & Brakes 10M1297GP November 2012

Airflex® Expanding Features Section C E, EB, ER and VE elements utilize a rugged tire-like neoprene and cord tube that expands radially outward when pressurized. The expanding tube forces a friction surface against an inner cylindrical drum surface. The rate at which the tube is pressurized determines the rate at which element torque increases. Final tube pressure determines the element torque capacity. Design Features Force applied at maximum radius from axis Airflex expanding elements concentrate the frictional force on the inside drum diameter thereby achieving maximum torque. The torque lever...

Airflex® Expanding Features Section C Heat Dissipation Heat, generated at the inner drum surface, is quickly conducted to the drum's exposed outer surface area where it is dissipated by radiation and convection. This feature is ideal for slip clutch and tension brake applications where heat must be dissipated continuously. Drum design permits operation in any plane. A plate type unit operates best in a vertical plane. As friction surfaces wear, the tube expands further and compensates for the wear. Normal wear will not reduce torque capacity. • There are no close fitting sliding components which...

Airflex® E and VE Construction Section C E and VE Construction Type E and VE elements combine rugged design and rigid construction features which make them ideal for moderate to heavy duty clutch and brake service. They are suited for medium speed cyclic applications which are subject to large thermal loads. When used with an air agitating ventilated drum they provide excellent slip clutch and tension brake service. A neoprene rubber and cord tube is contained by two side housings. Friction shoes are held in position on the tube periphery by leaf springs which pass through the shoe back plates...
