Eaton Airflex

CB Clutches and Brakes

Available from Clutch Engineering, the Eaton Airflex CB element assembly is useful for integrating with metal forming equipment, printing systems, oil and gas equipment, and rubber processing plants. The product is air-actuated, with an integrated neoprene rubber air tube that provides the necessary clamping force. The torque lever arm is the drum radius, not a reduced radius as occurs in plate clutches. There are friction shoes mounted on the tube’s inside diameter, and they engage around a cylindrical drum when in operation. In this design, the neoprene rubber air tube is bonded to the outer steel rim. Airflex constricting elements concentrate the frictional force on the outside drum diameter, which functions to achieve maximum torque. Not only is the force generated at the optimum radius, it is also applied uniformly around the drum circumference.

Torque range: 360 to 260,000 lb-in (41 to 29,400 Nm)
Typical applications: Metal forming, printing, oil and gas, rubber processing

VC Clutches and Brakes

Available form Clutch Engineering, the Eaton Airflex VC element assembly is often used for grinding mills, marine propulsion systems, and metal forming machinery. This high-quality clutch and brake product is an air-actuated constricting drum unit. The VC’s ventilated design and construction allows for the rapid dissipation of heat that can be generated during operation. The torque that the unit experiences is carried by torque bars, and leaf springs function to retract the friction shoes when air pressure is released. Due to this construction, all components are conveniently available as replacement parts when refurbishing the unit. The type VC element assembly is specifically constructed for severe clutch or brake applications. These include applications in which large inertia loads and sustained slippage would otherwise result in a loss of torque and a reduced operating life.

Torque range: 27,000 to 3,660,000 lb-in (3,050 to 413,057 Nm)
Typical applications: Grinding mills, marine propulsion, metal forming machinery

The brake’s large friction area allows it to absorb and dissipate high energy loads. Lining wear adjustments aren’t required for single disc units, and dual disc units require only one wear adjustment over the entire life of the friction material. These disc style brakes develop equal torque in either direction of rotation. Torque and thermal capacities allow them to be used in many of the most demanding applications.

Torque range: 176,700 to 339,000 lb-in (20,000 to 38,400 Nm)
Typical applications: Can-making machines, draglines, power shovels, conveyors, power presses

The low inertia of relevant rotating components makes the DBB ideal for cyclic applications. These spring-applied, pressure released, disc style brakes develop equal torque in either direction of rotation. Built-in torque and thermal capacities allow them to be used in many demanding applications.

Torque range: 7,500 to 1,470,000 lb-in (847 to 166,101 Nm)
Typical applications: Bottling equipment, conveyors, shears

Rotorseals

Clutch Engineering offers rotorseals from Eaton Airflex. These advanced rotorseals allow air or hydrolic fluids to be transferred from a stationary supply to a rotating shaft. The compatible air or fluids can be used to control clutches and brakes, lubrication, or cooling oil. For these products, the rotating seal is created and maintained by a non-metallic sealing ring, positioned tightly against the rotorseal shaft by a light spring force. The sealing ring is designed so that media pressure acts on both of its ends to minimize the force on the sealing surface. Rotorseals are available with single, dual, and triple passages to suit your specific mechanical needs.

Quick Release Valves

Clutch Engineering offers Eaton Airflex quick release valves (QRV) as a high-quality valve solution for many use cases. These products are three-way valves that are designed to allow for a faster exhaust of air out of your brake or clutch. This increase in the speed of air flow can enable faster cyclic rates and reduce any overlap between clutches and brakes. Optional muffler attachments are also available, for effectively reducing the exhaust noise of a system. Four basic valve sizes are available for these quick release valves. These are identified by the American National Pipe Thread on the cylinder port: 3/8″, 1/2″, 3/4″ and 1″ NPT. Models are also available with inlet ports that are compatible with pipe or tubing connections.

FHB Brakes

Clutch Engineering offers Eaton Airflex’s FHB brakes for applications such as dragline hoist systems, drag, and swing applications, as well as other use cases. These high-quality products use a patented floating housing design instead of a typical floating rotor design. These brakes are particularly well suited for heavy-duty industrial applications like those found in surface mining and oilfield machinery. FHB brakes are air-cooled disc brakes that are spring applied and pressure released. Benefits include the ability to quickly change the friction pads reduces down time on dragline from 3 hours to 1 hour and a reduced maintenance cost with elimination of spline tooth or gear wear.

Torque range: 288,000 to 432,900 lb-in (32,540 to 48,918 Nm)
