Airflex CB element assemblies are used as both clutches and brakes in general power transmission service. The primary feature of the CB design and construction is the Airflex torsional resilient principle made possible by the transmission of power through the side walls of the flexible neoprene and cord actuating tube. This flexibility also permits minor shaft misalignment.

The hydraulic shoe brakes are spring released and hydraulically set for controlled stopping. Applications such as indoor and outdoor bridge cranes are just some of the examples. These proven high performance brake systems are tough, reliable and provide trouble free service. Brake wheel sizes ranging from 6 inches to 18 inches are available. Brakes are available either with standard hydraulic setting, setting with parking feature or with air powered hydraulic operation. The powered systems may be direct or remote controlled. Air remote control, hydraulic remote control, and electric remote control allow the customer the flexibility to satisfy most requirements.

Electro-Hydraulic Drum Brakes
Electro-hydraulic drum brakes can be extensively used for various mechanisms deceleration and stop/braking of various lift, belt transport, port handling, metallurgical and building machinery.

The magnetic DC shoe brakes are spring set and electrically released. The brake is set when 230 VDC power is removed from the brakes coil(s). The type TM brakes electrical mechanism consists of one or two DC magnets. As power is introduced to the coils it creates an electro-magnetic field that brings the coils together to release the brake. Cutting power to the coils allows the spring to extend back to its normal state and sets the brake. Shunt or series coils are available and rated for continuous or intermittent duty ratings. We also offer single point adjustment on brakes 8 inches in wheel diameter or larger. This speeds up the brake installation and shoe lining wear adjustment by a single point adjusting feature. Brake wheel diameters of 41/2" to 30" are available, and are AISE rated. Rectifiers are available for AC operation.

Airflex E elements are primarily used as slip clutches or tension brakes; however, they can also be used for general power transmission service. Torque is transmitted from the friction shoes to the element housing through torque bars. Engagement occurs when air expands the actuating tube forcing the friction shoes against the inside diameter of the drum. Release springs assist shoe disengagement and counteracts centrifugal force.

Simple to be intalled and compact; the Airing radial units are engaged by an air tube and can be used as drum brakes (in stopping and holding applications) or clutches (to connect two shafts directly or through a pulley).
Maximum torque from 40 to 4 000 Nm.
The high thickness friction pad and the reliable air tube ensure high performances and low maintenance cost.

The DC and DCV constricting drum clutches and brakes are found all throughout industry in general power transmission duties.
Constructed using an integral rim and tube actuator, the DC has low inertia and high misalignment capacity, offering a simple solution to less arduous clutch and brake requirements.
A full range of options is available: Dual flanges for back to back mounting giving double torque capacity. Multiple air inlets for increased response speed. Split construction to avoid removal of the shafts on in-line drives. And wether you require just the friction shoe or mounting pins, or a complete actuator and rim assembly, all are backed by the Wichita name for service and reliability

Airflex VE elements were specially designed for greater heat dissipation capacity in an expanding type element. Available in a limited number of sizes, they offer all of the type E features.
|
|
|
Airflex EB element assemblies are used in both clutch and brake service with light starting loads. The EB is similar in design to the CB except that it is an expanding type unit.
|
|
|
Airflex ER couplings are expanding units with neoprene facing. As such, they combine the advantages of a flexible and disconnect coupling. Engagement of the element should occur when there is no speed differential between driving and driven shaft.
