PNEUMATIC CLUTCH BRAKE VC TYPE

Pneuflex PAC (VC) products are designed and built for severe clutching and braking applications on heavy duty equipment. When compared with conventional clutches they offer:

· Ventilated construction for rapid heat dissipation

· High starting loads

· Sustained slippage

· Improved efficiency

· Extended operating life

· Smaller diameters with lower velocity

Â

Pneuflex PAC / VC the torque is transmitted by torque bars rather than the sidewalls of the actuating tube. The loose actuating tube is contained within a housing formed by a rim and two side plates, and is replaceable. The torque bars, which are held in position by the side plates, pass through cavities in the backing plates of the friction shoes. Pressurizing the actuating tube forces the friction shoes to engage around a cylindrical drum. Leaf springs in the torque bar cavities of the backing plates retract the friction shoes when the actuating tube pressure is released. pacity is dependent upon the applied pressure and rotating speed. Catalogue ratings are given at 75 psi (5.2 bar) and zero rpm. Maximum recommended pressure is 125 psi (8.6 bar).

FEATURES:

· The Type PAC / VC is specifically designed and built for severe clutch or brake applications in which large inertia loads and sustained slippage would normally result in loss of torque and reduced operating life.

· Typical Applications: Grinding mills, marine propulsion, metalforming machinery, oil & gas machinery
