DFB, QFB (HC series) Spring Brake

1. Brake with aid of spring.
2. Automatic braking happens when power is cut off and in case of low air pressure.
3. The brake is disc-structured and will therefore not be affected by centrifugal force during high-speed rotation; its torque is quite stable.
4. The brake is attached with heat releasing plate and is thus characterized by its superior performance of heat dissipation.
5. Sliding part is spline structured. The brake works smoothly and reacts well.
6. The friction plate is unit structured. Air flow is guaranteed, cooling and heat dissipation is hence effective.
7. Low inertia allows the brake stopping well at high speed.
8. Applicable to conveying machine, lumber making machine, can making machinery, iron making machinery and general industrial machinery.
9. Installation instruction: refer to the manual for Air Clutch & Brake.

Structure:

DFB and QFB brakes work with aid of spring and release by feeding air inside.

When air is discharged, air chamber, pressure plate and friction plate move due to pressing force of spring; disc then contacts the friction plates on both sides.

Friction plate, disc, housing body and hub slide smoothly with aid of splines.

When air is fed to the air chamber, the brake spring is pressed; friction plate then act in a special condition and brake releases.
