The Work form of industrial Drum brake
Dec 09, 2017

The industrial Drum brake is often used in mechanical operation parts, which is an indispensable part of mechanical equipment operation.

industrial Drum brake is a kind of brake. How does it brake in the process of work? Let's take a look at it.

The industrial Drum brake is on the surface of two arc-shaped brake shoes to hold the brake friction pieces, and the brake shoe is supported at one end, and the power is applied from the other end to make the brake shoe press the inside of the brake drum and brake.

In the hydraulic braking system, the piston of the brake cylinder pushes the brake shoe directly.

In a pneumatic braking system, the compressed air pushes a CAM to rotate to make the brake shoe outwards.

When the brake pressure disappears, the brake shoe is pulled out of the brake drum by the return spring to lift the brake.

Under the condition of certain hoofs and drum position, the industrial Drum brake can produce automatic increasing force.

Is based on the direction to the rotation of the brake drum, if the wire end of the brake shoe at first, supporting the last, the rotation of the rotation direction of the brake shoe and brake drum in the same direction, then, under the action of friction, the brake shoe will automatically with more pressure to the brake drum, powerful brake can be obtained.

Such a brake shoe is called a helping hoof.

Of course, because the car can move forward, also can retreat, when the rotation direction of the brake shoe and brake drum rotating in opposite directions, hoof, friction between the drum and decreased, the pressure of the brake shoe also decreases, and the brake shoe is called because stumbles.
