German Eriem brake Eriem model Eriem price

Eriem brakes, also known as disc brakes, pneumatic brakes, air-operated disc brakes, and air-hydraulic pneumatic brakes, are a type of industrial transmission brake. They are actuators that use air pressure to stop or decelerate moving parts in machinery. The structure is simple, installation is convenient, and they are durable, resistant to pressure, drops, and impacts, with a long service life. Generally, only the brake pads need to be replaced, which is easy and convenient. They utilize magnetic effects.

Eriem Brake Introduction

Pneumatic brakes control the friction between the brake disc and friction plates based on air pressure to adjust the braking torque on the paper roll. The installation, structure, and tension control principle of the pneumatic brake are shown in the figure. The installation position of the pneumatic brake and the paper roll mandrel is shown in (a) of the figure. The structure of the pneumatic brake is shown in (b) of the figure. The brake disc 5 is connected to the paper roll shaft. Fixed friction plates 8 and movable friction plates 7 are installed on both sides of the brake disc 5. Under normal conditions, there is a gap of 1 to 2mm between the fixed friction plates 8 and the brake disc 5 (the gap is adjustable). The movable friction plates 7 are mounted on the piston rod 4 of the cylinder. The compressed air port 2 on the left side of the piston is connected to the air compressor, and the right side of the piston is connected to the atmosphere through an air hole 1. The friction between the movable friction plates 7 and the brake disc 5 is controlled by the air pressure on the left side of the piston, thereby controlling the braking torque on the paper roll. The initial air pressure for the movable friction plates 7 is set according to the paper and printing tension requirements. As the tension changes during paper roll unwinding, the position of the floating roller (see (c) in the figure) changes, causing the sensor 9 to rotate by an angle and send a feedback signal. This adjusts the air pressure on the movable friction plates 7, changing the friction between the movable friction plates 7 and the brake disc 5, thereby altering the web tension to ensure stability. If greater braking torque is required, the fixed friction plates 8 can be adjusted to contact the brake disc 5. In the event of a paper break or emergency stop, the air pressure is rapidly increased, causing the friction plates to lock the brake disc 5, preventing the paper roll from bunching due to inertia.

Eriem Brake Features and Applications

Due to their simple structure, stable operation, easy installation, noiseless operation, good linearity, no no-load torque, fast heat dissipation, light weight, easy adjustment, and high temperature resistance under high load, pneumatic brakes are widely used in various industrial mechanical transmission systems, including wire and cable equipment, packaging machinery, printing machinery, textile machinery, wire and cable machinery, winding machines, and machine tool equipment. Pneumatic brakes can perform functions such as disengagement, engagement, inching, reversing, and speed changing. They operate at DC24V voltage, and the voltage fluctuation must not exceed ±5% of the rated voltage. The friction surfaces must not be contaminated with oil or any debris that could affect the normal operation of the disc brake. When installing the air-operated disc brake, axial positioning is required. The air gap should be adjusted to the specified value, and for split-shaft installations, the coaxiality should be maintained within 0.1mm to ensure normal operation and performance of the pneumatic brake. Compared to drum brakes, disc brakes have flat working surfaces with heat dissipation from both sides. The disc rotates and cools easily, is less prone to significant deformation, and provides stable braking performance. Prolonged use causes the brake disc to expand due to high temperatures, enhancing the braking effect. In contrast, drum brakes dissipate heat from a single surface, resulting in a large temperature difference between the inner and outer surfaces, which makes the brake drum prone to deformation. Additionally, prolonged braking causes the brake drum to expand due to heat, reducing braking efficiency. Furthermore, disc brakes have a simple structure, are easy to maintain, and facilitate automatic adjustment of the brake gap. Pneumatic brakes are widely used as actuators in mechanical transmission systems for machine tools, motors, packaging machinery, printing machinery, paper machinery, textile machinery, office equipment, metallurgical machinery, tobacco machinery, automated production equipment, and woodworking machinery, performing functions such as clutching, reversing, speed changing, braking, and positioning.

Eriem Brake Maintenance Methods

To ensure uninterrupted operation of the electromagnetic brake, regular maintenance and care are essential: 1) Regularly add lubricant to the moving parts of the electromagnetic brake. 2) Regularly check the length of the armature stroke. During operation, wear on the braking surface increases the armature stroke length. If the armature stroke length falls below the normal value, it must be adjusted to restore the minimum gap between the braking surface and the rotor. If the armature stroke length exceeds the normal value, the suction force may be significantly reduced. 3) If worn braking surfaces are replaced, the minimum gap between the braking surface and the rotor must be readjusted appropriately. 4) Regularly check the tightness of bolts, especially tightening the bolts for the electromagnet, the electromagnet-to-housing bolts, the yoke bolts, the electromagnet coil bolts, and the terminal bolts. 5) Regularly inspect the mechanical wear of moving parts and remove dust, lint, and dirt from the surface of the electromagnet components.
