German kendrion binder brakes, kendrion binder models, kendrion binder prices

kendrion binder brakes are connectors that transmit torque from the driving side to the driven side. They can be freely engaged, disengaged, or braked as required, offering advantages such as compact structure, simple operation, sensitive response, long service life, reliable use, and ease of remote control. Electromagnetic brakes are ideal automation actuators in modern industry, primarily serving to transmit power and control motion in mechanical transmission systems.

Introduction to kendrion binder brakes

Pneumatic brakes control the friction between the brake disc and friction plates by adjusting air pressure, thereby achieving the desired braking force on the paper roll. The installation, structure, and tension control principle of the pneumatic brake are shown in the figure. The installation positions of the pneumatic brake and the paper roll mandrel are 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. Generally, 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 the air hole 1. The friction force 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 force on the paper roll. The initial air pressure for the movable friction plates 7 is set according to the paper and printing tension requirements. During paper unwinding, if the tension changes, 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 force between the movable friction plates 7 and the brake disc 5, thereby altering the web tension to ensure stability. If greater braking force is required, the fixed friction plates 8 can be adjusted to contact the brake disc 5. In the event of paper breakage or emergency stop, the air pressure is rapidly increased to lock the brake disc 5 with the friction plates, preventing the paper roll from bunching due to inertia.

kendrion binder brake characteristics 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 wire and cable equipment, packaging machinery, printing machinery, textile machinery, wire and cable machinery, winding machines, machine tool equipment, and various industrial mechanical transmission systems. 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 pneumatic disc brake, axial positioning is required. The air gap should be adjusted to the specified value, and for split shaft installation, the coaxiality should be maintained within 0.1mm to ensure normal operation and performance of the pneumatic brake. Compared with drum brakes, disc brakes have flat working surfaces with heat transfer on both sides. The disc rotates and cools easily, is less prone to significant deformation, and provides stable braking performance. After prolonged use, thermal expansion of the brake disc enhances braking action. In contrast, drum brakes transfer heat from only one side, resulting in a large temperature difference between the inner and outer surfaces, which makes the brake drum prone to deformation. Additionally, after prolonged braking, thermal expansion of the brake drum reduces 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, papermaking 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.

kendrion binder brake maintenance methods

To ensure uninterrupted operation of electromagnetic brakes, 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 brake operation, the armature stroke length increases due to wear on the braking surface. When the armature stroke length deviates from 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 of the electromagnet, the bolts between the electromagnet and the housing, the yoke bolts, the electromagnet coil bolts, and the wiring bolts. 5) Regularly inspect the mechanical wear of moving parts and remove dust, lint, and dirt from the surface of the electromagnet components.
