German Ringspann brakes, Ringspann models, Ringspann prices

Ringspann brakes are the actuating components in the entire braking system. The electromagnetic brake is installed on the trailer wheels. Its structure is shown in Figure 1. The entire brake mainly consists of components such as the electromagnet, lever drive mechanism, front and rear brake shoes, base plate, and friction ring. It is a mechanical part that stops or decelerates moving parts in machinery. Commonly known as brakes. Brakes mainly consist of a brake frame, braking elements, and operating devices. Some brakes are also equipped with automatic adjustment devices for braking element clearance. To reduce braking torque and structural dimensions, brakes are usually installed on the high-speed shaft of the equipment, but for large equipment with high safety requirements (such as mine hoists, elevators, etc.), they should be installed on the low-speed shaft near the working part of the equipment.

Ringspann Brake Introduction

Pneumatic brakes control the friction between the brake disc and friction plates by adjusting air pressure, thereby achieving the purpose of adjusting the 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. Under normal circumstances, there is a gap of 1 to 2mm between the fixed friction plate 8 and the brake disc 5 (the gap is adjustable). The movable friction plate 7 is installed on the piston shaft 4 of the cylinder. The compressed air interface 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 between the movable friction plate 7 and the brake disc 5 is controlled by the air pressure on the left side of the piston, thereby controlling the braking force of the paper roll. The initial air pressure of the movable friction plate 7 is set according to the paper and printing tension requirements. During the unwinding of the paper roll, if the tension changes, the position of the floating roller (see (c) in the figure) changes, driving the sensor 9 to rotate by an angle and send a feedback signal. This adjusts the air pressure of the movable friction plate 7, changing the friction between the movable friction plate 7 and the brake disc 5, thereby changing the web tension to ensure stable tension. If greater braking force is required, the fixed friction plate 8 can be adjusted to contact the brake disc 5. In the event of paper breakage or emergency stop, the air pressure is urgently increased, causing the friction plates to lock the brake disc 5, preventing the paper roll from bunching due to inertia.

Ringspann Brake Characteristics and Applications

Due to characteristics such as simple structure, stable operation, easy installation, noiselessness, 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 adopt a voltage of DC24V, and the voltage fluctuation must not exceed plus or minus 5% of the rated voltage. The friction surfaces must not be contaminated with any oil stains or other debris that may affect the normal operation of the disc brake. When installing the pneumatic disc brake, axial positioning should be performed, the air gap should be adjusted to the specified value, and for split shaft installation, the coaxiality should be maintained within a range not greater than 0.1mm to ensure normal operation and characteristics of the pneumatic brake. Compared with drum brakes, disc brakes have flat working surfaces and heat transfer on both sides. The rotating disc is easy to cool, less prone to significant deformation, and provides stable braking performance. After long-term use, the braking effect is enhanced due to the thermal expansion of the brake disc at high temperatures. In contrast, drum brakes have single-sided heat transfer, resulting in a large temperature difference between the inner and outer surfaces, which makes the brake drum prone to deformation. Meanwhile, after prolonged braking, the brake drum expands due to high temperature, weakening the braking efficiency. Additionally, disc brakes have a simple structure, are easy to maintain, and facilitate automatic adjustment of braking clearance. Pneumatic brakes are widely used as actuating elements in mechanical transmission systems of machine tools, motors, packaging machinery, printing machinery, paper machinery, textile machinery, office equipment, metallurgical machinery, tobacco machinery, automated production equipment, and woodworking machinery, thereby performing functions such as clutching, reversing, speed changing, braking, and positioning.

Ringspann Brake Maintenance Methods

To ensure uninterrupted operation of the electromagnetic brake, regular maintenance and care are required: 1) Frequently add lubricant to the moving parts of the electromagnetic brake. 2) Regularly check the length of the armature stroke. Because during the operation of the brake, the armature stroke length will increase due to wear on the braking surface. When the armature stroke length does not reach the normal value, it must be adjusted to restore the minimum gap between the braking surface and the rotor. If the armature stroke length increases beyond 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 should be readjusted appropriately. 4) Frequently check the tightness of bolts, especially tightening the bolts of the electromagnet, the bolts between the electromagnet and the housing, the bolts of the yoke, the bolts of the electromagnet coil, and the wiring bolts. 5) Regularly check the mechanical wear of moving parts and remove dust, lint, and dirt from the surface of the electromagnet parts.
