German Deutsche van brake Deutsche van model Deutsche van price

Deutsche van brake is a connector that transmits torque from the driving side to the driven side. It can be freely engaged, disengaged, or braked as required. It features a 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, mainly serving to transmit power and control motion in mechanical transmission systems.

Introduction to Deutsche van brake

Pneumatic brakes rely on air pressure to control the friction between the brake disc and friction plates, thereby 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 conditions, there is a gap of 1～2mm between the fixed friction plate 8 and the brake disc 5 (the gap is adjustable). The movable friction plate 7 is 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 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 on the paper roll. The initial air pressure for the movable friction plate 7 is set according to paper and printing tension requirements. During paper unwinding, changes in tension cause the position of the floating roller (see (c) in the figure) to change, rotating the sensor 9 by an angle and sending a feedback signal. This adjusts the air pressure on the movable friction plate 7, changing the friction between the movable friction plate 7 and the brake disc 5, thereby altering the web tension to ensure stability. 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 rapidly increased to lock the brake disc 5 with the friction plates, preventing paper piling due to inertia.

Working principle of Deutsche van brake

The working principle of a pneumatic brake involves inputting pressurized gas into the air bag of the pneumatic brake, pushing the piston to perform linear motion, thereby pressing the brake friction blocks against the brake wheel to generate friction and achieve braking. Pneumatic brakes engage via air pressure and release via return springs. The disc slides along the shaft direction due to air pressure, contacting the friction plate. Components such as the disc and friction plate are assembled onto the hub to form an integrated structure. Friction plates can be disassembled by unscrewing the adjustment nut, making replacement simple. Pneumatic brakes are installed on the shaft using a tapered bushing with a wedge, allowing friction plates to be replaced while keeping the mechanical equipment intact. Heat generated by friction is dissipated by cooling fins installed on the disc with the hub. The friction plates are split with double cuts; they can be replaced by removing the countersunk screws through the holes in the disc with the hub using a screwdriver. Pneumatic brakes offer good heat dissipation and are widely used in packaging machinery, wire and cable equipment, thin paper, and corrugated paper industries. Pneumatic brakes are also known as air brakes, meaning an air bag applies pressure via ventilation to close the jaws tightly for braking. This type is widely used in industry. Pneumatic brakes are further divided into normally closed and normally open types. A normally closed brake has its jaws open when not working; applying air pressure engages the brake, creating the braking effect.

Application notes for Deutsche van brake

Used in metallurgy, construction, chemical, food, machine tools, stage, elevator, ship, packaging, and other machinery, as well as for braking during power outages (safety). Brakes that utilize electromagnetic effects for braking include electromagnetic powder brakes, electromagnetic eddy current brakes, and electromagnetic friction brakes. 1) Electromagnetic powder brake: When the excitation coil is energized, a magnetic field is formed. Magnetic powder is magnetized under the influence of the magnetic field, forming magnetic powder chains that aggregate between the stationary magnetic conductor and the rotor. Braking is achieved through the bonding force and friction of the magnetic powder. When the excitation current disappears, the magnetic powder returns to a free, loose state, and the braking action is released. This type of brake is small in size, light in weight, and has low excitation power. The braking torque is independent of the rotational speed of the rotating parts, but the magnetic powder can cause component wear. It facilitates automatic control and is suitable for drive systems of various machines. 2) Electromagnetic eddy current brake: When the excitation coil is energized, a magnetic field is formed. The armature on the brake shaft rotates, cutting magnetic flux lines to generate eddy currents. The interaction between the eddy currents in the armature and the magnetic field creates braking torque. Electromagnetic eddy current brakes are robust, durable, easy to maintain, and have a wide speed regulation range; however, efficiency is low at low speeds and temperature rise is high, so heat dissipation measures must be taken. This type of brake is commonly used in machinery with vertical loads. 3) Electromagnetic friction brake: When the excitation coil is energized, a magnetic field is generated, attracting the armature through the yoke. The armature achieves shaft braking via the connection flange. Further subdivisions include electromagnetic dry single-disc brakes, dry multi-disc brakes, and wet multi-disc brakes. Braking methods can also be classified as power-on braking and power-off braking.
