Commonality Of Magnetic Powder Brake And Magnetic Powder Clutch

The magnetic powder brake has no sound, and the slip phenomenon of the action surface occurs in the friction mode, but it does not appear here. It is easy to carry out a wide range of control, and it does not emit a connection sound, so the operation is quite safe and can achieve continuous sliding. In operation, stable torque can be obtained, buffer start and stop, and the start and stop of the buffer can be achieved by the smoothing characteristics and the constant torque characteristics at the time of connection.
When the magnetic powder clutch input shaft and the output shaft are installed in reverse, the machine will idle for a long time, the magnetic powder is stirred, and the magnetic powder clutch will greatly shorten the service life of the magnetic powder clutch. When the heat dissipation condition is constant, the slip power is a certain value, so the actual The working torque and the speed can be compensated for each other. When the slip speed is increased, the allowable torque will decrease accordingly, but the maximum speed must not be higher than the permitted speed.

Since the magnetic powder brake uses a magnetic powder with excellent heat resistance and an ideal cooling method, it must be kept within the allowable sliding operation rate. Even if it is too harsh continuous sliding operation, it can be used with peace of mind, due to the static friction coefficient. It has almost the same coefficient of friction as the dynamic friction coefficient. Therefore, it does not oscillate when it is completely connected. It can be accelerated or decelerated according to the load. When it is installed in the gearbox, the oil will penetrate into the inside through the shaft. Therefore, the film should be completely sealed.

Magnetic powder brake, magnetic powder clutch

The magnetic powder brake and the magnetic powder clutch are magnetic powder as the working medium, and the excitation current is used as the control means to achieve the purpose of controlling the braking torque or transmitting the torque. The output torque has a good linear relationship with the excitation current, and has nothing to do with the speed or slip, and has the advantages of fast response speed and simple structure.

Used for torque speed power test system. Magnetic powder brake, magnetic powder clutch and torque speed sensor, torque speed power measuring instrument, can form a complete set of torque speed power test system, widely used in power machinery, transmission machinery input, output torque, speed, power, efficiency Dynamic and static detection.

The magnetic powder clutch is also used for buffer starting, overload protection, speed regulation and the like.

The magnetic powder brake is based on the electromagnetic principle and uses magnetic powder to transmit torque. It has the characteristics that the excitation current and the transmission torque are basically linear. It can transmit a certain torque regardless of the slip, and has the advantages of fast response, simple structure, no pollution, no noise, no impact vibration and energy saving.

Magnetic powder brakes are also often used for dynamometer loading and braking of transmission machinery. Magnetic powder brakes and magnetic powder clutches are often paired.

If the magnetic powder gets wet, the performance will become unstable, so be careful not to let oil or moisture invade the inside.

Magnetic powder brake, magnetic powder clutch, automatic tension control instrument and tension detecting sensor can form an automatic closed-loop tension control system, which is widely used in printing, packaging, paper and paper processing, textile, fiberglass, wire and cable rubber leather, metal foil tape. Processing and other equipment.
