Magnetic particle clutch is commonly known as the micro magnetic particle clutch, the use of DC24V DC voltage. It is a kind of automatic execution element, which is composed of the input shaft and the output shaft. The powder particles with high heat resistance and corrosion resistance, so it has good durability.
One, working principle:
In the space between the two axles is filled with granular powder. When the magnetic coil of conductive, can produce magnetic force and magnetic powder production hardening phenomenon, continuous sliding between the transmission torque, when the magnetic coil is not conductive, torque is not from the input shaft of the transmission output shaft.
Two, specifications:
International common standard torque has 1Nm, 2Nm, 5Nm, TJ-POC-C-0.5Nm, the unit can also use KG (note 1KG is about equal to 10Nm).
Characteristic:
Three, features:
Micro magnetic powder clutch has the advantages of easy control, continuous sliding, torque stability, quiet operation, good heat dissipation, long service life and so on. Natural cooling of micro magnetic powder clutch excitation current is small, but can output larger torque, which can be very convenient to form an automatic control system. In addition when the excitation current is changed, and the corresponding magnetic field strength along with synchronous response, and therefore have excellent response speed. When the exciting current is kept constant, the output torque can not be affected by transmission and follower between differential (slip speed), namely static moment and the difference of the torque. Therefore the natural cooling of the micro magnetic particle clutch can be very stable output constant torque. This feature if should be used for tension control, customers only need to adjust the size of the exciting current, is simple, effective and accurate to control roll feeding tension.
Micro magnetic powder clutch is widely used in electronic equipment, printers, printers, and other fields.
Four, installation method:
1, ready to bracket, the combination of the bracket, please put into the mounting plate and screw fixation;
2, into the force axis and output axis continuously, must the elastic coupling, and pay attention to the coupling and into the output shaft concentricity and angle;
3, install pulley gear or chain into equal to the output shaft, do not exceed the allowable range of Zhouduan load.
(1) the maximum speed is 1800r/min;
(2) in the course of operation, the surface temperature can not exceed 90.
Micro magnetic particle clutch and micro magnetic powder brake broader torque control the stability range of the sliding torque reaction fast in from the low current field until more than the rated current in a wide range, current and torque is is proportional to the, has good torque control characteristic. The design of the time to ensure that the inertia is very small, is an effective magnetic circuit design, so the separation of powder particles can be quickly, can give full play to the start stop at high frequency |
