Application:
Printing machinery, paper industry machinery, bag-making machinery,
paper-making machinery , wire and cable machinery,coil
machinery,wire machinery,strapping bag machinery, textile
machinery, weaving-dimensional machinery, woodworking machinery,
test equipment, analog load use, the kinds of mechanical precision
tension controlling,general industrial equipment, other general
industrial machinery.
Attention for using magnetic powder brake:
1 Install it with correct mounting method (make high-speed rotation
side as the input side) to use the magnetic powder clutch. If the
mechanical structure of output and input shafts have to be
installation reversely, make sure to use the under 1000R/MIN. If
the output shaft and input shaft be installed reversely, which will
make the machine idle for a long time, the magnetic powder clutch
will greatly shorten the life by mixing magnetic powder.
2 Note the moisture. If the magnetic is damp, then performance will
become unstable, so be careful do not to let the oil or water get
into the housing. Especially when installed in the gear box, oil
penetrated the internal branch of the housing through the shaft, so
please seal it with film completely.
3 Note the surface temperature. Caused by continuous operation, the
maximum temperature of the surface is below 90 degree when running
more, than the value and durability will be greatly reduced. Make
sure to limit the temperature will not above90 degree, make sure to
keep the use of sliding within allowed work range.
General introduction:
The magnetic powder clutch is composed of active rotor (input
shaft),driven rotor(output shaft) and yoke with excitation coil.
The three parts are assembled relative concentric and form a system
which can rotate relatively. The annular gap between active rotor
and driven rotor is full of magnetic alloy powder which has high
magnetic conductivity.
The magnetic powder will be in the state of loose situation when
the current do not pass the excitation coil, the magnetic powder
will be thrown on the inner wall of active rotor, in this case,
there will not exist the interaction force between the active and
driven rotor. So the magnetic powder clutch is in the state of
separation, no torque transmission exits.
The magnetic powder in the working chamber will link in a link
state under the action of the magnetic flux generated from the yoke
when the current pass the excitation coil. The magnetic powder
clutch can transfer torque relying on the shear force generated
from magnetic chain and the friction generated from the magnetic
powder and working face. In this situation, the magnetic powder
clutch is in the combination state.
When the current is cut off, the magnetic flux will disappear along
with the disappearance of the magnetizing current, the magnetic
powder will be in the state of loose under the action of gravity
again, and will be thrown on the inner wall of active rotor under
the action of the centrifugal force.
In this case, the magnetic powder clutch will be in the state of
separation again.
The magnetic powder clutch and brake have the same principle, the
magnetic powder brake will form as long as driven rotor of the
magnetic powder clutch is fixed.
