In
general, the structure of the spindle can be divided into six parts,
which are the main shaft, the spindle bearing, the spindle unit housing,
the motor without the shell, the module for the drive and the cooling
device, etc. Of the rotor assembly method is pressed and the rotor and the spindle is connected into a unified whole. The
spindle of the spindle is assembled by a front bearing and a rear
bearing, and the stator of the motor is mounted in the housing of the
spindle, but it is necessary to use a cooling jacket to secure the
stator first. And
the change in spindle speed is determined by its drive module. If the
temperature inside the spindle is too high, the cooling device inside
the spindle will limit its temperature to protect the spindle from
damage. The
motor of the spindle is a direct device in its spindle device, and when
the motor spindle is operating, the motor operates at a very fast
speed, so that a lot of heat is generated after a long period of time on
the spindle. , Then the spindle surface temperature will rise, if the
temperature is too high, it will directly affect the normal operation of
the spindle.
Therefore,
in order to ensure that the temperature of the spindle in its
affordable range, before use, according to the actual use of the need to
determine the appropriate rated temperature, and if the motor spindle
surface temperature is too high, the machine will automatically use some Way to reduce the temperature, for example, in general, it can
be forced to reduce the temperature of the oil used for circulation,
with the electric spindle temperature will soon be reduced.
