Due to the diversification of rotating machinery, vibration, noise
problems, mechanical life requirements are increasingly stringent, must
be selected for different rotating parts suitable for the respective
characteristics of dynamic balancing machine, and the corresponding
correction of the imbalance, the following simple introduces how to
select models.
Step 1: Select the dynamic wheel balancer,
the first based on the shape characteristics of the rotating work
piece, select horizontal or vertical wheel balancing machines, of
course, if you have special requirements can also be manufactured in
accordance with the actual needs of the design.
Horizontal wheel balancing machines ---- the balance of the rotor rotation axis was horizontal wheel balancer,
in general, with the axis of the rotor of the shaft or assembly
process, such as the motor rotor, machine tool spindles, rollers, fans,
turbine, turbocharger rotor, horizontal wheel balancing machine.
Vertical Wheel balancing machine ---- is the rotation axis of the
balance of the rotor on the wheel balancing machine was balanced in the
vertical state machine, generally refers to the rotor itself does not
have discoid workpiece shaft gear, a variety of automotive flywheel,
clutch, pressure plate disk parts of the assembly, brake disc, brake
drum, motorcycle clutch and magneto rotor, fan, fan, water pump
impeller, pulley, wheel, etc., I produced the PHD series of vertical
wheel balancing machines to meet specifications of the balance of the
disc-type parts, vertical-sided wheel balancing machines series applies
to the balancing of the workpiece itself does not have the shaft of the
drum-shaped parts, such as car wheels, rims, centrifuge drum
Step 2: According to the rotor drive form the ring belt drive wheel
balancing machine or gimbals balance machine or self-drive wheel
balancing machines, wheel balancing machines drag rotor transmission
mode ring with drag drag coupling and self- driver.
Circle with
drag ---- rubber ring with or silk ring with the drag of the rotor by
the motor pulley, so the lap belt to drag the rotor surface must be
smooth cylindrical surface, and advantage of the lap belt drag does not
affect the rotor unbalance, high precision balance.
Coupling
drag ---- gimbal balance machine spindle and rotor link. The
characteristics of the coupling drag is suitable for the appearance of
irregular rotor can transmit large torque, suitable for drag fans and
other air resistance of the rotor, the coupling drag the shortcomings of
coupling itself unbalance impact on the rotor (and therefore coupling
before use to balance), will introduce interference would affect the
balance of accuracy, in addition to the connection plate to accommodate
different types of rotor.
Self-driven - is the use of the power
of the rotor's own rotation. Since the drive is the minimum drag impact
on balancing accuracy, balance accuracy is up to the highest, but only
structure allows special rotor in order to use this drag way.
The third step: According to the size of the selection of the work
piece, such as the characteristic parameters of the type of work piece,
diameter, length and weight, speed, select the sizes of dynamic wheel balancing machines,
such as 5, 16, 50,160 type numbers indicate the maximum work piece
quality, generally selected digital 1 / 3-2 / 3 of the balancing effect,
the maximum or minimum can be done, but may not be able to meet the
precision of the work piece.
