Two-Station Automobile Generator Rotor Automatic Balancing Machine
1. Equipment Description
Zero Dynamic’s Two Station Automobile Generator Rotor Balancing
Machine High Precision Automatic Balancer is an automatic balancing machine developed for client's
automotive generator rotors, compatible with generator rotors with
diameter 69.3mm - 10 8.7mm, shaft length range 135-154mm, weight up
to 5kg (rotors with bearings can also be measured), balancing
correction method is double-plane diagonal cut drilled holes
(number of de-weighting holes can be set for the same claw pole).
The angle of the de-weighting head can be adjusted in the range of
30-60° to meet the balancing correction requirements of different
rotor sizes.
Zero Dynamic’s Two Station Automobile Generator Rotor Balancing Machine High
Precision Automatic Balancer consists of mechanical main body, balance measuring system,
electrical control system, automatic testing and de-weighting
device, dust-absorbing device, safety protection mechanism and
other components. The two pedestals of the measuring station can be
adjusted on the base according to the supporting distance. The
support rollers on the pendulum frame are removable, which can be
adapted to different support methods such as roller support and
bearing support. The equipment adopts the latest dynamic balancing
software of Zero Dynamic, which includes dynamic balancing
measurement, data storage (including initial unbalance and
allowable residual unbalance), qualification judgment, automatic
drilling correction, and uploading of measurement results.

4. Main Features:
4.1 Soft bearing measuring structure and high-precision vibration
sensor, good vibration resistance and repeatability.
4.2 The position of the measuring station pedestals is adjustable,
thus compatible with the dynamic balance measurement of workpieces
of different spans. The support rollers on the pedestal are
removable, which can be adapted to roller support, bearing support
and other support methods.
4.3 Lower bracket belt drive, convenient for docking with
manipulator to load and unload materials to achieve automated
production.
4.4 The angle of the de-weighting power head can be adjusted in the
range of 30-60° to meet the balancing correction requirements for
rotors of different sizes.
4.5 The self-developed dynamic balancing software has the functions
of dynamic balancing measurement, qualification judgment, data
saving, querying, exporting, printing, uploading of measurement
results, etc. It also supports amplitude display.
4.6 The dynamic balancing software comes with alarm prompts, which
is convenient to find the fault location.
4.7 The equipment can be connected to the MES system and can be
added with specified functions as required by clients.
