Type YYW-30 Small universal joint drive balancing machine

     YYW-30 type balancing machine is a small size balancing machine designed and manufactured by our factory.
This machine mainly solves the problem of wind machine dynamic balancing process, meet the factory production specifications matching.
     The special small size universal joint structure solves the problem of the universal joint of the small rotor.
The balance problem between the axial drive force and the balance accuracy can be solved in the balance process.
     The machine is designed for horizontal hard bearing, universal joint drive, computer measurement, digital meter display and other general forms.

3      Introduction of main structure:
     The utility model is composed of a base, a headstock, a universal coupling, a support frame (a pendulum rack), a sensor, an electric measuring box, an electric control box, etc..
    The front motor rotates the spindle with a triangular belt, and the spindle rotates the workpiece by dragging the spindle. Unbalanced parts of the workpiece when the imbalance caused by force, forced swing pendulum vibration, and converted into electrical signals by the sensor. The signal output from the sensor is fed to the electrical measurement box. On the other hand, the reference signal generator installed in the head box will generate a pulse signal with the same speed as the spindle rotation speed. This signal is input to the sensor signal at the same time Electric measuring box, in the electronic box after the electronic circuit processing, respectively, in the digital table shows the balance on the left and right sides of the size and angle of unbalance.
