Technical requirements for the balancing of the crankshaft and the propeller shafts

Balancing of the crankshaft and the propeller shafts is usually with the special Devices of the series BALTECH HBM-7130. To Reduce Costs for the mentioned task performance, we recommend you independently simple driven attitudes must be drawn up, for this you can use our balance system BALTECH VP-3470 ratings.

The measurement range of the device BALTECH VP-3470:

- For acceleration, mm/s2 0.05...300

- Vibration velocity, mm/s 0.05...1000

- Schwingweg, mkm - 0.05 10000...

Spectral analysis in the balancing of the crankshaft and the Shafts:

- Frequencies, Hz- 200, 500, 1000, 2000, 5000, 10000

- Line numbers 400, 800, 1600

Window - Rectangular, Hanning, Blackman-Hamming Window

Dynamic range, dB, not less than 75

The Hüllkurvendetektor with Bandpass:

- 2/3 Octave, Hz - 4000, 5000, 6300, 8000

- 1/3 Octave, Hz - 4000, 5000, 6300, 8000

- 1/1 Octave, Hz - 4000, 5000, 6300, 8000

We invite all technical specialists to our technical courses TOP 102 "foundations for dynamic balancing". Assessment of the technical Condition specified Rotorausrüstung is in the first row in detection the dynamic rotor imbalance at operating speeds, or in Betriebsdrehzahlbereich.

IMPORTANT: the Dynamic force of the unbalance belong to the niederfrequentesten Störkräften, the mechanical strength of the components and in the first row of the strength of the rotor bearing performance.

Dynamic balancing is based on the reduction of vibrations in Samples of the stock in the frequency to be monitored, to the recognized Calculation or Normlagerschwingungswerte to achieve and Mechanical Strength is to be ensured.

In cooperation for the assignment of the axis of rotation and the Hauptträgheitsachse x-x differs according to TUV following types for the Rotor imbalance:

a) Static, if 2 Axes are parallel to each other are

b) Momentunwucht, the 2 axes in the Rotorschwerpunkt cut

c) Dynamic (Mischunwucht), if 2 axes outside of the center of gravity or did not match. The balance system BALTECH VP-3470 is a new Auswuchtlösung.
