Extent of Usage in Stationary Measurement Systems

Statistics on the consumption structure of balancing devices manufactured by Vibromera reveal that approximately 30% of these devices are purchased for stationary measurement and computational systems in balancing machines or stands.

Softbearing Machine Design Essentials

The design illustration indicates a mobile frame affixed to stationary stands using ribbon springs. Influenced by the centrifugal force generated by the rotor’s imbalance, the trolley can undergo horizontal oscillations relative to the stationary stand. These oscillations are measured with a vibration sensor.

Key Features of Softbearing Machines

The design of the support system achieves a low natural frequency for the trolley oscillations, ranging between 1-2 Hz. This allows for rotor balancing across a broad frequency range, starting from 200 RPM. The relative ease of manufacturing such supports makes this design highly appealing to our customer base, who often build their own specialized balancing machines.

Parameters to Consider in Support Design

One of the most critical parameters to consider in the design and manufacture of these supports is their natural oscillation frequencies. These frequencies are crucial for the accurate measurement of vibration amplitude and phase. In instances where the support’s natural oscillation frequency coincides with the rotor’s rotational frequency (resonance), precise measurements become virtually impossible.

Implications of Resonance

During the balancing of any mechanism in the resonance zone, even minor frequency changes can lead to significant instability in measurement results. This affects the accuracy of corrective weight parameters and ultimately compromises the quality of balancing. For softbearing machines, the lower limit of permissible working frequencies for the balanced rotor should exceed the support’s natural oscillation frequency by at least 2-3 times.
