EI Balance. Balancing software

 

EI-1000 Balancing machine is ideal for almost all kind of rotating parts weighting between 20 and 1000 kg such as rollers, crankshafts, motor rotors, mills among others. EI-1000 Balancing machine uses a soft bearing system built using light and resistant materials in order to decrease inertia.

Features
  • Single and two planes balancing.
  • Variable speed (Optional with an inverter).
  • Adjustable pulleys.
  • Three liberty axis for each pedestal to allow free movements.
  • Manual adjust for power transmission and supports distance.
  • Bearing based soft bearing system to avoid mechanical looseness.
  • Axial supports.
  • Cantilever Bearing support.
  • Easy calibration.
  • Solid state piezoelectric sensors integrated to avoid corrosion and damages.

Software

Measurable parameters:

  • Max Amplitude
  • RMS
  • Tachometer
  • Polar Graphs
  • Time domain signal
  • FFT (Frequency domain)
  • Mils/um, inch/s, mm/s, G, mm/s2

These parameters allow the user to have a complete description of the vibration.

FFT calculations

Fast Fourier Transform, The EI-BALANCE uses the FFT to perform all its calculations. The resolution is settable as well as the average values in order to increase balancing precision.

FFT

  • Frequency accuracy of 99.9% with a 10 seconds recording length.
  • Window settable according to the needs.
  • Harmonics tools.
  • 1600 points on real time and 1 000 000 after recording.

 

 
Balancing Calculator
Balancing Calculator

EI-BALANCE has a single and two plane balancing calculator that works with the influence coefitients method with 2 trial masses. No need to set the weight of the rotor and its dimensions.

 

Functions

  • Single plane balancing
  • 2 Plane balancing, split weights
  • Combined weights, drill depth
  • Plates sizes, trial mass calculator
  • Radius change, serial balancings (no trial mass needed, for single plane)
  • Residual unbalance calculator

EI-1000 Roller working supports have bearings
in a pendulum and cantilever configuration to
avoid damages to the shaft, increasing the
sensitivity of the whole system.
