Methods for vibration diagnosis of wheel blocks, wheel sets

Methods for vibration diagnosis of wheelset bearings of the Steam locomotives were of the society BALTECH the end of 90-s effective introduced. Our specialists have different methods for reliable Function of the wheel-drive and Wheel-Getriebeblöcke of the traction unit developed.

The difficulty of the diagnosis of Diesel or Electric locomotives is that the wear of the Wheelset roller bearing and the Spurlager in the operation of the traction unit by the Stress is different, because of locomotives in front of the Lokomotivwechsel in different directions have different runtime can run.

For the diagnosis to be locomotives in the Lokomotivbetriebswerk gewägt (although with a Hebewinde lifted), and the Load on wheel-drive and wheel-Getriebeblöcke makes a half turn in the Contrast to the load in the operating state.

In the context of the BALTECH at that time developed methods for vibration diagnosis of the wheelset was the speed increase over 120/min recommended to cracks in the upper part of the outer ring of the bearings. To Alignment of the holes of the traction unit, we have the laser system BALTECH LL-9110 developed. To Monitor the temperature conditions for electric motors from wheel-drive and wheel-Getriebeblöcken as well as the diagnosis of Contactors, current collectors and electrical equipment of electric locomotives and the Monitoring of the refrigeration equipment, thermal imaging cameras are BALTECH TR-01800 recommended. To the balancing and vibration diagnosis of the wheel sets have we are the new diagnostic system BALTECH VP-3470 developed.

Technical data and measuring values of BALTECH VP-3470:

1) Measured Values For Acceleration, Velocity, Schwingweg

2) detector for RMS, peak value, peak-to-peak value (Amplitude), Peak Factor, Excess

3) number of averages - 1-100

4) frequency ranges for the measurement of vibration - ISO: 2...200Hz, 2...1000Hz, 10...1000Hz, 10...2000Hz, in addition: 10...10000 Hz.

We invite technical experts to our seminars and courses ТОР-103 "fundamentals of Lagerschwingungsdiagnose for Industrial and axles of locomotives".
