High speed bearing data This dataset is taken from a 2MW wind turbine high speed shaft with a measurement taken for 50 consecutive days (the 5 download links below contain 10 days of data each). The bearing has an inner race fault which is increasing in severity across the 50 day period. The high speed shaft is driven by a 20 tooth pinion gear. See publication link for further details. http://data-acoustics.com/wp-content/uploads/2014/06/HS_bearing_meta_data.xml http://data-acoustics.com/wp-content/uploads/2014/06/hs_bearing_1.zip http://data-acoustics.com/wp-content/uploads/2014/06/hs_bearing_2.zip http://data-acoustics.com/wp-content/uploads/2014/06/hs_bearing_3.zip http://data-acoustics.com/wp-content/uploads/2014/06/hs_bearing_4.zip http://data-acoustics.com/wp-content/uploads/2014/06/hs_bearing_5.zip https://www.phmsociety.org/sites/phmsociety.org/files/phm_submission/2013/phmc_13_006.pdf Eric Bechhoefer ebechhoefer@gmail.com March/April 2013 High speed bearing dataset by Eric Bechhoefer is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License. http://data-acoustics.com/?p=260 Increasing inner race bearing fault 2 MW 1800 rpm 0.42 x (shaft speed) 6.72 x (shaft speed) 9.47 x (shaft speed) 1.435 x (shaft speed) 1 (sensor) 97656 Hz 6 seconds 'g' Radial Acceleromter 2 (tach) 2/rev (constant angular sampling) 40 seconds (approximately) time (s)
