Online Load Operating Mode of Oil Film Bearing in High Speed Wire Rolling Mill

摘要

To study the mechanism of burnt damage of oil film bearing in high-speed wire rolling mill,reasonable tempera- ture sensors are designed and calibrated,pressure block of rolling mill has been transformed into pressure sensors.Online tempera- ture and load of oil film bearing in a domestic precision rolling F15 have been tested.Consequently,a large sum of valuable test data was obtained.The distributions rules of pressure and temperature under continuous online rolling state are recorded in detail. Theoretical and experimental results are beneficial to damage mechanism of oil film bearing,thus its service life could be pro- longed.Moreover,such results could provide an important reference for online test and control.
