Abstract

PURPOSE:To prevent an accident by detecting a fault of a bearing in its early stage by measuring oil film pressure, metal temperature and an acoustic signal at several points. CONSTITUTION:The outer circumferential surface of a bearing 2 supporting a journal 1 forms a spherical seat 3, and alignment is adjusted through an adjustment ring 4. In a bearing slide surface 9, two pressure measurement holes 10 are made axially and two holes are also made circumferentially. On a bearing flank 8, a pressure sensor 12 is provided. In addition, a temperature sensor 7 is buried in the vicinity of the pressure sensor 12 and on the flank 8, an acoustic sensor 13 is provided. An oil-film pressure and a metal temperature signal from the pressure sensor 12 and temperature sensor 7 are inputted to the signal input device (PI) of an operator 18, and a signal from the acustic sensor 13 is inputted to the PI17 through amplifiers 19 and 20. On the other hand, operation conditions 23, such as a rotational frequency, and bearing oil temperature 24 are inputted to the PI17 through another system.
