<P>PROBLEM TO BE SOLVED: To solve the problem of nonexistence of a slide member combination capable of intermittent unlubricated sliding for a long period of time and sliding in a liquid, a gas and a gas-liquid mixture fluid containing slurry such as earth and sand in the slide member combination of a slide bearing for use in a rotary machine. <P>SOLUTION: As a slide bearing combination slide member operated in an unlubricated condition and in the fluid containing the slurry, a bearing stationary side slide member is made of a metal with a great coefficient of thermal expansion with its internal sliding surface having a structure wherein a passage for cooling liquid is not provided. In a rotation shaft sleeve side slide member, a carbon fiber fabric material as a carbon material with a bulk ratio of at least 50% is used so as to form layers in the direction of a rotation shaft by means of laminate molding, and a carbon fiber fabric lamination carbon-based composite material with a small coefficient of expansion is used wherein the end surface of carbon fiber is exposed on the slide surface. The problem is solved as described above. <P>COPYRIGHT: (C)2012,JPO&INPIT |
