<P>PROBLEM TO BE SOLVED: To provide a turbine or a compressor, in particular for a turbo compound system capable of forming an external bearing gap between an external circumference of a play bush having larger amount of play than that of an internal bearing gap and an internal circumference to which a housing opposes. <P>SOLUTION: This turbine, in particular, an exhaust gas power turbine, has a turbine wheel 2 on a first end part or in a scope of the first end part, includes a driving shaft 1 having a gear wheel 3 on a second end part or in a scope of the second end part, and the driving shaft forms the external oil filled bearing gap 7 and an internal oil filled bearing gap 8 for the driving shaft and is mounted by using the play bush 5. The amount of play of the bearing in the external bearing gap being the value obtained by dividing a difference between inside diameter of the bearing housing and outside diameter of the play bush by the outside diameter of the play bush is smaller than amount of play of the bearing in the internal bearing gap being the value obtained by dividing a difference between inside diameter of the play bush and outside diameter of the driving shaft by the outside diameter of the driving shaft. <P>COPYRIGHT: (C)2011,JPO&INPIT |
