要約
(EN)
The purpose of the present invention is, with respect to a first floating bush bearing disposed on a compressor housing side and a second floating bush bearing disposed on a turbine housing side, to improve oscillation stability when a turbine rotor revolves at a high speed, reduce the number of parts, and facilitate processing and assemblability. The present invention is characterized by being provided with the following: a bearing housing (13) for a turbocharger (1), a rotor shaft (16) that passes through the bearing housing (13), a first floating bush bearing (17) interposed between the bearing housing (13) and the rotor shaft (16) and disposed on a compressor housing (12) side and comprising a first floating bush, and a second floating bush bearing (18) that has the same shape as the first floating bush bearing (17) and is disposed on a turbine housing (11) side and comprises a second floating bush (20). The present invention is also characterized in that the inner bearing width (Li) of the first and second floating bushes is formed to be smaller than the outer bearing width (Lo) by the same proportion in both bushes.
