Title:
ALUMINUM ALLOY-MADE FLOATING METAL BEARING
Document Type and Number:
Japanese Patent JP2019094523
Kind Code:
A
Abstract:
To achieve suppression of self-excited vibration and reduction of undesired noise by noise by achieving weight saving of a bearing by using aluminum of which specific gravity is small, increasing followability of rotation and reducing turbo lag for solving a problem to reduce bearing loss.SOLUTION: There is adopted a configuration made from an aluminum alloy composed by silicon (Si), iron (Fe), copper (Cu), manganese (Mn), magnesium (Mg), zinc (Zn), titanium (Ti) and other various and other balance of aluminum (Al) by weight ratio, and born by bearing housings becoming receiving parts of floating metal bearings of both of a suction side and an exhaust side as an integrated structure, for a raw material of a sliding bearing.SELECTED DRAWING: Figure 1
