METAL BUSH, AND DRIVE DEVICE AND EMULSIFICATION DISPERSING DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide technology for improving the load bearing or a sliding wear property, wear resistance and conformability of a metal bush being a bearing member for a drive device, without generating lead. SOLUTION: The metal bush 15 uses a metal material containing copper as a main component and manganese silicate in at least a sliding facformabilitye. The mass ratio of silicon to manganese in the metal material is in a range of 66:34-53:47. COPYRIGHT: (C)2010,JPO&INPIT
