Title:
【発明の名称】Cu系焼結合金製変速機用同期リング
Document Type and Number:
Japanese Patent JP2623777
Kind Code:
B2
Abstract:
PURPOSE:To improve the initial comformability of the title ring and to suppress the generation of its abnormal wear by specifying the content of Sn, Mn and Si in a Cu-series sintered alloy and specifying porosity in the part of the contacting and sliding surface with mating members. CONSTITUTION:A synchronous ring is formed with a Cu-series sintered alloy contg., by weight, 3 to 10% Sn, 1 to 10% Mn and 0.3 to 5% Si, contg., at need, one or both of 0.5 to 9.5% Zn and 0.2 to 5% Al and/or 0.1 to 6% of one or more kinds among Fe, Ni and Co and/or 0.1 to 4% of one of more kinds among Mo, Cr, Nb, Ti and V and the balance Cu. The porosity at least in the part of the contacting and sliding surface with mating members is regulated to 0.1 to 10vol.%. The synchronous ring has high strength to be required, furthermore has less change in the initial and late friction coefficient even under the condition of high bearing pressure and shows excellent wear resistance.
