Abstract:
PURPOSE:To make damage to a rotary shaft confinable to the minimum, by sticking a bearing a bearing metal being yet larger in strength, to a surface beneath a surface layer and, when this surface layer is damaged by a fire, making the bearing metal come into contact with the rotary shaft. CONSTITUTION:A layer of a bearing metal being large in strength such as lead bronze or phosphor bronze is lined, at 0.8-2.2mm in thickness, beneath a surface layer consisting of a Pb-Sn plating layer of 0.002-0.004mm in thickness, a Pb-Sn-Cu plating layer 2 of 0.04-0.06mm in thickness and a soft bearing metal Cu-Ph-Sn layer 3. When the bearing metal layer 3 is damaged by a fire or injured, the bearing metal 4 and a rotary shaft are made contact with each other, but there is no case that this rotary shaft comes into directly contact with a carbon steel back metal 5 and thereby slide motion occurs between them, never. Therefore, damage to the rotary shaft comes to be avoidable in consequence.
