在防止车轮裂损的措施中,车轮维修保养的检查标准之一是,“更换因制动热等影响而出现辐板涂层剥离的车轮”。这里所说的涂层剥离,是指发生在从轮辋凸缘部分至车轮辐板距轮心340毫米处的整个圆周方向上的涂层胀起和剥落现象。另外,车轮涂漆是定在段修期间进行(轮修时,根据涂层使用情况,对局部进行涂装修补),涂料是JRS(日本国铁标准)66054—ID—15AR9A的黑色调合漆。从以往车轮的裂损和龟裂事故米看,这些车轮都是未经热处理的,都是采用合成闸瓦制功车轮,涂层的剥离和胀起大都很明
Among measures to prevent the wheel from being cracked, one of the inspection standards for wheel maintenance is to “replace the wheel with the peeling of the web by the influence of brake heat.” The peeling of the coating as used herein means coating swelling and peeling occurring in the entire circumferential direction at a distance of 340 mm from the rim flange portion to the wheel web. In addition, the wheel paint is scheduled to be carried out during the repair segment (wheel repair, according to coating the use of local painting repair), paint is JRS (Japan National Railway standard) 66054-ID-15AR9A black paint . From the past, the wheel cracks and cracked meters look, these wheels are not heat-treated, are made of synthetic brake shoe made of power, coating stripping and swelling are mostly clear
