一、概述在轴承破损过程中,其全部零件会失去原有形状,并被激烈加热,因此,排除了进行某种金相和度量检查的可能性。为确定因热装轴承破坏而导致轴箱部件破损的期限(轴承部件寿命)而进行的专门研究,弄清了如下一些基本特征:轴承有某些毛病(内环松驰、内环断裂、保持架定心表面磨耗及断裂、内环部分或全部破损)和轴箱端部紧固缺陷(螺母松缓、M20端垫固 I. Overview In the process of bearing damage, all of its parts will lose their original shape, and was heated intensely, therefore, ruled out the possibility of some metallographic and measurement checks. In order to determine the deadline (the life of the bearing components) due to the damage of the hot-loaded bearing, the following basic features were clarified: Some problems with the bearing (loose inner ring, broken inner ring, Rack centering surface wear and tear, the inner part of the ring or all of the damage) and the shaft end fastening defects (nuts loose, M20-side pad
