对铁路专用内燃、电力机车牵引电机抱轴瓦油推广应用中所普遍关注的几个问题作了回答。对抱轴瓦油研制背景、成果水平及铁道部推广使用的意义进行了综述;对抱轴瓦油标准及其修订情况、油品的重要特性及添加剂配方特点作了系统介绍;还从流体润滑状态方面,简述影响抱轴瓦润滑效果的主要因素;说明了普遍关心的未经铁道部鉴定的、非定点厂生产的“抱轴瓦油”,即使符合标准也不能使用的理由,提出了推广应用中的注意事项。
The railway dedicated internal combustion, electric locomotive traction motor axle oil for promotion and application of general concern in a few questions answered. The research background of axle bearing oil, the achievement level and the significance of popularizing the use of the Ministry of Railways were reviewed. The standards of axle-bearing oil and its revision, the important characteristics of oil products and the characteristics of additive formulation were systematically introduced. , Briefly describes the main factors that affect the lubrication effect of the axle bearing bush, and illustrates the reasons for the widespread concern that the “axle-mounted bearing oil” produced by non-fixed-point factories that have not been identified by the Ministry of Railways can not be used even if they meet the standards. Precautions.
