我国铁路客车采用滚动轴承已有十多年了,到目前为止,国内客车保有量中,能够改用轴承的约有50％已装用了滚动轴承,而新造客车早已全部采用滚动轴承。为便于普及轴承应用方面的基本知识,重点介绍一下客车轴箱用短圆柱滚子轴承的负荷与寿命计算,轴承的润滑、保管、防锈等方面的资料。 Rolling bearings have been used in China’s railway passenger cars for more than ten years. So far, about 50% of domestic passenger cars have been equipped with rolling bearings instead of rolling bearings, and the newly built passenger cars have all adopted rolling bearings. In order to facilitate the popularization of the basic knowledge of bearing applications, focusing on the bus axle box cylindrical roller bearing load and life calculation, bearing lubrication, storage, rust and other aspects of the information.
