在内燃机车上,滚动轴承是一种极其重要的组成部件。然而,对于滚动轴承使用寿命的研究,却仍然是一项十分细致而又复杂,且涉及面较广的问题。目前我们尚处在摸索阶段。滚动轴承在内燃机车上,特别是在液力传动装置里,它是处在高温、高负荷、高转速的恶劣工况中。为了使滚动轴承有较长的使用寿命,除了要求正确的设计和选型外,合理的拆卸、安装 In diesel locomotives, rolling bearings are an extremely important component part. However, the study of the service life of rolling bearings is still a very detailed and complex, and involves a wide range of issues. At present, we are still at a groping stage. Rolling bearings on diesel locomotives, especially in hydrodynamic transmissions, are in harsh conditions of high temperatures, high loads and high speeds. In order to make rolling bearings have a longer service life, in addition to requiring the correct design and selection, the reasonable removal, installation
