七、RCT轴承的性能与寿命 为了研究和确定轴承的性能和某些规律,对轴承要做性能与寿命试验。性能试验除要检测轴承的主要尺寸精度、滚子及套圈滚动面的光洁度和硬度外,还要检测轴承的回转精度、运转性能、保持架回转精度、密封的回转性能及轴承落下试验等项目。 轴承的性能和寿命试验可在试验台上或 Seven, RCT bearing performance and life In order to study and determine the performance of bearings and some of the laws of the bearing performance and life to do the test. In addition to testing the performance of the main bearing size accuracy, roller and the ring rolling surface finish and hardness, but also testing the bearing slew accuracy, running performance, cage rotation accuracy, seal the rotary performance and bearing drop test items . Bearing performance and life test can be on the test bed or
