电主轴用角接触球轴承关键技术的研究

Study on the Key Technologies of Angle Contact Ball Bearing Using for High Speed Motor Spindle

角接触球轴承作为高速电主轴的核心部件,其性能直接影响电主轴的性能。通过选择合理的配置形式和预加载荷,选择合适的润滑方式及选用新型材料,可提高角接触球轴承的寿命和电主轴的寿命。

As the core parts for high speed motor spindle, the properties of angle contact ball bearing has effect on the properties of motor spindle.Through choosing the rational disposition form and adding the load in advance, the suitable lubricated method and the new materials for use can improve life - span of angle contact ball bearing, and raise lifespan of motor spindle.
