1.影响轴承寿命的因素滚珠轴承的内径和外径一般要由涡轮增压器的具体结构和尺寸来决定。与此同时,还须考虑表1所示的寿命影响因素,以确定最佳的轴承内部形状及尺寸。减小滚道曲率比,赫兹压应力下降,计算寿命长,但实际上高速时却因旋转滑动增加而使发热和磨损增大。 1 factors that affect the bearing life Ball bearing diameter and outer diameter generally by turbocharger specific structure and size to decide. In the meantime, consider the life factors shown in Table 1 to determine the best bearing internal shape and size. Reduced raceway curvature ratio, Hertz compressive stress decreased, the calculation of long life, but in fact at high speeds due to increased rotation and sliding heat and wear increases.
