润滑

A new infinite gas-lubiicated journal bearing with active controlled restrictor is proposed in order to remedy the defects of several existing infinite stiffness at abroad in construction, manufacture and adjusting, which combining surface-restriction with active controlled restriction, make the static and dynamic effect both better.

针对目前国外几种无穷静刚度气体润滑轴承结构复杂、制造难度大、调整困难的不足，本文提出了一种主动控制节流无穷静刚度气体润滑轴承，将表面节流与主动控制节流相结合，使轴承动、静压效果同时获得较好的发挥；利用浅腔及锯齿形多槽结构产生较强的楔形动压效应，提高轴承的静态和动态性能；利用主动控制节流器对轴承进行压力反馈主动控制，提高轴承的承载力、刚度，并在一定载荷范围内，使轴承刚度为无穷大。
