    • A vacuum apparatus of rotary motion entry is disclosed, which comprises: a shaft sleeve, disposed on a cavity wall of a vacuum system; a rotary shaft, ensheathed by the shaft sleeve; and a transmission set, connected to the rotary shaft for driving the same; wherein, the rotary shaft is disposed passing through a hole formed on the base of the shaft sleeve while there are a first bearing, a second bearing, a sealing ring and a shaft seal being arranged separately inside the hole. Moreover, the shaft seal has a flake-like lip flange formed extending toward the center of the hole, that is capable of being extended away from the vacuum system by the inserting of the rotary shaft into the hole, and thereby, enabling the lip flange to engage with the rotary shaft tightly by the atmospheric pressure and thus isolating the outside world from the vacuum system.
    • 公开了一种旋转运动进入的真空装置,其包括:设置在真空系统的空腔壁上的轴套; 旋转轴,由轴套套管; 以及与驱动该旋转轴的旋转轴连接的变速器组; 其特征在于,所述旋转轴设置成穿过形成在所述轴套的基部上的孔,同时在所述孔内分开设置有第一轴承,第二轴承,密封环和轴密封件。 此外,轴密封件具有形成为朝向孔中心延伸的片状唇缘凸缘,其能够通过将旋转轴插入孔而远离真空系统延伸,从而使得唇缘凸缘 与大气压力紧密地与旋转轴啮合,从而将外界与真空系统隔离开来。
