    • The present invention relates to a micro gas turbine with a compact structure. More specifically, a sub journal bearing is placed between a thrust collar and a wheel of a compressor which means the bearing is placed around the thrust bearing at a compressor so that the whole length and weight of a rotator are reduced to form the compact structure. A pair of main journal bearings separated from each other at a certain distance is placed between a hollow shaft and a sleeve. The main journal bearings fully support a shaft between the compressor and turbine wherein dynamic pressure is heavily applied caused by rotation in order to maximize safety. For the purpose, the present invention comprises a turbine wheel; a tie shaft which one end part is connected to the turbine wheel; a compressor wheel which is separated from the turbine wheel to be inserted into the tie shaft; a thrust rotor separated from the compressor wheel to be fixed to the end part of the tie shaft; the thrust collar placed on a part of the outer surface of the thrust rotor; and the sub journal bearing equipped between the thrust collar and the compressor wheel.
    • 本发明涉及一种结构紧凑的微型燃气轮机。 更具体地说,副轴颈轴承放置在推力环和压缩机的轮之间,这意味着轴承以压缩机的方式放置在推力轴承周围,从而使转子的整个长度和重量减小以形成紧凑的结构。 在一定距离内彼此分离的一对主轴颈轴承放置在空心轴和套筒之间。 主轴颈轴承完全支持压缩机和涡轮机之间的轴,其中动态压力由于旋转而被大量施加,以便最大化安全性。 为此,本发明包括涡轮机轮; 一个端部连接到涡轮机叶轮的连接轴; 压缩机叶轮,其与涡轮机叶片分离以插入连接轴; 与压缩机叶轮分离的推力转子固定在连接轴的端部; 推力轴环放置在推力转子的外表面的一部分上; 轴承和压缩机轮之间配备的子轴承轴承。

    • PURPOSE: An air foil bearing having a viscoelastic foil is provided to allow a rotating member to rotate at an increased R.P.M by damping vibration generated from the rotating member. CONSTITUTION: An air foil bearing includes a bearing housing(10a), a top foil(10e), a viscoelastic foil(10d), a bump foil(10c) and a core foil(10b). An air lubricant layer(10g) is positioned between the top foil and a rotating shaft(10f). The top foil(10e) is formed at an upper surface thereof with a solid lubricant coating surface so that a friction between the top foil(10e) and the rotating shaft(10f) is reduced when the rotating shaft(10f) is rotated. One end of the top foil(10e) is supported by the bearing housing(10a) through a pin(10h). The viscoelastic foil(10d) is installed at a lower portion of the top foil(10e).
