    • PROBLEM TO BE SOLVED: To improve output, and to reduce rolling movement, in an internal combustion engine in which a piston 2 in a cylinder bore 3 is coupled to a crank pin 7 provided on a crank arm 8 through a connecting rod 6, the pin shaft 9 is provided eccentrically from the crank pin and rotatably supported by an output shaft 5 so as to be eccentric from the output shaft, and a planetary gear 12 non-rotatably fitted to the pin shaft is meshed with an internally toothed gear mounted coaxially with the output shaft.
      SOLUTION: When viewed in the direction of the axis of the output shaft, the axis 3a of the cylinder bore is offset relative to a reciprocating track straight line 14 connecting an upper dead center TDC and a lower dead center BDC on the crank pin 7 by passing through the center O of the output shaft, by an appropriate distance S to the side opposite to a direction A in which the planetary gear rotates.

    • 要解决的问题:为了提高输出和减少滚动运动,在其中气缸孔3中的活塞2通过连接杆联接到设置在曲柄臂8上的曲柄销7的内燃机中 如图6所示,销轴9从曲柄销偏心地设置并由输出轴5可旋转地支撑,以便从输出轴偏心,并且不可旋转地装配到销轴的行星齿轮12与内齿 齿轮与输出轴同轴安装。 解决方案:当从输出轴的轴线方向观察时,气缸孔的轴线3a相对于连接上止点TDC和曲柄上的下死点BDC的往复轨道直线14偏移 销7通过输出轴的中心O延伸到与行星齿轮旋转的方向A相反的一侧的适当距离S. 版权所有(C)2010,JPO&INPIT
