    • A method of assembly for a planetary gear train wherein long front gears of stepped long pinions are applied with markings on the end surfaces of tooth forms, the middle grooves of the second and third stepped long pinions are respectively provided with an assembling pin hole in the position at an angle 180 degrees opposite to said markings, and the long rear gear of the first stepped long pinion is provided with a spot facing on the end surface corresponding to the marking, the process comprising preparing an assembling jig composed of carrier-fixing plates at an angular interval of 120 degrees on the center of a boss portion, a spot-facing plate provided in the direction rotated 15 degrees on the center of the support shaft located between said carrier-fixing plates, and control pins supported on pedestals; assembling the stepped long pinions by inserting the control pins into assembling pin holes so that the markings on the second and third stepped long pinions are pointing to the same direction as that of the marking of the first long pinion positioned by the spot facing plate.
    • 一种用于行星齿轮系的组装方法,其中阶梯式长小齿轮的长前齿轮在齿形端面上施加有标记,第二和第三阶形长小齿轮的中间槽分别在其中设置有组装销孔 位置与所述标记相反180度的角度,并且第一阶梯式长齿轮的长后齿轮设置有面对与标记对应的端面上的点,该方法包括制备由载体固定板构成的组装夹具 在凸台部分的中心处以120度的角度间隔设置在位于所述载体固定板之间的支撑轴的中心上沿旋转15度的方向设置的面对板和支撑在基座上的控制销; 通过将控制销插入组装销孔中来组装阶梯式长小齿轮,使得第二和第三阶梯式长小齿轮上的标记指向与由面对板定位的第一长小齿轮的标记相同的方向。
