Because of the fact, the bearing capacity of the whole drive cannot be developed well enough. To improve the performances of the load-capacity, transmission efficiency, and reliability of mechanical drive, we originally developed some designs of the double crank ring-plate-type cycloid planetary drive. The new-type drive keeps all the natural advantages, which is of multi-tooth mesh, small mesh angle, and hardened tooth flank of gears. Moreover, The drive does not need the special output unit as the ring-plate-type drive does, so that the rigidity of the output shaft becomes much higher. Since the tumbler bearing is placed outside the cycloidal gear, the size of the bearing is no longer restricted to any extent.

为大幅度提高其承载能力、传动效率和可靠性诸指标，我们创新研究出来的多种结构双曲柄环板式针摆行星传动，其特点是不仅保留着原摆线针轮行星减速器同时啮合齿数多，总法向力与总圆周力间夹角小，摆线轮与针轮齿均为硬齿面等本质上的优点；而且又具有环板式传动省去输出机构且输出轴刚性好，转臂轴承移至行星轮外，从而传递的转矩可以成倍提高的优点。

Structure form adopts converse triangle beam double-hole connection welded by general electric trolley wall plate and steel plate, connection shaft, triangle beam bottom is connected with girder by nut and thrust bearing, triangle beam could rotate 360 degrees horizontally, thus realize whole set electric trolley horizontal rotation, largely reduce curve track curvature radius of electric hoist traveling mechanism.

结构形式采取通用电动小车墙板与一个钢板和连接轴组焊的倒三角形吊梁双孔连接，三角吊梁下面通过螺母及推力轴承与一个横梁连接，三角吊梁相对横梁可在水平方向做360度旋转，从而实现电动小车的整体水平方向转动，大大减小了电动葫芦运行机构弧形轨道曲率半径。

To meet a Soviet Naval Air Force specification in the late fifties for an antisubmarine helicopter for ship or shore-based use, the Kamov bureau developed a helicopter powered by twin turbines installed side-by-side above the cabin, which drove two three-bladed coaxial, contra-rotating rotors as on their other aircraft.

为了满足其反潜直升机的船舶或岸上使用前苏联海军空军在50年代末规格，卡莫夫局研制的双涡轮机驱动的直升机机舱内安装以上，其中开车边按边两个三刃同轴，禁忌旋转的转子上的其他飞机。

Moreover, sum up the modeling method and step for tap;The paper focus on the tapping speciality of screw tap, and the influence between geometrical parameters and cutting performance, targeting the minimum tapping and axial force, the optimum design of geometrical parameters is done, especially the flute shape.

论文重点研究了螺旋槽丝锥的攻丝特性及其几何参数对切削性能的影响，基于最优设计原理建立了攻丝扭矩最小及轴向力为零的双目标非线性优化模型，并利用Matlab软件，对螺旋槽丝锥的几何参数，尤其是丝锥容屑槽槽形，进行了优化，根据优化结果建立了丝锥的三维CAD造型。
