Through the intermediate gear Z12, the elevator shaft's gear Z13 and shaft are driven to turn, then via friction cone clutch or planetary mechanism the drum obtains six hoisting speeds.

a、冲击钻进：将变速箱右手柄板至&卷扬&位置，变速箱Ⅲ轴齿轮Z8与Ⅳ轴的齿轮Z10啮合，经中间齿轮Z12带动升降机轴上齿轮Z13及轴旋转，通过锥形摩擦离合器或游星轮机构使卷筒获得六种提升进度

The number of strokes of the syringe plunger before the stopper is locked into the barrel rendering the syringe assembly unusable is determined by the number of detents on the plunger rod and stopper which engage the locking mechanism.

注射器柱塞在制动器锁入针筒从而使注射器组件失效之前的冲程次数，由啮合锁定机构的柱塞杆和制动器上的定位器数目来确定。

However,the design and manufacture of involutes sprockets were studied by few domestic researchers.

渐开线齿形链轮因与链条啮合时冲击小而应用于很多齿形链机构上，但是国内很少有人研究这种链轮的设计制造过程。

The composition of joint, the match form, the variation of pitch and the calculation of the lenth of this chain are analyzed quantitatively.

文中对滚动铰链机构组成、啮合形态、节距变化以及链条长度计算等作了定量分析。

Then,the engaging function is deduced,which makes it possible to study theengaging characteristics and driving capabiliites of this new type of worm gearing.

这为进而研究分析这种新型传动机构的啮合特性和传动性能提供了条件。

On the condition that the axes of two chain wheels are in the same horizontal plane, the paper considers that the mesh drive of chain and chain wheel is equal to single small angle movement of four-rod mechanism every time on tight side.

在两链轮的回转中心同处一水平面的条件下，视紧边每一时刻链条与链轮的啮合传动为四杆机构作小转角的单向运动，建立起相应的链条速度模型，并据此分析了影响链传动中链条速度波动的因素，得到了一些有益的结

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。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
