传动比

The combination of high gear ratio and long stroke can drain an entire air system unless the air supply system is specially designed to accommodate this type of actuator.

高传动比和长冲的结合可以排出整个系统空气，除非空气供应系统为适应这一类型驱动而进行特殊设计。

2At drive than will certainly,driven gear, while having the more same sizes, hyperboloid have diameter not larger of gear wheel not initiative than corresponding spiral awl gear wheel, intensity and bigger initiative gear wheel axle and bearing rigidity of higher teeth of a cogwheel.

螺旋角是指在锥齿轮节锥表面展开图上的齿线任意一点A的切线TT与该点和节锥顶点连线之间的夹角。在齿面宽中点处的螺旋角称为中点螺旋角(图5—4)。通常不特殊说明，则螺旋角系指中点螺旋角。双曲面齿轮传动比为

Also, the drive is able to transfer larger torque and power than the existing planetary cycloid drive.

其具有体积小、重量轻、传动比范围大、传动效率高、传动平稳、结构简单、传递的扭矩和功率较传统摆线针轮行星传动成倍增大等一系列优点。

So it is quite necessary to have the carding mechanism modified to solve the problems. Approaches are provided which includes redesign the driving ratio and rearrange the configuration of working parts to make worker strip doffer work effectively.

针对上述问题，本文通过分析现有的人造毛皮机的喂毛梳理机构，发现其存在的不合理配置问题，然后对其进行了改进，重新设计了梳理机构的传动比和工作部件的配置情况，使工作辊有效地实现了对道夫的剥取作用。

On the condition of "many-head" and "small drive ratio",the plane double enveloping hourglass worm can not settle the problem of undercutting and sharpening simultaneously.It has devoted to a new type hourglass worm_sphere double enveloping hourglass worm.

考虑到平面二次包络环面蜗杆传动在多头小传动比条件下根切与齿顶变尖的矛盾很难同时解决且啮合性能较差，介绍了一种新型环面蜗杆传动——球面二次包络环面蜗杆传动。

It is proven that face gear drive with high contact ratio enables to enhance load-bearing and have a good dynamic performance.

这是证明，面对高齿轮传动比使接触，以提高承载和有一个良好的动态性能。

The end face harmonic gear drive of oscillating teeth is a new type of transmission drive;it can be applied in the reducers where large speed ratio and high power is needed.

活齿端面谐波齿轮传动是一种新型的传动方式，可以应用于大传动比、大功率的减速器中。

When the teeth ratio of planetary gear is greater than 2 and transmission ratio is less than 1,the transmission will be speeded up from right to left.When the teeth ratio is less than 2,transmission will be slowed down from right to left,and when the teeth ratio is becoming close to 1,transmission ratio will trend towards infinity theorically.

当行星齿轮的齿数比大于2时，传动比小于1，传动自右到左为增速；当齿数比小于2时，传动自右到左为减速；当齿数比趋向1时，传动比理论上趋向无穷大。

In the transmission mechanism of optional drive ratio worm crank pin,the circular pitch of annulus worm changes from the function of optional drive ratio.When the annulus worm tums equably,the roll-pin crank brings shift tuming through joggling,and it can applly to dumping and turning mechanism of ladle.

变传动比蜗杆曲柄销式传动机构，其环面蜗杆的齿距是依变传动比的函数关系变化的，当环面蜗杆匀速转动时，通过啮合使滚销式曲柄产生预期的变速转动，可应用于铸造生产的铁水浇包的倾转机构。

Proocess of design is from parts chosen to related structural arrangement and size computation,and the last one is intensity computation.we can choose steering gear angle ratio reasonably so that we control po -rtably and sensitively.

通过合理的选择角传动比和力传动比来解决操纵轻便性的要求；通过合理的选择后倾角和内倾角、消除转向器传动间隙来满足转向盘和转向轮自动回正和稳定直线行驶要求；通过合理的选择转向系结构和结构布置减小运动干涉。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down
