螺旋传动

This text design one available in grindings the cylinder spiral slot the Z direction advance to the organization has carried on detailed mechanical design and transmission system design to the organization to Z advance.

本文设计了一台可用于磨削圆柱体螺旋槽面的数控机床的 Z 向进给机构，对 Z 向进给机构进行了详尽的机械设计、传动系统设计。

However, a disadvantage of worm gearing is the high sliding velocities across the teeth, the same as with crossed helical gears.

但是，蜗杆传动装置的一个缺陷就是，同交叉轴螺旋齿轮一样，两者在牙口之间都会产生很高的滑动速度。

With the continuous drive of the screw, the liquid will press from a seal cavity to another cavity in a spiral manner until it is pressed out of the pump body finally.

随着螺杆的连续传动，液体以螺旋形方式从一个密封腔压向另一个密封腔，最后挤出泵体。

Be familiar with design of gears, gear rack, screw spindle, shaft, spring, bearing and etc.

Featured drum by drum machines, rack, screw conveyer, the collection trough, as well as parts and other gear.

滚筒精选机主要由清选滚筒、机架、螺旋输送器、收集槽以及传动装置等部分组成。

Its mating gear is called a worm gear, which is not a true helical gear.

他的对应的齿轮叫做蜗杆传动装置，他并不时严格意义上的交叉轴螺旋齿轮。

A helical gear is one of the important transmission elements in a machine system and often used for parallel axes gearing.

螺旋齿轮为传动系统中重要机械元件之一，常被使用於平行轴齿轮组上。

Planetary gear differential is the most important part in horizontal screw decanter centrifuge which can decides the operational capability of centrifuge.

差速器是卧式螺旋离心机中最重要的传动部件，其性能和质量往往决定着整个机器的工作能力，而振动问题是离心机械常见的问题，对其进行计算是非常必要的，本文主要是就这两方面进行研究分析。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
