固定轴

The medium is water and the inner flow field of vortex pump is rotating flow with constant angular velocity, three dimensional, and incompressible turbulent flow.

数值模拟计算选取工作介质为清水，并认为是牛顿流体且局部各向同性；认为旋流泵的内部流场是以定常角速度绕固定轴的旋转流场，属于复杂的三维不可压湍流流动。

Entrusted to the structure of double pulley as shown in Figure 3, by the guide pulley, a small guide pulley, a fixed shaft and bearing components.

复式托带轮的结构如图3所示，由大导轮、小导轮、固定轴及轴承座组成。

Fixed occasional double pulley block fixed at both ends by bearings.

复式托带轮固定轴两端由轴承座固定。

The invention is useful for converting current bogies with fixed axles into bogies with transversely displaceable axles.

本发明有助于将固定轴的现行转向架改装成带有轮轴可横向移动的转向架。

A system of epicyclic gears in which at least one wheel axis itself revolves about another fixed axis .

至少一个轮轴围绕另外固定轴旋转的传动装置系统。

According to the concentrating extent of coordinatevalue, fixed axis is identified automatically, so delaminating data is realized.

根据坐标值的集中程度来自动识别固定轴，实现数据的分层。

When the large rotating arm rotates, the transmission gear is driven to rotate around the fixed gear to rotate the planetary gear, which drives in turn the small rotating arm to rotate in the direction opposite to the large rotating arm, so that the shaft of the small rotating arm reciprocates across the rotation center of the large rotating arm.

当大旋臂旋转时，传动齿轮受到驱动沿固定齿轮周转并带动卫星齿轮转动，卫星齿轮带动小旋臂作与大旋臂反向的旋转，从而使小旋臂上的固定轴随着大、小旋臂的旋转不断往复越过大旋臂的旋心作直线运动。

Disc in the valve body around a fixed axis of the valve, called the Butterfly.

蝶板在阀体内绕固定轴旋转的阀门，叫蝶阀。

In common with other similar systems in UK, this has 10 independent scanning axes and 5 motorised fixture axes.

与英国的其他系统相似，该系统有10个独立的扫描轴和5个固定轴。

This paper gives a thoeretical analysis on the standard currently adopted in China for the widening of railway track gauge on curves, and points out that this atandard does not tally with the railway oparational actuality, the calculation data used are not in conformity to the present rolling stock conditions in this country and that the marginal radius and the amount prorided for the widening of curved track gauge are on the large side.

本文对我国现行曲线距轨加宽标准进行了理论分析，指出它脫离运营实际，而采用计算数据又不符合我国现有车辆情况，加宽起始半径和加宽值都偏大。提出在理论上比较切合实际的计算方法是车辆按力学自由內接条件计算；机车和少数固定轴距大的车辆，按最小运营半径条件检算，制订我国的曲线轨距加宽新标准。
