副轴

Hence, the countershaft and all its rigidly connected gears are in motion whenever the drive shaft revolves.

因此，当驱动轴旋转时，副传动轴及与其刚性连接的齿轮都处于运动中。

Step 1: Center the secondary mirror on the axis of the focuser drawtube.

把副镜中央置于调焦伸缩管的中轴。

Inflorescence rachis indumentum purple; leaf blade base shallowly cordate; epicalyx lobes ca.

花序轴毛被紫色；叶片基部浅心形；大约1/2的倍于花梗的副萼裂片。

Step 2: Here you adjust the tilt of the secondary mirror to aim the focuser 's axis at the center of the primary.

现在你已经调整了副镜的倾斜程度，把调焦座的中轴已经对准了主镜。

And in the long run the situation is relatively stable, with the type of impeller pump to force smaller, and can be set in the cover before and after the deputy leaves.

且在长期运行中情况比较稳定，采用该型式叶轮的泵轴向力较小，且可以在前后盖板上设置副叶片。

Also in order to maintain the main impeller axial force balance, have to set up a vice-impeller structure, it can reduce the pressure sealed chamber so that the axial force pump and mechanical seal life expectancy are greatly increased.

另外为了保持主叶轮轴向力的平衡，须设置一个副叶轮结构，它能降低密封腔的压力，使电泵的轴向力及机械密封的寿命均大大提高。

Also in order to maintain the balance of the main impeller axial force, shall be a Vice-impeller structure, it can reduce the pressure sealed chamber, so that the axial force pump and Magnetic pumps mechanical seal life are greatly increased.

另外为了保持主叶轮轴向力的平衡，须设置一个副叶轮结构，它能降低密封腔的压力，使电泵的轴向力及机械密封的寿命均大大提高。

The flexible projecting shaft is long, can reduce rigidity of transmission system greatly, improve joggle state of gears, reduce failure rate of gear pair and transmission system, and enhance reliability of whole machine.

所述柔性悬臂轴较长，能够显著降低传动系统的刚度，改善齿轮的啮合状态，降低齿轮副乃至传动系统的故障率，提高整机可靠性。

A C frame a larger diameter reflecting telescope, through the transformation with different sub-mirror, access to the main focus of the system, Cassegrain system and the fold-axis system.

一C架较大口径的反射望远镜，通过变换不同的副镜，可获得主焦点系统、卡塞格林系统和折轴系统。

Leakage in the initial observation to determine the basis of the leakage site, and then manually set car observation, if the leakage were no significant changes in static and dynamic sealing ring problem; such as the disk when there are significant changes in leakage can be concluded that the dynamic , static friction ring problems; such as leakage of medium along the jet axis, w你好le moving most of Central ring problems, leakage to the surrounding medium or from the water spray cooling holes in the leakage, the seal ring for static failure.

杂质泵安装静试时泄漏机械弥缝安装调试好后，一般要进行静试，察看泄漏量如泄漏量较小，多为动环或静环弥缝圈存在问题；泄漏量较大时，则表白动、静环磨擦副间存在问题在开端察看泄漏量、判断泄漏部位的根蒂根基上，再手动盘车察看，若泄漏量无明显变化则静、动环弥缝圈有问题；如盘车时泄漏量有明显变化则可下定论是动、静环磨擦副存在问题；如泄漏介质沿轴向喷洒，则动环弥缝圈存在问题居多，泄漏介质向四周喷洒或从水冷却孔中漏出，则多为静环弥缝圈失效此外，泄漏通道也可同时存在，但一般有主次区分，只要察看细致，认识结构，一定能正确判断
