Rotational modes are independent of the transverse support stiffnesses of the carrier, ring gear, and sun gear. Translation modes are similarly independent of the rotational support stiffnesses. Large contact ratio do not mean lower mesh force. If either the number of sun or ring gear is not multiple of planet gear, system will run effectively, with lower impaction of tooth mesh in and out.

研究表明：扭转支撑刚度的变化影响系统的转动模态，径向支撑刚度的变化影响系统的位移模态；齿轮间重合度大并不等于轮齿间的受力情况好；行星轮与内齿圈齿数不为行星轮个数的整数被时，轮齿的啮入、啮出对系统的冲击小，系统的效率高。

This text is introducing the most popular product in engeneering machine ZL30 forklift 'transmission case in the function as well we introduce the principle of the design of transmission case .together with the main parts in transmission ,such as the fluid strength ,the overdrive clutch,the structure of planet rowand so on. and in the detailed introduction ZL30 forklift the overdrive clutch and the output shaft design process, and proposed in four axes design's improvement measure.

本文主要介绍了工程机械中应用最广泛的ZL30轮式装载机的行星式变速箱的功能和总体设计思想，并介绍了其中主要零件如：液力变矩器、超越离合器、行星排结构的用途和功能，并详细的介绍了ZL30装载机中超越离合器和输出轴的设计过程，并提出了四轴设计中的改进措施。

Here's the basic difference: when the planets in our solar system first formed, they were swimming through a disk-shaped cloud of gas. Their passage roiled and compressed the gas, and the gravity of the compressed gas in turn pulled on the proto-planets.

根本的差别在于：当行星在太阳系中首次形成时，它们正漂浮着通过一片圆盘状的气体云，于是它们前进的道路受到波动同时也压缩了气体，被压缩气体的引力反过来拉住了这些初生的行星。

Bigger ships will likely not land in garages in stations or on planets, but either hover on planets, or dock to space stations via docking ports.

更大的船则很可能不会停在空间站的泊位里，或行星上，但是可以在行星表面翱翔，或者与空间站对接。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
