传动

Increased the production lines automation level, and improve the environment with work term, pushed the business enterprise technique the advance, and this is the reason why have the shaftless driving spread to move the technique on the printing machine quick universal with applied, and this is also this text foundation theories that study that

提高了生产过程的自动化水平，改善了环境和工作条件，推动了企业技术进步，这就是无轴传动技术在印刷机械上迅速普及和应用的原因，这也是本文研究的目的，其意义还在于无轴传动技术的基础理论明显落后于工业应用，具有的优势还远远没有在工业应用中发挥出来，需要进一步研究和创新。

Now, with flexographic press manufacturers offering shaftless press designs, it clear that shaftless printing technology is making headway in this increasingly quality and quick-turn sector of the printing industry.

目前，用柔性印刷制造商提供无轴印刷的设计，很显然无轴印刷技术能够使印刷业提高传动质量，快速传动转印区域变成现实。

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。

But the involute gear exposes certain own defaults too, such as the external toothing transmission is the engaging transmission of the protruding tooth to the protruding tooth, its contact stress is big,bearing capacity is low etc.

但是渐开线齿轮也暴露出自身一些缺点，如外啮合传动是凸齿对凸齿的啮合传动，其接触应力大，承载能力低等缺点。

以起升机构的整个传动机构为研究对象，假定传动机构位于驾驶室内以略掉起升钢丝绳复杂的缠绕方式。

The results indicate that in the synchronizing condition the MRF is unyielded, every point of MRF in the flow field has the same angular velocity. Under the slipping condition, with the increase of magnetic field or the decrease of slip speed, MRF may transfer from whole yield to partial yield. When the MRF wholly yields, the angular velocity of MRF increases nonlinearly with its radius, the non-linear distribution becomes more obvious as the magnetic intensity in the working gap increases. When the MRF partially yields, the yield region expands with the decrease of magnetic intensity or the increase of slip speed and the unyield region always reaches the driven rotor. The transfer torque of MRTD increases with the increase of the external magnetic field, but the transfer torque maintains a constant value approximately with the variation of slip speed at the same magnetic intensity.

研究结果表明，在同步工况下，传动装置流场中磁流变液未屈服，各点角速度相同；在滑差工况下，随外加磁场的增大和滑差转速的减小，磁流变液逐渐从完全屈服向部分屈服转变；磁流变液完全屈服时，磁流变液角速度随半径呈非线性增加，工作间隙中磁场越强，流场的非线性分布越明显；磁流变液部分屈服时屈服区域随外加磁场的增大而减小，随滑差转速的增大而增大，未屈服区与主动转子相连；稳态下磁流变传动装置传递的转矩随外加磁场的增加而近似呈线性增大，但在相同外加磁场下，传递转矩基本不随滑差转速改变而改变，表现出良好的恒转矩特性。

The objective is to subjugate and discourage the people, because that allows the elite to continue to rule unopposed.

其目的是压制和打击人民的积极性，因为这可以让实权派继续统治不会沦为反对派。

GOD,this is the second time you vanquished me!
