反向

When two axes make the synchronized reverse rotation, on each instantaneous two axis eccentric qualities produce the centrifugal force of inertia, always mutually counterbalances along x-x force component, but always mutually superimposes along Y-Y force component, this has formed the sole this direction simple harmonics strength.

两轴作同步反向回转时，每一瞬时两轴上偏心质量所产生的离心惯性力，沿x-x方向的分力总是互相抵消，而沿Y-Y方向的分力总是相互叠加，这就形成了单一的该方向的简谐力。该力作用在筛箱上，驱动筛箱作轨迹为直线的往复振动。
