It comprises an in-put shaft hinged to its yoke through one axis, and an out-put shaft also hinged to its yoke through another axis, and these two yokes (13) were combined together by only one axis position, perpendicular to that two yoke axes like a cross, so that this combined axis will bend just like the angle bisector of that two shafts to maintain its constant velocity by a few methods, firstly, by using a section of gear teeth mesh at both ends of the shafts' teeth were so polished so that it can turn longitudinally as usual gear, and also sideways, to provide a larger solid angle of turning from ordinary 45 degrees into 60 or even more.

它包括输入轴，其通过一根轴铰链连接于叉形支架，和输出轴，其通过另一根轴也铰链连接于其叉形支架。并且这两个叉形支架(13)只需用一根相对垂直铰链轴相连而组合在一起，使得这种组合的轴总能形成这两个轴的角平分线，以通过少数几种方法保持其恒速，首先，通过用啮合在轴的两端的一段齿轮齿抛光为以能够像普通齿轮一样纵向转动，并且还能够侧向转动，以提供较大的转向立体角，从通常的45度变成60度或更大。

For achieve two-wheel balanced function, we used fuzzy control algorithm to program the controlled codes.

The place of the innovation of this plan depends on becoming ball gear and dish when form emery wheel undertakes clench the teeth moves, ball gear is not to bypass the upend axis of ball heart turns, circle parallel to turn at crossing the axis of the upend axis of ball heart however, dish the motion of form emery wheel is the translation inside 2 dimension plane.

该方案的创新之处在于当球齿轮和盘形砂轮进行啮合运动时，球齿轮并不是绕过球心的竖直轴转动，而是绕平行于过球心的竖直轴的轴转动，盘形砂轮的运动是在二维平面内的平动。

Through the characteristic parameters, the system's real-time moment of inertia is given. Then golden section adaptive control law and logic derivative control law both based on moment of inertia are designed. The two kind of control laws are combined to control the attitude of spacecraft and their simulation results are compared with the ones of PD control law which is designed based on the certainly-known system model. The results show that this adaptive control law is effective on the kind of time-variable system studied in this paper.

As the rotating magnetic field into which both the rotor cutting electricity conductor when a magnetic line of force, to achieve a rotating magnetic field from the force rotation for the corresponding rotor rotation, the rotor can achieve rotor lead screw for the corresponding movement.

由于旋转磁场对放入其中的通电导体既转子切割磁力线时具有力的作用，从实现了旋转磁场的转动迫使转子作相应的转动，所以转子才可以实现转子带动丝杠作相应的运动。
