陀螺理论对复杂旋转机构运动的再分析

Using Gyroscopic Theory to Further Analyze the Motion of Complex Rotary Mechanism

用陀螺理论中刚体一般运动的方程对汽车、工程机械、振动磨机等系统中传动系的双万向节进行了运动分析。并进一步证明双万向节匀速传动的两个条件不仅适用于双万向节的三个轴在同一平面的运动状况，而且是当三个轴不在同一平面时匀速传动的主要条件。

The general motion equation of rigid body in gyroscopic theory is used to analyze the motion of double universal joint in the transmission system of engineering mechanism vibration grinder. The two-conditions of double universal joint's uniform rotation fitthe state of rotation that whether the three shafts of double universal joint are in the sameplane or not in the same plane.
