摘　　要：机器飞轮转动时,轴承可能受到一定的附加压力。文章通过均质圆盘转动实例,根据质心运动定理和对固定点的角动量定理,给出一种较为简单的计算这种压力的方法,在此基础上指出了改变这种压力的方法。While the flyweel of a machine is working,the bearing may be subjected to a certain additional pressure. This paper,with the practical example of a rotating disc whose mass distribution is homogeneous,according to the law of mass - center motion and the law of angular momentum to a static point, gives an easier way to calculate the pressure. Based on this,a way is also pointed out to change the pressure in question.

关 键 词：定轴转动 附加压力 力矩 角动量
