对圆振动筛和直线振动筛的轴承受力进行了较详细的分析，并提出了在一个回转周期内轴承受力平均值的近似计算公式，经过分析和计算得出了有益的结论，对振动筛正确设计和轴承选型提供了理论依据。
The mechanical behaviors of the circular vibrating screen and the linear vibrating screen are analyzed in detail, and the approximate formula of the average value of the bearing force in one rotation cycle is proposed. The beneficial conclusions are obtained through analysis and calculation. The correct design of the sieve and bearing selection provide the theoretical basis.
