摘　　要：针对面对面安装的圆锥滚子轴承进行受力分析,分别计算轴承预紧力、预紧前后的轴承载荷。通过分析,有效地解决了轴承预紧力的计算问题,为后续进行轴承寿命计算提供理论依据,可有效提高螺杆压缩机的可靠性。同时,根据载荷分布特点,对圆锥滚子轴承的选型给出合理化建议。In this paper, the load of tapered roller bearings when they are installed face to face is analyzed and calculated, and the preload and the load distribution before and after preloaded the bearing is calculated individually. Through the analysis, it has effectively solved the problem of calculating the bearing preload, which provides a theoretical basis for the subsequent calculation of bearing life, and can effectively improve the reliability of screw compressor. At the same time, according to the characteristic of load distribution, the reasonable suggestions to the selection of tapered roller bearing are given.
