摘要 给出了特大型负游隙四点接触球轴承接触点处应力分布的分析方法,并计算了某型号转盘轴承在空载时不同负游隙下球与内外圈之间的接触应力和接触区面积。结果表明:空载时,负游隙轴承发生四点接触,四点处接触面积近似相等,接触应力分布近似一样,内圈受到的接触应力略大于外圈。负游隙绝对值越大,接触区面积越大,接触应力也越大。可以通过增大负游隙绝对值来提高轴承摩擦力矩。 The analysis method of contact stresses between balls and inner/outer ring raceway of large-sized four-contact-point ball bearing with negative axial play is present. The contact stresses and contact areas between balls and inner/outer ring raceway of a slewing ring bearing are computed at different negative axial plays without applied load. The results show that a ball contacts with inner/outer ring raceway at four points whose contact areas and contact stress distribution are approximately same. The contact stresses between balls and inner ring raceway are slightly higher than those at outer ring raceway. Contact stress and contact area increase with absolute value of negative axial play increasing. Startup friction torque can be improved by increasing the absolute value of negative axial play.
