摘要
介绍了NJG型满装圆柱滚子轴承与滚子装配有关的主要结构参数尺寸及公差的计算方法,并推导了外圈滚道直径公差的计算方法。经验证,轴承合套率达到90%以上,装配后的轴承旋转灵活,满足了工程应用需求。
The calculation method is introduced for dimension and tolerance of main structural parameters relating to assembly of rollers of NJG type full complement cylindrical roller bearings,and the calculation method is derived for diameter tolerance of outer ring raceway. The matching rate of the bearings reaches over 90% after verification. The bearings rotate flexibly after assembly,and the application requirements of engineering are met.
