According to the turntable bearing for the super-tonnage crawler crane, a six-row cylindrical roller combined structure of an existing turntable bearing for the super-tonnage crawler crane is improved, the inner side and the outer side of the middle ring are each provided with a row of radial rollers, the radial load capacity of the bearing is improved, meanwhile, the lower three rows of axial rollers are designed into two rows, and the radial load capacity of the bearing is improved. The axial rollers in each row are divided into two columns, namely, the working length of the axial rollers in the lower single row is lengthened, and the axial loading capacity of the bearing is also effectively guaranteed, so that the stability of product operation is obviously improved, and the application range is wider; the invention further provides a method for controlling the planeness of the different surfaces of the inner ring and the outer ring of the turntable bearing for the super-tonnage crawler crane, and the planeness of a plane formed by the base plane of the outer ring and the base plane of the inner ring is controlled by controlling the form and location tolerance of each ferrule, the assembly clearance, the relative height difference of all parts of the two ferrules and the like. Therefore, the technical requirement of bearing inner and outer ring different-surface planeness is met, and the production efficiency is improved.

    本发明提供一种超大吨位履带吊用转盘轴承,通过改进现有超大吨位履带吊用转盘轴承的六排圆柱滚子组合式结构,在中圈的内外两侧分别设置一排径向滚子,提高了轴承的径向负载能力,同时将下面的三排轴向滚子设计为两排,每一排轴向滚子分为两列,相当于加长了下面单排轴向滚子的工作长度,轴承的轴向负载能力也得到了有效保证,因此,产品运行的稳定性有了显著提高,适用范围更广;本发明还提供了上述超大吨位履带吊用转盘轴承内外圈异面平面度的控制方法,通过控制各套圈的形位公差、组配游隙及两套圈各个部位的相对高度差等方法控制外圈基面与内圈基面构成平面的平面度,从而保证轴承内外圈异面平面度的技术要求,提高生产效率。
