is fixed to a securing table of the rolling bearing device for the wheel. Then, by rotating a spindle incorporated in one end of the inner ring at an upper side in the vertical direction, a flange surface of a flange part which is formed at one end of the inner ring at an upper side in the vertical direction is rotated to bring this flange surface which is rotating into contact with a rotary grinding wheel, whereby the flange surface of the inner ring is ground.
However, in the above described conventional method of producing the rolling bearing device for the wheel, there is a problem that it is difficult to vary a position of the rotary grinding wheel according to a grinding position of the flange surface,objective comprehensive weighting methods, the basic elements were finally integrated, and an accurate spatial distribution pattern of the RECC in China's Fengxian County was obtained. In addition, based on the construction of a three-dimensional spatial conceptual model, this study was able to finally obtain four specific types of functional partitions in the study areas, and proposed specific development proposals according to the different types of functional zoning from a systemic perspective. It was observed that the RECC had been decreasing from a central built-up area to the surrounding townships, and the spatial distribution patterns were distinctly scattered. In addition, the townships with smaller land scales had more obvious advantages in the RECC. However, fluctuating upward trends were observed after the lowest thresholds had been reached as for the
