[0002] The elevator counterweight wheel generally includes a wheel with a mounting hole at the center, two bearings placed in the mounting holes, and a long shaft passing through the two bearings. A separation ring is provided at the middle of the long shaft with two sides corresponding to the two bearings, and the wheel, bearing and long shaft are positioned by the separation ring. In most cases, the middle of the long shaft is interference fit with the inner ring of the bearing, and the outer ring of the bearing is interference fit with the mounting hole of the wheel, so that the elevator counterweight wheel can be assembled, and the wheel can rotate relative to the long shaft. However, since the inner ring and the outer ring of the bearing are respectively interference fit with the middle of the long shaft and the mounting hole of the wheel, it is necessary to use a press-fit method to press the middle of the long shaft into the bearing and the bearing into the mounting hole of the wheel. The prior art generally uses a method of first pressing a bearing into the mounting hole of the wheel, then pressing the long shaft, and finally pressing another bearing.
