The adjustment component is placed on a base plate 101 and fitted with a simple cavity 105. By pressing down the rack shaft 203, the gear set tightens the cavity 105, aligning the axis of the cavity 105 with the axis of the base plate 101. A solution, such as polyurethane, is poured around the cavity 105 to fix it in place. The polyurethane wheel can be cast by installing the positioning core 103, wheel core 102, and mold cover 104. Polyurethane wheels within a certain diameter range can share the adjustment component and the combined mold. Compared to existing technologies, only a simple cavity 105 needs to be manufactured separately, resulting in a very short mold-making cycle and low mold cost.
