目前建材行业电机、风机、磨机减速机等采用皮带传动的设备中，常见的皮带轮安装结构多数由圆柱孔加平键组成，此种结构虽然加工方便，但由于配合较紧 ,加之带轮长时间工作，轴孔配合表面易产生锈蚀等，拆换较困难，需用拨轮器或锤击拆卸，易损坏带轮，严重时使轴弯曲变形等。
At present, the building materials industry, motor, fan, mill reducer and other belt drive equipment, the common structure of the pulley installation by the majority of cylindrical hole with flat key composition, although the processing is convenient, but due to tighter, coupled with the pulley for a long time Work, shaft hole with the surface prone to corrosion, etc., more difficult to dismantle, need to use dials or hammer disassembly, easy to damage the pulley, so serious when the shaft bending deformation.
