摘要： A bearing structure includes a main body internally defining a shaft space; the shaft space axially extends a full length of the main body and communicates with at least one extension space; and the extension space is radially outward extended from the shaft space and also axially extends a full length of the main body. The shaft space has a non-circular cross section. In a cooling fan using the bearing structure, a rotor shaft is inserted in the shaft space. With the shaft space having a non-circular cross section, it is possible to largely increase the support pressure of a lubricant filled between the rotor shaft and the shaft space and accordingly, reduce the frictional contact between the rotor shaft and the shaft space as well as the noise and vibration produced during the operation of the cooling fan.
摘要翻译：轴承结构包括内部限定轴空间的主体; 所述轴空间轴向地延伸所述主体的全长并与至少一个延伸空间连通; 并且延伸空间从轴空间径向向外延伸并且还轴向延伸主体的全长。轴空间具有非圆形横截面。在使用轴承结构的冷却风扇中，转子轴插入轴空间。在轴空间具有非圆形横截面的情况下，可以大大增加填充在转子轴和轴空间之间的润滑剂的支撑压力，因此也可以减小转子轴和轴空间之间的摩擦接触作为在冷却风扇运行期间产生的噪音和振动。
