滑动轴承

产品介绍

滑动轴承是用于混炼机齿轮泵上的关键部件,又称轴瓦。该部件是制约生产线长周期运行的关键因素。由于进口备件采购周期长,价格昂贵,滑动轴承国产化可以大大压缩采购周期,降低采购成本及维护成本,具有显著的经济效益和社会效益。

 

结构组成

滑动轴承为二体组合结构,由轴承外套与轴承内套组成,两者热装后,在连接处加防转销,使两者互锁。其中轴承外套材质是优质合金结构,经锻造、调质、淬火及稳定化处理,具有较高的综合机械性能。轴承内套材质是优质碳素钢和厚度1mm的银层组成,银层纯度达99.9%,采用离子喷涂工艺。

关键过程

银涂层喷涂是关键工艺。银涂层是通过等离子喷涂设备将银粉末快速加热至熔融或半熔融状态,并借助气流雾化快速沉积在钢套内表面,从而形成与钢基体紧密结合的涂层。涂层制作的工艺流程如下:

通过此制作工艺得到的银涂层的结合强度经拉伸试验机,根据“热喷涂涂层结构强度试验法”(HB5476-91)进行检测,检查结果如下:
