一种减速器轴承座的修复方法
摘要：
一种减速器轴承座的修复方法，它包括如下步骤：(1)对减速器设备进行解体拆卸，清洗轴承座，检测尺寸，确定损伤部位及磨损量，去除疲劳层；(2)在轴承座基材表面预涂与白乳胶混合的纯碳粉，并采用等离子弧熔覆；(3)采用等离子弧熔覆对有碳粉层的轴承座内孔表面预涂配制好的合金粉末，所述合金粉末成分质量百分比为：C 0.3％～0.5％、Cr 14％～16％、Fe 16％～18％、P 2％～2.8％、Si 2.5％～3％、W 1％～3％、余量为Ni；(4)对熔覆后的轴承座进行机械加工和探伤，获得尺寸、公差均满足要求的轴承座，完成减速器设备组装。本发明工艺简单，可控性强，能源消耗少，明显提高了轴承座的工作寿命和可靠性。
摘要（英）：

A speed reducer bearing block repair method includes the steps: (1) disassembling a speed reducer, cleaning a bearing block, detecting the size of the bearing block, determining a damaged portion and abrasion loss and removing a fatigue layer; (2) pre-coating the surface of a substrate of the bearing block with pure carbon powder mixed with white emulsion, and performing plasma arc cladding; (3) pre-coating the surface of an inner hole of the bearing block having a carbon powder layer with prepared alloy powder by plasma arc cladding; (4) performing machining and flaw detection for the clad bearing block to obtain the bearing block with the size and tolerance meeting requirements and assemble the speed reducer. The alloy powder comprises, in weight percent, 0.3%-0.5% of C, 14%-16% of Cr, 16%-18% of Fe, 2%-2.8% of P, 2.5%-3% of Si, 1%-3% of W and the balance Ni. The repair method is simple in process, high in controllability and less in energy consumption, the service life of the bearing block is obviously prolonged, and reliability of the bearing block is obviously improved.
