我厂使用的C20型摩擦焊机主轴前旋转夹具轴承寿命鞍短,尤其是设备长期处于满负荷运转时就更为严重。针对这个问题,我厂对该设备的轴承结构作了改进。经过实际运转考核表明,其寿命提高了8～10倍,取得了较满意的效果。一、原结构轴承失效原因分析 C20型摩擦焊机的最大顶锻力为200kN,主轴转速为2000r/min,每一工作周期约为10～20s。在这样的条件下工作,普通国产滚动轴承的寿命只有100
My factory uses the C20-type friction welding machine spindle rotating fixture bearing saddle short life, especially when the equipment is in full operation for a long time even more serious. In response to this problem, I plant the bearing structure of the device made an improvement. After the actual operation examination showed that the life expectancy increased by 8 to 10 times, and achieved more satisfactory results. First, the original structure of the bearing failure analysis C20-type friction welding machine maximum forging force of 200kN, spindle speed of 2000r / min, each working cycle is about 10 ~ 20s. Work in such conditions, ordinary domestic rolling bearing life of only 100
