我们过去铸铝转子是铸完以后自然冷却到常温,用大锤将临时轴打出。由于配合间隙小,再加上曾加温到700℃,所以脱轴是相当困难的。有时一个转子就要打几十大锤累的满头大汗,体力劳动强度很大。如果稍不小心就可能将风叶或端环打坏。这种脱轴方法使铸铝轴很快被磨损,每年都有很多铸铝轴报废,对工具车间压力很大。这些情况引起车间党支部的重视,发动群众献计献策, We used to cast cast aluminum rotor is naturally cooled to room temperature after casting, using a sledgehammer to hit the temporary axis. With the small gap, coupled with heated to 700 ℃, so off-axis is quite difficult. Sometimes a rotor will hit dozens of hammer tired tired sweat, physical strength is great. If you accidentally may damage the blade or end ring. This method of off-axis cast aluminum shaft wear quickly, every year a lot of cast aluminum shaft scrap, the pressure on the tool shop. These situations arouse the attention of the party branch of the workshop, mobilize the masses to make suggestions,
