过去我們对磨損的軸承座一般是采用压套的方法来修复的。修理时先把旧軸承座的內孔扩大6～12公厘(但一定要在机器强度允許的条件下),然后鏜一个同样材料的样圈,装到这內孔里去。这种方法虽然可以使磨損的軸承座和軸承結合紧密,但比較費工、費料,是很不經济的。后来我們采用加热方法修复軸承座,效果很好。現在把这种方法介紹如下,供大家参考。 1.加热設备——是用气焊設备,噴咀最好用最大号的。 2.加热温度——鑄鉄材料要在800℃左右,鋼材料要在750℃左右。加
In the past we wear the bearing housing is generally used to repair the method of compression. Repair the first hole in the old bearing seat to expand 6 to 12 mm (but must be allowed under the conditions of the machine strength), and then boring a sample of the same material, loaded into this hole. Although this method can wear bearings and bearing wear together, but more laborious, costly, it is uneconomical. Later, we use the heating method to repair the bearing seat, the effect is very good. Now introduce this method as follows, for your reference. 1. Heating equipment - is the use of gas welding equipment, the best nozzle with the largest number. 2. Heating temperature - Casting material to about 800 ℃, steel material to about 750 ℃. plus
