拖拉机上的一些齿轮因经常换档或进入啮合,造成磨损和碰伤损坏。对于这些齿轮,可采用换位法进行修理。 1.反转换位法结构对称的齿轮单边损坏时,可用反转换位法修理。例如,东方红-75/54拖拉机变速箱第二轴上的Ⅱ、Ⅴ档齿轮,当齿圈单面磨损后,可将铆钉铲掉,压出齿圈,反转180°对正铆钉孔重新压入,并用铆钉铆牢固。压装齿圈时,一般先将齿圈在机油或水中加热到100℃,然后迅速压 Some of the tractor gear due to frequent shift or into engagement, causing wear and bruising damage. For these gears, you can use the transposition method to repair. 1. Anti-conversion bit structure Symmetrical gear unilateral damage, the reverse conversion method can be used to repair. For example, the Dongfanghong -75 / 54 tractor gearbox on the second axis of gear Ⅱ, Ⅴ, when the ring gear worn on one side, the rivet shovel out, out of the ring gear, inverted 180 ° alignment rivet hole re- Press in and rivet firmly with rivets. When the gear ring is pressed, the ring gear should first be heated to 100 ° C in oil or water and then quickly pressed
