当齿轮泵体腔研伤严重时,镗削后使腔体尺寸增加模数超过0.3个时,齿轮在工作时会发生干涉。若采用加大中心距办法来解决,则体腔尺寸也增大,会改变泵体的原有参数,带来许多不便。而采用粘接方法,可按原设计尺寸修复,还可将泵腔内孔减小,使用旧齿轮时也不必改变中心距,这对修复国外进口设备的特殊型齿轮泵有重要意义。我们用无胶粘接铁套的方法很好。若齿轮齿面较好,齿顶磨损,需将齿
When the gear pump body cavity serious injury, after boring to increase the size of the cavity module more than 0.3, the gear will interfere in the work. If the way to increase the center distance to solve, then the body cavity size also increases, will change the original parameters of the pump body, bringing a lot of inconvenience. The use of bonding methods, the original design size can be repaired, but also reduce the pump cavity hole, the use of the old gear do not have to change the center distance, which repairs the imported special equipment gear pump is of great significance. We use glueless iron sleeve method is very good. If the gear tooth surface is good, tooth top wear, need to be tooth
