泥浆泵使用久了,主轴和纣轴的轴承孔就会旷动。过去采用顶丝加固的办法,但又产生中心距变动和轴承被顶变形的现象。现在我们采取扩孔加套的办法,为扩孔做出一种落地镗孔工具,经过试验,完全达到质量要求。落地镗孔工具的结构如图。其使用方法如下:在泵体孔16、17两边加盖3、4进行导正,穿入刀杆体1(机件4、5、6、7、8、9与1整体安装),装上皮带轮2和滑键15,按装刀头13和14并用顶丝11和12顶固。通过动
Mud pump used for a long time, the spindle and shaft shaft bearing hole will Kuang. In the past, the method of using jacking wire reinforcement was adopted, but there was a phenomenon that the center distance was changed and the bearing was deformed top. Now we take reaming and nesting methods to make a counterbore bore boring tools, after testing, fully meet the quality requirements. Floor boring tool structure as shown. The use of the method is as follows: both sides of the pump body holes 16, 17 are covered with a cover 3, 4, into the holder body 1 (parts 4,5,6,7,8,9 and 1 overall installation), fitted with a pulley 2 and the sliding key 15, according to the installation of the first 13 and 14 and with top wire 11 and 12 top fixed.
