裝載機作為生活和工作中非常常見的工程機械之一，其工作效率得以提高，但是使用時間長了或保養(yǎng)不到位的話，裝載機還是會出現(xiàn)一些問題的，比如裝載機的曲軸箱出現(xiàn)異響。

As one of the very common construction machinery in life and work, the working efficiency of the loader can be improved, but if it is used for a long time or the maintenance is not in place, the loader will still have some problems, such as abnormal noise in the crankcase of the loader.

裝載機在進行高速運轉(zhuǎn)的時候，會出現(xiàn)“咯噔、咯噔”悶擊聲，當(dāng)在減小油門的時候更為明顯，這是主軸瓦軸向間隙太大所導(dǎo)致的；沿汽缸上下各處均有類似小鐵錘輕擊鐵塊的聲音，排氣管會冒藍煙（可能還會伴有燒機油的現(xiàn)象），用長柄螺絲刀抵在汽缸體處聽起來更加明顯，即可斷定是活塞環(huán)側(cè)隙太大或環(huán)折斷所導(dǎo)致的。

When the loader is running at high speed, there will be a "click, click" dull sound, which is more obvious when reducing the throttle, which is caused by the too large axial clearance of the main shaft pad; There is a sound similar to the sound of a small hammer tapping an iron block up and down the cylinder, and the exhaust pipe will emit blue smoke (possibly accompanied by the phenomenon of burning oil). It sounds more obvious to use a long handle screwdriver against the cylinder block. It can be concluded that it is caused by too large side clearance of the piston ring or broken ring.

在裝載機汽缸全長部位聽到沉悶的“空咚、空咚”敲擊聲，打開加機油口蓋的時候，發(fā)現(xiàn)有氣泡（說明存在漏氣現(xiàn)象），這是活塞與缸套配合間隙太大所導(dǎo)致的；如果在同一部位略靠曲軸方向聽到“嘎、嘎、嘎”撞擊聲，則是連桿扭曲導(dǎo)致其在工作中搖擺產(chǎn)生敲擊聲，后兩種聲響在改變柴油機的轉(zhuǎn)速時更加明顯，而且更方便區(qū)別。

A dull knocking sound of "empty thump, empty thump" was heard at the full length of the loader cylinder. When opening the oil filler cover, bubbles were found (indicating air leakage), which was caused by the large matching gap between the piston and the cylinder liner; If the impact sound of "GA, GA, GA" is heard in the same part slightly in the direction of the crankshaft, it is the distortion of the connecting rod that causes it to swing and produce knocking sound during operation. The latter two sounds are more obvious when changing the speed of the diesel engine, and it is more convenient to distinguish.

在裝載機突然改變負荷的時候，在曲軸箱的附近可以清晰地聽到短促的鈍啞敲擊聲，并隨著負荷或轉(zhuǎn)速增加而發(fā)生急劇變化，響聲不斷加大，無負荷的時候則不明顯。這是連桿瓦過度磨損而導(dǎo)致連桿瓦與連桿軸頸配合間隙過大所導(dǎo)致的；如果使柴油機某缸斷油，此異響則會立即消失，這說明是該缸連桿出現(xiàn)瓦響。

When the loader suddenly changes the load, the short dull knocking sound can be clearly heard near the crankcase, and changes sharply with the increase of load or speed. The sound increases continuously, but it is not obvious when there is no load. This is caused by excessive wear of connecting rod bush, resulting in excessive fit clearance between connecting rod bush and connecting rod journal; If the oil of a cylinder of the diesel engine is cut off, the abnormal sound will disappear immediately, which indicates that the connecting rod of the cylinder has tile sound.
