    裝載機曲軸箱出現異響是什么原因?

    內容詳情:
    裝載機作為生活和工作中常見的工程機械之一,大大提高了工作效率,但是經過長時間的使用或者保養的不注意,裝載機還是會出現一些問題的,比如裝載機曲軸箱出現異響。
    As one of the common construction machinery in life and work, the loader has greatly improved the work efficiency, but after a long time of use or careless maintenance, the loader will still have some problems, such as abnormal noise in the crankcase of the loader.
    裝載機高速運轉時,如果出現“咯噔、咯噔”悶擊聲,減小油門時尤為明顯,這是主軸瓦軸向間隙過大所致;沿汽缸上下各處均有類似小鐵錘輕擊鐵塊的聲音,排氣管冒藍煙(伴有燒機油現象),用長柄螺絲刀抵在汽缸體處更容易聽到,即可斷定是活塞環側隙過大或環折斷所致。
    When the loader is running at high speed, if there is a "click, click" dull sound, it is particularly obvious when reducing the throttle, which is caused by the excessive 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 emits blue smoke (accompanied by oil burning). It is easier to hear when touching the cylinder block with a long handle screwdriver. It can be concluded that it is caused by excessive 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,且打開加機油口蓋時發現有氣泡(說明有漏氣現象),這是活塞與缸套配合間隙過大所致;若在同一部位略靠曲軸方向聽到“嘎、嘎、嘎”撞擊聲,則是連桿扭曲致使其在工作中搖擺產生的敲擊聲,后兩種聲響在改變柴油機轉速時更明顯,且較易于區別。
    A dull knocking sound of "empty thump, empty thump" is heard at the full length of the loader cylinder, and bubbles are found when opening the oil filler cover (indicating air leakage), which is caused by the excessive matching clearance between the piston and the cylinder liner; If the impact sound of "GA, GA, GA" is heard in the same part slightly close to the crankshaft, it is the knocking sound caused by the swing of the connecting rod due to the distortion of the connecting rod. The latter two sounds are more obvious when changing the speed of the diesel engine and are easier to distinguish.
    當裝載機突然改變負荷時,在曲軸箱附近可清晰地聽到短促的鈍啞的敲擊聲,并隨負荷或轉速的增加而急劇變化,響聲大,無負荷時則不明顯。這是連桿瓦過度磨損而造成連桿瓦與連桿軸頸配合間隙過大所致;若使柴油機某缸斷油,如果此異響立即消失,則說明是該缸的連桿瓦響。
    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 is loud, 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, if the abnormal noise disappears immediately, it means that the connecting rod bush of the cylinder makes a noise.
