常見混凝土攪拌車減速機故障介紹
混凝土攪拌車的減速機是整個上裝部分“壓力”的部分了，畢竟整個上裝罐體部分包括裝載的混凝土轉(zhuǎn)動都離不開它。
The reducer of concrete mixer truck is the "pressure" part of the whole loading part. After all, the rotation of the whole loading tank body, including the loaded concrete, is inseparable from it.
那么減速機在長時間的工作使用后，難免會出現(xiàn)一些小的故障問題。基本上更常見的分為漏油和出現(xiàn)異響兩類問題。
Then, after the reducer is used for a long time, some small faults will inevitably appear. Basically, the most common problems are oil leakage and abnormal noise.
是漏油的問題，我們要根據(jù)不同的漏油位置，來處理問題:1、油封處漏油，這種情況更容易造成的就是異物劃傷或纏繞所致，排除異物并更換油封；2、端蓋和殼體處漏油，這個地方漏油多是端蓋緊固螺絲松動造成，檢查并上緊螺絲一般就可；3、與液壓馬達連接處漏油，此時應(yīng)檢查連接處O型圈是否完好，同時檢查固定螺絲是否松動。攪拌車減速機
The first choice is oil leakage. We should deal with the problem according to different oil leakage positions: 1. Oil leakage at the oil seal. The most likely cause of this situation is the scratch or winding of foreign matters. Remove foreign matters and replace the oil seal; 2. The oil leakage at the end cover and shell is mostly caused by the loose fastening screws of the end cover. Generally, it can be solved by checking and tightening the screws; 3. There is oil leakage at the connection with the hydraulic motor. At this time, check whether the O-ring at the connection is intact and whether the fixing screw is loose. Mixer reducer
減速機異響我們要檢查齒輪油是否正常，齒輪油缺少或雜質(zhì)過多，應(yīng)及時更換齒輪油；重車的時候才出現(xiàn)異響，檢查罐體拖輪和跑帶是否磨損嚴(yán)重，如果出現(xiàn)磨損嚴(yán)重，就會造成載重的時候罐體角度過大使減速機出現(xiàn)異響；出現(xiàn)異響并且車身抖動，多是由液壓系統(tǒng)問題造成，檢查液壓油是否出現(xiàn)問題，如未發(fā)現(xiàn)異常就需要檢查油泵和液壓馬達。混凝土攪拌車
If the reducer makes abnormal noise, we should first check whether the gear oil is normal. If the gear oil is missing or there are too many impurities, we should replace the gear oil in time; The abnormal noise only occurs when the vehicle is loaded. Check whether the tank tug and running belt are seriously worn. If the wear is serious, the angle of the tank will be too large when the load is loaded, which will cause the abnormal noise of the reducer; Abnormal noise and body shaking are mostly caused by hydraulic system problems. Check whether there is a problem with the hydraulic oil. If no abnormality is found, check the oil pump and hydraulic motor. Concrete mixer
當(dāng)然出現(xiàn)嚴(yán)重的就是減速機出現(xiàn)“卡死”，如果檢查液壓系統(tǒng)沒有問題可以正常工作的話，我們就需要人員來拆開減速機修理了。
Of course, the serious problem is that the reducer is "stuck". If there is no problem with the hydraulic system and can work normally, we need professionals to disassemble the reducer for repair.
