常见混凝土搅拌车减速机故障介绍
混凝土搅拌车的减速机是整个上装部分“压力”的部分了，毕竟整个上装罐体部分包括装载的混凝土转动都离不开它。
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.
那么减速机在长时间的工作使用后，难免会出现一些小的故障问题。基本上更常见的分为漏油和出现异响两类问题。
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.
是漏油的问题，我们要根据不同的漏油位置，来处理问题:1、油封处漏油，这种情况更容易造成的就是异物划伤或缠绕所致，排除异物并更换油封；2、端盖和壳体处漏油，这个地方漏油多是端盖紧固螺丝松动造成，检查并上紧螺丝一般就可；3、与液压马达连接处漏油，此时应检查连接处O型圈是否完好，同时检查固定螺丝是否松动。搅拌车减速机
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
减速机异响我们要检查齿轮油是否正常，齿轮油缺少或杂质过多，应及时更换齿轮油；重车的时候才出现异响，检查罐体拖轮和跑带是否磨损严重，如果出现磨损严重，就会造成载重的时候罐体角度过大使减速机出现异响；出现异响并且车身抖动，多是由液压系统问题造成，检查液压油是否出现问题，如未发现异常就需要检查油泵和液压马达。混凝土搅拌车
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
当然出现严重的就是减速机出现“卡死”，如果检查液压系统没有问题可以正常工作的话，我们就需要人员来拆开减速机修理了。
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.
