Failure of oil leakage and abnormal sound of reducer of concrete mixer

混凝土搅拌机也称水泥罐机，减速机是混凝土搅拌机上的重要配件，减速机在搅拌车上起到什么作用呢？知道混凝土搅拌机的工作原理就明白减速机的作用了，搅拌车工作原理是通过取力器装置将专用车底 盘的动力取出，并驱动液压系统的变量泵，把机械能转化为液压能传给定量马达，马达再驱动减速机，由减速机驱动搅拌装置，对混凝土进行搅拌。 减速机也会出故障，很多人碰到减速机出故障不知道该怎么办？下面我们就来了解一下减速机的常见故障有哪些？

Concrete mixer also known as cement tank machine, reducer is an important part of the concrete mixer, what role does the reducer play in the mixer truck? Knowing the working principle of the concrete mixer, we can understand the function of the reducer. The working principle of the mixer truck is to take out the power from the chassis of the special vehicle through the power take-off device, and drive the variable pump of the hydraulic system. The mechanical energy is converted into hydraulic energy and transmitted to the quantitative motor. The motor drives the reducer, and the reducer drives the mixing device to mix the concrete. The reducer will also break down. Many people don't know what to do when the reducer fails? Now we will learn about the common faults of the reducer?

1、漏油： 轴封漏油，轴封漏油多是由于使用不当造成减速机划伤或减速机输出轴划伤及异物缠绕所致。此时需要更换轴封或者是更换油封，在减速机的使用过程中要及时清理油封 处异物。端盖与壳体连接处漏油，这种形式的漏油多是由于减速机连接螺栓松动造成的，此时需要及时的复紧端盖和壳体连接螺栓或者更换减速机，或者是更换减速机端 盖和壳体间的O型圈。为避免此类情况再发生，平时要定期的检查螺栓扭力。 马达和减速机连接处漏油，这主要是因为马达和减速机在安装的时候对O型圈的密封不达标。此时需要更换马达和减速机连接处的O型圈，检查马达和减速机安装表面是否 有划伤。在搅拌车的平时使用过程中注意检查马达和减速机安装的螺栓是否有松动。

1. Oil leakage: the shaft seal leaks oil, which is mostly caused by improper use of the reducer or the output shaft of the reducer and foreign matter winding. At this time, it is necessary to replace the shaft seal or replace the oil seal. During the use of the reducer, the foreign matters at the oil seal should be cleaned in time. There is oil leakage at the connection between the end cover and the housing. This kind of oil leakage is mostly caused by the loosening of the connecting bolts of the reducer. At this time, it is necessary to tighten the connecting bolts of the end cover and the shell, or replace the reducer, or replace the O-ring between the end cover and the shell of the reducer. In order to avoid this kind of situation from happening again, the bolt torque should be checked regularly. The motor and reducer joint oil leakage, this is mainly because the motor and reducer in the installation of the O-ring seal is not up to standard. At this time, it is necessary to replace the O-ring at the connection between the motor and the reducer, and check whether the mounting surface of the motor and the reducer is scratched. Pay attention to check whether the bolts installed on the motor and reducer are loose during the normal use of the mixer.

2、异响 在水泥搅拌车的使用过程中减速机如果出现异响，要做一下检查：查看减速机内是否有齿轮油；在油位观察窗处检查油位是否正常；放出少量油液看是否有发黑变质并校对保 养时间；检查减速机是否受到过外力的冲击。如果放油发现有大量铁屑，那就是减速机内部已经损坏，须更换减速机，平时要定期的对减速机做保养。

2. Abnormal noise in the use of cement mixer, if the reducer makes abnormal noise, check: check whether there is gear oil in the reducer; check whether the oil level is normal at the oil level observation window; drain a small amount of oil to see if there is blackening and deterioration and check the maintenance time; check whether the reducer has been impacted by external force. If a large number of iron filings are found in the oil discharge, it is the internal damage of the reducer, and the reducer must be replaced, and the reducer should be maintained regularly.
