The concrete mixer is also called the cement tank truck. The reducer is an important part of the concrete mixer truck. What is the function of the reducer of Zhongke Jufeng concrete mixer truck in the mixer truck? Know the working principle of the concrete mixer truck and understand the function of the reducer. The working principle of the mixer is to remove the force of the special truck tray through the electric equipment and drive the variable pump of the hydraulic system, Hydraulic energy quantitative motor of mechanical energy, motor and drive reducer, drive mixing device by reducer, mix concrete. The reducer will also fail. Many people don't know what to do when they encounter the failure of the reducer. Let's learn about the common failures of the reducer?

　　1、漏油:轴封漏油，轴封漏油主要是由于减速机使用不当造成的划痕或减速机输出轴划痕及异物缠绕所致。在这种情况下，有必要更换轴封或油封。减速机在使用过程中，油封内异物应及时清理干净。端盖与壳体连接处有漏油现象。这种类型的漏油主要是由减速机连接螺栓松动引起的。此时应及时拧紧端盖与壳体的连接螺栓或更换减速机，或更换端盖与壳体之间的o形圈。为了避免这种情况的再次发生，通常要定期检查螺栓的扭矩。电机与减速机联接处的漏油主要是由于电机与减速机安装时o形环密封不当造成的。此时需要更换电机与减速机连接处的o形环，并检查电机与减速机安装面是否有划痕。混合器正常运行时，请检查电机、减速器上安装的螺栓是否松动。

　　1. Oil leakage: oil leakage of shaft seal, which is mainly caused by scratches caused by improper use of reducer or scratches and foreign matter winding of output shaft of reducer. In this case, it is necessary to replace the shaft seal or oil seal. During the use of the reducer, foreign matters in the oil seal shall be cleaned up in time. There is oil leakage at the connection between the end cover and the housing. This type of oil leakage is mainly caused by loose connecting bolts of reducer. At this time, tighten the connecting bolts between the end cover and the housing or replace the reducer, or replace the O-ring between the end cover and the housing. In order to avoid the recurrence of this situation, it is usually necessary to check the torque of the bolt regularly. The oil leakage at the joint of motor and reducer is mainly caused by the improper sealing of O-ring during the installation of motor and reducer. At this time, it is necessary to replace the O-ring at the connection between the motor and the reducer, and check whether there is scratch on the mounting surface of the motor and the reducer. When the mixer is in normal operation, please check whether the bolts installed on the motor and reducer are loose.

　　2、异响在使用水泥搅拌机的过程中如果减速器出现异响，要做一个检查:检查减速器中是否有齿轮油;在油位观察窗口检查油位是否正常;释放少量油，观察是否有变黑变质作用，检查停留时间;检查减速机是否受到外力的影响。如果发现油中有大量铁屑，即减速器已损坏，则必须更换减速器，通常定期对减速器进行维护。

　　2. During the use of cement mixer, if there is abnormal noise in the reducer, a check shall be made: check whether there is gear oil in the reducer; check whether the oil level is normal in the oil level observation window; release a small amount of oil, observe whether there is blackening metamorphism, check the residence time; check whether the reducer is affected by external force. If a large amount of iron chips are found in the oil, that is, the reducer has been damaged, the reducer must be replaced, and the reducer is usually maintained regularly.
