混凝土搅拌车在使用过程中会呈现减速机、齿轮泵级马达漏油等现象，今天关于混凝土搅拌车的减速机漏油以及维修方法进行介绍

During the use of concrete mixer truck, there will be oil leakage of reducer and gear pump motor. Today, we will introduce the oil leakage and maintenance methods of reducer of concrete mixer truck

1、混凝土搅拌车减速机漏油原因阐明

1. Explanation of oil leakage of reducer of concrete mixer

(1)在封闭的减速机箱内，每一对齿轮相啮合及齿轮浸入油中搅油都发生热量。跟着运转时间的长，使减速箱内温度逐增加，箱体内润滑油经飞溅，洒在减速机箱体内壁，因润滑油的粘度随温度升高而低落，油的透性更强，在箱内压力浸箱面或轴伸密封不严处渗漏。

(1) In the closed reduction case, heat is generated when each pair of gears mesh and the gears are immersed in oil to stir the oil. With the long operation time, the temperature in the reduction box increases gradually, and the lubricating oil in the box splashes and sprinkles on the inner wall of the reduction box. Because the viscosity of the lubricating oil decreases with the increase of temperature, the oil permeability is stronger, and it leaks at the pressure immersed box surface in the box or the shaft extension seal is not tight.

(2减速机结构不公道引起漏油。如设计的减速机没有通风罩或通风罩太小，减速机无法实现均压，也会造成箱内压力升高

(2) the unreasonable structure of the reducer causes oil leakage. If the designed reducer has no ventilation hood or the ventilation hood is too small, the reducer cannot achieve pressure equalization, which will also cause the pressure in the box to rise

(3)减速机事情情况恶劣引起漏油。如情况多尘造成通风罩通风结果差，不能实现均压，高温及有害介质，使密封件老

(3) The reducer is in bad condition, causing oil leakage. If the ventilation result of the ventilation hood is poor due to too much dust, pressure equalization cannot be realized, high temperature and harmful media will make the seal old

(4)装配质量达不到要求，在维修安装减速机封盖时团结面密封欠好，也会呈现漏油现象。

(4) If the assembly quality fails to meet the requirements, the sealing of the unity surface is not good when repairing and installing the reducer cover, which will also show oil leakage.

2、防备混凝土搅拌车减速机漏油的法方法

2. Method for preventing oil leakage of reducer of concrete mixer

(1)均压。减速机漏油主要是由于减速机箱内压力增加所引起，因此减速机应设有相应的通风罩，以实现箱内和箱外压力

(1) Equalizing pressure. The oil leakage of the reducer is mainly caused by the increase of pressure in the reducer box. Therefore, the reducer shall be equipped with corresponding ventilation hood to realize the pressure inside and outside the box

速机较量大，通风罩不能太小。通风罩巨细的轻便查抄要领是：打开通风罩上盖，减速机以高速持续运转几分钟之后，用压差较大时，说明通罩小，则应改换通风罩，确保均压。对在恶劣情况事情的减速机应经常查抄通风罩的通风结果，发明

Due to the large competition of speed machines, the ventilation hood should not be too small. The key points of light inspection of the size of the ventilation hood are: open the upper cover of the ventilation hood, and after the reducer continues to operate at high speed for several minutes, if the pressure difference is large, it indicates that the ventilation hood is small, then the ventilation hood should be replaced to ensure pressure equalization. Check the ventilation results of the ventilation hood frequently for the reducer in bad conditions

(2)导流。减速机在高速运转时，由于齿轮浸在油池中，在旋转时将油带起飞溅到箱体内壁，要使飞溅到箱体内壁的油尽及轴头密封处存留，以防油逐渐沿上下箱体之间及轴头浸出来。可在减速机上下箱体团结面处开回油槽，在轴头设计出油轴头处粘一半圆槽，使溅到上盖的油顺半圆槽两头流到下箱中，使飞溅到箱体上的油不会漏出。

(2) Diversion. When the reducer is running at high speed, because the gear is immersed in the oil pool, the oil belt will take off and splash on the inner wall of the box during rotation. The oil splashed on the inner wall of the box and the seal of the shaft head shall be retained to prevent the oil from gradually soaking out between the upper and lower boxes and the shaft head. The oil return groove can be opened at the joint surface of the upper and lower boxes of the reducer, and the oil is designed at the shaft head. The half round groove is stuck at the shaft head to make the oil splashed on the upper cover flow into the lower box along the two ends of the half round groove, so that the oil splashed on the box will not leak out.
