搅拌车上的配件是比较多的，其中重要的是液压三大件：减速机、液压泵、液压马达，今天我们主要来了解一下减速机，减速机分为进口和国产两种，一般小型的搅拌车多使用国产品牌，而大型的多使用进口品牌，下面我们就来了解一下进口减速机的知识。

There are many accessories on the mixer truck, among which the three major hydraulic parts are important: reducer, hydraulic pump and hydraulic motor. Today we mainly want to know about the reducer, which is divided into imported and domestic. Generally, small mixer trucks mostly use domestic brands, while large ones use imported brands. Let's learn about the knowledge of imported reducer.

自动上料搅拌机的主要运输介质是预拌混凝土，一般多为湿料运输，在运输效率方面的要求是很高的因为湿料的有效期是比较短的，超过了就会凝结成块，失去其作用，减速机一般主要由箱体、减速机附件、齿轮、轴及轴承等组合成的。

The main transportation medium of the automatic feeding mixer is ready mixed concrete, which is generally wet material transportation. The requirements for transportation efficiency are very high, because the validity period of wet material is relatively short, and it will condense into blocks and lose its function if it is exceeded. The reducer is generally composed of box, reducer accessories, gears, shafts and bearings.

箱体：它是减速机的要组成部分，是传动零件的基座，必须具备足够的强度和刚度，箱体通常用灰铸铁制作，对于载或者有冲击载荷的减速机也可采用铸钢箱体，单体生产的减速机，为了简化制作工艺，降低生产成本，可采用钢板焊接的箱体。

Box: it is an important part of the reducer and the base of the transmission parts. It must have sufficient strength and stiffness. The box is usually made of gray cast iron. For the reducer with or without impact load, it can also use cast steel box. For the reducer produced by monomer, in order to simplify the manufacturing process and reduce the production cost, the box welded with steel plate can be used.

减速机附件：减速机附件包含的东西比较多，比如加速机的润滑油，平时使用过程中要注意观察油面的高度、排油、注油等问题。

Reducer accessories: reducer accessories contain many things, such as the lubricating oil of the accelerator. During normal use, pay attention to the height of the oil surface, oil drainage, oil filling and other issues.

齿轮、轴及轴承组合：小齿轮与轴制成一体，称齿轮轴，这种结构用于齿轮直径与轴的直径相关不大的情况下，如果轴的直径为d，齿轮齿根圆的直径为df，则当df-d≤6——7mn时，应采用这种结构，而当df-d＞6——7mn时，采用齿轮与轴分开为两个零件的结构，如低速轴与大齿轮，此时齿轮与轴的轴向固定平键连接，轴上零件利用轴肩、轴套和轴承盖作轴向固定，两轴均采用了深沟球轴承。

Gear, shaft and bearing combination: the pinion is integrated with the shaft, which is called gear shaft. This structure is used when the diameter of the gear is not related to the diameter of the shaft. If the diameter of the shaft is D and the diameter of the gear root circle is DF, this structure should be adopted when df-d ≤ 6-7mn, and when df-d > 6-7mn, the structure that the gear and shaft are separated into two parts, such as low-speed shaft and big gear, At this time, the gear is connected with the axial fixed flat key of the shaft, and the parts on the shaft are axially fixed by the shaft shoulder, shaft sleeve and bearing cover. Deep groove ball bearings are used for both shafts.

这种进口减速机具有设计独特、使用寿命长、噪音低、安全方便等优点，驾驶搅拌车的车主可以了解一下这些知识。想要了解更多内容可以电话联系我们或者关注我们的网站http://www.zkhntjbj.com，我们的工作人员会及时与您取得联系。

This imported reducer has the advantages of unique design, long service life, low noise, safety and convenience. The owner of the mixer can learn about this knowledge.
