搅拌车进口减速机知识讲解
搅拌车上的配件是比较多的，其中很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企业，而大型的多使用进口企业，下面自上料搅拌车厂家就来讲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 very important: reducer, hydraulic pump and hydraulic motor. Today we mainly want to know about the reducer. The reducer is divided into imported and domestic. Generally, small mixer trucks mostly use domestic brands, while large ones use imported brands. Let's talk about the knowledge of imported reducer from the charging mixer truck manufacturer.
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。
Reducer is generally composed of box, reducer accessories, gears, shafts and bearings.
看箱体：它是减速机的重要组成部分，是传动零件的基座，须具备足够的强度和刚度，箱体通常用灰铸铁制作，对于重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。
Look at the box: it is an important part of the reducer and the base of the transmission parts, which must have sufficient strength and stiffness. The box is usually made of gray cast iron. For the reducer with heavy load or 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.
然后是齿轮、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。
Then there is the combination of gear, shaft and bearing: the pinion and shaft are made into one, 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.
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。
When df-d > 6-7mn, 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 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、方便等优点，驾驶搅拌车的车主可以了解一下这些知识，可以关注我们的网站https://www.jfjiaobanche.com为您提供需求信息。
