Automatic feeding mixer explains the knowledge of imported reducer

自动上料赢咖7注册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时间是比较短的，超过了就会凝结成块，失去其作用，搅拌车上的配件是比较多的，其中更重要的是液压三大件：减速机、液压泵、马达，下面我们就主要来了解进口减速机的知识。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，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 loading mixer is ready mixed concrete, which is generally wet material transportation. The requirements for transportation efficiency are very high, because the time of wet material is relatively short, and it will condense into blocks and lose its function. There are many accessories on the mixer, among which the three major hydraulic parts are more important: reducer, hydraulic pump and motor, Now let's mainly understand the knowledge of imported reducer. There are two types of reducers: imported and domestic. Generally, domestic brands are mostly used for small mixer trucks, while imported brands are mostly used for large ones. Reducers are generally mainly composed of boxes, reducer accessories, gears, shafts and bearings.

自动上料赢咖7注册看箱体：它是减速机的重要组成部分，是传动零件的基座，一定要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。

The automatic feeding mixer first looks at the 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 heavy load or impact load, it can also use cast steel box. For the reducer produced by single unit, in order to simplify the manufacturing process and reduce the production cost, Steel plate welded box 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 a lot of 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 problems.

Automatic feeding mixer, followed by gear, shaft and bearing combination: the pinion is integrated with the shaft, which is called gear shaft. This structure is used when the gear diameter is not related to the shaft diameter. 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 gear and shaft are separated into two parts, such as low-speed shaft and large gear. At this time, the axial fixed flat key of the gear and shaft is connected. The parts on the shaft are axially fixed by shaft shoulder, shaft sleeve and bearing cover. Both shafts adopt deep groove ball bearings. This imported reducer has the advantages of unique design, long service life, low noise, convenience and so on.
