Automatic feeding mixer explains the knowledge of imported reducer

自動(dòng)上料攪拌機(jī)的主要運(yùn)輸介質(zhì)是預(yù)拌混凝土，一般多為濕料運(yùn)輸，在運(yùn)輸效率方面的要求是很高的因?yàn)闈窳系臅r(shí)間是比較短的，超過了就會(huì)凝結(jié)成塊，失去其作用，攪拌車上的配件是比較多的，其中更重要的是液壓三大件：減速機(jī)、液壓泵、馬達(dá)，下面我們就主要來了解進(jìn)口減速機(jī)的知識(shí)。減速機(jī)分為進(jìn)口和國產(chǎn)兩種，一般小型的攪拌車多使用國產(chǎn)企業(yè)，而大型的多使用進(jìn)口企業(yè)，減速機(jī)一般主要由箱體、減速機(jī)附件、齒輪、軸及軸承等組合成的。

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.

自動(dòng)上料攪拌機(jī)看箱體：它是減速機(jī)的重要組成部分，是傳動(dòng)零件的基座，一定要具備足夠的強(qiáng)度和剛度，箱體通常用灰鑄鐵制作，對(duì)于重載或者有沖擊載荷的減速機(jī)也可采用鑄鋼箱體，單體生產(chǎn)的減速機(jī)，為了簡化制作工藝，降低生產(chǎn)成本，可采用鋼板焊接的箱體。

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.

減速機(jī)附件：減速機(jī)附件包含的東西比較多，比如加速機(jī)的潤滑油，平時(shí)使用過程中要注意觀察油面的高度、排油、注油等問題。

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.

自動(dòng)上料攪拌機(jī)，然后是齒輪、軸及軸承組合：小齒輪與軸制成一體，稱齒輪軸，這種結(jié)構(gòu)用于齒輪直徑與軸的直徑相關(guān)不大的情況下，如果軸的直徑為d，齒輪齒根圓的直徑為df，則當(dāng)df-d≤6——7mn時(shí)，應(yīng)采用這種結(jié)構(gòu)，而當(dāng)df-d＞6——7mn時(shí)，采用齒輪與軸分開為兩個(gè)零件的結(jié)構(gòu)，如低速軸與大齒輪，此時(shí)齒輪與軸的軸向固定平鍵連接，軸上零件利用軸肩、軸套和軸承蓋作軸向固定，兩軸均采用了深溝球軸承。這種進(jìn)口減速機(jī)具有設(shè)計(jì)獨(dú)特、使用壽命長、噪音低、方便等優(yōu)點(diǎn)。

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.
