攪拌車上的配件是比較多的，其中重要的是液壓三大件：減速機(jī)、液壓泵、液壓馬達(dá)，今天我們主要來了解一下減速機(jī)，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)，下面我們就來了解一下進(jìn)口減速機(jī)的知識。

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.

自動上料攪拌機(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)闈窳系挠行谑潜容^短的，超過了就會凝結(jié)成塊，失去其作用，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 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.

箱體：它是減速機(jī)的要組成部分，是傳動零件的基座，必須具備足夠的強(qiáng)度和剛度，箱體通常用灰鑄鐵制作，對于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。

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.

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 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.

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。

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.

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)，駕駛攪拌車的車主可以了解一下這些知識。想要了解更多內(nèi)容可以電話聯(lián)系我們或者關(guān)注我們的網(wǎng)站http://www.wishnailspa.com，我們的工作人員會及時(shí)與您取得聯(lián)系。
