攪拌車進口減速機知識講解
攪拌車上的配件是比較多的，其中很重要的是液壓三大件：減速機、液壓泵、液壓馬達，今天我們主要來了解一下減速機，減速機分為進口和國產兩種，一般小型的攪拌車多使用國產品牌，而大型的多使用進口品牌，下面自上料攪拌車廠家就來講解一下進口減速機的知識。
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.
減速機一般主要由箱體、減速機附件、齒輪、軸及軸承等組合成的。
Reducer is generally composed of box, reducer accessories, gears, shafts and bearings.
看箱體：它是減速機的重要組成部分，是傳動零件的基座，須具備足夠的強度和剛度，箱體通常用灰鑄鐵制作，對于重載或者有沖擊載荷的減速機也可采用鑄鋼箱體，單體生產的減速機，為了簡化制作工藝，降低生產成本，可采用鋼板焊接的箱體。
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.
減速機附件：減速機附件包含的東西比較多，比如加速機的潤滑油，平時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.
然后是齒輪、軸及軸承組合：小齒輪與軸制成一體，稱齒輪軸，這種結構用于齒輪直徑與軸的直徑相關不大的情況下，如果軸的直徑為d，齒輪齒根圓的直徑為df，則當df-d≤6——7mn時，應采用這種結構。
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.
而當df-d＞6——7mn時，采用齒輪與軸分開為兩個零件的結構，如低速軸與大齒輪，此時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。
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.
這種進口減速機具有設計獨特、使用壽命長、噪音低、安全方便等優點，駕駛攪拌車的車主可以了解一下這些知識，可以關注我們的網站http://m.bflrsn.cn為您提供需求信息。
