The main transportation medium of self loading mixer is premixed concrete, which is generally wet material transportation. The requirement of transportation efficiency is very high, because the period of validity of wet material is relatively short. If it exceeds, it will condense into blocks and lose its function. There are many accessories on the mixer, among which the most important are three hydraulic parts: reducer, hydraulic pump and hydraulic motor, Now we mainly to understand the knowledge of imported reducer. There are two kinds of reducers: imported and domestic. Generally, domestic brands are used in small mixer trucks, while imported brands are used in large mixer trucks. Reducers are mainly composed of box, reducer accessories, gears, shafts and bearings.

From the feeding mixer, first look at the box: it is an important part of the reducer. It is the base of transmission parts and must have sufficient strength and stiffness. The box is usually made of gray cast iron. For the reducer with heavy load or impact load, the cast steel box can also be used. For the reducer produced by single body, in order to simplify the manufacturing process and reduce the production cost, the box can be used, The box can be welded with steel plate.
加快机附件：加快机附件包罗的工具比拟多，比方加快机的光滑油，日常平凡操纵进程中要注重察看油面的高度、排油、注油等题目。
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 issues.

This structure is used when the diameter of the gear is not closely 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 gear and shaft are separated into two parts, such as the low speed shaft and the large gear. At this time, the gear and the shaft are connected by the axial fixed flat key. The shaft parts are fixed axially by the shaft shoulder, the shaft sleeve and the bearing cover. The deep groove ball bearings are used for both shafts. The imported reducer has the advantages of unique design, long service life, low noise, safety and convenience.
