It is forced horizontal-axis concrete mixer, forced one of concrete mixer can not only the mixing of dry, rigid concrete, and can stir light weight aggregate concrete, can make concrete achieve strong mixing effect, stirring very evenly, productivity is high, quality is good, the cost is low. It is the present domestic relatively new mixer, the machine has compact structure, good appearance. Its main composition structure including: agitator, stirring transmission system, loading, unloading system, water supply system, rack and mobile system, electric control system, lubrication system, etc. This paper is to design the main components of Concrete Mixer, and mainly covers program determination of overall structure, calculating of mixer power, selection of electric machinery and calculating of main parameters, calculating of transmission ratio and shaft dynamic parameters; design and check of reducer high speed shaft, mixer shaft and stirring shaft,as well as selection of mixer reducer,including confirming necessary rated power of reducer, checking heat balance of allowable power,calculating band,selecting coupling, choosing keys,drawings concrete mixer assembly and parts mapping. Keyword: concrete mixer, retarder, the channel。 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc324078435 摘 要 PAGEREF _Toc324078435 \h i HY
