Roll Crusher Main Drive System Design Abstract The roller crusher main drive system is composed of the cone - cylinder gear reducer and the third-class gear transmission within institutions .The system is simple in the principle, easy to realize and reliable at work. The reducer is the general slowdown framework so it has inter-operable. As the design of speed reducer is the main part of? the roller crusher main drive system, the design will be through comparison and optimization improvements for some general reducer to meet a good design requirements.The design focuses mainly on the design of speed reducer.?Firstly, this design was carried out in the overall design, established a transmission program, allotted the transmission ratio at all levels and described the reasons for such a transmission choice.?Secondly, the design was based on the macro-design , analysed and designed all transmission components which were named the cone gears drive, the helical gears transmission and the gears drive within institutions.Third,? the high-speed reducer shaft, the intermediate shaft and the low speed shaft had been designed respectively in detail. Then a general framework of the reducer were establish and the reducer assembly drawings and a number of parts drawing were mapped.Finally, the 1-2 special parts selected conducted a check
