The rotary filed tiller is a kind of universal, articular farm machine. It has adopted the measure of tractor-mounted and side chain drive and can be used for the tillage and cultivation on the plain,mountains regins, hilly land and so on. The main task of this designing is to design the mechanical part of the rotary tiller’s drive and work and so on . The part of the rotary tiller’s drive is made of gear and taper-gear and chain-gear and the part of the rotary tiller’s work is made of tine and shaft .The motor drives the part of the rotary tiller’s drive and drives the part of the rotary tiller’s work to till filed,mountains regins and hilly land which is the larger rotary tillers can not be used .This retory filed tiller is easy to operate and is not demand of high technique .It can be go with the state of China. This thesis illustrates how to design and compute the parts of the rotary tiller’s drive, especially the process of how to design the three main parts which is middle gear drive,side chain drive,the tine carrier and shaft. It also adopts the parts of spline shaft ,taper-rolling bearing ,ball bearing ,dupiex chain and so on. Key words: rotary tiller; tine;side chain drive;middle gear drive; bearing 4
