3、and the disadvantages of planet gear transm ission, crank connectinglink mechanism andwobble box transmission, to overcome theweakness of crank connecting link mechanism and wobblebox transmission whichmade the cutter enduring lateral force and easy to break, the condition of realization of the cutt
4、erreciprocal linearmotion was got afteranalysis of planetgearmechanism motion, and the planetgear transm ission ofDongnullfanghong 4LZ - 2. 5 combinewas designed according to the condition and the actualsituation in thepaper. The designedtransmission which was checked by contact fatigue strength and
5、 bending fatigue strength was safe and reliable. Thatwas afeasible project on improving transmission in combine.Key words: planet gearmechanism; motion analysis; design; Dongfanghong 4LZ - 2. 5 combinenull70null2011 M4null null null null null null null null null null null null null null jnull null null null null null null null null null null null null null null null4
