| 摘 要： | 通过行星齿轮传动机构和曲柄连杆、摆环传动机构的优缺点对比,针对曲柄迮杆、摆环传动机构使刀杆受到侧向的分力,容易导致刀杆断裂和故障率高等缺点,建立行星齿轮机构输出端运动方程,并进行运动分析.得到了割刀实现往复直线运动的条件.根据这个条件和实际情况,设计了东方红4LZ-2.5联合收割机的行星齿轮传动机构,经接触疲劳强度和弯曲疲劳强度校核,该传动机构安全可靠.为联合收割机传动机构的改进提供可行方案.

| Abstract: | Based on comparison of the advantages and the disadvantages of planet gear transmission,crank connecting link mechanism and wobble box transmission,to overcome the weakness of crank connecting link mechanism and wobble box transmission which made the cutter enduring lateral force and easy to break,the condition of realization of the cutter reciprocal linear motion was got after analysis of planet gear mechanism motion,and the planet gear transmission of Dongfanghong 4LZ-2.5 combine was designed according to... |
