收割机搅龙中拨杆座与偏心轴的磨损原因

The wear cause of the poke rod bedplate and the eccentric shaft in the harvester′s agitating auger

针对收割机搅龙中拨杆套与偏心轴磨损的实际情况，对收割机搅龙的主要构件进行运动学和力学分析，建立起函数式。研究发现该机构中偏心距与角速度和摩擦力之间的密切关系，从而找出磨损原因，并对该机构的设计提出了一些建议。实际证明。

In order to investigate the wear cause of the poke rod gaine and eccentric shaft in the harvester′s agitating auger,the main construction′s movement and mechanics of the agitating auger used in the harvester′s agitating auger are analyzed,and a function is set up. The relationship between the eccentric distance and angular velocity and friction are found out,some suggestions about the design of the construction are made.
