摘  要:现有产品的切纵流脱粒清选装置传动系统设计可靠性较差,脱粒分离传动系统布局较复杂,脱粒滚筒转速固定,对作物的适应性较差。为此,以太湖TH988型切纵流联合收割机为研究对象,根据切纵流脱粒清选装置工作部件的作业流程和相互位置关系,结合传动系统设计原理制定新的传动方案,并对关键传动参数进行验证,在脱粒分离装置动力布局上,设计了一种两挡换向传动箱。优化后的脱粒清选装置经过制造加工、装配到台架上,对其传动系统进行试验,通过检测发现:工作部件的转速满足工作要求,整个传动系统运行通畅,为切纵流联合收获机传动系统设计提供了依据。A stable and reliable threshing separation transmission system can increase the threshing performance of the drum and at the same time contribute to the patency of the whole harvesting operation.Summarize and analyze the shortcomings of the current longitudinal flow threshing separation device drive system,and then take the Taihu TH988 type longitudinal flow combined harvester as the research object,according to the mutual relationship between the flow roller,vertical flow roller and the transmission system design principles.A two-speed reversing gearbox was used,and the working parameters of the transmission components were checked on the basis of the performance requirements of the combine harvester.
