E512、E514联合收割机传动挠性联轴片损坏后,则使用国产的挠性联轴片,因机械强度不够而容易损坏。每年麦、豆收获,平均一台联合收割机损坏挠性联轴片2～3片,而更换一个挠性联轴片需停机4小时左右。我场共有E512、E514联合收割机94台,就此一项故障耽误收获进度1000多垧,故障修理费1万多元。 解决方法是:将该机的挠性联轴片改制成刚性花链接盘,如图所示。经使用证明:此改装工作可靠,提高了作业效率。 E512, E514 combine harvester transmission flexible coupling piece is damaged, the use of domestic flexible coupling piece, due to mechanical strength is not enough and easily damaged. Each year wheat, beans harvested, an average of a combined harvester damaged flexible shaft 2 to 3, and replace a flexible shaft to be shut down about 4 hours. My field has a total of E512, E514 combine harvester 94, this a delay of harvest progress of more than 1,000 垧, repair costs more than 10,000 yuan. The solution is: the machine’s flexible coupling piece into a rigid flower chain plate, as shown. Proved by the use: This modification work is reliable, improve work efficiency.
