摘  要:
针对弹齿滚筒式捡拾装置在工作过程中弹齿变形现象,对弹齿滚筒式捡拾装置弹齿进行静力学分析,以寻求解决的途径。通过对捡拾装置弹齿在3个工作阶段上的载荷进行分析后,获得各工作阶段弹齿的受力简图,通过比较判断出在捡拾升运阶段弹齿受力比较复杂。以9KJ-1.4A型压捆机捡拾装置为实例,经过计算在有随机载荷和无随机载荷时弹齿齿臂末端的应力情况,得出结论:在没有随机载荷的情况下,齿根处应力远小于其许用应力,弹齿产生弹性变形,有足够的强度;当有随机载荷时,对弹齿产生冲击,若随机载荷过大,垂直于弹齿轴向的分力大于24N,则弹齿会产生塑性变形。对捡拾装置进行静力分析,可为捡拾装置整体结构优化设计供理论依据。

摘  要:
Doing static analysis is necessary for spring- finger cylinder pickup collector. Force diagrams show that the forces of spring- finger on pick up stage are more complex than the other stages. Without random force,the stress of spring- finger root is greatly less than allowable stress according to calculation results and spring- fingers have elastic deformation,they have enough strength; random force has impact to spring- fingers,when the component force perpendicular to spring- finger is greater than 24 N,spring- fingers have plastic deformation. Doing the static analysis will provide theoretical basis for structural optimization of spring- finger cylinder pickup collector.
