摘　　要：槽轮机构广泛应用于各种机械中。针对灯笼状荔枝果肉获取机械中的槽轮机构,通过动力分析建立槽轮工作阻力矩和拨盘驱动力矩间关系的数学模型,利用Pro/E软件建立槽轮机构的三维参数化模型,并进行静态应力分析和全局敏感度分析。结果表明:槽轮工作中受到的静态应力小于材料的抗剪刚度;槽轮的厚度越大,在同样的工作载荷下所受到的静态应力就越小。上述结果给送料机构的改进设计和制造提供了依据。Geneva wheel mechanism is widely used in various machines.This article studies the feeding mechanism of litchi flesh processing machine of lantern shape.By means of dynamic analysis,mathematical model of resistance torque and drive torque is established.Using Pro /E software,3D parameter models of geneva mechanism is set up and static stress and overall sensitivity are analyzed as well.The results show that the max static stress of geneva is lower than shear stiffness of material;and the thicker the geneva is,the lower static stress it shows.The above results provide foundation for the improvement of the design and manufacture of feeding mechanism.
