【摘要】 本文分析了直线刃型切刀的不足。建立了等角螺线刃型切刀的刃口曲线方程 ,确定了切刀切割肉料不产生滑切的条件为切刀的切割角不大于肉料对刀刃的摩擦角。通过对比试验表明 ,切割角为40°的等角螺线切刀功耗最小、肉料升温最慢更多还原

【Abstract】 In this paper,the disadvantages of linear edge cutter were analyzed,and the curve equations of logarithmic helix cutter were set up The un_sliding requirement that the cutting_angle of cutter was no less than the friction_angle of meant stuff to the edge of a knife was determined Contract experiments showed that the power consume of logarithmic helix cutter with 40°cutting_angle was best,and stuff temperature raise was slowest更多还原
