摘　　要：为了确定鸡蛋定向装置的最佳工作参数,研究输送辊材质及其表面粗糙度对鸡蛋定向运动的影响规律。结果表明,鸡蛋在铝合金辊上的水平偏转角最大,尼龙辊上水平偏转角最小;输送辊材质对鸡蛋轴向位移、导向杆作用距离无明显差异;碳钢辊、铝合金辊和有机玻璃辊的表面粗糙度对鸡蛋定向运动中的翻滚距离影响不明显,尼龙辊对翻滚距离的影响相对明显;鸡蛋的侧偏角在尼龙辊、碳钢辊和铝合金辊上的变化幅度不大,在有机玻璃上变化幅度相对明显。定向装置最佳工作参数:输送辊材质为碳钢、表面粗糙度等级为2、转动线速度70mm/s、直径40mm、间距15mm和导向杆角度30°。To determine the optimum working parameters of the egg orientation, the influence of convey roller＇s material and roughness on egg＇s directional movement was studied. The results showed that the horizontal deflection angle of the egg was the largest on the aluminum alloy roller and the smallest on the nylon roller. Convey rollers of different materials had no significant influence on the axial displacement and the guiding distance of guide rod, The surface roughness of carbon steel roller, aluminum alloy roller and organic glass roller had few effects on the rolling distance, the effect of nylon roller on that was relatively obvious. The change of the egg＇ s side-slip angle on the nylon roller, the carbon steel roller and the alumi-num alloy roller was not obvious, but that on the organic glass roller was relatively ohvious. The optimal parameters were determined： the material was carbon steel roller, surface roughness was level 2, the diameter was 40 mm, the spacing was 15 ram, the rotate speed was 70 mm/s and guide rod angle was 30%.
