Based on the stress analysis to spired axis mechanism,in the aspect of sliding part which smoothes through alveolus intersection, theresearch of parameters optimization, about the middle alveolus of spired axis andthe dimension of sliding part, has been studied. To the problem that the reverseportion at the both sides of spired axis lashed fiercely and fraies quickly, thearticle finely analyses the best curve of alveolus when adding cushiony spring atthe both sides.
在对螺旋轴机构进行受力分析的基础上,从滑块顺利通过齿槽交叉点的要求方面,对螺旋轴中间段齿槽和滑块的尺寸进行了参数优化分析;针对螺旋轴两端曲线齿槽反向段在高速工作时冲击大、磨损快的问题;从减少滑块在齿槽反向段运动的冲击方面,比较分析了圆弧、抛物线、三角函数等曲线作为螺旋轴齿槽反向段曲线的加速度,提出了较优的(来源:ABCab论bf文网www.abclunwen.com)反向段曲线。
