摘　　要：为设计出能够高速运行的簇绒机主轴机构,对传统簇绒机主轴机构无法适应高速运行的原因进行分析,提出高速化主轴系统的构型设计需求和高速化实现方法。应用运动链再生法和组合法并结合高速化方法,提出3种主轴系统的构型设计方案。C_(1)方案利用双齿面同步带使主从轴相邻机构呈相反转向,增加与主轴转向相反的平衡轴以平衡传递到主轴的惯性载荷;C_(2)方案属于多连杆型,增加一组曲柄滑块机构以平衡竖直方向的惯性力;C_(3)方案采用齿轮传动,两组曲柄滑块水平对称放置,增加平衡飞轮以平衡竖直方向惯性力并储能。应用MATLAB软件对主轴机构的惯性载荷进行计算,结果表明,3种方案以1500 r/min高速运行时,主轴最大动反力均比传统簇绒机的小,且C_(1)的最大动反力降低了约72.5%。To design a tufting machine spindle mechanism that can run at high speed,the reasons why traditional tufting machine spindle mechanism cannot be adapted to high speed operation were analyzed,and a design requirement for high-speed spindle system configuration and a high-speed implementation method were proposed.By applying the kinematic chain regeneration and combination methods combined with the high-speed method,three spindle system configurations were proposed.In the C_(1)solution,a double-toothed synchronous belt is used to make the adjacent mechanisms of the master and slave shafts steer in opposite directions,and a balance shaft is added to balance the inertia load transferred to the main shaft.The C_(2)solution is of the multi-link type,with an additional set of crank slider mechanisms to balance the inertial forces in the vertical direction.The C_(3)solution uses a gear drive,two sets of crank sliders placed horizontally and symmetrically,and a balance flywheel added to balance vertical inertia forces and store energy.The inertia load of the spindle mechanism was calculated by MATLAB software.The results show that the maximum dynamic reaction force of the spindle is smaller than that of the traditional tufting machine for all three solutions running at 1500 r/min,and the maximum dynamic reaction force of C_(1)solution is reduced by about 72.5%.
