【摘要】：针对现有碳纤维立体织机引纬机构剑杆运动加速度波动剧烈,导致剑杆运动振动,运动平稳性差,提出采用减小齿轮模数同时增加异相位啮合齿轮的方法来提高引纬机构的运动稳定性,并在ADAMS软件中对不同模数、齿轮数和不同相位的几种引纬机构方案进行动力学仿真对比分析。实验结果表明,两个齿轮同相位传动改为异相位传动,传动动力性能可以得到一定的提高,但对于模数较大的齿轮齿条传动改善效果不明显;采用减小齿轮模数同时增加异相位啮合齿轮的方法,则可以显著提高齿轮齿条啮合传动动力性能,加速度在各频率的波动幅值平均降低25%。
[Abstract]:Aiming at the rapier motion acceleration fluctuation of the weft insertion mechanism of the existing carbon fiber stereoscopic loom, the rapier motion vibration is caused and the motion stability is poor. In order to improve the motion stability of the weft insertion mechanism, the method of reducing the gear modulus and increasing the misphase meshing gear is proposed to improve the motion stability of the weft insertion mechanism. Several schemes of gear number and different phase weft insertion mechanism are compared and analyzed by dynamic simulation. The experimental results show that the power performance of the two gears can be improved by changing the same phase transmission to the phase position transmission, but the effect on the gear rack transmission with larger modulus is not obvious. The dynamic performance of gear rack meshing transmission can be significantly improved by reducing the gear modulus and increasing the abnormal phase meshing gear, and the fluctuation amplitude of acceleration at each frequency can be reduced by 25% on average.
