双偏心套传动摆辗机摆头多叶玫瑰线运动轨迹研究

Research of Forming Trajectory of Multi-branches Rose Curve of Double Eccentric Sets Transmission for Orbital Forming Press Head

建立了内外偏心套传动摆辗机摆头的矢量运动模型,利用Matlab软件对异速反向的内外偏心套的运动规律进行了仿真模拟,当外偏心套转速ω_1>0,内偏心套转速ω_2<0,且ω_1≠|ω_2|时,摆头运动轨迹为多叶玫瑰线,分析多叶玫瑰线轨迹的运动形成过程,并对多叶玫瑰线的叶片数量和轨迹规律进行了研究。

The vector motion model is built to study the trajectory tracking of the orbital forming press head, the motion trajectory of the orbital head with different speed and direction is simulated by using MATLAB software, the motion trajectory is multi - branches rose curve when the outer eccentric speed to1〉 0, and the in- ner eccentric speed ω2 〈0, and ω1 ≠ │ω2│. The formation process of multi -branches rose curve trajectory mo- tion are analyzed, the branch numbers of multi - branches rose curve and the law of the its trajectory are stud- ied.
