摘要
圆管编织机锭子采用双导向块导向沿‘∞’字形轨迹运动,锭子几何中心运行轨迹与轨道中心线不完全重合,其偏移量引起锭子在理想轨迹左右振荡并导致编织机运行不稳定,严重影响编织机生产效率。分析引起锭子运行轨迹偏移的关键因素,并建立锭子运行数学模型,提出一种锭子几何中心沿等圆相切的轨迹线运行的理想轨道设计方案。该方案锭子运动采用单导向块导向,轨道中心线采用首尾相切的非等圆,且轨道等宽,实现锭子几何中心沿等圆相切轨迹运行。该设计方案可有效减小锭子在运行过程中的振荡,提高编织机运行速率和平稳性。
The carrier of the circular braider go along ＇∞＇-shape trajectory guided by two guide pads. The trajectory of the carrier geometric center is not exactly coincide with the center line of the track. Carrier oscillates near ideal trajectory induced by carrier eccentricity, which then induces unstable operation and deeply affects the productive efficiency of the braider. Key factors causing trajectory deviation are analyzed. The carrier operation mathematic model is established. A design scheme of ideal track that carrier geometric center go along the trajectory of tangent equal circles is proposed. The carrier guided by a guide pad. The center line of the track applies a set of non circulars , which are tangent in series, The track has the equal width. That the carrier geometric center go along the trajectory of tangent equal circles is realized. The scheme which efficiently reducing the oscillation of the carrier significantly increases the speed and stability of the circular braider.
