磁悬浮式驱动织针的原理及结构设计

Principle and structural design of magnetic levitation driven needle

在传统的针织机选针提花原理基础上,提出了电磁—永磁悬浮的新型悬浮织针模式,并将其引入选针机构,提出了轴向磁悬浮式织针驱动理论。该理论的核心是将电磁力直接作用在织针上,从而实现了从传统的多级传动到零传动模式的织针驱动原理。详细论述磁悬浮式织针模型运动分析和磁悬浮式织针装置结构设计,为进一步研究新型针织机的选针驱动原理提出一种参考。

Byased on the jacquard selection principle of traditional knitting machine,this paper puts forward a new type of electromagnetic and permanent magnetic needle suspending way,introduces it into the selection devices,and presents the axial magnetic levitation driven needle theory.The core technique of this theory is to apply the electromagnetic force directly on needles,which realizes the 'zero driving'from'Multi-level driving'.It discusses in detail the motions of magnetic levitation driven needle model and structural design,which can be a reference for further study of new type of needle selection driving principle.
