JF型环锭细纱牵伸装置性能研究 JF型环锭细纱牵伸装置性能研究 摘要 JF型环锭细纱牵伸装置性能研究 摘 要 环锭细纱机的牵伸装置经过数十年的发展，涌现出多种型式，但技术上最为成熟 的有四种，即SKF牵伸、INA．V牵伸、R2P牵伸和HP牵伸，这些牵伸装置均来自 国外技术，经我国科研人员和纺机配件厂改造后又形成R2V等牵伸形式，但均为上 述四种牵伸型式的衍化。由昆山景丰机械有限公司发明的专利产品JF型细纱牵伸装 置，在上下销结构、加压元件等方面进行了创新，经部分试用后，具有较好的效果。 做为一种新型的牵伸装置，目前尚缺少较为系统的理论和工艺规律的研究和总结。本 课题通过对JF形牵伸系统的结构进行理论分析和数学模拟，并对JF型牵伸和SKF 牵伸的性能进行了对比测试，找出了腰形牵伸的最佳工艺及适用范围。为JF型牵伸 系统的推广使用和改进提供一些参考。 本课题研究的内容：(1)JF型环锭细纱牵伸装置结构与理论分析，包括JF 型环锭细纱牵伸装置浮游区长度的计算、JF型环锭细纱牵伸装置的摩擦力界分 布、JF型环锭细纱牵伸装置变速模型；(2)JF型环锭细纱牵伸装置纺纱实验与 工艺优化；(3)JF型环锭细纱牵伸装置与SKF牵伸装置的对比实验。 关键词： 牵伸装置、数学模型、摩擦力界、回归分析、变速点 作 者：苏玉恒 指导老师：冯岑 A A Study ofJF Type Drafting Equipment Performance Ring Spinning Machine Abstraet A Study of JF Type Drafting Equipment Performance on Ring Spinning Machine Abstract The equipment on ring spinning machine came to the fore various types smce dozens of years，but there ale four types were the most mature，SKF type，INA—V type，R2P type and HP type，these equipment made by the foreign nation．In spite of created the various drafting equipment on the ring spinning by the domestic researcher and the spinning accessories plants，example R2V types，but all derived form the four types aforesaid．The IF type equipment is the patent product invented by KUN SHAN JING FENG MACHINE CO．LTD．Created the new structure of the top and bottom apron cradle，as well as the element of the press structure on this equipment．The JF type equipment have excelled performance Oll part probation．As a new type drafting equipment,there is few analysis and summary on the theory and art at present．This paper analyzes and mimics the theory and of the JF type equipment structure，and making comparison between IF type and SKF type，found the best-alt and the rang applied to．which will provide later science study and the production winl guidance． The main content of the paper is：(1)Analyzes and mimics the theory of the IF type equipment structure，include the calculate of the floating zone distance，friction force zone distribution and fiber speed change poin
