自动加油综框导槽的应用

Application of the Heald Frame Guide Groove with Automatic Refueling

为保证喷气织机综框在导槽内平稳、可靠运行,设计一种自动加油综框导槽,分析新综框采用改性聚甲醛(POM)导槽的性能优势,介绍综框导槽结构组成及尺寸,提出综框导槽安装时必须保证综框两侧综框导槽平齐等注意事项,并以综框导槽样件3个月的上机测试验证其优势。指出:新设计的综框导槽材质采用改性聚甲醛代替尼龙66,通过改进结构实现自动加油功能;综框导槽耐磨性好、尺寸稳定性好、化学稳定性高,织机运行时润滑脂通过油孔均匀流入滑槽内,使得综框侧挡得到润滑;该设计精度较高、轻量化且更人性化,能保证综框在导槽内平稳、可靠运行,并延长其使用寿命。

In order to ensure that the heald frame of air-jet loom runs smoothly and reliably in the guide groove,a heald frame guide groove with automatic refueling is designed.The performance advantages of the new heald frame guide groove with modified POM are analyzed,the structure composition and size of heald frame guide groove are introduced,and the matters needing attention,for example,ensuring the heald frame guide groove on both sides of the heald frame are flush when installing the heald frame guide groove are put forward.The advantages of the design are verified by the test for three months of the sample piece of heald frame guide groove.It is pointed out that the modified POM is used instead of nylon 66 in the new design of heald frame guide groove,and the automatic refueling function is realized by improving the structure.The heald frame guide groove has good wear resistance,good dimensional stability and high chemical stability,and the grease evenly flows into the chute through the oil hole when the loom is running,so that the heald frame side plate is lubricated.The design has the advantages of high precision,light weight and more humanization,which can ensure the heald frame to run stably and reliably in the guide groove,and prolong the service life.
