padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">多臂装置是无梭织机开口机构的一种形式,是无梭织机的重要组成部分。</span></p><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"><p style="max-inline-size: 100%; clear: both; min-height: 1em; cursor: text; text-indent: 2em; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;"><span style="max-inline-size: 100%; margin: 0px; padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 一、多臂装置的作用</span></p><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"><p style="max-inline-size: 100%; clear: both; min-height: 1em; cursor: text; text-indent: 2em; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;"><span style="max-inline-size: 100%; margin: 0px; padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 多臂装置是织机五大运动的主要部件———开口装置中的一种,它的作用是把经纱(或丝)通过综框分成上下两层,以形成梭口,供织机引纬系统引纬,然后再闭口,使经、纬纱交织,周而复始,完成面料的织造。</span></p><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"><p style="max-inline-size: 100%; clear: both; min-height: 1em; cursor: text; text-indent: 2em; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;"><span style="max-inline-size: 100%; margin: 0px; padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; 二、应具备的条件</span></p><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"><p style="max-inline-size: 100%; clear: both; min-height: 1em; cursor: text; text-indent: 2em; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;"><span style="max-inline-size: 100%; margin: 0px; padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; (1)多臂装置本身无动力源,其完成运动的动力来自织机。传动的方式可通过齿轮、同步齿形带等来传递。</span></p><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"><p style="max-inline-size: 100%; clear: both; min-height: 1em; cursor: text; text-indent: 2em; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;"><span style="max-inline-size: 100%; margin: 0px; padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; (2)多臂装置应与织机保持同步运动,确保织机主轴传动一圈,多臂带动综框形成一次梭口,完成一次循环织造。目前使用的绝大部分多臂装置,是复动式结构,织机转动一圈,多臂只转动半圈,形成一次梭口。</span></p><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"><p style="max-inline-size: 100%; clear: both; min-height: 1em; cursor: text; text-indent: 2em; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;"><span style="max-inline-size: 100%; margin: 0px; padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; (3)多臂装置应具有信号阅读装置,即通过各种形式机构将满足面料织造工艺的排列信号,按规律的接收并输给多臂执行机构,继而带动综框完成开口运动。常用的信号阅读装置有以下几种:穿孔纹纸式、纹钉纹板式、电子信号式。</span></p><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"><p style="max-inline-size: 100%; clear: both; min-height: 1em; cursor: text; text-indent: 2em; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;"><span style="max-inline-size: 100%; margin: 0px; padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; (4)应具有提综及回综执行机构。对积极式多臂来讲,因执行机构连接到综框均为刚性连接,所以提综及回综均通过来自织机的动力来驱动综框上下运动,完成经纱开口、闭口。消极式多臂装置提综由多臂提综机构通过来自织机的动力来完成,而回综由单独的回综机构来完成,常见的回综机构通过若干组弹簧来执行完成。</span></p><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"><p style="max-inline-size: 100%; clear: both; min-height: 1em; cursor: text; text-indent: 2em; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;"><span style="max-inline-size: 100%; margin: 0px; padding: 0px; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;">&nbsp;&nbsp;&nbsp; (5)为保证多臂装置保持良好的运动状态及经久耐用,多臂装置应具有润滑部件,使多臂装置各运动副始终在润滑状态下平稳运动。</span></p></section><section class="_135editor" data-role="paragraph" id="autoparagraph" style="max-inline-size: 100%;
