Description

一种织机平旋引纬传动机构 技术领域
本发明涉及一种纺织机械传动机构，具体说是剑杆织机传动剑头剑带往复运动的织机平旋引纬传动机构。
背景技术
高速剑杆采用引纬传动机构固定和筘座分离共轭凸轮打纬的结构，因运动件少惯性小便于高速运转。目前引纬传动机构典型的有三种：
第一种是采用共轭凸轮、转子、摆轴、联杆、齿臂、传动齿轮等实现引纬，其缺点是参与往复运动的件多，累积间隙误差大，高速交接时自由动程大，不易织机高速运转；第二种是采用空中摇架的方式实现引纬，其参与往复运动件虽然少一些，但其摇架摆动零件重量较重且加工要求非常高，内应力大，生产成本高，不便于批量生产；第三种是采用螺杆形式传动引纬，虽然传动件也不多，但其螺杆的变螺距加工，加工要求非常高，生产成本高，且驱动螺杆的滑块作力于螺杆是采用的滑动摩擦，阻力较大，使用成本高，不能大量普及。
发明内容
针对上述存在的问题，本发明提供了一种传动结构简单、稳定、能充分满足织机织造时剑带剑头在织口内停顿时间短、在织口外停顿时间长的高速高效引纬传动机构。
本发明采用的技术方案是：一种织机平旋引纬传动机构，其特征在于包括机架、主动轴或主动盘、一级偏芯轴、驱动滚轮或驱动块、滑槽、被动轴或被动盘、主动轴轴承或主动盘轴承、一级偏芯轴轴承、被动轴轴承或被动盘轴承、二级偏芯轴、引纬联杆、引纬联杆轴承、联接支轴、支点轴承、往复齿臂、齿臂轴承、齿臂旋转支轴、输出齿轮轴、输出齿轮轴轴承和传剑轮，主动轴或主动盘和被动轴或被动盘圆心线平行但不在同一圆心且各自可旋转设于机架上，主动轴轴端或主动盘端面上固定设有随其旋转、圆心线与其圆心线平行但不同心的一级偏芯轴，一级偏芯轴上经一级偏芯轴轴承套接有驱动滚轮或驱动滑块，驱动滚轮或驱动滑块伸入被动轴轴端或被动盘端面上所设的滑槽内呈作力于滑槽侧壁状态，一级偏芯轴圆心线与主动轴或主动盘圆心线的距离大于被动轴或被动盘圆心线与主动轴或主动盘圆心线的距离；在主动轴或主动盘旋转一周的过程中会通过一级 偏芯轴、驱动滚轮或驱动滑块、滑槽带动被动轴或被动盘相对于主动轴或主动盘作出一个速度比快慢变化的360°旋转，当一级偏芯轴的圆心线旋转到离被动轴或被动盘的圆心线距离最近时，被动轴或被动盘相对于主动轴或主动盘的旋转运动速比最快，反之则最慢；被动轴或被动盘上另固定设有平行于其圆心线的二级偏芯轴，二级偏芯轴经联杆轴承套接于引纬联杆一端，引纬联杆另一端经支点轴承套接于联接支轴上，联接支轴固定锁紧于往复齿臂非圆心上，往复齿臂经齿臂轴承套接于齿臂旋转支轴上，齿臂旋转支轴固定安装于机架上呈由被动轴或被动盘360°旋转经二级偏芯轴带动齿臂绕齿臂旋转支轴圆心往复运动状态；往复齿臂设有以齿臂旋转支轴为圆心、圆形齿面与输出齿轮轴的齿轮啮合，输出齿轮轴由输出齿轮轴轴承支撑在机架上旋转，传剑轮固定联接于输出齿轮轴上并驱动剑带剑头作往复运动。
进一步地，还包括二级偏芯轴稳定机构，所述二级偏芯轴稳定机构包括稳定联杆、稳定支轴、稳定支轴轴承和机架，稳定联杆一端固定联接二级偏芯轴，另一端固定联接稳定支轴，稳定支轴经稳定支轴轴承支撑在机架上旋转，稳定支轴的圆心线与被动轴或被动盘的圆心线同心，且两者同步旋转。
进一步地，所述主动轴或主动盘是织机旋转的主轴本体或是经齿轮与织机主轴联接随其旋转的轴或盘；所述主动轴或盘和被动轴或被动盘各自可以是一根轴或圆盘或轴和圆盘的结合件或轴和杠杆的结合件。
进一步地，所述一级偏芯轴和滑槽可各自分别设于主动轴或主动盘上和被动轴或被动盘上，也可各自分别设于被动轴或被动盘和主动轴或主动盘上；一级偏芯轴轴承和驱动滚轮可合二为一。
进一步地，所述往复齿臂可以经齿臂轴承在齿臂旋转支轴上旋转，也可以固定联接齿臂旋转支轴经轴承在机架上旋转；所述往复齿臂与输出齿轮轴之间可以根据传动需要采用一级或多级齿轮变速传动输出。
再进一步地，所述滑槽的槽宽中心线通过被动轴或被动盘端面的圆心。
本发明机构传动时，主动轴或主动盘旋转，一级偏芯轴绕主动轴或主动盘圆心线旋转，由于一级偏心轴上的驱动滚轮或驱动滑块限位于被动轮或被动盘的滑槽内，一级偏芯轴旋转经驱动滚轮或驱动滑块驱动被动轴或被动盘被动旋转，在一级偏芯轴的圆心线旋转到离被动轴或被动盘的圆心线距离最近时，被动轴或被 动盘相对于主动轴或主动盘的旋转运动速比最快，此时剑头在织口内交接位置，在一级偏芯轴的圆心线旋转到离被动轴或被动盘的圆心线距离最远时，被动轴或被动盘相对于主动轴或主动盘的旋转运动速比最慢，此时剑头退至织口外最远处，因此在一级偏芯轴360°旋转过程中发生速度比快慢变化；由此通过二级偏芯轴经引纬联杆带动往复齿臂绕齿臂旋转支轴作速度比快慢变化的往复旋转，往复齿臂传动输出齿轮轴的齿轮传动传剑轮并由传剑轮驱动剑带剑头作速度比快慢变化的往复运动。
该机构作360°旋转速度比快慢变化的往复运动，其快慢变化的时间和在360°角度分布设计满足剑带剑头送纬织造要求，其交接传动柔和、冲击力小，有效的优化了剑带剑头的运动轨迹，且零件加工简单，成本低、惯性小、易维修，节约了生产成本，机构中参与往复运动的零件少，杜绝了剑头剑带受传动累积间隙误差超程的现象，更利于织机高速运转，提高了织机运转效率。
