Description

单针床经编机针床曲轴连杆机构 技术领域
本发明涉及单针床经编机针床传动机构，具体公开一种单针床经编机针床曲轴连杆机构。
背景技术
经编机是一种以化纤为原料，编织成服装面料、内衣料、泳装料、窗帘布、家纺用布、产业用布等的针织机械，由于经编机只用经线编织成布，因此具有生产工业流程短、生产效率高、织物品种多、投资费用低、能耗低等优点备受纺织界青睐。
现有的经编机的针床传动机构通常采用凸轮传动机构，由于凸轮旋转时惯性和离心力较大，影响机器运转速度，限制了机器生产效率的进一步的提高。
发明内容
本发明的目的在于：为解决以上问题提供一种能有效缩短针床连杆机构的动程，使其振动小、惯性小，使机器可以在更高的速度下运转，提高了生产效率的单针床经编机针床曲轴连杆机构。
本发明所采用的技术方案是这样的：
单针床经编机针床曲轴连杆机构，由连杆架、曲轴、若干连接杆以及销轴组成的连杆机构。
进一步地，在所述连杆架上开设有若干凹槽，所述曲轴固定于凹槽内并可自由转动。
进一步地，所述连接杆a一端与所述曲轴连接，另一端与销轴a连接并可 绕其转动。
进一步地，在所述连接杆a与所述曲轴连接处设置有夹紧装置，夹紧装置与所述曲轴的接触面为圆弧凹面，其上装有轴瓦。
进一步地，所述销轴a还与连接杆b连接，所述连接杆b分左右两部分，平行对称分布于所述销轴a两侧且可绕其转动。
进一步地，所述连接杆b的另一端与销轴b连接且可绕其转动。
进一步地，所述销轴a和销轴b两端分别装有连接杆c和连接杆d，且均可绕其转动。
进一步地，在所述连接杆c和连接杆d上均设置有若干凸出的圆柱a和圆柱b，圆柱上套有钢套，所述钢套装入连杆架的凹槽中。
进一步地，所述的销轴b的中间位置装有连接杆e，连接杆e可以绕销轴b转动，连接杆e上有紧固装置，可以调节连接杆e与销轴b的紧度，所述连接杆e的另一端连接成圈部分。
综上所述，由于采用上述技术方案，本发明的有益效果是：
1.这种机构的运动副均为转动副，相连接的杆(轴)是面接触，压强小，所以各部件接触的部位磨损较小，对成圈机件的运动规律影响较小，振动小，惯性小；
2.此结构传动平稳、精确，机器可以在更高的转速下运转，同时产生的噪音相对来说也较低，提高工作效率；
3.此种结构的各个零部件加工简便，比较容易得到较高的几何精度。

具体实施方式
下面结合附图对本发明作进一步地说明。
如图1所示，单针床经编机针床曲轴连杆机构，主要有由连杆架1、曲轴2、若干连接杆3、4、7、8、11、销轴6、10组成。
在所述连杆架1上开设有若干凹槽，所述曲轴2固定于凹槽内并可自由转动。
所述连接杆a3一端与所述曲轴2连接，另一端穿入销轴a6中间并可绕其转动。
在所述连接杆a3与所述曲轴2连接处设置有夹紧装置，夹紧装置与所述曲轴2的接触面为圆弧凹面，夹紧装置一分为二，每一部分内装有一个轴瓦，轴瓦上开有小孔，分开后的两部分套住曲轴2并通过两部分两侧的螺纹孔旋紧螺丝紧固，润滑系统将油打入小孔中，使轴瓦与曲轴2之间形成一层薄油膜，这样做的好处是可使曲轴2的转动更为顺畅，减小了曲轴2与轴瓦之间的摩擦，对曲轴2起到了很好的保护作用，减少了动力装置运行负荷以及各传动件相互作用力，节省电能的同时使机器的运行更加平稳、流畅。
所述销轴a6还与连接杆b7连接，所述连接杆b7分左右两部分，平行对称分布于所述销轴a6两侧且可绕其转动。
所述连接杆b7的另一端与销轴b10连接且可绕其转动。
