Description

一种新型传动结构 技术领域
本发明涉及传动装置技术领域，尤其是一种新型传动结构。
 背景技术
对于两个轴距较远的转动体进行动力同步传动时，通常采用的方法是使用链条传动或同步带传动，结构简单，操作方便，但是成本高、噪音大，且在具有一定传送扭力和运动速度较慢的工作环境中应用效果差。
 技术问题
本申请人针对上述现有生产技术中的缺点，提供一种结构合理的新型传动结构，从而解决解决链条或同步带传动噪音大、成本高的技术问题。
 技术解决方案
本发明所采用的技术方案如下：
一种新型传动结构，包括传动轮组件，所述传动轮组件包括间隔设置的至少两个轮件，还包括传动绳，所述传动绳上设有多个传动块，传动绳依次绕过所述轮件，形成开环结构或闭环结构。
作为上述技术方案的进一步改进：
传动绳采用金属材质或非金属材质，传动块采用金属材质或非金属材质；传动绳的结构为：具有一条绳本体，其上设有多个所述传动块；或者具有至少两条间隔设置的绳本体，并通过传动块将所述至少两条间隔设置的绳本体连接成一体。
闭环结构的传动轮组件为：包括第一传动轮，与其间隔设有第二传动轮，传动绳依次绕过第一传动轮和第二传动轮形成闭环；传动块分布在整段传动绳上，且第二传动轮采用链轮式结构；或者传动块分布在传动绳上与第一传动轮相配合的一段上，且第二传动轮采用绳轮式结构。
闭环结构的传动轮组件为：包括在平面内间隔设置的四个第一传动轮，传动绳依次绕过四个第一传动轮形成闭环，四个第一传动轮由驱动机构驱动旋转。
开环结构的传动轮组件为：包括间隔设置的两个第一传动轮，传动绳依次绕过两个第一传动轮，并在两端分别形成自由端，所述自由端上连接有重锤。
第一传动轮采用链轮式结构，在第一传动轮的圆周侧面上开有多个沿轴向延伸的、与所述传动块啮合传动的凹槽，相邻两凹槽的间距与相邻两传动块的间距相等。
每个凹槽的顶部边缘或底部边缘沿径向延伸有挡板。
传动绳上固定安装有滑块离合组件。
第一传动轮、第二传动轮分别通过轮座安装在导轨的两端，所述滑块离合组件滑动安装在导轨上，第一传动轮连接有驱动机构。
第一传动轮或第二传动轮一旁安装有第一张紧机构，其结构为：包括支架，其上安装有固定片，固定片中部开有卡齿孔；还包括张紧齿条，其一端伸出所述卡齿孔，并通过锯齿与卡齿孔卡接，另一端固定在第一传动轮或第二传动轮的轮座上；张紧齿条与一根张紧弹簧的一端连接，张紧弹簧的另一端固定在位于卡齿孔一侧的固定片或支架上。
支架成槽形结构，槽形结构内一体式设有固定片；槽形结构的两侧面上分别设有与导轨配合的耳钩；张紧齿条与第二传动轮或第一传动轮的轮座固定连接的一端沿宽度方向延伸有连接端，连接端上通过通孔与所述张紧弹簧的一端连接。
采用非金属材质的传动绳上固定安装有与滑块离合组件连接的第二张紧机构，其结构为：包括固定器，在预拉紧的状态下，固定器固定在传动绳松端的一侧，固定器与一根收紧带的一端连接，收紧带的另一端与所述滑块离合组件的一端连接。
 有益效果
本发明结构紧凑、合理，传动噪音小，适用于具有扭力同步传动，如电动门、窗的驱动，工业设备，家用电器以及家居产品等行领域的传动工作场景，特别是提高了具有一定传送扭力和运动速度较慢的工作环境中的应用效果，并显著降低了成本。
同时，本发明还具有如下优点：
1、传动绳上设置的传动块与第一传动轮上的凹槽啮合传动，确保传动过程中传动绳不打滑，且降低了噪音；挡板将传动绳限制在轮中部的圆周面上，防止其脱轨，提高运行的稳定性。
2、传动绳和传动块均可采用金属或非金属材质，材料选择范围广，成本低；传动绳和传动块有两种不同的设置方式：传动块分布在整段传动绳上，同时第二传动轮也采用链轮式结构，这种结构可以给第二传动轮同步传动动力，且整段带传动块的传动绳加工工艺简单，效率高；或者传动块分布在与第一传动轮配合的一段上，而另一段仍采用圆滑的传动绳，同时第二传动轮则采用绳轮式结构，该结构更能有效降低成本。
3、张紧齿条、张紧弹簧组成的第一张紧机构，可以在采用非金属材质的传动绳严重松弛时，通过张紧齿条向固定片的卡齿孔内自适应的进扣，达到自动张进的目的，确保动力机构始终有合适的张紧力，防止伸缩率大的化纤绳因为时间长使用造成的松弛。
4、收紧带、固定器组成的第二张紧机构，在预拉紧的状态下，两端固定在传动绳松端的一段长度上，当松端松弛时，收紧带可以收缩，以保证传动绳始终有一定的张紧力以避免打滑或错槽。
5、本发明的传动结构可以是开环或闭环结构，开环结构的重锤起张紧作用，利用往复运动的特点，广泛适用于物体的纵向起吊或横向传送；闭环结构的传动轮组件可以为两个及以上的轮件，驱动多个轮件同步运动时，可应用于控制工业设备内各机构的同步工作。

下面结合附图，说明本发明的具体实施方式。
如图1、图9和图10所示，本实施例的新型传动结构，包括传动轮组件，传动轮组件包括间隔设置的至少两个轮件，还包括传动绳2，传动绳2上设有多个传动块3，传动绳2依次绕过轮件，形成开环结构或闭环结构。
如图8所示，传动绳2采用金属材质或非金属材质，传动块3采用金属材质或非金属材质；传动绳2的结构为：具有一条绳本体21，其上设有多个传动块3；或者具有至少两条间隔设置的绳本体21，并通过传动块3将至少两条间隔设置的绳本体21连接成一体；绳本体21为长条的圆柱形或椭圆柱形结构，传动块3采用珠状或柱状结构。
如图2-图4所示，闭环结构的传动轮组件为：包括第一传动轮1，与其间隔设有第二传动轮4，传动绳2依次绕过第一传动轮1和第二传动轮4形成闭环；传动块3分布在整段传动绳2上，且第二传动轮4采用链轮式结构；或者传动块3分布在传动绳2上与第一传动轮1相配合的一段上，且第二传动轮4采用绳轮式结构。
如图9所示，闭环结构的传动轮组件为：包括在平面内间隔设置的四个第一传动轮1，传动绳2依次绕过四个第一传动轮1形成闭环，四个第一传动轮1由驱动机构驱动旋转。
如图10所示，开环结构的传动轮组件为：包括间隔设置的两个第一传动轮1，传动绳2依次绕过两个第一传动轮1，并在两端分别形成自由端，自由端上连接有重锤9。
如图3所示，第一传动轮1采用链轮式结构，在第一传动轮1的圆周侧面上开有多个沿轴向延伸的、与传动块3啮合传动的凹槽11，相邻两凹槽11的间距与相邻两传动块3的间距相等。
每个凹槽11的顶部边缘或底部边缘沿径向延伸有挡板12。
如图4和图5所示，传动绳2上固定安装有滑块离合组件5。
如图7所示，第一传动轮1、第二传动轮4分别通过轮座安装在导轨6的两端，滑块离合组件5滑动安装在导轨6上，第一传动轮1连接有驱动机构。
如图6所示，第一传动轮1或第二传动轮4一旁安装有第一张紧机构，其结构为：包括支架14，其上安装有固定片19，固定片19中部开有卡齿孔191；还包括张紧齿条18，其一端伸出卡齿孔191，并通过锯齿与卡齿孔191卡接，另一端固定在第一传动轮1或第二传动轮4的轮座上；张紧齿条18与一根张紧弹簧13的一端连接，张紧弹簧13的另一端固定在位于卡齿孔191一侧的固定片19或支架14上。
支架14成槽形结构，槽形结构内一体式设有固定片19；槽形结构的两侧面上分别设有与导轨6配合的耳钩141；张紧齿条18与第二传动轮4或第一传动轮1的轮座固定连接的一端沿宽度方向延伸有连接端181，连接端181上通过通孔与张紧弹簧13的一端连接。
如图1和图2所示，采用非金属材质的传动绳2上固定安装有与滑块离合组件5连接的第二张紧机构，其结构为：包括固定器16，在预拉紧的状态下，固定器16固定在传动绳2松端的一侧，固定器16与一根收紧带17的一端连接，收紧带17的另一端与滑块离合组件5的一端连接。
本实施例的传动块3和第一传动轮1上的凹槽11配合，广泛适用于各种低速传动场合；传动绳2采用金属或非金属材质，如钢丝绳或尼龙绳等，传动块3可采用金属或非金属，如锌合金、铝合金或者塑料材质中的聚甲醛、聚碳酸酯、尼龙等；第一传动轮1可以是金属材质如钢、铝合金、锌合金等，也可以是非金属如聚甲醛、尼龙等；第二传动轮4根据需要可以是和主动链轮1采用一样的防滑结构，也可以是普通张紧轮结构，第二传动轮4材质和第一传动轮1材质一样。
具有第一传动轮1和第二传动轮4的闭环结构的在实施过程中：第一传动轮1连接驱动装置；第一传动轮1、第二传动轮4的轮座之间安装导轨6，滑块离合组件5与门窗连接件连接，随传动绳2沿导轨6运动，实现门窗的开闭。
传动绳9若采用伸缩率大的化纤绳，可能因为长时间使用而松弛。由张紧齿条18、张紧弹簧13和支架14构成的第一张紧机构，可以在传动绳9严重松弛时，进行自适应的张紧：张紧齿条18的一端与卡齿孔191配合，当传动绳9严重松弛时，张紧齿条18的齿向卡齿孔191中进一步自适应的进扣，确保动力带始终有合适的张紧力。张紧弹簧13的一端和张紧齿条18的一端构成杠杆结构，保证张紧齿条18卡紧在卡齿孔191的一侧，提高了稳定性；
采用非金属材质传动绳2，随着传动张力的变化会有一定的长度变化，为了防止传动张力大时，松边过度松弛，可以选择增加一个冗余量大的张紧结构：收紧带17和固定器16组成的第二张紧机构，在预拉紧的状态下，固定器16两端固定在传动绳9松端的一段上，当传动绳9的松端松弛时，收紧带17可以收缩，以保证传动绳9始终有一定的张紧力以避免打滑或错槽。
如图1-图4和图5所示，根据需要第二传动轮4一旁可采用普通的张紧装置或采用本实施例的第一张紧机构。
如图9和图10所示，具有两个第一传动轮4的开环结构可通过重锤9起张紧作用，利用往复运动的特点，广泛适用于物体的纵向起吊或横向传送；具有四个第一传动轮1的闭环结构的传动轮组件，还可以为三个、五个等多个轮件，驱动多个轮件同步运动时，可应用于控制工业设备内各机构的同步工作。
