上述附图所示出的内容仅为举例和示意，并不严格按照比例予以绘制，也并未完整地绘制出具体使用环境下相关的全部部件或细节。本领域技术人员在了解本发明的原理和构思之后，将能想到在特定的使用环境下为具体实施本发明而需要加入的本领域公知的相关技术内容。
具体实施方式
在以下描述中可能使用的术语“第一”、“第二”等并不意欲限制任何序位，其目的仅仅在于区分各个独立的部件、零件、结构、元件等，并且这些独立的部件、零件、结构、元件可以相同、类似或者不同。同时，在以下描述中可能使用的关于方位的说明，比如“上”、“下”、“内”、“外”、“左”、“右”、“径向”、“轴向”等，除非具有明确说明，仅为了方便描述，而无欲对发明技术方案形成限定。
参见图1和图2，其中示出了根据本发明的一种驱动器的立体示意图。图中的驱动器包括电机、涡轮减速机构(仅示出其中的蜗杆轴)和连接两者的联轴器，其中联轴器连接电机的输出轴的一个端部80和涡轮减速机构的蜗杆轴的一个端部90。电机的动力通过联轴器传递至蜗杆轴，并进一步传递至与蜗杆轴啮合的涡轮，进而电机的高速旋转可以被输出为低速的平移，以适应具体的驱动要求。此外，联轴器在此还必须具有补偿功能和缓 冲功能，即能够补偿输出轴与蜗杆轴之间的位置失准以及缓减电机启动与停止以及运行过程中所产生的冲击和振动。对此，下文将予以特别的介绍和分析。
所述联轴器包括本体10，该本体由硬性材料制成，比如具有合适强度的塑料或者金属。本体10的内部设置有第一轴孔11和第二轴孔12，其中，电机的输出轴的端部80以固定连接的方式容纳于所述第一轴孔11内，以使得输出轴能与联轴器同步转动。所述蜗杆轴的端部90容纳于所述第二轴孔12，并且蜗杆轴的端部90可以在第二轴孔12内朝轴向、径向或者周向做小范围运动，以使联轴器实现上文所述的补偿功能和缓冲功能此做具体的说明。作为替换方式，也可以将电机的输出轴的端部80以能够实现位置补偿的方式安装于所述第一轴孔11内，而所述蜗杆轴的端部90固定安装于所述第二轴孔12内与联轴器同步转动。
以下参见图3，从中可见所述第二轴孔12的内壁面设置有由弹性材料构成的联接部30。联接部30通过二次成型一体地于本体10的第二轴孔12内，包括与所述第二轴孔12的内壁面连接的外周面和朝向所述第二轴件的端部90的内周面，其中，该联接部30的内周面围绕整个圆周包覆所述第二轴件的端部90。换句话说，联接部30至少在第二轴件的部分部段上以整体上大致呈套环的形式围绕第二轴件的端部90。
此外，联接部还包括不围绕第二轴件的端部90的部段。具体而言，如图3所示，第二轴孔12的内径被设置为大于第一轴孔11，并且本体10设置有沿轴向延伸并朝所述第二轴孔12敞开的开孔13，开孔12与第一轴孔11同心。相应地，所述联接部30从第二轴孔12延伸至所述开孔13内，从而联接部30分为两个部段，第一部段容纳于第二轴孔12内，第二部段容纳于开孔13内，其中，第一部段围绕整个第二轴件的端部90，而第二部段嵌入至开孔13内以将整个联接部30更好地固定至本体10内。
进一步地，所述开孔13为台阶孔，所述联接部30相应地成形有内凸缘40，该内凸缘40在轴向上突出至所述第二轴孔12内。为此，安装至第 二轴孔12内的蜗杆轴的端部90的端面抵接内凸缘40，以实现在轴向上的补偿和缓冲。
进一步地，所述第二轴孔12为台阶孔，所述联接部30相应地形成有外凸缘50。外凸缘50的设置有利于联接部30的注塑成型，并使得联轴器具有更好的补偿和缓冲功能。
以下将参照附图4-6进一步具体说明上述联轴器中的联接部30。首先，从图中可以看到，本体的第二轴孔12的内壁面上设置多个定位开槽，从而联接部30的材料可以嵌入至开槽内，以实现联接部在径向上能更好地成形于本体内壁面上。在图4中，本体内壁面上示出有6个圆形开槽和2个梯形开槽。当然，基于实际需要，所述开槽的形状和数量也可以与此不同。
此外，对应于蜗杆轴的端部90所包括的一对相对设置的弧形面91和一对相对设置的平坦面92，联接部30的外周面相应地设置有弧形面和平坦面。如图4所示，在电机停止工作从而联接部没有受到扭矩载荷的状态下，蜗杆轴的端部90所包括的一对相对设置的弧形面91和一对相对设置的平坦面92分别对准联接部的外周面上的弧形面和平坦面。
在内周面上，所述联接部30具有相对设置的一对第一径向缓冲突部33，该对第一缓冲突部33分别与联接部的相应的一个所述外弧面31相背，并且每个第一径向缓冲突部33相应地抵接第二轴件的端部90的一个所述弧形面91。进一步地，所述联接部30的内周面进一步地具有相对设置的一对第二径向缓冲突部34，该对第二径向缓冲突部34分别与联接部30的相应的一个平坦面相背，并且相应地抵接第二轴件的端部90的一个平坦面92。
每个所述第二径向缓冲突部34在联接部的内周面内沿轴向延伸，其截面整体呈梯形，包括与所述端部90的平坦面92相接的顶面和与所述第二轴件的端部90的所述平坦面92以间隙相隔的侧面35，所述侧面在所述联轴器传递动力时将与所述平坦面92抵接并受力变形。此外，所述第二径向缓冲突部34设置有垂直第二轴件的端部的所述平坦面94的凹槽36，该凹 槽36将所述第二径向缓冲突部34分隔成多个部分。凹槽的设置允许所述第二径向缓冲突部34在传递扭矩时具有更大的变形量，从而具有更好的补偿和缓冲效果。
从图4中可见，在电机停止工作从而联接部30没有扭矩载荷的状态下，蜗杆轴的端部90的一对弧形面91和一对平坦面92分别抵接所述联接部上的第一径向缓冲部33和第二径向缓冲部34，从而蜗杆轴的端部90在联轴器内的径向位置可能存在的失准可以得以补偿。同时，蜗杆轴的端部90可能存在的轴向位置失准可以通过联接部30上的内凸缘40而得以补偿，参见图3。
进一步参见图5，在电机以正转工作时，其输出轴的转动通过端部80(见图3)传递至联轴器本体10，联接部30随本体10一起转动。联接部30的第二径向缓冲部的侧面35首先转动至与蜗杆轴的平坦面92相抵并受力变形，在此过程中，第二径向缓冲部34对平坦面92的作用力逐渐增大，蜗杆轴的转速也随着逐渐增加，直至第二径向缓冲部34达到最大变形，蜗杆轴与联轴器以及输出轴同步转动。在这个过程中，联接部经历了侧面35与蜗杆轴的端部92从间隔至接触、从部分传动至同步传动的过程，从而实现所需的缓冲效果。同样，在电机以反转工作时，联接部同样经历侧面35与蜗杆轴从间隔至接触、从部分传动至同步传动过程，以实现所需的缓冲效果，如图6所示。
上文描述的仅仅是有关本发明的精神和原理的示例性实施方式。本领域技术人员可以明白，在不背离所述精神和原理的前提下，可以对所描述的示例做出各种变化，这些变化及其各种等同方式均被本发明人所预想到，并落入由本发明的权利要求所限定的范围内。
