Description

一种小型万向联轴节
技术领域
本发明属于机械领域，具体涉及的是小型联轴节。
背景技术
万向联轴节有好几种，有十字联轴节等，但如果轴径比较小，如3毫米，特别是，一个比较大的轴和一个比较小的轴联接，这些联轴节显得大材小用，加工也比较复杂。
发明内容
本发明要解决的技术问题是，对小型轴、特别是直径相差较大的轴的联轴器的改善。
为了达到上述目的，本发明是这样一种小型万向联轴节，它包括大轴，小轴、传动体、弹簧，其特征是，大轴有轴孔，套在小轴上，之间有间隙，传动体通过大轴上的径向圆柱孔，被弹簧压在小轴的园锥孔上，小轴上圆锥孔接近中心。依靠弹簧的压力，使传动体保持压紧，传递扭力。
作为优先方案，所述的传动体可按圆周三等分分布，使得定心效果较好。传递扭力随着传动体数量的增加而增大。
作为优先方案，所述的传动体按圆周两等分对称分布，使得加工方便，成本最低。同时基本保证对中要求，同其他对称分布的偶数传动体一样，传递扭力成为力偶，效果较好。
作为优先方案，所述的传动体是球头钢柱，大多数小轴轴颈都需要钻孔达到一定深度，使得小轴圆锥孔距离接近中心，所以都需要球头钢柱。
作为优先，当轴径较小时，锥孔深度较小，所述的传动体就可以是钢珠。使得结构更为简单。
上述方案，具有如下优点：
结构简单，成本低廉。
附图说明
图1是结构示意图。
图2为扭力传递示意图。
件1是大轴，件2是弹簧，件3是传动体，件4是小轴。
具体实施方式
下面结合附图对本发明作进一步描述：
大轴件1，直径为d＝7，有一个内孔为2.5的轴孔，其上，通过中心钻了一个d＝1.3的径向通孔，套在小轴直径为d＝2的件4上，在小轴件4上通过中心，钻了对称2个d＝1.3深度仅为0.8的120度的锥孔，对准孔位，加入黄油后，每边压入2个d＝1.3的钢珠，大轴外径弹簧槽上卡上弹簧。小轴转动时，通过钢珠，带动大轴转动，允许两轴有一定的轴夹角；当扭力超过一定值时，打滑，具有过载保护，同时，也能承受一定的轴向力。
