    • An overload coupling for two members, one rotating the other about a common axis, includes one or more frangible pin-like elements. Upon overload, the pin fractures and relative rotation between the members takes place. A spring or springs automatically urges one of the elements, mounted on one of the members, into engagement with an abutment on the other member to re-establish a rigid connection. The pin or pins can be in holders that extend radially or parallel to the common axis and each pin can be weakened in several areas and re-used. Also, a number of pins can be housed in a cassette that is connected to one coupling member by a release connection. Upon overload, in one embodiment, the spring or springs are mounted to urge the pin or pins only upon a reduction in the rotational speed of the coupling, when centrifugal force is overcome. The fragment broken off by the abutments in a channel for ejecting the fragment so that another pin or, at least an unbroken portion of the same pin, can re-establish connection as before.
    • 两个构件(一个围绕公共轴线旋转的构件)的过载联轴器包括一个或多个易碎的销状元件。 在过载时,销钉断裂,并且构件之间的相对旋转发生。 弹簧或弹簧自动地促使安装在其中一个构件上的元件之一与另一个构件上的邻接件接合以重新建立刚性连接。 销或销可以在径向或平行于公共轴线的支架中,并且每个销可以在几个区域中被削弱并重新使用。 此外,多个销可以容纳在通过释放连接连接到一个联接构件的盒中。 在过载时,在一个实施例中,当克服离心力时,弹簧或弹簧被安装成仅在减小联接器的转速时推动销或销。 通过用于弹出片段的通道中的基台断裂的片段使得另一个引脚或相同引脚的至少一个未断开的部分可以像以前一样重新建立连接。

    • An overload coupling includes an automatically positioned frangible portion to replace a just fractured frangible portion. A first coupling member caused to rotate by the power take-off of a tractor, or the like, has a rotary advancing spring connected thereto which can be hand wound to bias a removable magazine for the frangible element carried by a housing mounted on the first coupling member so as to be rotated by the advancing spring. A second coupling member is journalled on the first coupling member and drivingly connects to an agricultural implement or the like. It further connects through the frangible element to the first coupling member. The first coupling member defines a guide for the end of the frangible element, a portion of which is received in a slot or opening in the second coupling member. When the portion of the frangible element in such opening fractures due to an overload transmitted from the implement to the second coupling member, the advancing spring causes a further frangible portion to be introduced into the opening after, however, the first coupling member has its speed sufficiently reduced to permit such introduction. In one embodiment, the frangible element is a steel tape; in another it is a plurality of radially extending shear pins each adapted to be twice fractured. A cam on the interior of a ring advanced by the spring causes a non-fractured (or once fractured) shear pin to be moved into the opening therefor following each fracture of the preceding pin in the opening. The shear pins are disposed in single or double rows in an arc of about 160.degree. in the first coupling member. In another embodiment, the shear pins extend parallel to the axis of rotation of the coupling members.
    • 过载耦合包括自动定位的易碎部分以替代刚刚断裂的易碎部分。 通过拖拉机等的动力输出引起的旋转的第一联接构件具有连接到其上的旋转进给弹簧,该旋转进给弹簧可以手动地卷绕以偏置可移动的弹匣,用于由安装在第一个 联接构件,以便由前进弹簧旋转。 第二联接构件被轴颈安装在第一联接构件上并且驱动地连接到农用工具等。 它还通过易碎元件连接到第一联接构件。 第一联接构件限定用于易碎元件的端部的引导件,其一部分被容纳在第二联接构件中的狭槽或开口中。 当这种开口中的易碎元件的部分由于从工具传递到第二联接构件的过载而断裂时,推进的弹簧使另外的易碎部分被引入到开口中,然而,第一联接构件具有其速度 足够减少以允许这种引入。 在一个实施例中,易碎元件是钢带; 在另一个中,它是多个径向延伸的剪切销,每个适于两次断裂。 由弹簧推进的环的内部的凸轮使得未断裂的(或一次断裂的)剪切销被移动到开口中,用于在开口中的前一个销的每个断裂之后。 剪切销在第一联接构件中以大约160度的弧形排列成单列或双列。 在另一个实施例中,剪切销平行于联接构件的旋转轴线延伸。
