一种传动装置及使用该传动装置的开关设备
摘要：
本发明涉及一种传动装置及使用该传动装置的开关设备，传动装置包括主轴、传动杆和设置于主轴与传动杆之间的用于带动传动杆运动的传动部件，传动部件包括铰接连接于主轴上的摆臂和与摆臂铰接连接的换向传力杠杆，换向传力杠杆的一端与传动杆铰接连接，另一端铰接有导向件，传动装置还包括与导向件上下导向移动配合的导向结构，主轴在带动摆臂摆动时，换向传力杠杆会拉扯传动杆运动，由于设导向件与导向机构的配合关系使传动杆的受力方向改变不再沿换向传力杠杆的长度方向，并且换向传力杠杆对传动杆的作用力一部分被到导向件与导向机构承担，因此，在垂直于传动杆的运动方向上的分力变小了，即减小了传动杆上的摩擦力，减少了金属异物的产生。
摘要（英）：

The invention relates to a transmission device and switch equipment employing the same. The transmission device comprises a main shaft, a transmission rod, a transmission component and a guide structure, wherein the transmission component is arranged between the main shaft and the transmission rod and is used for driving the transmission rod to move; the transmission component comprises a swing arm and a reversing force transfer lever; the swing arm is hinged with the main shaft; the reversing force transfer lever is hinged with the swing arm; one end of the reversing force transfer lever is hinged with the transmission rod and the other end is hinged with a guide part; the guide structure and the guide part are guided up and down for movable cooperation; and when the main shaft drives the swing arm to swing, the reversing force transfer lever pulls the transmission rod to move. Due to the cooperative relationship between the guide part and the guide structure, the stress direction of the transmission rod does not change along the length direction of the reversing force transfer lever, and one part of acting force of the reversing force transfer lever on the transmission rod is undertook by the guide part and the guide structure. Therefore, the component force in the motion direction vertical to the transmission rod is reduced, namely the friction force on the transmission rod is reduced; and metal foreign matters are reduced.
