结合附图1-6，本实施例的传动结构，包括转轴1和传动体2，所述转轴1一端设有限位轨道11，转轴1另一端用于连接驱动机构5，所述传动体2一端与限位轨道11活动配合，以使转轴1转动时，传动体2在限位轨道11的限位下沿转轴1的轴线做往复运动，传动体2另一端用于连接需要直线往复做功的设备。驱动机构5驱动转轴1转动，转轴1转动时，传动 体2在限位轨道11的限位下沿转轴1的轴线做往复运动，从而使与传动体2连接的设备沿直线往复做功，有利于减少偏向力，降低功率损耗，提高传动效率。本实施例的传动结构可应用于多个需要直线往复做功的设备，例如压缩机、清洗机、振动器、泥浆泵、喷漆设备等等。
实施例2
结合附图1-6，本实施例的传动结构，与实施例1的技术方案相比，可改进如下：所述传动体2一端对称设有传动件21，所述限位轨道11沿转轴1的周向延伸，且限位轨道11沿转轴1的轴向往复延伸设置，所述传动件21与限位轨道11活动配合。当转轴1转动时，对称设置使传动件21相互抵消偏向力，从而带动传动体2沿转轴1的轴线做往复运动。传动件21可以有多对，与传动件21活动配合的限位轨道11可以有多条，当限位轨道11有多条时，多条限位轨道11分为两组，每一组包括多条限位轨道11；一组所述限位轨道11设置于所述往复轴的一端，该组所述限位轨道11中，一条所述限位轨道11围绕所述转轴1的轴线旋转预设角度后，与另一条限位轨道11相重合；对应的多个所述传动件21的中心连线所在平面与所述转轴1的轴线相垂直。另一组所述限位轨道11设置于所述转的另一端，该组所述限位轨道11中，多个所述限位轨道11平行间隔分布，对应的多个所述传动件21的中心连线与所述转轴1的轴线平行。

实施例7
结合附图1-6，本实施例的传动结构，与实施例1-6任一项技术方案相比，可改进如下：结合附图1-6，本实施例的传动连接机构，包括机体3、活塞4和实施例1～5任一项技术方案所述的传动结构，所述第一导向件71设置在机体3上，所述活塞4一端设置在机体3内部，活塞4另一端与传动体2连接，以使传动体2带动活塞4在机体3内部做直线往复运动。直线往复传动结构还包括传动壳8。转轴1、传动体2、传动件21以及紧固件6均设置于传动壳8内，传动壳8通过导轨与机体3连接。如此，传动壳8与传动连接机构形成一体式结构，有利于提高结构紧凑性和传递效率。
实施例8

驱动机构5驱动转轴1转动，转轴1转动时，传动体2在限位轨道11的限位下沿转轴1的轴线做往复运动，从而使与传动体2连接的活塞4沿直线往复做功，所述第一气道32设有第一阀门和第二阀门，所述第二气道设有第三阀门和第四阀门，当活塞4向着靠近转轴1的方向运动时，活塞4将空气从所述第一气道32的第一阀门吸入空腔31内，同时并将空腔31内的空气从所述第二气道33的第三阀门排出，当活塞4向着远离转轴1的方向运动时，活塞4将从所述第一气道32的第二阀门吸入空腔31内，同时并将空腔31内的空气从所述第二气道33的第四阀门排出。活塞4往复过程中没有偏向力，并来回双向做功，降低功率损耗，提高传动效率，实现双向做功，同时可实现多个机体3同时沿转轴1的轴线往复做功，增加空压机的工作效率。本发明对机体3的形状不做限定，机体3可以根据工艺的需要设计为用户所需的具体形状。
