具体实施方式
下面结合附图和具体实施方式对本发明做进一步详细的说明。
实施例1
本实施例提供一种离心式润滑注塑机单缸射出机构，结合图1和图2所示，包括主体1，所述主体1的一端连接有驱动机构2，所述主体1内设有输出过渡轴3和轴承轴4，所述输出过渡轴3的一端与驱动机构2驱动连接，输出过渡轴3和轴承轴4之间通过传动套管5传动连接，还包括润滑油输送组件6，所述润滑油输送组件6一端贯通输出过渡轴3的端部与外界连通，另一端延伸至轴承轴4内，所述轴承轴4上还设有出油通道7，所述出油通道7一端与润滑油输送组件6相连通，另一端延伸至轴承轴4外表面与传动套管5内表面之间，转动轴承轴4可使润滑油输送组件6内的润滑油进入至出油通道7内。其中，驱动机构2可以包括减速机21。润滑油输送组件6中的润滑油通过出油通道7直接输送至轴承轴4外表面与传动套管5内表面之间，可减小润滑油所需用量，保证润滑效率。
本发明，使用时，润滑油通过润滑油输送组件6输送至轴承轴4内部，启动驱动机构2，减速机21驱动输出过渡轴3转动，输出过渡轴3带动传动套管5，传动套管5带动轴承轴4，轴承轴4转动过程中，轴承轴4内部的润滑油在离心力的作用下通过出油通道7排出至轴承轴4外表面与传动套管5内表面之间以实现润滑。故本发明设有润滑油输送组件6，外界润滑油可通过润滑油输送组件6将润滑油输送至轴承轴4和传动套管5之间，使得轴承轴4和传动套管5之间可实现润滑连接，从而降低轴承轴4和传动套管5之间的磨损程度，延长使 用寿命。
优选地，所述出油通道7沿轴承轴4的径向延伸，所述润滑油输送组件6轴心线即第二送油通道63的轴心线与轴承轴4的轴心线相重合。这样能使润滑油输送组件6内的润滑油受到最大的离心效果，防止润滑油回流。出油通道7沿轴承轴4的径向延伸可保证润滑油能较为顺利的通过出油通道7。
结合图2和图3所示，所述润滑油输送组件6包括设置在输出过渡轴3端部的进油组件61、设置在输出过渡轴3内的第一送油通道62和设置在轴承轴4内的第二送油通道63，所述进油组件61与第一送油通道62相连通，所述第二送油通道63与出油通道7相连通，润滑油输送组件6还包括第一润滑通管64，所述第一润滑通管64一端与第一送油通道62相连通，另一端与第二送油通道63相连通。
使用时，润滑油依次通过进油组件61、第一送油通道62和第一润滑通管64，并进入至第二送油通道63内。由于输出过渡轴3与轴承轴4并非直接连接，故在两者之间设置一根第一润滑通管64以保证润滑油的输送效率。
结合图2和图3所示，所述第一润滑通管64外表面通过第一密封件65与轴承轴4密封连接，所述第一润滑通管64外表面通过第二密封件66与输出过渡轴3密封连接，所述轴承轴4、输出过渡轴3、传动套管5、第一密封件65、第二密封件66和第一润滑通管64共同围合形成润滑空间67，所述润滑空间67与出油通道7相连通。即围合形成一个相对密闭的润滑空间67，从出油通道7排出的润滑油会进入至润滑空间67，润滑空间67相对密闭则可防止润滑油外泄，同时保证相同润滑油用量的前提下具有较长的有效润滑时间。
优选地，所述第二送油通道63连通有若干条出油通道7且出油通道7沿第二送油通道63的轴心线方向依次排布，所述出油通道7在轴承轴4端面的投影相互交错。这样可以保证润滑油通过出油通道7均匀排出至轴承轴4表面。
结合图2和图4所示，所述进油组件61包括与第一送油通道62相连通的第二润滑通管611，第二润滑通管611远离第一送油通道62的一端延伸至输出过渡轴3外部，所述输出过渡轴3内设有安装槽612，轴承613设置在安装槽612内，所述第二润滑通管611的外表面与轴承613的内圈相贴合。第二润滑通管611凸出至输出过渡轴3端部外侧，便于外界润滑油通过第二润滑通管611输入。
优选地，还包括设置在输出过渡轴3端部的盖板614，所述盖板614一端压设在输出过渡轴3上，另一端延伸至安装槽612内并压设在轴承613的外圈侧面。这样便于轴承613及第二润滑通管611的拆装。
如图5所示，所述轴承轴4表面凸出有若干条传动筋条8，相邻两个传动筋条8之间为润滑凹槽9，每个润滑凹槽9内设有至少一个润滑口10，所述润滑口10与出油通道7一一对应连通。
本发明的工作原理是：使用时，润滑油依次通过第二润滑通管611、第一送油通道62和第一润滑通管64，并进入至第二送油通道63内，启动驱动机构2，减速机21驱动输出过渡轴3转动，输出过渡轴3带动传动套管5，传动套管5带动轴承轴4，轴承轴4转动过程中，轴承轴4内部的润滑油在离心力的作用下通过出油通道7和润滑口10排出至轴承轴4外表面与传动套管5内表面之间以实现润滑，并最终外泄至润滑空间67内以实现对轴承轴4其他部位的润滑或二次润滑。故本发明设有润滑油输送组件6，外界润滑油可通过润滑油输送组件6将润滑油输送至轴承轴4和传动套管5之间，使得轴承轴4和传动套管5之间可实现润滑连接，从而降低轴承轴4和传动套管5之间的磨损程度，延长使用寿命。
实施例2
