The articulated beam is structured by an oscillating bearing, a bearing chock and a rigid shaft; wherein the rigid shaft is connected with the bearing chock through the oscillating bearing.

铰接式横梁由关节轴承、轴承座和刚性轴构成，刚性轴与轴承座由关节轴承连接。

The central lines of the glide block and the piston rod can automatically overlapped by the auto adjustment of the oscillating bearing so as to make the running of the glide block stable and flexible.

在剪板工作中，通过关节轴承的自动调节，可自动完成滑块与活塞杆中心线重合，使滑块运行平稳灵活。
