The structure shown in the figure : The governing body received direct or roller drying cylinder, as the main components of the rotation; After finishing the outside of the sphere, Bottom Cover and soak spherical carbon graphite seal ring joint seal reliable seal friction deputy, Sealing ring in the spherical shell of its annular space sliding, in addition to oil-free bearings and with the close cooperation of Shell, Rotating connector so that the free support, and therefore do not require a high level of accuracy installed; Spherical seal ring wear, Spring means of pressure at any time in advance to receive compensation, compensation for the shell slowly moved backward, accessible through the tube outside the inscription on the line to observe the seals wear; When steam, Oil flows through the media or other spherical sealing ring and oil-free bearings, the formation of thin liquid film, sealing and lubrication, thereby reducing friction and wear, extending the service life.

其结构如图所示：外管体直接接到辊子或烘筒上，为主要的旋转部件；经过精加工的外管本球面、底盖和浸泡碳石墨球面密封环共同组成密封可靠的动密封磨擦副，球面密封环在其壳体内的环形空间中滑动，加之无油轴承与壳体的密切配合，使旋转接头自由支撑，故对装机精度要求不高；球面密封环磨损后，借助于弹簧的预压力随时得到补偿，补偿时壳体缓缓向后移动，并可通过外管体上的刻线观察到密封件的磨损程度；当蒸汽、油或其它介质流经球面密封环和无油轴承时，形成一层很薄的液膜，提供密封和润滑，从而减轻了摩擦和磨损，延长了使用寿命。
