AI Technical Summary

Technical Problem

In traditional clutch sealing mechanisms, the sealing ring is prone to movement under high-speed rotation and vibration, resulting in poor sealing performance.

Method used

The rotating shaft seal ring consists of a skeleton and a rubber sealing body, with a positioning bevel on the outside. Combined with an annular insert and positioning bolts, the positioning and clamping are achieved through the matching of the beveled conical surface to prevent movement.

Benefits of technology

It effectively prevents the sealing ring from shifting, improves sealing performance, ensures that the shaft sealing ring coincides with the axis, and improves the sealing effect.
