AI Technical Summary

Technical Problem

The existing toothed roller lacks a labyrinth seal structure between its end face and the mounting shaft, which makes it easy for dust and impurities to enter, leading to accelerated wear of components such as bearings, easy seal failure, frequent downtime for maintenance, poor operational stability, and decreased component reliability.

Method used

A labyrinth-type sealing structure for the end face of a toothed roller is designed, including a sealing mechanism and a fixing mechanism on the outer wall of the roller body. By using the combination of the sealing ring with the stator, rotor and connecting ring, dust and impurities are blocked from entering. Combined with the detachable tooth head design, the whole replacement is avoided after local wear, thus improving the sealing effect and maintenance convenience.

Benefits of technology

It effectively blocks dust and impurities, protects bearings and other components, extends service life, reduces downtime maintenance, ensures stable operation of the toothed roller, and improves component reliability and economy.
