AI Technical Summary

Technical Problem

The existing sealing components do not rotate with the shaft. After a long time, there will be a gap between the seal and the shaft, which will easily wear.

Method used

A sealing structure for the end cover of the shaft of the dragon conveyor is designed, including a shaft body, a front cover, a rear cover and a fixing mechanism. The front cover is slidably connected to the shaft body and the rear cover is slidably connected to the shaft body. The fixing mechanism includes a fixing ring, a first sealing ring, a second sealing ring and a sealing assembly. The sealing ring and the sealing assembly rotate with the shaft body to reduce friction.

Benefits of technology

The seal is realized when the shaft body rotates, reducing friction and wear, and extending the service life of the seal.
