AI Technical Summary

Technical Problem

The existing mechanical shaft structure of the morin khuur lacks anti-worm gear movement function, which causes the worm gear to wear out more due to inertial movement, affecting its service life.

Method used

A novel mechanical shaft structure for the morin khuur (horsehead fiddle) is designed. The positioning plate is positioned by the cooperation between the anti-slip plate and the shaft housing. The positioning plate provides rigid constraint on the worm gear to prevent the worm gear from moving due to inertia during rotation and to avoid abnormal contact or frictional interference with adjacent components.

Benefits of technology

It effectively prevents worm gear movement, improves the stability and durability of the transmission system, and extends the service life of components.

Abstract

The utility model relates to wig disinfection technical field, especially new morinhu mechanical shaft structure, including shaft body shell, anti -run -out board and limit piece, the inside fixed connection of shaft body shell has anti -run -out board, the inside fixed connection of shaft body shell has the limit board, the inside of shaft body shell is provided with worm, the outside of worm and anti -run -out board rotation is connected, the outside of worm and limit board rotation is connected, the top fixed connection of worm has limit piece, be provided with drive mechanism on worm, drive mechanism is used for controlling the rotary motion of worm, and the inside of shaft body shell is provided with linkage mechanism, the utility model discloses the installation position of limit piece is positioned restraint through the cooperation and connection between anti -run -out board and shaft body shell, since limit piece has been pre -defined in fixed position, thereby forms rigid restraint to the axial movement range of worm, this restraint effect can avoid worm and adjacent structural component abnormal contact or friction interference, has realized the function of preventing worm to move.
