Transmission method and transmission structure capable of preventing expansion ring from damaging transmission shaft of wire drawing machine

Abstract

The invention discloses a transmission method capable of preventing an expansion ring from damaging a transmission shaft of a wire drawing machine. The transmission method is characterized in that the expansion ring and a flat key are simultaneously arranged between a wire drawing wheel and the transmission shaft of the wire drawing machine. The invention also discloses a transmission structure for realizing the transmission method. The wire drawing wheel is fixed with the transmission shaft by the expansion ring so that the axial position of the wire drawing wheel on the transmission shaft can be better adjusted. When the fixed mode of the expansion ring is maintained, flat key connection is additionally arranged between the wire drawing wheel and a transmission wheel. The flat key can effectively prevent the wire drawing wheel from slipping on the transmission shaft, thereby preventing the expansion ring from damaging the transmission shaft. The transmission method and the transmission structure are simple but generate remarkable technical effect, and can improve the production efficiency and reduce the production cost.

Description

Technical field [0001] The invention relates to a wire drawing machine for enameled wire production, in particular to a method and structure for preventing damage to the drive shaft of the wire drawing machine. Background technique [0002] In the wire drawing machine of the wire factory, in order to facilitate the adjustment of the axial position of the drawing wheel on the drive shaft, an expansion ring is usually used to fix the drawing wheel on the drive shaft. The expansion ring includes an outer expansion ring and an inner expansion ring. The inner hole of the outer expansion ring is tapered. The outer diameter of the inner expansion ring is larger than the average inner hole diameter of the outer expansion ring. When the inner expansion ring is pressed into the outer expansion ring by the nut When, the outer expansion ring expands outward, squeezing the drive shaft and the drawing wheel tightly. However, the expansion ring connection method is used. In the process of use, ...

AI Technical Summary

Problems solved by technology

However, the connection method of the expansion ring is used. During the use process, the drawing wheel often has an impact rotation. When the drawing wheel has an impact rotation, the drawing wheel will slip on the transmission shaft, because the expansion ring is tightly squeezed on the drawing wheel. Between the drive shaft and the drive shaft, the expansion ring will often damage the drive shaft when slipping. After the drive shaft is damaged, it will no longer be usable. Only the drive shaft needs to be replaced.

Replacing the drive shaft is troublesome and increases production costs
