AI Technical Summary
When the high-speed double twister manufactures thick steel cords, the traction shaft is bent because it cannot withstand high tension, which eventually leads to fatigue and fracture.
A mechanism including a traction shaft, driven wheel pin shaft, multi-slot traction wheel and multi-slot driven wheel is designed, and the traction shaft and driven wheel pin shaft are connected to the connecting bridge through the connecting bridge. The large tension of the winding is borne by the connecting bridge, thereby preventing the traction shaft from being deformed.
It effectively prevents the traction shaft from deforming during high tension, and improves the service life and production efficiency of the equipment.

Abstract
Description
Technical Field
[0001] The utility model relates to a mechanism on a high-speed double-twisting machine, and specifically discloses a mechanism for preventing a traction shaft from being deformed under high tension. Background Art
[0002] At present, the installation structure of the multi-groove traction wheel and the multi-groove driven wheel on the conventional high-speed double twisting machine is as follows: Figure 1 As shown, the traction shaft 1 is rotatably mounted on the reduction box body, the driven wheel pin 2 is fixedly mounted on the reduction box body through the external thread at its inner end, the traction shaft 1 and the multi-groove traction wheel 3 are connected and fixed by a tension sleeve to rotate together, and the multi-groove driven wheel 4 is rotatably mounted on the driven wheel pin 2. When in use, the steel cord 9 winds from the first groove on the multi-groove traction wheel 3 to the multi-groove driven wheel 4, and then winds back and forth until it winds to the last groove of the multi-groove traction wheel 3. This structure can meet the manufacturing of conventional fine-gauge steel cords, but when manufacturing thick-gauge steel cords, the traction shaft 1 will bend because it cannot withstand such a large winding tension, which will eventually lead to fatigue fracture of the traction shaft 1.
