Problems solved by technology

The traditional winding mechanism can only provide a constant resistance torque
The pay-off tension increases with the reduction of the wire in the wire shaft, the tension is the smallest when the reel is full, and the tension is the largest when the reel is empty, so the quality requirements of the winding cannot be guaranteed.

Abstract

The invention relates to a paying-off device, in particular to a constant-tension paying-off device. The constant-tension paying-off device aims to solve the problems that a traditional winding mechanism can only provide a constant resistance moment, the paying-off tension is increased along with reduction of wires in a wire shaft, the tension is smallest if a disc is full of the wires, the tension is largest if the disc is empty, and therefore the quality requirement of a winding cannot be met. The device comprises a wire wheel, a paying-off driving assembly and a damping mechanism, the paying-off driving assembly is installed on one side of the wire wheel, and the damping mechanism is installed on the other side of the wire wheel. The invention belongs to the field of electric power systems.

Description

technical field [0001] The invention relates to a pay-off device, in particular to a constant-tension pay-off device, which belongs to the field of electric power systems. Background technique [0002] During the manufacture of transformer windings, a constant winding tension must be applied to the wires throughout. In order to ensure that the surface of the winding is smooth and flat, the winding is tight and firm. However, the traditional winding mechanism can only provide a constant resistance torque. The pay-off tension is increasing with the reduction of the wire in the wire shaft, the tension is the smallest when the reel is full, and the tension is the largest when the reel is empty, so the quality requirements of the winding cannot be guaranteed. Contents of the invention [0003] The invention solves the problem that the traditional winding mechanism can only provide a constant resistance torque. The pay-off tension increases with the reduction of the wire in t...
