Description

Novel variable-frequency cable drum

Technical Field

The utility model relates to the technical field of cable reels, in particular to a novel variable-frequency cable reel.

Background

The reduction gearbox of the original old cable drum is split and mainly comprises a bevel gear, a large gear ring, a hollow shaft, an adjusting nut and other parts. The drum rotates very well due to the influence of assembly technology and precision, and is easy to wear and break teeth under the condition that the bevel gear and the large gear ring are not well matched. The friction force is also great, the reaction torque of the winding drum is great, and the output force is great when the cable winding drum is used for paying off cables. If stuck, the cable is pulled. In the context of variable frequency control, because the cable on the cable drum is wound in a single layer, as the cable on the cable drum increases, the diameter is also large, and the crimping force increases. If the constant torque is controlled, the given force can be calculated only according to the diameter of the maximum circle, otherwise, the situation that the reel is not rotated occurs when the reel is maximum, but when the given force is not changed after the cable is put out, the cable is very tight, and the cable is pulled into a twist shape for a long time.
