Abstract
The utility model relates to a damping structure for a draw drum of a cage stranding machine, and pertains to the electrical wire and cable equipment field. The prior art is to control the pay-off tension of the draw drum by adjusting the tightness of the belt, and has the disadvantages of unstable pay-off tension, and uneven pay-off tension between various cradle draw drums. The utility model controls the pay-off tension by adjusting the pole gap between various damping disks, and comprises passive damping disks, active damping disks, an adjustment handle, sliding bushes for active damping disks, a drive shaft, a scale indicator, a fixing base for passive damping disks, bearings, bearing holders, and cradle bodies. The pay-off tension can be adjusted by simply rotating the adjustment handle. The moment after adjustment will remain constantly stable, and not change against temperature, time and the relative slip speed, due to the non-contact friction between various damping disks made of permanent magnets. The utility model ensures a stable pay-off tension in the entire operating process, allows the convenient adjustment of the moment, and realizes the even pay-off tensions between all the cradle draw drums through the gap scale indicator.
