3 Terms
3.1 The definitions of terms in this standard adopt the interpretations of GB2900. 3.2 Rotating body for stranding Rotating body for stranding The rotating part in the stranding equipment that makes the individual strands move around the central axis of the equipment to complete the stranding of the workpiece is referred to as the rotating body. The guide rod mechanism or the slewing bow is the stranding rotating body of the bundle stranding equipment. The simplified body and the slewing bow are the stranding rotating bodies of the tube stranding equipment. The cage is the stranding rotating body of the cage stranding equipment. The (rewinding) frame is the stranding rotating body of the coil stranding equipment. 3.3 Stranding cage section The stranding cage that completes the stranding of one layer of components in the cage stranding equipment is called a stranding cage section. It consists of an independent transmission gearbox, a braking device, a die pressing device and a stranding cage rotating body. It is named after the number of pay-off drums in the stranding cage, such as a 6-reel stranding cage section and a 12-reel stranding cage section. 3.4 Bobbin frame
A device or component for placing the pay-off drum or the take-up drum in the stranding rotating body. It consists of a drum support device and a tension device. 3.5 Revolution circle Revolution circle
The index circle formed by the supporting centers of the reels on the rotating body when the cage of the Y-type stranding equipment is in operation. 3.6 Rotation circle Rotation circle
The largest radial trajectory circle formed by the self-rotation of the reel rack and the reels on it due to back-twisting when the cage revolves. 4 Naming and code
