1.2 Winding parameters for circular cross-
section steel wire rings
The selection of bead wire winding parameters mainly
includes: bead wire core diameter, outer winding wire diameter,
winding lead number, winding layer number, number of wires
per layer, winding angle, etc. The selection results can form
different specifications and different wire arrangement patterns
of circular bead wires.
The winding process of the circular steel wire ring
can be described as follows: the core of the steel wire ring Figure 3 Schematic diagram of wire arrangement after

plane, while the outer steel wire performs reciprocal curved
motion along the axial direction of the steel wire ring core (i.e., During the winding process, the core of the steel wire
circular motion around the steel wire ring core within the XOZ ring rotates once within the XOY plane, and the outer winding
plane). The two motions are coupled to form a helical motion, steel wire completes N lead spirals within the XOZ plane. For
as illustrated in figures 2 and 3. every lead of winding, the steel wire rotates by a little more
than one revolution, ensuring that the end of the outer winding
steel wire connects with the head of the steel wire in that layer
after completing N leads. After winding one layer, a connecting
point appears where the ends of the outer winding steel wire
meet, and a copper sleeve is installed for connection.
