As the core component of textile machinery, the structural design of weaving shafts directly affects the stability of yarn transmission and the efficiency of equipment operation. The typical design adopts high-strength alloy steel hollow cylinder as the main body, balancing lightweight and bending strength; Both ends are equipped with precision bearing seats and flanges to ensure dynamic balance during high-speed rotation. The surface has undergone mirror polishing treatment, with a roughness lower than Ra0.8 μ m, effectively reducing yarn friction loss. The innovative modular components include a quick detachable conical chuck, an adaptive tension compensation device, and an anti twist guide groove.
Modern intelligent models are increasingly incorporating carbon fiber composite material lamination technology, which enables the shaft body to achieve electromagnetic shielding function while maintaining rigidity. Under special working conditions, a constant temperature control system is also equipped to avoid radial runout caused by thermal expansion. The reinforced rib layout optimized through finite element analysis can withstand radial loads of over 2000N without deformation. This scientific structural design not only extends the service life, but also adapts to various yarn types from cotton spinning to synthetic fibers, providing good warp yarn supply guarantee for high-speed shuttleless weaving machines.
