Description
This product is the 12925004 small helical gear, classified as a helical gear type, and serves as a dedicated gear component for sewing equipment. It features clear core technical parameters: pressure angle of 14.5°, module of 0.9769, number of teeth of 15, helix angle of 45°/L, inner diameter of 9.52mm, addendum circle diameter of 22.67mm, total length of 17mm, and a unit weight of only 0.0171kg. With a compact and lightweight structure, it is suitable for small-scale transmission systems.
The gear is made of high-quality alloy structural steel 20CrMo, manufactured through a rigorous multi-process workflow: normalizing pretreatment → turning → threaded hole machining → reaming → hobbing → heat treatment strengthening → shot blasting → secondary reaming → facing → nitriding heat treatment → screw assembly. Among these processes, nitriding heat treatment significantly enhances the surface hardness and wear resistance of the gear, ensuring tooth surface precision and transmission stability. Multiple reaming procedures guarantee assembly dimensional accuracy to meet the precision matching requirements of equipment.
Designed specifically for sewing equipment, this gear offers stable transmission, low noise and high load-bearing capacity. It can effectively adapt to the high-frequency operation conditions of sewing machinery, ensuring the reliability and durability of equipment operation.
