Description

IWF2-079 Finished Pinion

This product is a precision finished helical gear dedicated to sewing equipment, made of 20CrMo alloy steel with both high strength and wear resistance. It features precise core parameters: a pressure angle of 20°, module of 0.9769, 15 teeth, speed ratio of 2, right-hand helix angle of 45°, inner diameter of φ9.52mm, outer tooth diameter of 22.67mm, total length of 16.7mm, and a net weight of only 0.0275kg. Its compact and lightweight structure can meet the lightweight transmission requirements of sewing machinery.
The production process strictly follows the precision workflow: normalizing – turning – gear hobbing – heat treatment – shot blasting – reaming. Each process is closely controlled to ensure the gear has high tooth profile accuracy, stable transmission meshing and low operation noise. It can effectively guarantee the efficient and continuous operation of sewing equipment, and serves as a key component of the core transmission system of sewing machinery.

IWF2-078 Finished Gear Wheel

This product is a high-precision finished helical gear for sewing equipment, crafted from 20CrMo alloy steel that balances toughness and durability.
