Description
This product is the Presser Foot Lifting & Thread Trimming Driving Gear (Finished Product), a dedicated spur gear for sewing equipment. Its core technical parameters are precisely tailored to the transmission requirements of sewing machinery: pressure angle of 20°, module of 0.8, number of teeth of 30, helix angle of 0°, inner diameter of 10mm, addendum circle diameter of 25.6mm, total length of 12mm, and a unit weight of only 0.025kg. The lightweight design can effectively reduce the operating load of the equipment.
Made of high-quality 20CrMo alloy structural steel, the product is manufactured through a strict multi-step process: normalizing pretreatment to improve material toughness → turning to shape the basic dimensions → screw hole machining and reaming to ensure assembly accuracy → hobbing to form precise tooth profiles → heat treatment to enhance tooth hardness and wear resistance → shot blasting to optimize surface quality → secondary reaming to further improve assembly fit → screw assembly to complete the finished product.
As the core power transmission component for the presser foot lifting and thread trimming actions of sewing machines, this gear can stably transmit power, ensure the synchronization and smoothness of the equipment’s presser foot lifting and thread trimming movements, and is widely used in the transmission systems of various industrial sewing machines and household multi-functional sewing machines.
