20CrMnTi Small module High-Speed Sewing Machine Gear For Garment Workshops
Industrial sewing machine gears are precision transmission gears specially designed for industrial sewing equipment such as lockstitch machines, overlock machines, interlock machines, pattern sewing machines, thread trimmers and compound feed sewing machines. Made of high-strength wear-resistant alloy steel through small-module precision machining, high-precision gear grinding and stable heat treatment, they are mainly used for power transmission in mechanisms including head drive, thread take-up, fabric feeding, shuttle rotating, thread trimming and presser bar lifting. Featuring stable operation, low noise, wear resistance, fast start-stop response and long service life, they are core basic components for industrial sewing machines to achieve high-speed, continuous and stable sewing.
Product Features
Small module and high precision, suitable for high-speed sewing conditions (5000～10000rpm).
Extremely smooth operation with low vibration and low noise for long-term continuous working.
Uniform tooth surface hardness, excellent wear resistance, not easy to pitting and abrasion.
Sensitive starting and reversing, with accurate action matching thread trimming and take-up mechanisms.
Compact structure and small size, suitable for narrow space of sewing machine heads.
Minimal heat treatment distortion, high dimensional consistency and strong assembly interchangeability.
Oil and dust resistance, adapting to long-term continuous production environment in garment workshops.
Transmission gears for computerized lockstitch machines, high-speed lockstitch machines and compound feed machines.
Gear components for overlock machines, interlock machines and heavy-duty sewing machines.
Precision gears for pattern sewing machines, embroidery machines and CNC sewing equipment.
Automatic thread trimming, thread take-up and fabric feeding mechanisms of sewing machines.
Transmission systems for zigzag machines, buttonhole machines, button sewing machines and bartacking machines.
Gear replacement and maintenance for various domestic and imported industrial sewing machines.
Product Advantages
Excellent high-speed performance, supporting stable operation up to 10000rpm.
Low noise and low vibration, significantly improving workshop working environment.
Wear and fatigue resistant, meeting 24-hour continuous production with long service life.
High transmission precision, ensuring even and beautiful stitches without skipping or deviation.
Strong interchangeability, directly replacing gears of brands such as Jack, Zoje, Brother, etc.
Small-module precision machining with compact structure, suitable for narrow head space.
Support customization based on drawings, suitable for modification of special sewing equipment.
Production Process
Clean oil and impurities inside gears, bushings, connecting rods and casing before assembly.
Install correctly according to assembly clearance to ensure uniform gear meshing without jamming.
Fill sewing machine oil or special grease to ensure high-speed lubrication.
Run low-speed test for 3～5 minutes and check running smoothness and noise.
Gradually increase speed to working speed and test synchronization of stitches and fabric feeding.
Lubricate regularly, clean fabric dust and debris to prevent jamming.
Regularly inspect gear wear and backlash change to ensure stable transmission.
