CNC Worm Cylindrical Gear Hardened For Auto-Trimming Lockstitch S/M

Mechanical Properties
High strength: When the auto-trimming lockstitch sewing machine works, the gear needs to transmit power and bear large bending stress and contact stress, DINGSCO uses medium carbon steel after quenching and tempering, or alloy carburizing steel carbcurizing and quenching to improve strength and hardness.
Good toughness: prevent tooth breakage during frequent starting, braking and impact, and ensure the reliability of gear work.
Abrasion resistance: The lockstitch sewing machine works continuously for a long time, and the gears continue to be meshed and friction, so it is necessary to improve the surface hardness and wear resistance of the gears and prolong the service life through suitable materials and heat treatment, such as surface quenching, carburizing, etc.

Transmission Accuracy
Precise tooth shape: Ensure the correct meshing of the gear, make the transmission ratio constant, achieve stable and accurate transmission, and reduce the motion error.
Low pitch error: Strictly control the manufacturing accuracy of the pitch to reduce the speed fluctuation and vibration during the transmission process.
Thermal stability: The relative sliding speed between the meshing teeth is large, and the friction generates more heat, so it is necessary to have good thermal stability, and through reasonable lubrication and heat dissipation design, it can prevent the decline of material performance, aggravation of wear and gluing and other problems caused by high temperature.
Large transmission ratio: Some parts of the automatic tangential lockstitch sewing machine require large transmission ratios to achieve deceleration, and the worm gear and worm can meet the needs with single-stage transmission and compact structure.

Smoothness
Suitable coincidence degree: The degree of coincidence is large, and the number of tooth pairs involved in the meshing is more, and the transmission is more stable, the coincidence degree of spur cylindrical gears is relatively small, and the coincidence degree of helical cylindrical gears is large, and the transmission is more stable.
Low vibration and noise: By optimizing the design, improving the manufacturing accuracy and reasonable assembly, the vibration and noise of the gear transmission are reduced and a quiet working environment is created.
