Zigzag Sewing Machine Gear Low Noise Small Module Gear 11/22 Teeth

Cam Mechanism: Zigzag sewing machines typically employ a cam mechanism that controls the movement of the needle and the fabric feed. The cam is a specially shaped disc or plate that rotates and interacts with the machine's gears to produce different stitch patterns, including the zigzag stitch.

Gear Ratio: The gear ratio in zigzag sewing machines determines the speed and power transmission between the motor and the cam mechanism. Different gear ratios are used to achieve various stitch lengths and widths.

Adjustable Stitch Width: Zigzag sewing machines feature gears that allow for the adjustment of stitch width. By changing the position of the cam or adjusting the gear mechanism, users can modify the width of the zigzag stitch.
