SMALL SEWING MACHINE PLASTIC 9 TEETH GEAR

A 9-tooth sewing machine gear could potentially play several roles in a sewing machine, depending on its size, material, and specific position within the mechanism. Here are some possibilities:

Bobbin Winder Gear:

A9-tooth gear is used as the driver gear for the bobbin winder mechanism. This gear meshes with a larger gear on the main drive shaft, causing the bobbin winder spindle to rotate at a faster speed. This allows for efficient winding of the bobbin thread with minimal effort from the user.

Feed Dog Driver Gear:

A9-tooth gear is used to drive the feed dogs, which move the fabric through the machine during sewing.
This gear could mesh with a larger gear on the main drive shaft or with another intermediate gear in the system. The specific number of teeth on the gear would determine the ratio of the rotation speed between the drive shaft and the feed dogs, thus influencing the stitch length.

Gear for Tension Adjustment:

Some sewing machines might utilize a 9-tooth gear as part of the tension adjustment mechanism. This gear is involved in adjusting the tension of the upper thread or the bobbin thread. By changing the position or meshing of this gear with other gears, the tension on the thread can be fine-tuned for different fabrics and sewing techniques.

Accessory Attachment Gear:

Certain sewing machines have features like automatic needle threading or buttonholing mechanisms that might employ small gears like a 9-tooth gear. This gear could be part of a complex system of gears and levers that drive the specific function of the accessory attachment.

Size and material:

Smaller, plastic gears are more likely involved in tension adjustment or accessory functions, while larger metal gears typically handle driving mechanisms like the bobbin winder or feed dogs.

Position within the machine:

Observe where the gear is located and how it meshes with other gears in the system. This can provide clues about its role in the overall operation.

Machine manual:

Consulting the user manual for your specific sewing machine model will reveal the exact function of each gear and its role in the machine’s operation.
