High-Efficiency And Stable 20606 4400 Twin-Needle Machine Gears with Steel and Gleason Teeth Profile

What are the characteristics of 20606, 4400 twin-needle machine gear?

Gears are the core transmission components in double-needle machines, mainly used to transmit power and motion, ensuring the coordinated operation of various parts of the machine. In double-needle machines, gears transfer power from the driving part to the sewing part through meshing action, achieving the accuracy and stability of sewing operations.

Advantages

Ultra-smooth transmission: The gears mesh and transmit power extremely smoothly. When the machine is running, there's very little vibration and noise, making it really comfortable to use.​

Precise transmission ratio: This is crucial. It ensures every sewing action is accurate and in place, resulting in neat and uniform work with no deviations.​

Exceptional durability: The gear structure is built to be tough. Even when running at high intensity for long periods, they hardly break down and have a really long service life.​

High transmission efficiency: There's very little power loss during transmission. The power gets transferred effectively, which not only saves electricity but also ensures the machine has sufficient power to work more efficiently.​

A twin-needle machine is an industrial sewing equipment, widely used in sewing operations in industries such as clothing, shoes and hats, luggage and bags. Gears are mainly used in double-needle machines in the following scenarios:​

Power transmission: Transfer the motor power to the sewing mechanism, driving the movement of the needle bar and the feed dog.​

Speed adjustment: Realize the adjustment of sewing speed through different gear combinations.​

Motion coordination: Ensure the actions of the needle bar and the feed dog are synchronized, improving the sewing quality.​
