Spiral Cylindrical Gears Transmission For 7200 New High-Speed Lockstitch Sewing Machine

7200 Sewing M/C Cylindric Spiral Gear For 7200 New High-Speed Lockstitch Sewing Machine

In the context of a high-speed lockstitch sewing machine like the 7200, the role of a cylindrical gear can vary depending on its specific placement and function within the machine. Here are some roles that cylindrical gears play in sewing machines:

1. Power Transmission: Cylindrical gears are often used to transmit power from one component to another within the sewing machine. They help transfer rotational motion and torque between different parts of the machine, such as the motor, shafts, and mechanisms involved in driving the needle and feed system.
2. Drive System: Cylindrical gears can be part of the machine's drive system, assisting in the transmission of power from the motor to various components. They help ensure the efficient and synchronized movement of different machine parts, allowing the machine to operate at high speeds.
3. Needle Drive: Cylindrical gears may play a role in driving the needle mechanism of the sewing machine. They help transmit power from the motor to the needle bar, which controls the up-and-down movement of the needle during stitching. The gears ensure precise and synchronized needle movement, contributing to accurate stitching at high speeds.
4. Feed System: Cylindrical gears can also be involved in driving the feed system of the sewing machine. The feed system advances the fabric during stitching. Cylindrical gears help transmit power from the motor to the feed dogs or other feeding components, enabling smooth and synchronized fabric feeding at high speeds.

The 7200 is a model number typically associated with high-speed lockstitch sewing machines manufactured by various brands. Here are some general features and characteristics in 7200 new high-speed lockstitch sewing machine:

1. Speed: High-speed lockstitch machines are designed to sew at significantly faster speeds compared to standard sewing machines. They can typically achieve stitch rates ranging from 4,000 to 10,000 stitches per minute (SPM) or even higher. The increased speed helps improve productivity and reduce sewing cycle times.
2. Lockstitch Formation: High-speed lockstitch machines produce a lockstitch, which is a strong and secure stitch commonly used in various sewing applications. The lockstitch is formed by the upper thread from the sewing needle interlocking with the lower thread from the bobbin, creating a tight and durable stitch.
3. Motor Power: These machines are equipped with powerful motors to support high-speed sewing. The motor provides the necessary driving force to move the needle, feed mechanism, and other machine components at high speeds without compromising stitch quality.
4. Durability and Stability: High-speed lockstitch machines are built with sturdy construction and robust components to withstand the demands of continuous high-speed sewing. They are designed to maintain stability and minimize vibrations during operation, ensuring accurate stitching even at high speeds.
5. Thread Tension Control: These machines often feature advanced thread tension control mechanisms to ensure consistent and balanced thread tension throughout the sewing process. Proper thread tension is crucial for achieving high-quality stitches, especially when sewing at high speeds.
6. Versatility: High-speed lockstitch machines are versatile and can handle a wide range of fabrics and sewing applications. They can sew various types of materials, from lightweight fabrics to heavy-duty fabrics, making them suitable for industries such as garment manufacturing, upholstery, automotive, and more.
