Sewing M/C Bevel Gear With Arc Teeth For Compound Feed Lockstitch Sewing Machine

Bevel gears play a crucial role in the compound feed lockstitch sewing machine's power transmission system, particularly in transmitting motion at an angle. Here are the key roles and functions of bevel gears in a compound feed lockstitch sewing machine:

1. Power Transfer at an Angle: Bevel gears are used to transfer power between shafts that are not parallel to each other. In a compound feed lockstitch sewing machine, bevel gears are commonly employed to transmit motion from the main drive shaft to the feed mechanism, which typically consists of feed dogs, needle feed, and walking foot. These gears allow power to be transferred efficiently and smoothly, even when the shafts are oriented at different angles.
2. Change of Direction: Bevel gears can change the direction of rotation between two connected shafts. In a compound feed lockstitch sewing machine, bevel gears are often used to redirect the rotational motion from the main drive shaft to the feed mechanism, which requires motion in a different direction. This change of direction enables the synchronized movement of the feed dogs, needle feed, and walking foot, ensuring proper fabric feeding during the sewing process.
3. Torque Transmission: Bevel gears are capable of transmitting torque effectively, allowing the power generated by the machine's motor to be efficiently transferred to the feed mechanism. This torque transmission is crucial for driving the feed dogs, needle feed, and walking foot with sufficient force to handle various fabric thicknesses and maintain consistent feeding during sewing.

A compound feed lockstitch sewing machine is a type of sewing machine commonly used in industrial settings for heavy-duty sewing tasks. It is designed to handle a wide range of materials, including thick or layered fabrics, leather, upholstery, and other heavy fabrics. Here are some key features and characteristics of a compound feed lockstitch sewing machine:

1. Compound Feed Mechanism: The compound feed mechanism is a distinctive feature of this type of sewing machine. It involves three feeding components working together to ensure smooth and even fabric feeding. These components typically include the feed dogs, needle feed, and walking foot. The feed dogs grip and move the fabric from the bottom, while the needle feed mechanism moves the fabric in coordination with the sewing needle. The walking foot, also known as a top feed, further assists in feeding multiple layers of fabric evenly.
2. Lockstitch Formation: Compound feed lockstitch machines produce a lockstitch, which is a strong and secure stitch commonly used in 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. Heavy-Duty Sewing Capability: These machines are designed to handle heavy-duty sewing tasks. They have a robust construction and powerful motor to sew through thick materials, multiple layers, and challenging fabrics. They are commonly used in industries such as upholstery, automotive, leather goods manufacturing, and other applications that require sewing heavy fabrics or materials.
4. Versatility: Compound feed lockstitch machines offer versatility in terms of stitch patterns and sewing applications. They can typically perform straight stitch, zigzag stitch, and other decorative stitches. They can be equipped with various presser feet, needle sizes, and thread types to accommodate different sewing needs.
5. Durability and Reliability: Due to their industrial-grade construction, compound feed lockstitch machines are built to withstand continuous and demanding sewing conditions. They are known for their durability, reliability, and long-lasting performance in industrial settings.
