CNC Spiral Gear High Accuracy For Compound Feed Lockstitch S/M

Change the direction of transmission

The internal structure of the compound feed lockstitch sewing machine is complex, and the layout of the power source and the actuator needs to be reasonably planned. This pair of helical bevel gears is conical, which can realize the transmission between intersecting shafts, and can usually change the direction of power transmission by 90°, so that the power transmission between power components such as motors and other working parts is smoother, and it is convenient for the compact layout of mechanical structure.

Transmission smoothness

The tooth line of the helical bevel gear is oblique, and in the process of meshing, the degree of overlap is large, that is, the number of tooth pairs participating in the meshing at the same time is more. When the compound feed lockstitch sewing machine is working, it can effectively reduce vibration and impact, and reduce the operating noise. The smooth transmission can ensure the stability of the feeding process, make the stitches uniform and beautiful, avoid the uneven stitches and skipping stitches caused by the unstable transmission, and ensure the quality of sewing products.

Carrying capacity

When the compound feed lockstitch sewing machine is working, especially when sewing thick materials or carrying out long-term continuous operation, the transmission parts will bear a certain alternating load. After heat treatment, the alloy steel material has high tooth surface hardness, which can effectively resist wear, pitting and other failure forms, reliably transmit power, and is not easy to occur tooth surface wear and tooth root breakage, so as to meet the needs of lockstitch sewing machine for long-term stable work.

Accuracy adaptation

In order to ensure the sewing accuracy, the compound feed lockstitch sewing machine has strict requirements for the accuracy of the transmission parts. From the perspective of appearance regularity, this pair of gears should be able to meet the requirements of dimensional accuracy, tooth shape accuracy and position accuracy. The accurate modulus and number of teeth ensure the accuracy of the transmission ratio, the high-precision tooth shape ensures the smooth meshing of the gear, and the position accuracy indicators such as the strictly controlled tooth direction error make the load evenly distributed, and can cooperate well with other precision parts of the lockstitch sewing machine to achieve precise transmission.

The compound feed lockstitch sewing machine is a kind of industrial sewing machine, which works together through a plurality of feeding mechanisms to accurately convey the sewing material according to the set direction and speed, and at the same time the machine needle does the up and down puncture movement, and cooperates with the shuttle bed or rotary hook to complete the hooking and winding action to form a stitch, so as to realize the stitching of the sewing material. It is widely used in sewing and processing of clothing, bags, leather products, etc.
