Industrial Sewing Machine Gear with High Precision Bevel and Gleason Teeth Profile

What are the characteristics of Pulling machine gear?

The puller is a special equipment used in the shoemaking industry. It is mainly used to stretch and fix the upper material to the sole to ensure that the upper and the sole are closely fitted.

As the core transmission component of the pulling machine, the gears mainly include:

Power transmission: transfer the power output from the motor to various working parts of the pull-up machine through gears

Speed adjustment: The working speed of the equipment is adjusted through the matching of different gears to meet the needs of different materials and processes.

Synchronous operation: Ensure the coordinated operation of all parts of the equipment, and improve production efficiency and product quality.

Advantages

High precision: The accuracy of gear machining directly impacts transmission efficiency and stability, so CNC technology is often used to ensure precision.

Wear resistance: Gears must endure high loads over time, requiring wear-resistant materials or surface treatments.

Fatigue resistance: Gears need strong fatigue resistance to last longer.

Lubrication and cooling: The lubrication system must ensure good performance, reduce friction and noise, and provide necessary cooling.

As the core component of shoemaking equipment, the performance of the pull-up gear is directly related to the stability and production efficiency of the equipment. Choosing the right gear type, ensuring machining accuracy, optimizing the lubrication system and regular maintenance are the key to ensuring efficient operation of the pull-up machine.
