1) Description of Helical Gear Shaft
From the perspective of materials and manufacturing processes, helical gear shafts are shaft parts with helical gear structures
made of high-strength alloy steel (such as 40Cr, 20CrMnTi, etc.) through forging, cutting, heat treatment and other processes.
2) Advantage of Helical Gear Shaft
The material has high strength, high surface hardness, good core toughness, and excellent wear resistance and fatigue resistance
after heat treatment. The manufacturing process is complex, but it can ensure the accuracy of the gear
and the dimensional accuracy of the shaft, and improve the reliability and service life of the transmission;
Suitable materials and processes can be selected according to the needs of different working conditions, and the adaptability is strong.
3) Working Principle
Using the high strength and good mechanical properties of the material, it can withstand various forces and torques in the transmission process,
and ensure the meshing accuracy of the gears through the precise manufacturing process, making the power transmission process
stable and reliable, and reducing the failure caused by material or manufacturing defects.
4) Application of Helical Gear Shaft
It is suitable for timing gear shafts in automobile engines, drive shafts in precision machine tools, and other applications
that require high material properties and manufacturing accuracy.
