Helical Gear Shafts

Helical gear shafts from Feida Machinery are mechanical components that integrates the functions of shafts and helical gears.They provide smoother transmission,lower noise & vibration, and higher load‑bearing capacity because their teeth are arranged along the spiral direction, resulting in a larger contact ratio.

In the manufacturing process, Feida typically adopts high-precision machining (such as turning, milling, grinding, and gear hobbing) to ensure the accuracy of gear teeth and the coaxiality of the shaft.The entire production process is as follows.

Common materials for helical gear shafts include high-strength alloy steels (e.g., 40Cr, 20CrMnTi) and carbon steels, which can be further enhanced through heat treatment processes (such as quenching & tempering,carburizing & quenching) to improve hardness, wear resistance, and fatigue strength.

Application

Helical gear shafts are suitable for the applications requiring smoother transmission and higher load-bearing capacity.The typical applications include automotive gearboxes, industrial reducers, robot joints, and other equipment.

FAQ

1.What is the precision grade of your gears and shafts respectively?

The precision of gears is ISO/DIN grade 5 to 10, and that of shafts is grade 6 to 10.

2.What is the module of your gears and shafts respectively?

The module range of gears is M0.5 to M20,and that of shafts is M0.5 to M5.

3.When should gear shafts be preferred?

Gear shaft solutions are usually preferred under working conditions with compact space, high transmission precision requirements, high operation stability requirements, and strict control of noise and vibration.
