Helical gears from Feida Machinery, a chinese manufacturer and exporter,are cylindrical gears with helical teeth cut at an angle to the gear axis.The basic parameters of these products include helix angle,normal module,transverse module,normal pressure angle,and transverse pressure angle. Our Helical Gears series includes Metal Helical Gears and Plastic Helical Gears.
The common material used for these products is low-alloy carburizing steels(e.g., 20CrMnTi,SCM415),which has excellent load-carrying capacity and wear resistance and is suitable for high-speed, and heavy-load applications.By carburizing+quenching+tempering, it achieves a hardness of HRC58-62.
Compared to spur gears ,helical gears have distinct characteristics :
1. Their teeth follow a helical path with a helix angle,which come into and out of contact progressively.
2. Mesh smoothly and quietly,reducing noise and vibration.
2. Their load capacity is improved by 30-50% due to longer total contact line during meshing.
4.Produce axial trust,requiring bearings that can handle axial loads.
5.Have slightly lower transmission efficiency about 96-99% per stage.
6.Are machined by special machine tool .
Helical gears are best choice for applications requiring high speed,heavy load ,low noise,long life and high reliability,including automotive transmissions,machine tool spindles,aviation drives,etc.
In Feida’s own factory,We have a complete production line and quality control system to ensure our production capacity fully meets customer needs .
Based on your product drawings or samples, we offer both rapid prototyping within 1-7 days and large-scale production in as little as 15-20 days, adhering to stringent quality requirements.
