Custom Helical Gears Manufacturer

## Product Features Helical gears offer significant advantages over spur gears including quieter operation, higher load capacity, and smoother power transmission. The angled teeth engage gradually, reducing noise and vibration. Our helical gears are manufactured using CNC hobbing and grinding machines with strict quality control at every stage. Each gear undergoes dimensional inspection, hardness testing, and tooth profile verification. ## Technical Specifications We produce helical gears with helix angles from 15° to 45° in both left-hand and right-hand configurations. Module range covers 1 to 16 with outer diameters up to 1500mm. Material options include 20CrMnTi for general applications, 40Cr for medium-duty use, and 42CrMo for heavy-duty applications requiring high fatigue strength. All gears receive appropriate heat treatment per application requirements. ## Applications Helical gears are preferred in: - High-speed gearboxes and reducers - Heavy machinery and mining equipment - Marine propulsion systems - Wind turbine gearboxes - Automotive transmissions - Oil and gas pumping systems ## FAQ Q: Why choose helical gears over spur gears? A: Helical gears provide smoother, quieter operation with higher load capacity due to the gradual tooth engagement. They are preferred for high-speed applications where noise and vibration must be minimized. Q: What helix angle should I choose? A: Typical angles are 15-30°. Higher angles (30-45°) provide smoother operation but generate higher axial thrust loads that must be accommodated by bearings. Q: Can you match existing gear specifications? A: Yes. Send us your existing gear drawing or sample, and we can reverse-engineer to match dimensions, material, and heat treatment specifications.
