Spiral spur gear
Spiral spur gears provide smooth tooth engagement across parallel shafts, manufactured by NOWARUN strictly to your drawing rather than sold from off-the-shelf stock. Available in module sizes from 0.5 to 10, these gears are produced in carbon steel, alloy steel, stainless steel, or polymer to gear precision grades from DIN 5 to DIN 10. Tooth cutting processes include hobbing, shaping, shaving, and grinding to match the mechanical requirements and tolerance profile of your equipment.

- 5
Tooth grinding and finishing operations to achieve specified DIN precision grades
- 6
Surface treatment application such as plating, Geomet, Dacromet, E-coating, or oiling
- 7
Final dimensional inspection, laser engraving of part markings, and export packaging
Quality Control
- Gear tooth profile and lead verification against the designated DIN 5 to DIN 10 grade
- Critical bore, hub, and keyway dimensional checks against drawing tolerances
- Hardness testing after carburizing, carbonitriding, QT, or induction hardening cycles
- Surface treatment thickness and visual adhesion checks across coated or plated surfaces
- Packaging inspection to prevent transit damage using PP bags, cartons, crates, or boxes
Customization Options
- Manufactured entirely to customer technical drawings, mounting dimensions, and tooth counts
- Choice of manufacturing route including hobbing, shaping, shaving, and grinding to fit budget and precision targets
- Material selection tailored to operating requirements, including foreign alloy equivalents
- Targeted heat treatments from surface induction hardening to full quench and temper
- Protective finishing options from simple rust preventative oiling to Geomet, Dacromet, and E-coating
Compared With the Alternatives
| Alternative | Honest trade off |
|---|---|
| Straight cut spur gears | Spiral spur teeth engage gradually for smoother and quieter power transmission, but create axial forces that require thrust support |
| Commercial stock spur gears | Stock gears ship quickly but lack custom bore features, application-matched heat treatments, and tailored DIN grades |
| Unground cut gears | Ground tooth profiles hit DIN 5 precision for high-speed reliability, whereas shaving or hobbing alone costs less for moderate speeds |
Use Guide
- Submit complete manufacturing prints indicating module, tooth number, helix angle, face width, and bore tolerances
- Clearly define the target gear precision between DIN 5 and DIN 10 to establish the proper grinding or shaving route
- Specify core hardness and case depth requirements if carburizing, carbonitriding, or induction hardening is selected
- Identify any corrosive service conditions so appropriate surface treatments like Geomet, Dacromet, or E-coating are applied
- Ensure mating shaft alignment and adequate thrust bearing capacity are provided to handle the gear's helix angle
