Spiral Bevel Gear
NOWARUN produces custom spiral bevel gears cut to the GLEASON or KLINGELNBERG system to match the exact driveline geometry of your machinery. Parts are manufactured to customer drawing across module 0.5 to 10 in carbon steel, alloy steel, or polymer. Achieving gear precision from DIN 3 to DIN 7, every set undergoes processes including milling, grinding, and application-specific heat treatment.

How It Is Made
- 1
Drawing evaluation and technical confirmation of the tooth system and gear module
- 2
Gear blank turning and preparation to specified mounting and bore dimensions
- 3
Spiral bevel tooth cutting using dedicated milling setups
- 4
Specified heat treatment applied to meet required hardness and case depth
- 5
Precision tooth grinding to achieve the target DIN gear accuracy class
- 6
Final inspection, cleaning, and protective packaging in crates, boxes, or cartons
Quality Control
- Tooth geometry and profile verification to ensure specified DIN 3 to DIN 7 precision
- Dimensional verification of bore, keyway, mounting distance, and outer diameter
- Hardness testing following carburizing, induction hardening, or quenching and tempering
- Protective packaging checks to prevent surface or tooth damage during export transit
Customization Options
- Custom tooth profiles cut to either GLEASON or KLINGELNBERG system standards
- Shaft mounting options machined to drawing including custom bores, keyways, and splines
- Specific module selection anywhere between module 0.5 and module 10
- Material and heat treatment matched directly to your operating load requirements
Compared With the Alternatives
| Alternative | Honest trade off |
|---|---|
| Straight bevel gears | Spiral bevel teeth engage progressively for smoother operation, but require proper bearing support for thrust loads |
| Catalogue stock bevel gears | Stock gears eliminate tooling lead times, but restrict your housing design to predefined bores and mounting distances |
| Worm gear sets | Spiral bevel gears provide higher mechanical transmission efficiency, though they do not offer intrinsic self-locking |
Use Guide
- Provide manufacturing drawings defining module, tooth count, pressure angle, and spiral hand
- Identify whether the gear pair requires the GLEASON or KLINGELNBERG tooth system
- Specify the target DIN accuracy grade so appropriate grinding processes are allocated
- Indicate material grade and required heat treatment parameters on the RFQ
- Ensure mating gears are installed at the designated mounting distance during final assembly
