Spiral Bevel Gears
Spiral Bevel Gears & Pinions ground manufactured on the Gleason 280G in closed loop (Gleason GEMS® Design -Ground-Measured and closed loop to maintain the design).
Spiral Bevel Gears and Pinions Ratios 1:1 – 8:1
1Mn – 10Mn 22mm tooth depths Typ. 25° – 45° Sprial Angles
Ø15mm – Ø280mm
Completing with duplex tooth taper
Gear generated or FORMATE (plunge) ground
Gleason GEMS® used by Ondrives for Spiral Gear Design.
3D gear and pinion graphics with animation.
Combined ease-off and TCA for pinion and gear.
Interactive tooth surface and ease-off correction and optimization.
Real blank geometry for both pinion and gear.
2D tooth profiles along the face width.
2D/3D loaded TCA, including interactive root bending stress and contact stress output with S-N Curves



Spiral – Hypoid Gears and Pinions
Ondrives are able to manufacture spiral bevels and hypoids in different styles and types. Spiral bevel teeth designed and made to give an optomised output.

Hypoid Gears
Hypoid gears offset Ground and Pinions
Ground Hypoid pinions and gears manufactured with offset Ratios 3:1 – 10:1
1Mn – 10Mn 22mm tooth depths.
Upto Ø280mm
Offsets 10%-20% of pitch diameter typical is 10-15%
Enlarged pinion compared to spiral bevel pinion

Gleason GEMS® Hypoid TCA
High Ratio Hypoid
HRH and SRH gears & pinions extreme high offsets with high ratios.
Ground HRH pinions and gears manufactured ratios 5:1 – 100:1
1Mn – 2.25Mn
Parallel tooth depth
High pinion offsets 20-33% of outside diameter of gear
